Founding Engineer - £100k plus equity You're an engineer who gets bored when things move too slowly. You've spent time at places where "move fast" means shipping a few features a month, and you're done with that. You want to build something from scratch, make decisions that matter, and see your work in production within days, not quarters. This VC-backed startup is automating finance operations for modern companies, starting with accounts receivable—the messy, manual process of collecting revenue companies are already owed. The founders know what they're building, they know who needs it, and they need someone who can turn that clarity into code. What You'll Build Own the revenue engine. Build systems that parse usage-based contracts, automatically generate invoices from consumption data, and manage collections. Design APIs integrating with billing platforms, create LLM-powered contract interpretation, and build data pipelines handling complex signals. Shape the product from zero alongside the CTO. Drive architecture decisions, technology choices, and product direction. Your early decisions define how this company scales. You're the Right Fit If • 5+ years building and scaling systems at places that matter, • Full-stack with serious backend chops: TypeScript/JavaScript, Python, FastAPI, Next.js, PostgreSQL, ClickHouse, • Ready to ditch colleagues who think in terms of "that's not my job" - that doesn't exist here, • You care about product and design decisions, not just technical ones, • 0-to-1 thinking excites you more than optimizing existing code What's on Offer • ESOP Equity, • 25 paid holidays + public holidays, • Health and dental insurance, • £2k IT budget, • In-office role (London Bridge) with a great bunch of curious people If you're ready to build finance infrastructure that actually works, email with the title (Pivot Me) and a few lines about the products you have created.

Python Developer | Python & FastAPI | Founding Engineer in High-Growth AI Venture Studio Contract | £400/day | Outside IR35 The Role You’ll step in as a Founding Engineer within an early-stage AI venture studio that builds and launches creator-led B2C software businesses at speed. 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. What They’re Looking For (Non-Negotiables) Ideally, you’ve worked in B2C businesses or VC-backed startups where products scaled rapidly and engineering had to keep up. You naturally take responsibility, communicate clearly, and act with intent, with more founder mentality than feature factory. You’re comfortable building things that don’t yet have perfect answers. What You’ll Work With • Python development at a high level, • FastAPI or adjacent Python backend frameworks, • API design and backend architecture fundamentals, • PostgreSQL and/or MongoDB, • React or React Native for frontend collaboration, • AWS serverless infrastructure, • Docker for bespoke services Nice to Haves • B2C mobile or consumer product experience, • Experience in VC-backed or hyper-growth environments, • Node.js development alongside Python, • Vector databases such as Chroma and embedding pipelines, • LangChain, CrewAI, or similar AI orchestration frameworks, • Practical security and data privacy awareness, • Linear or similar planning tools, • Experience with image modelling AI systems, • AI-assisted development using tools such as Claude Code Why Join / Projects This venture studio partners directly with large creators (often with 1M+ followers) as co-founders, meaning every product launches with built-in distribution, immediate users, and fast feedback loops. Under the hood, you’ll be building on an internal AI-first factory made up of reusable components, agent-driven workflows, and a growing knowledge graph that improves with every product shipped. 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

🚀 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.
