Our Mission

We're revolutionizing productivity by building AI-powered collaborators that automate busywork. Our platform enables customizable, no-code AI agents to manage complex workflows (inbox/lead management, reporting, cross-app integrations, etc.), freeing humans to focus on high-impact work. Join us to shape the next evolution of work.

The Role

As a Full-Stack Software Engineer, you’ll build and scale the core platform of our AI agent ecosystem. You’ll own end-to-end feature development in a full-stack TypeScript environment (React, Node.js, Next.js, GraphQL) and drive infrastructure decisions for a product used daily by thousands. Expect minimal bureaucracy, high ownership, and a culture of urgency.

You’ll Thrive By

1. Shipping critical features fast with meticulous attention to detail and maintainable code.
2. Owning features end-to-end: requirements, code, testing, observability, deployment, and maintenance.
3. Collaborating with founders, PMs, and designers to solve hard product/engineering trade-offs.
4. Optimizing distributed systems for scalability, reliability, and real-time performance.
5. Working in-office 4 days/week (San Francisco). Visa sponsorship and relocation (up to $20K) provided.

Who You Are

1. 3+ years building production-grade software.
2. Independent, impact-driven, and thrive in ambiguity.
3. Exceptional debugger and systems thinker.
4. Strong communicator who elevates team collaboration.
5. Committed to in-person work (SF office, 4 days/week).

Tech Stack & Bonus Skills

1. Core Stack: TypeScript, React, Node.js, Next.js, GraphQL.
2. Distributed Systems: Queuing/streaming, consistency models, reliability patterns (retries/caching).
3. Realtime Tech: WebSockets, socketcluster.
4. API & AI Expertise:
5. Integrating 100+ third-party APIs (Slack, HubSpot, Gmail, etc.).
6. LLM APIs (token streaming, action calls, agentic workflows).

Why Join

1. 💰 Compensation: $150K–$220K base + generous equity.
