- world production reliability. You’ll also support and guide junior engineers, promoting software development design patterns and other best practices, raising engineering standards and delivery quality.

What you’ll do

• Design and build backend services primarily in C#/. NET , with clean APIs and strong engineering fundamentals
• Build and evolve agentic systems (tooling, orchestration, workflow execution, guardrails, observability)
• Own quality: testing strategy, CI/CD practices, code reviews, and release confidence
• Own

• Comfortable with testing (unit/integration/e2e), and debugging complex distributed systems
• Experience working with distributed systems and concurrency (async patterns, race conditions, reliability)
• Strong communication skills and a “raise-the-bar” mindset

Nice to have

• Python experience (especially for tooling, data workflows, or AI/agent integration)
• Hands-on experience building agentic systems (agents, tool calling, orchestration, workflows,
  - step reasoning)
• Observability/production readiness: tracing, metrics, structured logging, incident response practices
• Cloud and modern deployment practices (containers, CI/CD, infrastructure as code)
• Debug and profile distributed, concurrent systems (latency, throughput, contention, async issues, memory/CPU)

What success looks like

• You ship
  - grade features with measurable reliability and performance
• Junior team members become noticeably more effective, disciplined, and autonomous
• The codebase becomes easier to maintain and grow: cleaner code, better tests, clearer standards

How to apply

Send your CV/Linked
In plus a short note covering:

• The most complex distributed/concurrent issue you debugged, and how you diagnosed it
• A time you helped a junior team member produce high quality outputs (what you changed and what improved)
