You'll work directly with the CTO and CPO, not through layers of management. You'll be in the room when decisions get made and have real input on what we build and how. We call this a "Product Engineer" role because you won't just implement tickets. You'll own features end-to-end, make product calls, and ship things that matter to real users. Tech stack: Node.js (primary for new code), some legacy Go (~20%), React/TypeScript on frontend. Infrastructure on GCP with Terraform. Typical split: ~60% backend/infra, ~40% frontend - varies by project. What You'll Actually Do + Ship full features, end-to-end - From schema design to API to UI. You'll own the whole vertical, not just one layer. + Build and maintain infrastructure - GCP, Terraform, CI/CD pipelines. You'll keep the systems running and improve them over time. + Optimize databases - Write complex queries, tune performance, design schemas that scale. + Make product decisions - See a better way to solve a user problem? Propose it and build it. We trust engineers to make smart calls on technical and product decisions. + Build with AI tools - We use Claude Code, Cursor, and other AI tools daily. You should be comfortable (or excited) to work this way. + Own your code in production - Continuous deployment means what you merge today is live today. You'll debug, monitor, and improve what you build., Let's be honest about fit: + Not a chill 9-to-5 - Startup means more ownership, higher stakes, and hard pushes around launches. We respect personal time and recover after sprints, but when we ship, we ship hard. + Not highly structured - If you need detailed specs and clear roadmaps to function, this isn't the place. + Not backend-only - You'll spend real time in React. If you want pure backend/infra, this isn't the role. + Not frontend-heavy - If you want to go deep on UI/UX, we have a Frontend Product Engineer role. Growth You'll join as one of 5 engineers, growing to 10+. As we scale, there's a clear path to tech lead or staff engineer for the right person. You'll help shape engineering culture, not just inherit it. ## 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) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [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 - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift)
