Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Founding Engineer - **Company:** SR2 - **Location:** London, UK - **Salary:** £115,000.0 - **Contract:** Permanent contract - **Skills:** Application Programming Interfaces (APIs), Artificial Intelligence, Microsoft Azure, Continuous Integration, Data Architecture, Python (Programming Language), PostgreSQL, Software Engineering, TypeScript, ReactJS, Large Language Models, Backend, Fastapi, Event Driven Architecture, Domain Driven Design - **Published:** September 10, 2026 - **Apply:** https://www.collegerecruiter.com/job/2858100908-founding-engineer ## About the Role * Roughly 1-5 years of commercial engineering experience * Strong software engineering and architectural fundamentals * Experience building LLM/AI functionality in production, rather than purely personal experimentation * Evidence you've thrived in an early-stage environment or another high-calibre engineering team * A product mindset and willingness to work across the stack * High ownership, curiosity and comfort operating without everything being predefined Experience with clean architecture, domain-driven design and event-driven systems would be particularly useful. ## Description The product is already live, paid for and being used daily, so this isn't an AI idea waiting around for a use case. The next phase is about taking something that's working, scaling the platform and expanding into new markets., You'll join a team of around 10 as a Founding Engineer, working closely with the founders and taking genuine ownership across product and engineering. You'll be: * Building production-grade agentic AI workflows and LLM-powered product features * Owning backend development using Python and FastAPI * Designing APIs, services and data architecture using PostgreSQL * Working across architecture, infrastructure, CI/CD and Azure * Contributing across React/TypeScript where needed * Working directly with users to understand messy real-world problems and turn them into simple products * Influencing technical architecture, product direction and engineering standards as the company grows There won't always be a perfectly written ticket waiting for you. A big part of the job is working out what should actually be built, then making it happen. ## Related Videos - [You are not an AI developer](https://www.wearedevelopers.com/videos/1148-you-are-not-an-ai-developer) - [Intro to FastAPI](https://www.wearedevelopers.com/videos/462-intro-to-fastapi) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Azure AI Foundry for Developers: Open Tools, Scalable Agents, Real Impact](https://www.wearedevelopers.com/videos/1541-azure-ai-foundry-for-developers-open-tools-scalable-agents-real-impact) ## Related Articles - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
