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., * Own development of our frontend (Next.js / TypeScript) * Own the API / application layer (FastAPI or future stack) * Design and implement end-to-end product workflows, not just individual components * 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, * 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 ## Related Videos - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Intro to FastAPI](https://www.wearedevelopers.com/videos/462-intro-to-fastapi) - [Build and Deploy a Fullstack App with Open Source Tooling](https://www.wearedevelopers.com/videos/775-build-and-deploy-a-fullstack-app-with-open-source-tooling) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [React Developer Salary [2023]](https://www.wearedevelopers.com/magazine/198-react-developer-salary-2023) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [The 7 Most Popular Backend Frameworks for Developers](https://www.wearedevelopers.com/magazine/403-the-7-most-popular-backend-frameworks-for-developers) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers)
