Senior Application Support Engineer

Senior Application Support Engineer - Java

We’re partnering with a leading financial services organisation to hire a Senior Application Support Engineer into a team supporting a large-scale digital wealth platform used by financial advisers to manage client portfolios, transactions and reporting.

This is not a traditional application support role.

The team is looking for an engineer who enjoys solving complex production problems, working across Java applications, microservices, APIs, logs, data and cloud infrastructure to understand what has gone wrong, identify the root cause and improve the system so the same issue is less likely to happen again.

You’ll work closely with engineering, product and support teams, taking ownership of incidents from initial investigation through to resolution.
What you’ll be doing

• Investigate and resolve complex production issues across Java-based applications and microservices
• Read and troubleshoot Java code to understand system behaviour and identify root causes
• Use logs, monitoring, tracing and data to diagnose issues across distributed systems
• Work with tools including Sumo Logic, Dynatrace, GKE and Jira
• Investigate issues across accounts, payments, trading and reporting
• Use SQL to investigate application and data-related problems
• Improve monitoring, diagnostics and incident response
• Automate repetitive support and operational processes
• Build tools that improve how the team investigates and resolves production issues
• Work closely with software engineering, product and wider support teams
• Contribute to documentation, knowledge sharing and continuous improvement

The environment

The platform operates across modern Java, cloud, APIs and microservices, with applications currently running on Java 21 and Java 25.

AI is also embedded into the way the team works. Engineers use Claude Code alongside Sumo Logic, Dynatrace, GKE, Jira and internal tooling to assist with areas such as log analysis, triage and incident investigation.

There is no on-call roster or regular after-hours rotation, although additional support may occasionally be required during significant production incidents.

What we’re looking for

You’ll ideally come from an application support, production engineering, SRE or software engineering background where you have been responsible for diagnosing complex production issues.

You should have:

• Strong Java knowledge with the ability to read and troubleshoot production code
• Experience investigating production systems and performing root-cause analysis
• Experience with monitoring and observability tooling such as Splunk, Sumo Logic, Dynatrace, Datadog or AppDynamics
• Working SQL knowledge
• Experience working with APIs and microservices
• Strong communication skills and the ability to explain technical issues clearly
• A mindset focused on solving underlying problems rather than applying short-term workarounds

Experience with GCP, AWS, Azure, Kubernetes or GKE would be beneficial, as would experience automating operational or support processes.

This role would suit someone who enjoys being close to the code but is particularly motivated by debugging, production reliability, incident investigation and solving difficult technical problems rather than purely feature development.

Permanent - $180,000 - $230,000 package plus annual bonus. 3 days in the office per week.
