Production Support Engineer Job at Eftsure (North Sydney)

Job Description

Be the technical bridge between Support and Engineering. Lead incident response, uncover root causes, and drive meaningful improvements across Eftsure's fraud prevention platform. At Eftsure, we're on a mission to protect businesses from fraud and payment risk. Trusted by thousands of organisations across Australia, New Zealand and beyond, our platform helps finance teams make every payment with confidence. We're looking for a Production Support Engineer who thrives on solving complex technical problems, digging into root causes, and making systems more reliable. This isn't a traditional support role. You'll sit at the intersection of Engineering, Product and Customer Operations, using your technical expertise to investigate production issues, improve platform stability, and help prevent problems before they happen. If you're the type of person who sees recurring incidents as engineering problems to solve, not tickets to close, we'd love to hear from you.

Maintain clear and timely communication throughout incident lifecycles
Investigate Complex Production Issues
Analyse logs, telemetry, stack traces and application behaviour to identify root causes
Use tools such as Splunk, Grafana and SQL to diagnose issues
Differentiate between code defects, configuration problems, data issues and infrastructure-related failures

Strong SQL skills and experience investigating complex data issues
Experience working with observability and monitoring platforms such as Splunk, Grafana or similar
Ability to read and debug application code (experience with C#, Java or similar languages is highly regarded)
Understanding of web applications, APIs and cloud-hosted SaaS environments
Familiarity with CI/CD pipelines and deployment processes
Experience using Jira or similar issue-tracking tools
