To join our partner company, we are seeking Software Engineers!

You will be crucial to the development of AI systems and next-generation infrastructure that spur innovation in sectors like energy, aerospace, and healthcare, which are currently constrained by antiquated manual procedures.

This is not a typical engineering position. It's an opportunity to work in a high-impact, early-stage setting where each line of code influences how concepts are realised. Our partner company, supported by elite international investors, is expanding quickly and seeking outstanding builders who are passionate about ownership, speed, and purpose.

What You'll Do

• Create and implement backend services, distributed systems, and production-grade APIs utilising Python, TypeScript, Go, Rust, or comparable technologies.
• Create and deliver backend systems with scalable architectures, AI-powered tools, and APIs right now.
• Use frameworks like LangChain, semantic search, RAG, and fine-tuning (SFT/RL) to develop and implement LLM-based applications.
• Create data pipelines and backend logic to enable intelligent automation and real-time processing.
• Oversee infrastructure, including cloud platforms (preferably AWS + Pulumi), containerisation, relational and graph databases, and CI/CD pipelines.
• Focus on performance, dependability, and scalability when writing clear, effective, and maintainable code.
• Work together across product and technical teams to resolve challenging engineering problems.
• Contribute to an execution, ownership, and learning culture where quality and speed go hand in hand.

Who You Are

• A minimum of two years of work experience as an AI, backend, or software engineer.
• A track record of successfully developing and delivering systems that are ready for production.
• Practical knowledge of databases, cloud architecture, distributed systems, and APIs.
• Knowledge of RAG, LangChain, LLMs, or fine-tuning methods (SFT/RL).
• Strong debugging and problem-solving skills combined with a proactive, builder's mindset.
• At ease in a fast-paced, early-stage setting where you assume responsibility right away.

What You Get Out of It

• Working directly to create technology that matters in a mission-driven setting in London.
• Competitive pay plus significant equity.
• Sponsorship of a visa, help with moving, team lunches, and all the equipment required to move quickly.
• A cooperative culture based on attention, trust, and common goals.
