Tired of how recruitment works? Come join us and do something about it.
We're turning Wave into the first AI-native tech recruitment business in the world - and we're looking for another engineer to help us build it.
The problem: every agency sits on relationships and information.
Almost none of them turn the information into an advantage.
We're building the layer that does: every candidate, company and conversation, captured and made useful.
That's Mothership, our internal data lake, copilot and dashboard product.
It already powers Wave Mind, our external product, which is live and revenue generating.
The gap we're hiring for: someone who can move between building the product surfaces people actually use (dashboards, copilot workflows) and hardening the data foundation underneath (pipelines, schema, data quality).
Roughly 50/50.
Who this is for:
4-6 years building and shipping software, ideally with a genuine product or front-end chapter before you moved into dataReal pipeline experience: monitoring, alerting, schema versioning, no silent failuresStrong Python and SQL; TypeScript/React is a bonusYou use Claude Code and AI tooling as a daily force multiplier, not a noveltyComfortable making architectural calls without a complete specYou want equity, real ownership and a seat on the roadmap, not a ticket queue
Our current stack:
Python, SQL, PostgreSQL, Supabase, GCP, and React/Next.js, Node.js/TypeScript on the product side.Bullhorn, Granola, Xero, Notion, Slack, Claude in the daily toolkit.
Why now: Our Wave Labs team is currently 7 people.
The foundation is built.
The product is proven in market.
This is the stage where the person who joins shapes what gets built next, not the stage where you inherit someone else's roadmap.
We're not competing with other agencies.
We're competing with funded agentic recruitment startups like Jack & Jill and Dex, who have the AI but none of the relationships or database.
We have all three and we're building the tech to match.
