Job summary

Ahoy is seeking a Fullstack Engineer in Dublin, available at Senior or Staff level, with hybrid work and in-person days. You will own features end to end— from ingestion and data modeling to API and customer-facing surfaces— and collaborate with founders on the product roadmap.

You’ll combine strong TypeScript/React with Python, work on distributed systems, API design, and build interfaces that people trust. Production ownership and on-call duties are expected.

Qualifications

• Strong experience shipping fullstack features across the stack.
• Deep TypeScript/React and Python expertise.
• Excellence in API design and data modeling.
• Experience with production systems and on-call duties.
• Hybrid work arrangement with in-person days in Dublin.

Responsibilities

• Ship whole features - the ingestion path, the data model, the API, and the surface a customer touches.
• Build the capture path - email, calendar, calls - and the pipeline that turns raw activity into records people trust.
• Build the surfaces where agent work becomes visible - review queues, one-tap approval, the diff between what the CRM knew and what it knows now.
• Work on how agents reason over CRM data: retrieval, tool use, evals, and the guardrails that keep a human in the loop.
• Own production. Instrumentation, on-call, and cost and latency budgets that hold under load.
• Pair with the founders on what to build next. Argue when something doesn't make sense.
