We're one of the world’s fastest-growing AI companies. We've achieved a 20x increase in ARR and raised $75M+ from leading investors including a16z and Benchmark. Our team works in-person in our San Francisco office.
About the Role
We’re looking for a Staff Software Engineer with deep fullstack expertise and a passion for building ambitious AI-powered systems. In this role, you’ll operate as a technical lead—driving architecture, product development, and internal standards for one of our flagship autonomous digital workers.
You’ll collaborate closely with our CTO, cross-functional teams, and model providers to translate complex ideas into elegant, production-ready software. This is a hands-on leadership role where you’ll influence system design, mentor other engineers, and set the bar for engineering quality in a fast-moving, AI-native environment.
What You’ll Do
Architect, build, and scale fullstack systems that support autonomous AI agents in production.
Lead technical decision-making across projects—ensuring long-term scalability, reliability, and developer efficiency.
Evaluate new technologies, model APIs, and prompting strategies to enhance agent performance and alignment.
Collaborate cross-functionally with design, product, and GTM teams to define roadmaps and prioritize development.
Drive internal engineering standards through mentorship, documentation, and code reviews.
What We’re Looking For
6+ years of experience in software engineering, with demonstrated leadership on complex technical projects.
Strong command of modern fullstack frameworks—especially Typescript, React, NextJS, and NodeJS.
Track record of shipping scalable systems in high-growth or startup environments.
Strategic thinker who can balance speed and quality while driving technical vision.
Bonus: experience with LLMs, agent orchestration frameworks, or AI infrastructure.

Our technology integrates across GTM systems, adapts to real business logic, and learns continuously while delivering real outcomes. These aren’t just incremental improvements, they’re game-changing leaps forward in how companies grow.
Why Work With Us
Everyone here is a builder. You’ll be starting at the ground floor of a rocket ship company with the rare opportunity to leave your mark, shape the culture, and have a seat at the table as we scale. You’ll work side-by-side with a world-class team—people who move fast, think deeply, and care fiercely.
The upside? Massive.
