Senior Back End Developer

Our client is one of Sweden’s fastest-growing gaming technology companies, powering B2B platforms for online operators worldwide.

They are now entering a major growth phase and building a new team focused on anti-fraud, community services, and next-gen player experiences.

This is a chance to join a small, high-impact engineering group at a formative stage; shipping fast, owning big decisions, and shaping how new products are built.

The team optimises for quality, rapid iteration, and short feedback loops and has full end-to-end ownership, strong engineering autonomy, and a culture centred on experimentation, monitoring, and continuous improvement.

If you want to avoid process paralysis, influence core tech choices, and build things that matter, continue.

You will

• Own products end-to-end: design, build, test, deploy, and monitor in production.
• Work with large-scale, high-availability systems moving millions of events per minute.
• Move fast: build, iterate, release multiple times a day with automated deployment.
• Help shape team culture, engineering practices, and technical direction.
• Design and evolve system architecture with hands-on coding (we are not looking for PowerPoint Architecture).
• Mentor teammates and collaborate closely with stakeholders across the business.
• Learn fast through experimentation; success, failure, and everything in between.

Team Culture

• Small, tight-knit team early in its journey
• Real ownership and autonomy
• Low process, zero meetings, so you can keep building
• A chance to shape culture, tooling, and ways of working
• A fast, sometimes messy, but always exciting environment with driven engineers

We need

• A broad generalist with experience setting up infrastructure and applications to handle enormous amounts of data
• Strong experience across multiple backend languages, ideally Go, TypeScript, Node.js
• Solid grounding in both SQL and NoSQL databases
• Experience with serverless and self-managed cloud services
• Background with event or streaming tech (Kafka, RabbitMQ, Kinesis, Flink)
• Exposure to DevOps practices and deploying scalable systems in AWS
• Experience with high-throughput, high-transaction environments
• A hands-on builder who loves solving real problems, not an architect who stopped coding

If you are a senior engineer who thrives in autonomy, loves fast iteration, and wants to build new products from scratch with talented peers, this is the place to make a huge impact.
