The role

The founding senior engineer is in the ultimate cross-sectional position, and will be involved in solving tough algorithmic problems, managing the entire tech stack, and building products end-to-end.

This will include building highly performant desktop applications (both the frontend and backend), as well as doing work on algorithmic development, and working closely with others on the team, especially AI engineers.

The role the founding engineer plays is limited only by their ability and ambition. The successful candidate must be an especially fast learner and problem solver with the ability to recognise and solve (or learn to solve) almost any problem that may arise.

You’ll love this role if you enjoy…

• Identifying and solving very challenging technical and research-level problems
• Building products end-to-end (from algorithm development, experimentation, all the way to UI/UX)
• Learning and keeping abreast of current research and developments related to LLMs/NLP, vision, and more
• Helping identify and tackle any technical challenge that may emerge
• Pushing beyond your comfort zone and maximise your potential

Requirements and experience

• 5+ years of experience working on similar projects
• Strong programming skills, ideally in Typescript, Python, and/or Rust/C++.
• A strong track record of solving difficult problems in either an academic or industrial setting
• A strong track record displaying the ability to manage engineering workflows (e.g. building robust and scalable products, working with users requests, etc.) and ideally also managing scientific processes (e.g. forming and testing hypotheses)
• Experience working with cloud infrastructure providers and database technologies (e.g. SQL/no-SQL)
• Ability to self-organise and work independently
• Based in, or willing to relocate to London (we are open to sponsoring visas)

Nice to haves

• Experience working with NLP/LLMs or other AI/ML
• ML/statistics/mathematics background or experience
• Experience working on open-source projects, working on an interesting side project, or contributing to Stack Exchange (or similar)
