.Net Backend Developer

Our requirements

• Solid backend experience (roughly 7+ years) building distributed systems in .NET, including running services on Kubernetes in Azure. Python for AI/ML workloads is a nice-to-have.
• Strong architectural judgment and the willingness to make calls and defend them.
• Experience integrating LLM APIs (Anthropic, OpenAI, or similar) into production systems, or a clear track record that suggests you'll pick it up fast. We're model agnostic and not locked into a single provider.
• Calibrated views on AI tooling: enthusiastic about what it does well, honest about where it falls short, and effective at using it day-to-day.
• Deep understanding of system reliability, scalability, and failure modes, and hands-on experience monitoring production systems (logs, metrics, traces, alerting).
• Hands-on experience with event-driven integration: webhooks, REST APIs, and messaging/streaming platforms such as Azure Event Hubs.
• Fluent English and the ability to discuss complex technical topics clearly.
• High ownership and the kind of self-direction that thrives in a small team.

Your responsibilities

• Build and evolve the integration between Teamtailor and our ecosystem in .NET, running on our Kubernetes infrastructure in Azure.
• Bring suggestions on where AI could add value in the integration, such as enrichment and automation.
• Pair with our architects on big technical calls; own the domains you work in end to- end.
• Build reliable integrations with Teamtailor and other external systems: webhooks, REST APIs, and event streaming via Azure Event Hubs (retries, idempotency, circuit breakers, versioning).
• Apply DDD to keep the system aligned with how recruitment and consultant matching actually work.
• Design secure-by-default systems (OAuth2, JWT, managed identities, rate limiting).
• Use AI tools (Copilot, Claude Code, Cursor, and whatever comes next) to move faster, and critically evaluate what they produce, especially for distributed systems edge cases.
• Own production for business-critical workloads: monitoring, alerting, tracing and dashboards that show.
