Backend Engineer

Senior Backend Engineer (Systems & Production) Perm Role Cork - Hybrid 1 day week onsite

A client of mine is hiring a senior backend engineer to focus on how systems behave in production. The successful candidate will work across a distributed, event-driven SaaS platform, improving performance, reliability, and correctness at scale. This role sits between backend engineering and production systems-shaping how services are designed, built, and operate under real-world conditions.

The Job:

• Improve system performance, scalability, and reliability under real production load
• Identify inefficiencies in code, data models, and service interactions
• Design for safe retries, idempotency, and predictable behaviour
• Contribute to backend services in C# / .NET
• Debug complex issues across distributed systems and async workflows
• Improve observability (logging, metrics, tracing) so systems are diagnosable
• Influence engineering standards, design decisions, and code quality across teams

Have you:

• Strong backend experience in C# / .NET (or similar)
• Experience working on complex, distributed systems (not just CRUD apps)
• Ability to reason about concurrency, failure modes, and eventual consistency
• Experience diagnosing performance issues and data-related bottlenecks
• Solid understanding of SQL and/or NoSQL at scale
• Pragmatic mindset with a focus on root cause analysis and real-world behaviour
• Experience with event-driven or actor-based systems (e.g. Akka.NET)
• Experience in multi-tenant SaaS platforms
• Familiarity with Kubernetes and CI/CD
