Founding Engineer

About the Role

Join a well-funded (Series A/B), stealth-stage consumer tech startup building an AI-powered map and social discovery platform. The product helps people figure out where to go and what to do — combining one of the largest structured indices of real-world places and events with a clever, social product experience.

As aFounding Engineer, you'll own problems end-to-end, work directly with founders, and make architectural decisions that shape the core system. This is a high-ownership, high-impact role for someone who thrives in ambiguity and moves fast.

What You'll Work On

• Search and ranking at massive scale (200M+ places, millions of events)

• Recommendations and personalization of places and events using embeddings, structured data, and social signals

• Real-time infrastructure — chat, presence, and location systems that feel instantaneous

• AI agent pipelines that plan, retrieve, and reason over diverse data sources

• Map display algorithms that determine what deserves attention

• Data pipelines that structure large volumes of unstructured web data for novel product experiences

• Pushing Elasticsearch and vector search to sub-100ms latency across large datasets
