The role
This isn’t another AI startup building a chatbot. This company acquires profitable, mission‑critical B2B SaaS businesses, then deploys a proprietary AI operating system across them. The system ingests vast amounts of operational data – from CRM to financial records – to encode best practices and layer autonomous agents on top, automating sales, onboarding, and customer success workflows. They’re well‑funded by leading investors, with a founding team from top‑tier engineering and frontier AI research backgrounds. You’ll join a small, rapidly scaling engineering team (currently four, growing to ten) and own the hardest end‑to‑end problems on the core platform. This is a Staff Software Engineer role focused purely on technical leadership and deep problem‑solving, not people management. You’ll design the architecture for a system that scales across dozens of diverse businesses, working directly with the CTO and Engineering Lead to set technical direction. This seat is for a force multiplier who raises the bar through code and mentorship, not someone looking to manage a team.
The work
- Architect and build core components of a proprietary AI operating system, scaling it across a portfolio of B2B SaaS companies.
- Own end‑to‑end delivery of complex features, from deep data integration to autonomous agent deployment.
- Define technical strategy and make critical trade‑off decisions that shape the platform’s evolution and scalability.
- Anchor critical workstreams, solving open‑ended problems around heterogeneous data, operational knowledge encoding, and autonomous action.
- Raise the engineering bar across a small, fast‑moving team through code review, mentorship, and technical leadership.
What You Bring
- 5+ years shipping production systems end‑to‑end, with clear examples of architectural decisions that drove business impact.
- Deep expertise in at least one modern stack (e.g., Python, Ruby, Go, Java) and the ability to quickly master new languages.
- Proven track record as a technical force multiplier on small, fast‑moving teams: setting the bar, mentoring, and accelerating peers.
- Exceptional ability to break down ambiguous problems, prioritize high‑leverage work, and communicate complex trade‑offs to both technical and non‑technical stakeholders.
- Based in London or willing to relocate.
