What you’ll actually be doing

As part of a cross-functional product team, you’ll take meaningful ownership across the full software lifecycle:

• Build & scale core services: Design, build, and ship robust backend services, APIs, and business-critical workflows using modern C# and .NET.
• Shape system architecture: Drive decisions on scalability, resilience, and performance for high-throughput distributed systems.
• Turn requirements into reality: Partner with product managers, designers, and domain experts to translate complex business needs into pragmatic technical solutions.
• Elevate the team: Mentor colleagues, conduct thoughtful code reviews, and share knowledge to help the engineering group grow.
• Own production health: Champion automated testing, clean documentation, and reliable deployment practices so we ship with confidence.

Who you are:

You’re an experienced engineer who enjoys untangling complex problems and balances engineering excellence with pragmatic delivery:

• Backend depth: 8+ years of hands-on software engineering experience, with deep expertise in C# and modern .NET.
• Distributed systems: Practical experience designing clean REST APIs, message queues, event-driven workflows, and asynchronous communication patterns.
• Data fluency: Strong background with relational databases (e.g., SQL Server, PostgreSQL), query optimization, and ORMs like EF Core or Dapper.
• Cloud & DevOps: Experience deploying and managing containerized services (Docker/Kubernetes) in cloud environments, ideally Microsoft Azure.
• Observability & troubleshooting: Skilled at diagnosing and resolving complex production issues using logs, metrics, and distributed tracing.
• Pragmatic tooling: Comfortable leveraging AI coding assistants (e.g., GitHub Copilot, Cursor) to move faster, while applying sharp judgment to ensure security and code quality.
• Clear communication: Fluent in English, with the ability to explain technical trade-offs to both engineering peers and non-technical partners.
