Senior Engineer.

Dublin · Full-time · Hybrid

Senior IC on the founding engineering team. You ship full features end-to-end — backend, AI agents, frontend, demos — and you pair with founders on the things customers will see next week. We hire across the stack and we expect you to be comfortable owning a slice of it.

What you'll do

Build customer-facing features end-to-end: API surface, agent behaviour, UI, and the polish that makes them feel built-in.
Own production systems you ship — instrumentation, on-call, the bug that surfaces a week later.
Pair with the founders on what to build next. Argue when something doesn't make sense.
Help design how the agents reason about CRM data and how that reasoning surfaces in the product.
Set technical patterns for the rest of the team to follow.

What you bring

5+ years shipping production software — ideally Python on the backend and TypeScript / React on the frontend.
Strong fundamentals: databases, distributed systems, API design, async work.
Comfortable across the stack. You can move from a schema migration to a UI bug to a prompt tweak in the same day.
You write code you're proud of, you ship it, and you delete it when it stops earning its keep.
Hybrid out of Dublin. We work in person several days a week.

Bonus

You've built with LLMs or agent frameworks in production (retrieval, tool-use, evals).
You've worked on CRM, sales tech, or pipeline software before.
Open-source work, side projects, or writing that shows how you think.

How to apply

Email [email protected] with a short note: who you are, what you've shipped, and links to anything you'd want us to see. Code or product is louder than résumés. We read every message.
