Senior Engineer - Java, AWS

Overview

Senior engineer role on the Prime Core team, which builds and runs the open-spec trading APIs and solutions serving institutional and retail clients, including real-time price distribution, order and execution flow, and reference data.

What you'll do

• Write production Java that other people have to maintain: tested, readable, and honest about its edge cases.
• Work in a spec-driven, AI-assisted development workflow, specifying intent clearly, using AI tooling to move fast, and reviewing its output critically.
• Contribute to design discussions and technical decisions.
• Deploy and run what you build in AWS, and learn how the cloud behaves when things go wrong.
• Work with the wider team to investigate production issues using logs, metrics, traces and JVM diagnostics.
• Take ownership of services, and help the engineers around you grow through mentoring and code review.

What you'll need

• 7 to 12 years of professional Java development experience, including hands-on AWS.
• Solid commercial experience writing Java in a production environment.
• Real understanding of JVM runtime behaviour: memory management and garbage collection, the Java memory model, and thread interaction.
• Working knowledge of concurrency and multi-threading, including visibility problems, contention, and bugs that appear only under load.
• Practical JVM diagnostics skills: reading thread and heap dumps, reasoning about GC behaviour, profiling, and narrowing down memory leaks or contention problems.
• Experience with the Spring Framework, ideally Spring Boot.
• Hands-on AWS experience: you have deployed and debugged something real in the cloud and understand the services you used.
• Practical experience using AI coding tools as part of your normal workflow, with the judgement to know when their output is wrong.
• Comfort on Linux, including basic shell scripting.
• Curiosity and persistence in digging into problems, and willingness to ask questions early and often.
