Senior Backend Engineer – Platform & Reliability (m/f/d)

What you will do

• Own our Azure infrastructure end-to-end You know every service, how it’s deployed and what it costs. You’ll tighten what’s there and codify what isn’t. As we scale, you’ll keep the architecture simple: we run on managed services and plan to keep it that way.
• Bring real observability to the platform
• Metrics, logs, traces and alerts, across our services and the third-party APIs we call. You’ll define what “healthy” means, build the dashboards, and set up alerting and on-call so we catch problems before our clients do. When a mysterious timeout appears, you’re the one who can trace it to its source.
• Raise the bar on security and reliability Fintechs trust us with sensitive financial data. You’ll harden the platform, make sure we can deliver on incident response and SLAs, and keep us audit-ready as customers ask for certifications like SOC 2 or ISO 27001.
• Build product and level up the team You’ll ship features and integrations with the rest of the engineering team. You’ll also be the go-to person for production debugging, and you’ll mentor our engineers so the whole team gets better at running what we build.

• Experience: 5+ years building and running backend services in production, including real ownership of infrastructure, deployments and incidents.
• Production debugging: You’ve chased down latency spikes, timeouts and flaky dependencies, and you know how to go from “something is slow” to the root cause.
• Azure: Solid hands-on experience running production workloads on Azure.
• Observability: Experience instrumenting services with tracing, structured logging and metrics, ideally with OpenTelemetry or similar.
• Infrastructure-as-code mindset: You codify infrastructure rather than clicking through consoles.
• Security by default: You think about secrets, access management, and compliance as part of the work, not as an afterthought.
• Backend skills: You’re comfortable writing production code in TypeScript/Node.js and enjoy shipping features, not only keeping the lights on.
• Pragmatism and mentoring: You pick the simplest setup that works. You enjoy helping less experienced engineers grow, and you’re excited to set the standards for how we run our platform.
