Founding Product Engineer

About this role

VOYGR (YC W26) | Founding Product Engineer | San Francisco | ONSITE | Full-time | $150K-$200K + 0.5%-2.0% equityI'm Yarik, cofounder and CTO. Before this I spent 20 years in tech with 10+ years running infra, ML and search teams at Google, Meta and Apple.
We love maps and build location/businesses APIs for AI apps and agents. If ChatGPT tells you a restaurant is open and it actually closed in March, that's the problem we fix. We check whether a business still exists, whether its hours and details are right, and enrich it with what's being written about it on the web (news, articles, events). Customers get all of it through one API and we solve it for them with our models which use all available sources and ai voice agents which can confirm the information.
You'd be one of the first engineers. Some weeks that's search and ranking, some weeks it's data pipelines or evals, some weeks it's the API or something a customer asked for yesterday. You'll have a big say in what gets built, not just how.
Stack: Python, FastAPI, Postgres/PostGIS, DynamoDB, Redis, AWS (EKS), our own ML models plus LLM APIs (OpenAI, Gemini, Anthropic).
What I'm looking for:
- 2+ years shipping production…
