Sonar helps prevent code quality and code security issues from reaching production, amplifies developers' productivity in concert with AI assistants, and improves the developer experience with streamlined workflows. Sonar analyzes all code, regardless of who writes it — your internal team, genAI, or third parties — resulting in more secure, reliable, and maintainable applications. Rooted in the open source community, Sonar’s solutions support over 30 programming languages, frameworks, and infrastructure technologies. We believe in developing great products that are supported by great internal teams and a strong culture. At Sonar, CODE is more than just an acronym – it's a mindset that defines daily operations.
Our solutions don’t just solve symptoms of problems – we help fix issues at the source – for all code, whether it's developer-written, AI-generated, or from third parties.
Our squad owns the "connective tissue" that over 400,000 organizations rely on to weave Sonar into their daily development lifecycle — deep integrations with DevOps platforms (GitHub, GitLab, Bitbucket, Azure DevOps) and a growing suite of third-party applications such as Jira and Slack.
We are entering a transformative era: the shift toward an Agentic SDLC, where AI agents and humans collaborate seamlessly to build better software. As a Software Engineer on this squad, you will help keep our high-scale integration infrastructure reliable and evolving, while beginning to explore how these same connective systems will serve the next generation of AI-driven workflows.
You will implement well-scoped backend features that keep our DevOps Platform integrations reliable and extensible — repository importing, binding, authentication, and webhook processing.
You will write clean, testable Java code and own your work from local development to production. You will contribute to the libraries and APIs that other engineering teams use to interact with DevOps platforms. As the squad expands its integration surface to serve AI agents, you will contribute to these new capabilities — helping build and test the connectors and APIs that allow agents to consume Sonar context and act within DevOps platforms, building practical experience with emerging patterns like MCP.
Solid Backend Engineering (3+ years). Java Proficiency. Java is our primary language. You are comfortable with the Java ecosystem and can navigate a large, established codebase effectively.
You have hands-on experience with AWS (or equivalent cloud platforms) and are comfortable with deployment, logging, and observability basics.
You own the delivery of your tasks, raise risks early, and ensure your work meets high quality standards before it reaches production.
You are excited about where software development is heading. Experience with LLM APIs (OpenAI, Anthropic) is a plus, but genuine curiosity and a willingness to learn is what matters here.
You treat AI tools as collaborators — not oracles — validating their output, understanding their limits, and using them to focus on higher-value design and problem-solving.
