About the role
- Design, build, and operate services that power retrieval, semantic search, agent orchestration, model integrations, and data pipelines that turn our proprietary signals into product features.
- Work with one of the deepest private-market datasets in the world and build systems that surface high-value signals for investors.
- Design and operate OpenSearch-backed retrieval and semantic search systems and tune them for real product use.
- Build and run agent orchestration, model integrations, and safety layers for LLM-driven workflows.
- Prototype new AI-driven features and productionize them in a Go-first codebase.
- Own large features end-to-end and improve our testing, observability, and operational practices.
Requirements
- A full-stack generalist or backend specialist who can work across the stack, with at least 4+ years of experience building large-scale web applications or backend services.
- Comfortable writing clean, production-quality Go (Golang) code, including services, libraries, and tests. Our repo is Go-first and includes modern Go AI and search libraries.
- Experienced in production search systems such as OpenSearch, Elasticsearch, or comparable platforms, with a track record of designing mappings and tuning queries for real traffic.
- Excited about LLMs, agents, embeddings, and retrieval, and able to turn prototypes into reliable, instrumented services. Experience with working with LLM APIs, tokenizers, or cloud GenAI SDKs is a plus.
- Comfortable with and curious about working outside of a traditional, narrow engineering role.
- A self-starter: you have started something meaningful on your own – a startup, an open-source project, or something else to share with us!
