Job Description
Founding Software Engineer – AI Infrastructure | DeepTech | On-site London | £100,000 – £180,000 + Equity
A well-funded, early-stage AI infrastructure startup is on a mission to remove one of the last major bottlenecks in the physical world. They’re building the core AI systems to power the next generation of real-world innovation.
They're looking for a high-ownership, deeply technical founding engineer to join their small, hands-on team. You'll ship fast, own features end-to-end, and help define both the product and the company from the ground up.
Responsibilities
- Ship production-grade code from day one
- Own full-stack feature development across infra, tooling, and application layers
- Solve hard technical and operational problems, scaling infra, fine-tuning models, jumping on customer calls, or hiring the next teammate
- Write specs, take initiative, and push through ambiguity with minimal guidance
- 2+ years of experience building and deploying real products
- Deep understanding of LLMs, multimodal models, agents, and tooling (e.g., LangChain, RAG, SFT/RL fine-tuning)
- Strong knowledge of infrastructure, including cloud platforms, containerization, relational/graph databases
- Track record of building quickly, independently, and to a high standard
- Bonus: Previous experience as a founder or early team member at a startup
- Salary: £100k – £180k depending on experience, with meaningful equity
- Location: On-site in London (visa sponsorship & relocation covered)
- Environment: High-trust, in-person collaboration, and a tight-knit team deeply motivated by the mission
- Extras: All tools, meals, and support needed to move fast and focus on what matters
If you're excited by the idea of building category-defining infrastructure at speed and want to work with a team that shares that urgency, please apply with your CV.
