## About the Role

* Strong grasp of C# and .NET development
 * Experience with event-driven systems - We use Azure Service Bus, but would love to hear from you if you have experience with similar messaging technology (Kafka, RabbitMQ, etc.)
 * Microservices architecture experience, ideally on Azure and Kubernetes
 * Experience using observability tooling (e.g. Grafana, Application Insights) to understand production behaviour
 * Comfort using AI tools as part of a daily engineering workflow (design, code review, testing, incident investigation)
 * DevOps culture mindset, including on-call/production ownership
 * Proven ability to collaborate effectively in distributed teams across time zones
 * Continuous learning mindset and openness to feedback

## Description

* Modern C# stack: Distributed C# and .NET microservices
 * Cloud & orchestration: Hosted on Azure using Kubernetes
 * Architecture: Event-driven, supporting products used at significant scale
 * Observability: Grafana, Azure Application Insights, logs, traces, and metrics
 * AI tooling: Claude and other AI tools used throughout the engineering workflow - design exploration, code generation and review, test writing, incident investigation, and technical communication

Our Engineering Approach

 * AI-native engineering: We want engineers who tinker - experimenting with new tools, agents, and workflows, and sharing what works
 * Guardrails as we accelerate: Automated tests, SLOs, alerting, observability, and deployment safeguards around everything we ship
 * Own it beyond the pull request: Design for idempotency, retries, out-of-order events, and failure modes, and know how your services behave in production
 * The Campfire Rule: Leave the systems you touch a little better than you found them
 * On-call as feedback, not heroics: Engineers who build our systems also help operate them, using incidents to make the platform more resilient, We're looking for a senior engineer who's curious, autonomous, and highly trusted. You're comfortable owning the entire software stack - including supporting infrastructure - throughout its lifecycle, and you see production data, not just deployment, as the real measure of "done."
