With 25 years of industry presence and a team of 140, this organisation values craftsmanship, stability, and long-term thinking over short-term delivery. Their product is central to storytelling in media so reliability, performance, and usability truly matter. The opportunity: This is not just another senior engineering role. You’ll operate as a technical leader and thought partner, contributing to architecture, guiding engineering standards and influencing how systems evolve over time. While you’ll remain hands-on, your impact will extend beyond your own code, shaping decisions, mentoring others and elevating the team. You’ll work across the full stack, owning everything from elegant frontend experiences to robust backend services and infrastructure, with the autonomy to make meaningful technical decisions. What you’ll be doing: \* Leading the design and evolution of full-stack architecture across frontend, backend, and serverless systems \* Building high-quality, performant applications using React and Next.js \* Designing and scaling Node.js APIs and distributed backend services \* Driving best practices in code quality, testing, observability and maintainability \* Partnering closely with product, design, and research to shape solutions end-to-end \* Acting as a technical sounding board and mentor within a collaborative team \* Contributing to decisions around tooling, infrastructure, and emerging technologies (including AI-assisted workflows) What success looks like: Within your first 6–12 months, you will have: \* Shaped key architecture decisions across the platform \* Delivered scalable, production-grade Node.js services supporting critical workflows \* Shipped polished, high-impact frontend experiences used daily by customers \* Improved system performance, reliability, and scalability in measurable ways \* Elevated engineering standards through thought leadership, mentorship, and best practices Tech environment: \* TypeScript / JavaScript \* Node.js (API & backend services) \* React, Next.js \* AWS Serverless (Lambda, API Gateway) \* Vercel \* SQL Server \* Algolia \* CI/CD (TeamCity) You’ll thrive here if you: \* Are a senior or staff-level engineer who enjoys owning problems end-to-end \* Think beyond implementation — you care deeply about architecture, trade-offs, and long-term impact \* Have strong experience building Node.js backends and modern React applications \* Enjoy working as a true full-stack generalist, comfortable across frontend, backend, and infrastructure \* Naturally contribute ideas, challenge thinking constructively, and raise the bar for those around you \* Value collaboration, clarity, and thoughtful engineering over quick fixes What you’ll find: \* A mature, craft-led engineering culture \* Real influence over technical direction and product decisions \* A highly collaborative, cross-functional environment \* The space and trust to solve problems properly \* A stable, successful business with meaningful impact in music and media This isn’t about chasing trends or shipping fast at any cost. It’s about building the right things, the right way and having the experience and perspective to lead others in doing the same.
