Founding Engineer

We are looking for a Founding Engineer to join our partner company! You will play a key role in building the next generation of infrastructure that powers real-world innovation across industries such as aerospace, healthcare, and energy — industries still slowed down by outdated, manual systems. This is a rare opportunity to help define how humanity brings new ideas into the physical world, working in a fast-paced, high-impact environment backed by leading global investors. Key Responsibilities Design, develop, and deploy multimodal foundation model-based products using LLMs and advanced AI tools. Apply your knowledge of LangChain, semantic search, RAG, and LLM fine-tuning (SFT/RL) to create scalable, intelligent systems. Architect and maintain infrastructure, including relational and graph databases, containerized services, and cloud platforms. Take ownership of the entire development lifecycle — from defining specs to shipping features and deploying to production. Collaborate closely with other engineers and founders to solve complex problems across infrastructure, product, and operations. Contribute to building a culture of speed, ownership, and innovation. Qualifications Minimum 2 years of professional experience as a software or AI engineer. Proven track record of delivering fast, production-grade code. Hands-on experience with large language models, agents, and multimodal systems. Proficiency with frameworks like LangChain and tools for indexing, RAG, and fine-tuning. Strong understanding of databases, containerization, and cloud infrastructure Bonus: experience founding or joining an early-stage startup. A high-intensity, mission-driven environment in London, working together 6 days a week. Visa sponsorship, relocation assistance, team meals, and all tools to move fast.
