Ruby Labs is a leading tech company that creates and operates innovative consumer products. Our innovative teams are driving the future of consumer-led products, and we are always looking for passionate individuals to join us. We are looking for a disciplined, highly autonomous Middle Next.js Developer to build and ship product features for one of our core D2C subscription products. You will own features end to end across a TypeScript monorepo - a Next.js App Router client, a Fastify + Payload CMS API on PostgreSQL, and Cloudflare Workers at the edge - from the moment you receive a task, through breaking it down, estimating, implementing, testing, and observability, to a clean release to production and confirmation that it works for real users.
This is a hands-on engineering role suited for someone who treats production as the standard, not the finish line. Half-tested code, silent failures, and unverified AI-generated output are not acceptable. You are accountable for every task you take on and for every area of the product you touch: if it breaks, regresses, or stays half-finished,
that is yours to see through. We expect maximum autonomy and real involvement in the product - you work independently within a sprint, communicate risks before they become blockers, and elevate architectural decisions to senior engineers rather than guessing.
