Share this job
We are on a mission to pioneer the world’s next era of play. As we grow across Europe and Latin America, we’re building The Playstack - the technology powering the next generation of sports, gaming, and fan experiences. Join us, and help make it the most widely used platform in the world! From operations, to marketing, to product, we are looking for talented people who will shape how millions of customers play, watch, and connect every day.
🚀 Why this role matters
Happening powers the technology behind Superbet’s platforms and brands, serving millions of customers. Our Game Integrations squad connects third-party providers to our core platform and ensures those experiences are reliable, scalable, and compliant.
We’re growing and scaling fast, and we need a Backend Engineer who can deliver high-quality integrations, shape engineering standards, and help accelerate how quickly new providers go live.
How we work: We’re product-minded squads with strong ownership, candid feedback, and measurable outcomes. We build, run, and continuously improve the tech that powers Superbet’s customer experience.
What you’ll do
-
Build integrations end-to-end - design contracts, implement services, write tests, and ship with confidence.
-
Own reliability - define SLIs/SLOs, set up observability (metrics, logs, traces), and join on-call.
-
Keep systems healthy - tackle production issues, reduce tech debt, and simplify through pragmatic refactors.
-
Work across boundaries - collaborate with Product, Compliance, SRE, Data, Security, and external partners to keep delivery smooth.
- Level up the team - mentor more junior teammates through sharp code reviews, pairing, and knowledge sharing.
🛠️ Tech we use
-
Node.js + TypeScript (backend services & integrations)
-
Kubernetes (K8s) in production, CI/CD pipelines, containerized deployments
-
REST APIs with versioning & backward compatibility
-
Observability stack → metrics, tracing, logging, dashboards, and alerts
What we’re looking for
-
3+ years building backend systems (ideally integrations) with Node.js + TypeScript
- Event-driven systems (Kafka) and low-latency/high-throughput workloads
-
Solid production experience with Kubernetes and CI/CD pipelines
-
Strong background in API design (REST) and maintaining compatibility at scale
-
Focus on testing & quality (unit, integration, QA collaboration)
-
Ability to write clear docs and status updates that keep teammates aligned
Nice to have
- Experience with Nest.js
-
Gaming/fintech/e-commerce integrations (wallets, catalogs, identity, compliance)
-
Experience in regulated environments with staged rollouts
