• Build production-grade systems with Python and LLM integrations
• Turn real customer problems into scalable technical solutions
• Work closely with product, operations, and customers
• Contribute to architecture decisions and engineering standards
• Help shape team culture and ways of working as an early engineer

What We’re Looking For

• Senior-level software engineer (founding / early-stage experience is a big plus)
• Hands‑on experience integrating LLMs into real products
• Strong backend experience (Python preferred)
• Comfortable working directly with customers
• High ownership, independence, and maturity

Location

• On-site in London, 5 days per week (mandatory)
