Description

We're looking for a senior Java developer who can independently build recent microservices from scratch — including setting up build tooling and CI/CD — not just extend existing ones. You'll work across legacy code understanding, modern Java development, and relational database performance, using AI tools as a collaborator to accelerate (not replace) your engineering judgment.

Responsibilities

What You'll Do
Design, build, and stand-up new REST microservices end-to-end, including build/CI-CD setup
Read, debug, and extend unfamiliar and legacy codebases
Write and troubleshoot SQL, including validating and optimizing Hibernate-generated queries
Write meaningful automated tests that catch real regressions, not just green checkmarks
Use AI tools (e.g., ChatGPT, Claude) to accelerate research, documentation, and problem-solving

Qualifications

Required Experience & Skills

Core Stack
~10 years of professional software development experience
Strong Java 8+ (8, 11, 17, 21) — comfortable with modern syntax (var, records, text blocks, switch expressions)
Spring Framework / Spring Boot
Hibernate / JPA
REST Microservices — including creating current services from scratch
Build tools: Gradle (preferred) or Maven
CI/CD: Bitbucket (preferred)
Cloud: AWS (preferred)




Database & Performance
Robust relational database concepts and SQL proficiency (read, write, and debug queries — including jOOQ)
Indexing strategies
Query optimization
Schema design
Production troubleshooting

Testing
JUnit (4 or 5) — test structure, assertions, setup/teardown, mocking, test isolation
A genuine testing mindset: skepticism that 'it compiles' means 'it works'
Integration testing strategies, including end-to-end testing and test data management

Engineering & Problem-Solving Fundamentals
Ability to read and understand unfamiliar or legacy code
Strong debugging and troubleshooting skills, including reading stack traces
Dependency management knowledge
Quick learner with strong research and pattern-recognition skills
Ability to break large problems into manageable pieces
Knows when to ask for help

AI-Assisted Development
No specific AI tool expertise required — but candidates should have genuine experience using AI (e.g., ChatGPT, Claude) as a development collaborator for research, explaining concepts, and drafting documentation, treating it as a partner rather than an oracle.
