Software Engineer (Backend/AI Infrastructure)

We are looking for Software Engineers to join our partner company!

You will play a key role in building next-generation infrastructure and AI systems that accelerate innovation across industries such as aerospace, healthcare, and energy — fields still limited by outdated, manual processes.

This is not a traditional engineering role. It’s a chance to join an early-stage, high-impact environment where every line of code shapes how ideas become reality. Backed by top-tier global investors, our partner company is scaling fast and looking for exceptional builders who thrive on ownership, speed, and purpose.

What You’ll Do

• Design and develop production-grade APIs, distributed systems, and backend services using Python, TypeScript, Go, Rust, or similar technologies.
• Design and ship backend systems from day one — scalable architectures, APIs, and AI-powered tools.
• Build and deploy LLM-based applications using frameworks such as LangChain, semantic search, RAG, and fine-tuning (SFT/RL).
• Develop backend logic and data pipelines to power intelligent automation and real-time processing.
• Manage infrastructure: relational and graph databases, containerization, CI/CD pipelines, and cloud platforms (AWS + Pulumi preferred).
• Write clean, efficient, and maintainable code with a focus on performance, reliability, and scalability.
• Collaborate across technical and product teams to solve complex engineering challenges.
• Contribute to a culture of execution, ownership, and learning, where speed and quality go hand in hand.

Who You Are

• Minimum 2 years of professional experience as a Software, Backend, or AI Engineer.
• Proven track record of building and shipping production-ready systems.
• Hands-on experience with distributed systems, APIs, databases, and cloud infrastructure.
• Familiarity with LLMs, LangChain, RAG, or fine-tuning techniques (SFT/RL).
• Strong problem-solving and debugging abilities with a proactive, builder’s mindset.
• Comfortable in a fast-paced, early-stage environment where you take ownership from day one.

What’s In It For You

• A mission-driven environment in London, working hands-on to build technology that matters.
• Competitive compensation + meaningful equity.
• Visa sponsorship, relocation assistance, team meals, and all tools needed to move fast.
• A collaborative culture built on trust, focus, and shared ambition.
