Senior SRE (Java)

I am currently partnering with a major FTSE 100 FinTech company that is undergoing a massive modernisation and observability overhaul. They aren't looking for a traditional, infrastructure-heavy SRE; they need a Senior Java Developer who has recently transitioned into the SRE space.

My client operates high-performance trading platforms for over 340,000 global users. They need an engineer who can "get under the hood" of a Java codebase to build, debug, and instrument for high-scale reliability while defining the standards for their future cloud-native architecture.

• True Engineering Ownership: You'll be helping the division from the ground up by defining SLOs/SLIs and implementing OpenTelemetry (Otel) and tracing across distributed systems.

• Modernisation at Scale: This is a "roll up your sleeves" environment moving heavily toward cloud-native services and containerised infrastructure.

• High Visibility: You will bridge the gap between code and infrastructure, working directly with internal departments and the UK leadership team to champion reliability patterns.

• Complex Challenges: You'll work with high-throughput, low-latency trading operations that demand zero downtime, focusing on JVM performance tuning and message-driven systems.

• The Foundation: 5+ years of Java development experience with a deep understanding of JVM internals.

• The SRE Pivot: Recent experience in a Site Reliability or Observability role, with hands-on knowledge of OpenTelemetry, Jaeger, or similar tracing tools.

• The Mindset: A strong philosophy on what makes a "good" SLO and a passion for eliminating toil through automation.

• Technical Breadth: Experience with message brokers (Kafka, ActiveMQ), containerization (Nomad/Docker), and troubleshooting distributed systems.

• Systems Thinking: A passion for both software development and reliability engineering, applying discipline to solve operational challenges at scale.

• Flexible Benefits: A 12% flexible fund on top of your base salary to spend on what matters to you (medical, dental, etc.).

• Generous Time Off: 25 days holiday, plus your birthday off and 2 days for voluntary work (28 total).

• Health & Wellbeing: Private medical cover for you and your family, plus contributions to gym memberships.

• Growth: Unlimited access to LinkedIn Learning, tailored development programs, and mentoring with senior leaders.

• Inclusive Culture: Active employee-led networks (LGBTQ+, Women's, Black, and Parents & Carers) with dedicated budgets for events and projects.

If you are a Java expert who has found your calling in Reliability and Observability, I would love to discuss the company, the role, and the compensation package with you.
