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 Senior 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
  • + 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
  • 6+ years building backend systems (ideally integrations) with  + 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
  • Gaming/fintech/e-commerce integrations (wallets, catalogs, identity, compliance)

  • Experience in regulated environments with staged rollouts

Success looks like
  • Cutting time-to-integrate new providers from weeks to days

  • Improving observability, testability, and reliability at scale

  • Becoming a go-to engineer for design and debugging while uplifting others
