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.

KEY RESPONSIBILITIES

• 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

REQUIRED QUALIFICATIONS

• 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

PREFERRED QUALIFICATIONS

• 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)

HOW WE WORK WITH PRODUCT & DESIGN

• 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

WHY THIS ROLE MATTERS

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

Engineers who can move quickly without breaking the system
