Staff Software Engineer - AI Apps

• Founding-team Staff Engineer role at a well-funded stealth AI company
• Product: AI-native productivity - starting with email, expanding into notes, tasks, calendar
• Own the full engineering layer: backend systems, APIs, and client applications
• The hard part isn’t the AI - it’s making it reliable at scale
• US$100M initial funding, internally backed, no VC pressure
• Cash + meaningful founding-team equity
• Fully remote

• Significant experience leading application or product engineering for complex, production systems
• Strong backend engineering fundamentals - you’ve built and shipped systems people actually use
• Experience building the systems around AI - orchestration, tool use, state, retries, and failure handling - not just calling an API and rendering the output
• Comfortable across backend and client platforms, with deep expertise in at least one
• Strong technical judgement - you make good calls with incomplete information and own the outcome
• Zero-to-one experience - you know what pre-launch engineering actually feels like

Who this isn’t for

Engineers who want to manage tickets and attend standups. People whose AI experience begins and ends with wrapping a ChatGPT endpoint. If your production systems don’t exist outside of a demo, this isn’t the role.

The rest

Everything else - who they are, who’s behind it, comp and equity detail - is a call.
