Your decisions about agent architecture, provider selection, and quality assurance directly determine whether our companies’ AI delivers in production. This is a software engineering role with an agent specialisation. You’re a full-stack engineer first - you write backend services, build APIs, and ship features end-to-end.

The integration layer that makes agents useful in real businesses., • Full-Stack Delivery: You write backend services, build API endpoints, and contribute to the frontend when needed. Agents don’t exist in a vacuum - this is still a software engineering role., • Product Direction: You work closely with the founding team to translate cohort feedback and client needs into agent architecture decisions. What to build matters as much as how you build it. What We’re Looking For • Strong software engineer first. You write clean, production-quality code and you ship fast. Real deployed systems, not notebooks., • Experience building with closed-source model providers in production - shipping agent workflows to real users, not just prototyping., • Practical understanding of prompt engineering, tool use, and agent evaluation. You know what makes an agent reliable versus what makes a good demo., • Full-stack capable. Backend (Python), infrastructure basics, and enough frontend (React/TypeScript) to ship features end-to-end., • Fluent with modern AI tooling - you use Cursor, Claude Code, or similar daily and it makes you faster. AI tooling is not optional here., • Comfortable with ambiguity and startup pace. Priorities shift weekly based on cohort feedback., • Right to work in the UK permanently. We care less about • Your degree (or lack of one), • How many years you’ve been working - we care about what you’ve shipped, • Whether you’ve published papers - this is an engineering role, not a research role Tech Stack • Backend & Agents: Python, pydantic-ai, proprietary agent frameworks, OpenRouter, • Frontend: TypeScript, React, Vite, • Infrastructure: AWS (EKS), Docker, Inngest (event-driven orchestration), • Tools: Cursor, Claude Code, GitHub Why Join • Ownership. Significant equity as a founding engineer. The agents you build power every business on the platform., • Real traction. Paying customers, founding cohort live, and a significant raise in preparation. What you build in the next 6–12 months directly determines whether we hit 10 companies by September., • Exceptional team. Co-founder who sold his AI company to WPP for $100M. Product leader who scaled a Meta platform to 400K+ users. Research team published at top AI venues with work adopted by leading universities and Fortune 500 R&D teams. Advisors include a leading NLP researcher and a Google DeepMind team lead., • Flexibility. Fully remote, UK timezone. Regular offsites. We care about what you ship, not when you’re online.

Product Engineer (Backend) — 0 to 1 builder wanted Are you a backend engineer who thinks in systems, owns their decisions, and has the scars to prove it? Have you built something from scratch — as a founder, a founding engineer, or one of the first people in the door at a startup that actually shipped? A high-growth product team inside a fast-moving fintech is looking for a Backend Product Engineer to help build a new product line from the ground up. This team moves like a startup — lean, fast, and focused on getting things into users' hands. They're language-agnostic, but think primarily in Go. More importantly, they think in outcomes. What you'll do ▸ Architect and build the core — own the backend systems, APIs, and infrastructure that power a new product line. No one will hand you the design. ▸ Ship fast, then make it right — MVPs in weeks, not quarters. They need someone who can make good trade-off decisions quickly and iterate without fear. ▸ Influence the product — they want engineers who push back, ask why, and bring their own perspective on what should be built and how. ▸ Take full ownership — from design through deployment. This team has no room for ticket-takers. The team This is a moonshot team — operating separately from the company's day-to-day, with the mandate to build something genuinely new. The successful candidate reports directly to the head of the organisation. No bureaucracy. No waiting for committee sign-off. Strong people, hard problems, fast pace. The role is in-office in London, 5 days a week. This team works hard — realistically 50–60 hours a week. They're looking for someone who is genuinely ambitious and wants to build something they're proud of. What they're looking for ✓ Ex-founder, co-founder, or first-10 engineer at a startup — this is non-negotiable.

C++ Software Engineer Location: Surbiton Hybrid: You'd be expected in the office at least once as week Skills: C++, Git, Linux, Atlassian (Jira / Bitbucket) If you're a C++ Software Engineer who gets restless without a hard problem to solve, keep reading. We're working with an established software company operating in a specialist niche, the kind of place where the engineering matters, the codebase is taken seriously, and nobody's reinventing the wheel for the sake of a conference talk. They're hiring two C++ Software Engineers to strengthen an already capable team, and they're open on level, graduate through to mid/senior. What this actually is This is server-side, backend, production C++. You'll be writing and maintaining modern C++ code on systems where performance and correctness aren't nice-to-haves, they're the job. You'll own complex development work, push engineering standards forward, and work alongside Senior Developers who have real depth. It's an R&D-flavoured environment. That means curiosity is valued more than confidence, and "I want to understand how this works" will take you further here than "I've done this before." The team is also honest about the future: C++ is the foundation, but there's genuine scope to grow into Rust and Go over time if that's where your interests take you. You're the right C++ Software Engineer if you have • Commercial C++ experience in a production environment: you know what it means to ship code that can't fall over, • Linux or Windows experience (ideally both, but either works), • Strong debugging instincts and an engineering mindset built around quality and performance, • Genuine curiosity; this role suits someone who reads beyond the ticket, • Bonus (genuinely optional) for exposure to Rust or Go. The package • £35,000–£65,000 depending on level, • 15%+ performance bonus, • Profit share bonus, • Up to 10% pension, • Hybrid working: more flexibility extended to more senior C++ Engineers Worth knowing Interviews are moving fast. Two roles means two chances, but the pipeline won't wait. Sponsorship is not available for this role. Interested in this C++ Software Engineer opportunity in Sunbury-on-Thames?

Quant Developer - Rust/Java/C++ - London - £130k base (minimum) + bonus Who? One of the world's leading macro hedge funds ($30bn+ AUM) with a dedicated digital assets division. Small Product Engineering team (13-14 engineers) sitting between core systems and trading desks. Tech? Rust (primary language from day one). If you're currently in Java, C++, or C#, you'll transition to Rust immediately. Strong fundamentals matter more than prior Rust experience (memory management, garbage collection, algorithms, systems concepts). Python is a plus, but insufficient alone. What? Build critical trading infrastructure in Rust (no prior exp needed). You'll own the data layer between core systems and digital PM teams (real-time market data ingestion, position consolidation, and exchange connectivity). Front-to-back visibility across the front/mid/back office, without sitting at a trading desk. Pure engineering, not quant analysis. Why? Portfolio Managers, Risk, and Treasury rely daily on the production-critical infrastructure that you'll be building. Ingest real-time market data via exchange APIs, consolidate positions and pricing across multiple sources, and deliver clean data pipelines to the business. The kind of work where downtime matters. Where? London, 3 days in office (likely moving to 5). WFH Monday & Friday for now. Requirements: • 2+ years as a backend/systems engineer (in finance, preferably), • 3+ years in Java, C++, or C# (Rust preferred but not required), • Computer Science bachelor's preferred, • Solid understanding of memory management, algorithms, and systems fundamentals We encourage you to apply even if you don't tick every box (proven academics, willingness to learn, and genuine intellectual curiosity count for a lot here).

Frontend Engineer (Fullstack) — UI-first, but you don't stop there! Are you a frontend engineer who thinks in components and in systems? Do you obsess over the user experience, but feel just as at home designing an API or wrestling with a data model when the product demands it? Have you got the battle scars of building something from scratch, whether as a founder, a founding engineer, or the first person in the room when the codebase was blank? A high-growth product team inside a fast-moving fintech is looking for a Frontend-strong Product Engineer to own the user-facing side of a new product line and everything behind it when needed. This team operates like a startup within a company. So lean, fast, and building MVPs that matter. The other two engineers on the team live in the backend. You're the one who makes the product feel real. They won't hand you a spec. They'll expect you to help write it. What you'll do ▸ Own the product experience: you're the person asking "but what does the user actually see?" in every technical discussion, and then building the answer. Frontend-first thinking, fullstack execution when it counts. ▸ Build fast and iterate: MVPs in weeks, not quarters. This team expects you to move quickly and make good decisions under ambiguity. ▸ Shape the product direction: they don't want someone who just builds what they're told. They want someone who challenges, scopes, and argues for the right thing to build. ▸ Go fullstack when the product needs it: you're not a UI-only person. You'll write APIs, dig into data models, and get into infrastructure when the situation calls for it. You just naturally start from the user and work inward. The team This is a moonshot team. A small group operating separately from the day-to-day, with the remit and the freedom to build something genuinely new. The successful candidate will report directly to the head of the organisation. No committee, no lengthy approval chain. Just strong people solving hard problems fast. The role is in-office in London, 5 days a week. This team works hard so if you want a 9-to-5, this isn't it. If you want to build something you're proud of, it might be exactly right. What they're looking for 🏗️ Ex-founder, co-founder, or first-10 engineer at a startup — this is non-negotiable. They need people who know what it feels like to own something. 🎨 Frontend-strong, with genuine fullstack capability. You're at your best in the UI layer, but you're not precious about it. Backends, APIs, data models, you can get there when you need to. ⏱️ 5+ years of strong engineering experience, with evidence of shipping things people use and love. 💬 Opinionated about product and able to explain not just what was built, but why, and that reasoning holds up under pressure. 🤖 Uses AI dev tools daily and can articulate specifically how it changes their output 📈 Ambitious, so you are someone who wants to see their work move metrics, not sit in a backlog. What they offer 💰 £100,000 – £150,000 base salary 🤝 Meaningful equity, a genuine stake in what you're building 🏦 Pension contributions 🎯 Direct access to leadership and genuine influence on the product from day one 🚀 The chance to build something from zero in a high-growth fintech with the resources to back it
