Job description

GoWish, Ønskeskyen Copenhagen Full-time

Salary Competitive

About GoWish, Ønskeskyen

At GoWish, we’re building the world’s leading wish-list and social shopping platform — a place where you can make a real impact and have fun doing it.

We’re on a mission to reinvent gifting for millions. We win together, driven by curiosity, ownership, and bold ideas that turn into real products. We experiment cross-functionally, push for excellence, and keep things playful as we grow — together.

Team & role overview

We're Personalization — the team that keeps GoWish feeling alive. People come to us to create wishes, find the perfect gift, and discover things they didn't know they wanted. Our job is to make sure there's always a reason to come back. Put simply, we keep active users active.

Our work spans six areas: Gift Generator, Recommendations, Activity, Creators, Brands, and Partners. Together they shape almost everything a user sees and does on the platform.

As our new Backend Engineer, you'll build and own the services that power all of it — designing APIs and data flows that feel instant and personal at scale. You'll work closely with frontend, product, and data, with real ownership over how millions of people experience GoWish.

Responsibilities

• Design, build, and operate backend services using TypeScript and NestJS
• Build and evolve GraphQL APIs that internal teams and consumers use
• Take ownership of services end-to-end, including architecture, deployments, monitoring, scaling — confirm scope
• Participate actively in architectural discussions, code reviews, and technical roadmap planning

What We’re Looking For

• 5+ years as an Engineer with 3+ years owning backend systems.
• Strong experience with TypeScript
• Hands‑on experience with NestJS
• Solid experience working with GraphQL
• Confident with Git and version control
• Experience working with APIs
• A good understanding of SQL

It is further seen as an advantage to have experience with

• Google Cloud Platform
• PostgreSQL
• Docker
• Drizzle or other ORMs
• Datadog

We also imagine that you:

• Use AI as a tool — not as an autopilot. You stay critical of what AI hands you, and you never pass a PR along without having been through the code yourself. AI is a big part of our everyday, and it should be — but that takes knowing when and how it makes sense to lean on it.
• Communicate well about your work. We keep each other in the loop on what we’ve got going, far beyond standups. Coordination is a fixed part of the way we work.
• Have an eye for both the short and the long game. You can see what’s needed right now and what pays off down the line — and you know the two don’t always pull in the same direction.
• Are flexible and creative in your approach. You’re not locked into one particular way of coding or working. Wanting to do things properly is a good thing, but sometimes reality calls for a creative solution — and you’re ready to find it.
• Can stand on your own two feet when that’s what’s needed. We often pick up work as a whole team, but the tasks itself usually sit with the individual developer. So we need to be able to count on you to carry a task all the way to the finish line: either solving it yourself or moving it forward so someone else can take over.

Why GoWish should sit at top of your career wish list

At GoWish, we believe great work comes from people who feel energized, supported, and excited to show up every day. That’s why we’ve built a workplace where celebration, growth, and genuine enjoyment are part of the journey — not perks on the side.

Take your birthday off with Happy Birthday Leave, enjoy 30 days of vacation to fully recharge, and join a team that fills the year with events and playful happenings. We invest in your future with pension and insurance, fuel your days with a weekly lunch scheme, and keep you going with unlimited snacks and sodas — because work should feel good.

At GoWish, you don’t just build great products. You build a great work life.
