Lead Developer – Full Stack

We’re looking for a Lead Developer (Full Stack) to own the product layer of our system. You’ll be responsible for the frontend experience and the API/application layer—working across the stack to deliver reliable, end-to-end product workflows. You’ll collaborate closely with backend/data engineers and SRE, shaping how systems come together at the product layer, and contributing wherever needed to ship features. You’ll play a key role in moving us from early deployments to a repeatable product across multiple facilities. This is a high-ownership role. You will define patterns, unblock teams, and help shape how the product works—not just how it’s implemented. We've found tremendous value in collaborative problem-solving, so our team works from our SF office three days a week.

• Drive the development of our frontend (Next.js / TypeScript), leveraging modern code-generation agentsArchitect and oversee the API/application layer, focusing on system integration, security, and data integrity

• Design robust end-to-end product workflows, acting as the primary reviewer and quality gatekeeper for automated code contributions

• Implement strict automated testing and CI/CD pipelines to ensure reliability and safety of the features

• Build and maintain:

  • Customer-facing UI for live operations and analytics

  • Internal tools for configuring and deploying facilities

• Collaborate with product to translate high-level requirements into concrete workflows and implementations

• Collaborate with backend engineers to define and evolve API contracts and data interactions

• Improve performance, reliability, and maintainability of the frontend

• Implement and maintain frontend and API testing and CI workflows

• Own authentication flows and system integration at the product layer

• Strong experience with TypeScript and React (Next.js or similar)

• Experience building and maintaining API layers using backend frameworks (Python, Node, or similar)

• 5+ years building and shipping production systems

• Experience owning end-to-end features or products, not just isolated components

• Comfortable working across the stack (frontend + API layer)

• Strong ownership and product mindset, with the ability to operate in ambiguous, fast-moving environments

• Experience building real-time or data-heavy applications (e.g., streaming, time-series, or analytics systems)

• Experience working with authentication systems (e.g., login flows, session management, SSO integrations)

• Experience working with systems deployed outside pure cloud environments (e.g., on-prem, edge, or hardware-integrated systems)

• You will often start from high-level product goals, not detailed specifications. You’re expected to help define:

  • workflows

  • user interactions

  • system behavior

• You’ll collaborate with product and design, but also fill in gaps and move work forward independently

We’re scaling from a small number of deployments to many, and this role is critical in making that happen. We need:

• A product layer that can support multiple facilities and configurations

• Internal tools that make deployments repeatable

• Clear workflows that work in real-world environments
