Senior AI Engineer

You will:

• Own the system, infrastructure, and agents behind a new product area from first version to scaled operation
• Build agent-driven workflows where agents write code, review code, debug failures, analyze data, and support operational reliability
• Design the agent factory itself: workflows, skills, hooks, guardrails, review loops, and escalation paths
• Make pragmatic technical decisions that directly shape product quality, speed, and revenue impact
• Build robust backend systems around messy real-world inputs, changing requirements, and operational complexity
• Create the internal tooling and control surfaces needed to operate the system with confidence
• Work closely with the founders and the wider team to turn a strategic direction into a real product
• Push forward how software engineering works in practice when agents become part of the core development loop

What We’re Looking For

We’re looking for someone senior, highly autonomous, and unusually strong at turning ambiguity into working systems.

You likely have:

• Significant experience as a software engineer in a startup or similarly high-ownership environment
• A strong track record of owning systems or products end-to-end, not just contributing to one part of them
• Deep hands-on experience with agent-driven development or coding-agent workflows
• Strong backend engineering skills and good judgment around scalable, reliable systems
• Experience building around brittle external dependencies, automation, scraping, data pipelines, or operational workflows
• Excellent taste and technical judgment — you know when something is robust, when it is fragile, and when agent-generated output is just slop
• High agency, strong prioritization skills, and the ability to operate with very little structure
• An ex-founder mentality or the mindset of an early engineer who likes real ownership and responsibility
• A desire to build something strategically important and make decisions that matter

This role is a strong fit for people who have been:

• founders
• very early startup engineers
• senior builders who have owned messy systems with real business impact
