Job description

Have you worked as a software engineer at a Big Tech or similar company, developing cutting-edge technology platforms that integrate ML based automation with world-class software engineering? Have you worked on difficult problems and revel in the development of innovative solutions? Can you work with abstract computer science notions and turn them into production code?This London based start-up is looking to disrupt and revolutionise their target business markets through their ML based technology. Their solutions look to improve business productivity through technology-based efficiency and optimisation, via autonomous development by their in-house built AI-powered platform. They have secured VC funding for growth and are looking to double their engineering team within the next 12 months.Requirements:

• You’ll be smart – likely studied computer science or similar at a top 50 world ranked university and possibly a PhD; or studied a STEM degree at Cambridge, Oxford, Imperial or similar and pivoted into software engineering.
• You’ll have worked as a software engineer at a Big Tech or similar company and have demonstrable experience working on autonomous software platforms involving a complicated and sophisticated codebase.
• Ideally you will have professional experience working with LLMs, manipulating them to develop robust products. Otherwise, you will be a keen experimenter with LLMs, utilising the skills and knowledge you have in software engineering for LLM based personal projects. Key topics of interest would be agentic systems, RAG, Langchain or automated workflows.
• You’ll have experience using modern Python for scalable and extendible code development (and probably experience with other modern mainstream coding technologies such as Go or Rust).

What you have done so far is important as the company want to see your demonstrable experience. Currently, they are not looking to sponsor candidates for work permits; interested applicants must have full rights to work in the UK. Offices are based in central London, but hybrid working is an option (2-3 days in the office per fortnight).
