Backend Engineer
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.
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.
- 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.
- 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
