About this role

The Opportunity

75% of the best candidates never apply to jobs. They're not looking. They're building.

We're building AI agents that do the actual work of recruiting: finding passive candidates, reaching out, qualifying, coaching, scheduling. End to end. No job boards. No applications. Direct connections between great people and great companies.

We raised a pre-seed from top investors and have been growing to marketplace scale (40K+ talents, hundreds of top startup customers). Now we need someone to help build the infrastructure that scales this 100x.

The Role

You'll work directly with our CTO Daniel and ship to production daily. This isn't ticket duty. You'll own entire systems and see them in the hands of users the same week.

Location: San Francisco · Visa sponsorship available

Ownership Areas

You'll take ownership of one or more of these systems as we scale:

Candidate Data Infrastructure - "Senior SWE" and "Sr. Software Engineer" are the same thing, but keyword search doesn't know that. Build the pipeline that parses resumes, pulls from LinkedIn and GitHub, uses LLMs to extract real skills and seniority, and handles 10K+ outbound messages a day without landing in spam.
Agentic Conversation System - Build the agents that text candidates, answer their questions about comp and role details, handle objections, and book calls. Without sounding like a bot or getting facts wrong.
Real-Time Matching Engine - Our AI agent needs to find "React engineer, 3-5 years, SF" and return the right people in under 100ms. Knowing that "React.js" and "ReactJS" are the same, and that 4 years at Google means something different than 4 years at a seed startup.

Who You Are

We're not checking boxes. We want someone who's done hard things and can show their work.

You've shipped production systems that handle real scale. User load, data volume, or complexity that breaks naive approaches.
You're comfortable across the stack. Build a React component in the morning, debug a database query in the afternoon.
You've worked with LLMs beyond basic prompting. Embeddings, RAG, agent architectures, or similar.
You make decisions with incomplete information. Ship, learn, iterate. Not wait for perfect specs.
You've built something from scratch. Side project, startup, internal tool. Something you owned end-to-end.

Don't have all of these? If you've done something impressive that's not on this list, we want to hear about it.

We raised a large pre-seed round to tackle this challenge at scale.
