Senior Software Engineer – Full Stack

Summary

A Senior Full Stack Engineer owns the product layer, designing and implementing end-to-end workflows for customer-facing UIs and internal tools using Next.js/TypeScript and FastAPI, while collaborating with backend/data teams to shape system integration and scalability across multiple facilities.

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

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
