Full description
We’re looking for a Senior Full Stack Engineer 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
