About the company
Our client is an early-stage software company.
The role
Raydar is recruiting for this role on behalf of our client. Join as the first engineer and take broad ownership of product and technical direction, working across the full stack. You will build and run reliable production systems, develop AI-driven features and work closely with customers to turn their needs into shipped software.
What you'll do

- Experience building AI agents or agent-based systems, including LLM API use in production.
- High agency, resilience through shifting priorities, and comfort wearing multiple hats.
- Ability to prioritize at a granular level without close management.
- Willingness to work in person.
Bonus points
- Experience with Postgres, Redis, queues and asynchronous job systems.
- Background in browser automation, scraping or retrieval infrastructure.
- Experience with agent context management, orchestration and evaluation.
- Experience with developer tools or workflow products.
- Exposure to ecommerce, search, attribution or analytics systems.
