Founding Engineer - Full Stack

Gamut is building the agent workforce. We're a seed-stage team backed by Human Capital (SpaceX, Snowflake, Anduril) building a platform that allows non-engineers to build AI employees that get the whole job done. Early customers are already automating several hours of their workday across their most complicated tasks in sales, marketing, ops, etc.

We're hiring people who want to build, not manage. If you want to work on hard problems with a small team that ships, this is the place.

As a founding full-stack engineer, you’ll own the application layer of our platform - from observability and permissions to the control plane and user-facing dashboards that make our agent infrastructure usable and delightful. You’ll work across the stack, turning complex systems into simple, powerful tools for developers.

You will:

• Build the agent interface that non-technical users interact with daily, where they assign tasks, watch agents work, and review results.

• Design and implement the backend systems that orchestrate agent sessions, enforce permissions and guardrails, and capture activity logs.

• Lead architecture decisions around system design, scalability, and reliability.

• Lead & influence product decisions.

• Work directly with early customers to understand pain points and shape our roadmap.

• Own features end to end - from concept through design, implementation, launch, and iteration.

• This role is in-office, 5 days/week, based in San Francisco.

We’re looking for product-minded engineers who love building polished, high-leverage infrastructure and tools. You should be comfortable working across the stack and owning large, impactful projects from day one.

• Building full-stack web applications with modern frameworks (React, Next.js, TypeScript, Node.js, etc.)

• Shipping fast and iterating quickly

• Deploying and scaling applications in the cloud (AWS, Terraform, Docker, Kubernetes, etc.)

• Thriving in high-agency, high-ownership environments

• Competitive salary, based on experience level (Annual compensation range: $50,000 to $500,000)

• Meaningful equity

• Health, dental, and vision coverage

• Opportunity to be a founding member of a growing company
