We're building the infrastructure that makes autonomous AI safe for enterprise deployment. Not governance theatre. Not compliance checkboxes. Actual technical systems that can monitor, quantify, and govern AI agents operating with autonomy in production environments. If you've been following the trajectory from static models to agentic systems—and the corresponding explosion in risk surface area—you know why this matters now. About governr governr is the AI risk platform for regulated enterprises. We provide complete AI visibility, real-time risk eval and quantification, and audit-ready compliance docs for enterprises deploying agentic AI. We've built the industry's most comprehensive AI risk assessment framework: We're currently in active discussions with tier-1 financial institutions and have secured design partners with leading firms navigating the shift from analytical AI to agentic systems. The market timing is critical: enterprises are deploying agents at scale, regulators are demanding governance frameworks, and existing Third-Party Risk Management (TPRM) platforms have near-zero AI-risk depth. We have an estimated 18-24 month competitive window before large incumbents build comparable capabilities to stay relevant. The Role As an Agentic Developer at governr, you'll build the core systems that monitor, analyse, and govern autonomous AI agents in production. This isn't traditional software engineering with well-worn patterns. You're designing architectures for problems that didn't exist 18 months ago. You'll be responsible for: • Agent Monitoring Infrastructure: Build real-time systems that track agent behaviour across risk factors including agent-to-agent interactions, privilege escalation attempts, emergent capability detection, and behavioural drift from baseline parameters, • Risk Assessment Engine: Design algorithms that quantify AI risk in financial terms (£X exposure), map behaviours to regulatory requirements, and detect cascade failures before they propagate through multi-agent systems, • Protocol Integration: Implement monitoring for agent communication protocols (Model Context Protocol, Agent2Agent, Agent Connect Protocol) as they mature, ensuring authenticated and logged inter-agent communications, • Anomaly Detection: Develop ML systems that identify when agents exhibit unexpected strategies, attempt unauthorized actions, or drift from intended behaviour—catching issues before regulators do, • Evidence Generation Systems: Build architectures that automatically capture audit trails, decision provenance, and compliance evidence without impacting agent performance Core Requirements (Non-negotiable) Technical Depth: • 3 - 12+ years building production systems at scale • Expert-level proficiency in Python, Rust, or Go (you write systems that can't fail) • Deep understanding of distributed systems, real-time data processing, and observability architectures • Production ML/AI experience: You've deployed models, debugged their failures, and built monitoring around them • System design mastery: You can architect for reliability, scalability, and auditability simultaneously Domain Knowledge: • Understanding of agent architectures: autonomous decision-making, goal-directed behaviour, tool use, memory systems • Familiarity with AI safety concepts: alignment, interpretability, robustness, adversarial examples • Experience with monitoring/observability: instrumentation, logging, tracing, alerting in complex systems Working Style: • You ship to production regularly and own what you deploy • You write documentation that others can actually use • You thrive in ambiguity and define requirements through first principles • You communicate technical concepts clearly to non-technical stakeholders Highly Valued (Differentiated Candidates) • Publications or research in multi-agent systems, reinforcement learning, AI safety, or agent architectures • Experience at AI labs (Anthropic, OpenAI, DeepMind) or leading AI research groups, • Production experience with agents: LangChain, AutoGPT, CrewAI, or custom agent frameworks • Regulated industry background: Financial services, healthcare, or other domains with compliance requirements, • Security/threat modelling expertise: Understanding of adversarial AI, prompt injection, or system security • Real-time systems experience: Trading systems, fraud detection, or other low-latency critical infrastructure, • Open source contributions in relevant domains (AI frameworks, monitoring tools, security infrastructure) Bonus Points (Nice to Have) • Understanding of regulatory frameworks (EU AI Act, California AI, GDPR, DORA, FCA, OCC, FINRA guidance), • Experience with compliance/audit systems or GRC platforms, • Background in formal verification or theorem proving, • DevSecOps or infrastructure-as-code expertise, • Track record of technical leadership or architecture ownership Who Thrives Here You read AI safety papers for fun. You've built production systems where failure has real consequences. You're excited by the idea of being the first person to solve a category of problems that didn't exist last year. You care about getting it right, not just getting it done. When someone asks "can we monitor that?" your first instinct is to figure out how, not to explain why it's hard. You're comfortable with the early-stage start-up reality: fewer guardrails, more ownership, rapid iteration, and direct impact on company trajectory. You want to define the product, not just implement specifications. You're intellectually curious about the intersection of AI capabilities and regulatory constraints. You find it genuinely interesting that the EU AI Act requires "human oversight" but doesn't define what that means for autonomous agents. You're mission-aligned: You believe AI agents will transform how organizations operate, but only if we solve the governance problem. You want to be the person who solves it. Why Now / Why governr Market Timing: Autonomous AI is moving from research to production. McKinsey estimates $2.6T-$4.4T annual value from agentic AI. 80% of organizations report risky agent behaviours. Regulators are demanding guardrail frameworks. The infrastructure layer doesn't exist yet. We're building it. Technical Challenge: You'll solve problems that have no Stack Overflow answers. Agent-to-agent security. Cascade failure prevention across multi-agent systems. Emergent capability detection. Financial quantification of non-deterministic systems. This is legitimately hard, novel work. Category Leadership: We have 18-24 months before large incumbents build comparable depth. First-mover advantage in category creation is real. You'll help define what "AI governance" means. Team Quality: Co-founders with deep financial services + AI expertise. Advisors including Dr. Ayman Hindy, Marcel Cassard, and leading figures in AI, high frequency risk management and financial regulation. Early team of sharp, mission-driven builders. Learning Curve: You'll gain expertise in cutting-edge AI architectures, enterprise software, regulatory frameworks, and category creation simultaneously. This is one of those roles you look back on as career-defining. Impact Leverage: Every system you build enables safe AI adoption for enterprises managing billions in assets. Your code directly influences whether organizations can deploy autonomous agents responsibly. What We Offer Compensation: very competitive salary + equity in a fast-growing company with clear path to Series A Team: Reporting to Co-Founder Chief Product Officer, working directly with founders on product direction Work Environment: London, New York - focus on outcomes over presence Growth: Ownership of major product areas from day one. Technical leadership opportunities as team scales. Direct exposure to customers, investors, and strategic decisions. Resources: Modern tech stack, freedom to choose tools, Mission: Build the infrastructure that makes autonomous AI safe for society. Not many teams can say their technical work has direct regulatory impact. How to Apply If you're excited about building unprecedented monitoring systems for autonomous agents, working at the intersection of AI safety and enterprise software, and defining an emerging category—let's talk. Send your resume, GitHub/portfolio, and a brief note on what excites you about this problem space to and . Include: • Links to relevant work (code, papers, projects, or systems you've built) • What you're currently reading/learning in the AI agent space • One technical challenge you'd be excited to solve at governr We review applications on a rolling basis and move quickly for strong candidates. First round is a technical conversation with the Co-Founder, not whiteboard hazing. We're evaluating you as much as you're evaluating us. Come with questions about our technical approach, roadmap, or market positioning. The best conversations are mutual discovery. governr is an equal opportunity employer. We believe diverse teams build better products and welcome applications from candidates of all backgrounds. Ready to build the governance layer for autonomous AI? We're ready for you.

Bermondsey Electronics is a contract electronics development company looking for an embedded software developer to expand the team. The successful applicant will work on a wide variety of systems, with different targets and design goals, based from the office in Bermondsey. This role is also open to motivated graduates or early-career engineers who have a good understanding of embedded C and are keen to develop their skills quickly. Candidates with limited professional experience are welcome, provided they are comfortable working hands-on with code and hardware, learning new platforms rapidly, and moving between different projects as required. We need a new engineer to be involved in peripheral and board bring-up. This means testing PCBs coming in from clients. Clients have occasionally tested boards but not always, and usually not fully. They might not have the skills or might not know how a specific peripheral works. Our job is to prove the board fundamentally works, and develop or debug drivers as necessary. Higher level application code is usually done by those specialists and is not expected to be a fundamental part of this role. It's a useful skill if you have it, though. In the last year, this has meant working with STM32, DA1453x, NXP iMX RT and RW6xx platforms, iMX 8M Plus and Nano. Software platforms range from bare metal to FreeRTOS to Zephyr, through Linux and all the way up to Android. At each stage, clients have either not been able to supply drivers, or a delivery from a supplier has had to be debugged or modified. With that done, the PCB is handed off to application developers, or the client will issue us another board to repeat the cycle. Suppliers usually deliver drivers in C. These are often of unknown quality. They may need configuration, and sometimes a device tree. As examples: We ported TI's CC3351 driver to STM32 and brought up lwIP on FreeRTOS We brought up a new iMX8MP Linux platform using LVDS and a bespoke RFID driver We rewrote an ESP32 bootloader for a client to update partition tables OTA We tested and verified RW610 power modes in Zephyr We rewrote the STM32 Eclipse ThreadX USB Audio Host driver to support USB MIDI We debugged an Infineon WiFi driver low power mode on Android on iMX8MP Typically LLMs do not have enough training data to help. They usually cannot work out schematic errors, or spot placement issues on a board. If you use LLMs heavily, you are unlikely to find them as useful in this role. It can mean writing and/or debugging drivers like SPI, DAC or LVDS. Typically test and measurement gear is needed, e.g. logic analyser, scope, bench power supply etc. There can be a lot of time configuring demo code to run in the mode the client requires, perhaps on a different target. When the code is running, we may need to capture signal traces to diagnose the fault. When we have the fault, we might need to change the code or the hardware, or both, for the client feature to work. This role requires a practical, hands-on approach. Candidates are expected to actively write, debug, and test code, work directly with hardware, and spend time investigating issues in depth. Applicants who are not prepared to engage directly with low-level code, testing, and debugging, or who rely primarily on automated tools without deeper understanding, are unlikely to find this role suitable. Please note this role is not to develop hardware. Clients supply us boards to bring up. If you want to design PCBs from scratch, this is not the job for you. If you enjoy bringing up software stacks on new hardware, this is the job for you! Any knowledge of embedded OS is an advantage (FreeRTOS, Zephyr, Linux/Android, ThreadX). Ability with a soldering iron is useful. Familiarity with automated testing is useful but not required (e.g. hardware-in-the-loop). If you thrive in responsive, hands-on work and enjoy solving difficult problems efficiently, this could be the right role for you! Candidates must already have unrestricted permission to work in the UK. We CANNOT provide visa sponsorship, cannot extend visas, and cannot consider candidates whose right to work is time-limited or dependent on future sponsorship, including Graduate visas. Please do not apply if you require visa sponsorship now or at any point in the future. Candidates must know embedded C programming and any one of the following: • Embedded Linux e.g. Yocto or Buildroot build system, • Python, • Android build system, • Networking and communication protocols, • Embedded OS use, • Power optimisation, • Makefiles / build configuration systems, • Basic soldering, • Unit testing 40 hours of full time effort are expected every week. Remote working is offered, although 2 days per week on site are required. Flexitime is offered as standard, although all hours must be accountable. 25 days' vacation are offered, growing with tenure. Job Types: Full-time, Permanent Pay (Based on experience): £40,00.00 - £55,000.00 per year Benefits: • Flexitime, • Sick pay, • Work from home Schedule: • 8 hour shift, • Flexitime, • Overtime Education: • Diploma of Higher Education (preferred) Experience: • C Programming: 1 year (preferred), • Software engineering: 1 year (required) Right to work in the UK – important reminder: • Applications from candidates who do not already have unrestricted UK work authorisation will not be considered., • Work Location: Hybrid remote in London SE1 with 2 days per week on site near London Bridge.

🚀 Product Engineer – High-Impact Software, Real Ownership Extremely competitive salary (6 figures+) and package to be discussed IF this role is suited to you! This isn’t a typical software engineering role. I’m working with a product-led software company whose platform is used globally by highly technical users to solve real, complex problems in web technology. They’re looking for Product Engineers who care deeply about outcomes over output - engineers who want genuine ownership, autonomy, and the chance to build software that truly matters. This role is perfect for engineers who started as Java developers but have grown to work across multiple languages, frameworks, and stacks. If you like solving problems, shaping products, and exploring new technologies, this role is for you. This is a role for thoughtful engineers who want to shape what gets built, not just how it’s built. What makes this role different? You won’t be handed a backlog and told to crack on. From day one, you’ll: • Own problems end-to-end, • Talk directly to users and use insight to guide decisions, • Design, build, and evolve features used by a large, expert audience, • Be trusted to experiment, iterate, and make sensible trade-offs, • Ship meaningful work with real-world impact It’s high-leverage work in a high-trust environment. 🛠 What you’ll be doing • Solving complex technical problems with creativity and sound judgment, • Working across the stack as an expert generalist (backend-leaning, but curious everywhere), • Designing and shipping robust, user-ready features, • Collaborating closely with other engineers, designers, and product partners, • Sharing work early and actively inviting feedback, • Using modern AI tools (LLMs, copilots, agents) to improve developer workflows and explore user-facing product opportunities 👀 What they’re looking for This role suits engineers who are product-minded problem solvers, not just implementers. You’ll likely bring: • Strong backend engineering experience (Java is ideal, but mindset matters more than language), • Comfort working across different technologies (e.g. Java, .NET, Python, Go, microservices), • Experience in product-led teams, • Confidence operating in ambiguity and owning problems through to impact, • A genuine interest in users, not just systems, • Curiosity about AI — and good judgment about when (and when not) to use it Just as important as technical skill: • Growth mindset, • Openness to feedback, • Strong collaboration habits, • High personal standards for quality and clarity Both technical excellence and cultural fit are critical — the bar is deliberately high. Why consider this role? • Software with genuine purpose and global reach, • Real ownership and influence over product direction, • A culture of autonomy, trust, and continuous learning, • High standards paired with strong support, • Excellent compensation based on individual impact, • A collaborative, humble, and high-performing engineering team If you’re a backend-leaning engineer who enjoys thinking deeply, building carefully, and working on problems that actually matter, this is well worth a conversation.

This is a backend-leaning role (circa 80% backend) where you will own core systems end to end, shaping APIs, designing data models, and shipping production code used by real users from day one. You won’t be handed Jira tickets and told what to build. Instead, you’ll work directly with the CTO, making architectural decisions. This is a contract role for someone who thrives in ambiguity, enjoys high ownership, and wants to make a visible impact quickly, without the drag of corporate process.

The goal is simple: launch high-quality ventures dramatically faster than traditional startups. You’ll gain exposure, ownership, and shipping velocity that would usually take years to accumulate, all compressed into a contract where your work directly shapes real products in the wild. Employee Benefits • £400 per day contract rate, • Outside IR35, • Upskilling allowance, • Access to best-in-class AI development tools, • High-autonomy, low-ego engineering environment, • London-based, with flexibility for the right contractor Python Developer | Python & FastAPI | Founding Engineer in High-Growth AI Venture Studio Contract | £400/day | Outside IR35
