• Collaborate with DevOps and QA functions to trace issues across deployment pipelines, APIs and operational environments.
• Refactor and enhance existing modules to increase performance, reliability and maintainability.
• Create and maintain documentation of key technical findings, and build diagnostic and troubleshooting frameworks that can be reused.

Required Skills & Background

• Minimum of 8 years’ experience in professional software engineering, delivering production-grade systems.
• Expert proficiency in C# and .NET (Framework 4.8 and/or .NET 10+), with an emphasis on clean, secure, scalable code.
• Strong experience with SQL and relational database systems (e.g., MSSQL, MySQL), along with exposure to ElasticSearch and Redis.
• Demonstrated ability to design, build and optimise distributed, high-volume data flows and integration patterns.
• Solid familiarity with IIS, Docker, Kubernetes (EKS), and containerization on both Windows and Linux platforms.
• Hands-on experience with AWS (including but not limited to EKS, EC2, RDS, S3, CloudWatch).
• Practical experience working with CI/CD and automation tools such as GitHub Actions, TeamCity, Terraform.
• Awareness of monitoring and security tools such as Prometheus, Grafana, GuardDuty, AWS Inspector, New Relic.
• Excellent verbal and written communication skills and ability to thrive in a fast-moving, cross-functional engineering environment.

What We Offer

• Fully remote working arrangement from Ireland.
• Flexibility to work from anywhere in the world for certain periods each year.
• Flexible working hours aligned to outcomes rather than fixed location or schedule.
• Pension plan and a genuinely supportive engineering culture.
