Job Summary
In this role, you will develop automated refactoring pipelines for Sonar's codebase, including evaluating, reviewing, and optimizing agents for efficient migrations.
Job Technologies
Your role in the team
- As an Agentic Software Engineer on the Platform Architecture squad, you will build the multi-agent systems that autonomously refactor and modernize Sonar's own codebase - starting with one of our biggest technical bets: unifying SonarQube Cloud (SQC) and SonarQube Server (SQS) onto a single, portable architecture ("build once, deploy twice"). You will:
- Design and build agentic refactoring pipelines that can safely extract a domain's logic from our existing SQS/SQC codebases and re-platform it onto our Unified Core (a hexagonal "capability-core + adapters" architecture), with minimal human oversight.
- Define the guardrails that make autonomous refactoring safe at scale - verification gates, automated test generation, static analysis, and rollback strategies that let agents move fast without breaking production code relied on by 7M+ developers.
- Prove the approach on real migrations - Micronaut-to-Spring conversions, Lambda-to-container consolidations, API convergence (consolidating overlapping API surfaces onto shared contracts), and strangler-fig domain extractions - before scaling it into a repeatable, multi-agent "coding squad" capable of tackling many domains in parallel.
- Bleiben Sie regelmäßig in der Java/Spring-Codebasis aktiv, um kritisch zu überprüfen, was die Agenten produzieren, um zu erkennen, wann eine Refaktorisierung architektonisch falsch ist, und um die agentische Schleife zu korrigieren, die sie erzeugt hat – nicht nur die Ausgabe.
- Spend the majority of your time (roughly 70%) designing, building, and iterating on agentic tooling: orchestration, tool-use, context management, and evaluation harnesses for autonomous code-modification agents.
- Build and refine the verification layer that gates what agents are allowed to ship - automated test generation, regression detection, static analysis (using our own SonarQube), and human-in-the-loop checkpoints where warranted.
- Spend the remainder of your time (roughly 30%) hands-on in our Java/Spring codebase: reviewing agent-generated pull requests, fixing what they get wrong, and feeding those lessons back into the tooling.
- Partner closely with the Server, Cloud Platform, and value-stream squads whose domains you're migrating - earning their trust and buy-in matters as much as the code itself.
- Contribute to the Architecture Decision Records (ADRs) and standards that govern how our platform evolves.
- Track and evaluate emerging agent frameworks and techniques, bringing back what's genuinely useful - as distinct from what's just hype - for accelerating engineering across Sonar.

Our expectations of you
Qualifications
- Strong software engineering fundamentals in Java and Spring (or a comparable JVM/enterprise stack) - enough to read a large, mature codebase critically and tell good architecture from bad.
- A track record of owning complex, ambiguous technical problems independently and driving them to resolution - this is an R&D-flavored role inside a production platform team, and you'll be shaping the playbook, not following one.
Experience
- Hands-on experience building or operating multi-agent or LLM-agent systems in a real production setting - not just prompting a coding assistant, but designing the orchestration, tool-use, and guardrails around autonomous agents.
- Experience building evaluation or verification systems for AI-generated changes: automated testing, static analysis, regression detection, or comparable safety nets for code you didn't personally write.
- Experience influencing engineers and squads you don't manage - the migrations you'll enable depend on their trust as much as on your code.
