Re-posted 16 days ago
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 a Founding 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 OnSearch 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
You don't need to fit neatly into one area — most people here won't.
Application Engineer (Full-Stack)
Build fast, expressive interfaces across mobile and web
Own features end-to-end from UI to backend
Tools: TypeScript, React, React Native, iOS/Android
Data / AI Engineer
Build the intelligence layer — search, ranking, pipelines, and agent systems
Design systems that operate over large-scale, messy real-world data
Tools: Python, TypeScript, Elasticsearch, Snowflake, LLMs, embeddings, retrieval and recommendation systems
0–5 years of professional software engineering experience
Proven experience building real-time or low-latency production systems
Proficiency in search, ranking algorithms, and related infrastructure
Experience with data processing pipelines, ML/AI workflows, or data engineering
Track record of infrastructure and performance optimization at scale
Prior experience at early-stage startups; comfortable operating with high ambiguity
Ability to own features end-to-end with cross-functional collaboration (product, design, engineering)
Strong problem-solving and fast decision-making in fast-paced environments
You care about how something feels, not just whether it works
Salary: $150,000 – $250,000 USD annually
