We’re looking for a Lead AI Software Engineer to help shape and scale our AI capabilities. This is a hands-on, Python-heavy role for someone who enjoys writing production-quality code and building AI-powered systems end to end.

You’ll spend a significant portion of your time developing in Python—designing, building, and shipping AI and data-driven features—while also providing technical leadership and setting direction for how AI is used across the business. You’ll work closely with product, engineering, and data teams to take ideas from prototype to production in a fast-moving startup environment.

This role is ideal for someone with strong software engineering fundamentals, deep interest in AI, and a bias toward action and ownership.

What you’ll do
  • Design, build, and deploy AI-driven features and systems in Python
  • Take prototypes and research ideas through to scalable, production-ready applications
  • Improve platform performance, data models, and developer experience
  • Provide technical leadership and mentor engineers across the team
  • Act as an internal AI expert, advising teams on effective use of LLMs and emerging AI tools
What we’re looking for
  • Strong Python development experience and a track record of writing clean, well-tested code
  • Experience running AI systems in production and turning new ideas into real products
  • Cloud experience building scalable AI and data applications
  • Comfort working end to end, from architecture to delivery
  • Clear communicator who thrives in collaborative, fast-paced teams
Nice to have
  • Experience with generative AI frameworks and evaluation strategies
  • Familiarity with modern data stacks and cloud AI platforms
  • Front-end experience (React / JavaScript)
  • Experience with CI/CD, infrastructure-as-code, and modern DevOps practices
