This role will offer you the chance to be one of the people defining them. If you want your fingerprints on the foundations rather than the tenth engineer shipping inside someone else's decisions, this is that role! What you'll actually be doing * Designing, building, and owning real pieces of our Go backend (Including services, data models, APIs) * Driving the technical evolution of our markets platform end to end, working shoulder-to-shoulder with product and design * Integrating with backend APIs and platform teams to build systems that are reliable and genuinely observable * Leading design, build, and ship of high-quality, scalable web experiences in React, Next.js, and modern TypeScript * Owning features end-to-end: spec * build * instrument * deploy * monitor * iterate. * Designing feature flags and experimentation tooling so we can validate ideas fast and safely * Setting the bar in code review AI Assisted engineering They want engineers who've gone past the novelty phase with Claude Code, Cursor, Copilot, or similar & who use these tools daily to ship production code faster without cutting corners on quality. If you can point to a real example of how AI tooling changed your workflow (not just "I used it," but a measurable before-and-after) they will want to hear about it. You'll help set team standards for this: prompt patterns, review checklists etc ## Related Videos - [WeAreDevelopers LIVE – AI, Freelancing, Keeping Up with Tech and More](https://www.wearedevelopers.com/videos/1786-wearedevelopers-live-ai-freelancing-keeping-up-with-tech-and-more) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [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) - [GraphQL + Apollo + Next.js: A Lovely Trio](https://www.wearedevelopers.com/videos/311-graphql-apollo-next-js-a-lovely-trio) - [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) - [How Much Does a Software Engineer Make?
