Job Description

Who is Sonar?
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. Today, Sonar is used by +7M developers and 400K organizations worldwide, including the DoD, Microsoft, NASA, MasterCard, Siemens, and T-Mobile.
We believe in developing great products that are supported by great internal teams and a strong culture. We are highly committed to and obsessed with the company, users, each other, and our open source community. We have high standards and hold each other accountable for acting with positivity, dedication, thoughtfulness, empathy, and passion daily.
We are deliberate with our decisions with high clarity of intention. At the same time, we feel extreme urgency and move forward quickly.
And lastly, we are highly effective and operationally efficient We operate collectively as One Team to accomplish our goals.
At Sonar, CODE is more than just an acronym – it's a mindset that defines daily operations.
Why You Should Apply:
At Sonar, we’re a group of brilliant, motivated, and driven professionals working hard to help supercharge developers to build better, faster. Sonar helps to continuously improve code quality and code security while reducing developer toil. This means that developers can focus on doing more of what they love and less of what they don’t. 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.
We have a dynamic culture with employees worldwide and hub offices in the USA, Switzerland, the UK, Singapore, and Germany. Team members should be able to come to work every day, work on a product they are proud of, love what they do, and feel energized by their peers. With our roots deep in the open source community, we’re all about the mission: supercharge developers to build better, faster.
The Impact You Will Have:
At Sonar, we are the gateway between our products and the entire developer ecosystem. 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.

What You Will Do Daily:

• Deliver Features on the Integration Core. You will implement well-scoped backend features that keep our DevOps Platform integrations reliable and extensible — repository importing, binding, authentication, and webhook processing.
• Own Your Code from Local to Cloud. You will write clean, testable Java code and own your work from local development to production. You are responsible for the full lifecycle of the features you build. You will deploy to AWS, monitor service health through metrics and logs, and troubleshoot production issues to maintain high availability for our users.
• Enable Other Squads. You will contribute to the libraries and APIs that other engineering teams use to interact with DevOps platforms. Small improvements here have a multiplying effect across the organization.
• Contribute to Agentic Workflow Features. 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.
• AI-Native Engineering. Use AI assistants pragmatically to speed up low-level tasks (boilerplate, refactorings, test scaffolding) while keeping full responsibility for architecture and quality.
• Collaborate & Grow. You will review PRs, write documentation, and participate in design discussions. You will learn from staff engineers on the squad and contribute your own perspective as you build expertise in your domain.

The Experience You Will Need:

• Solid Backend Engineering (3+ years). You have a track record of building and maintaining backend systems. You write clean, testable code and care about getting the details right.

• Java Proficiency. Java is our primary language. You are comfortable with the Java ecosystem and can navigate a large, established codebase effectively.

• Cloud or Distributed Systems Fundamentals. You understand how services communicate in a distributed environment — REST APIs, message queues, async processing. You have hands-on experience with AWS (or equivalent cloud platforms) and are comfortable with deployment, logging, and observability basics.

• Ownership Mindset. You don't just "take tickets." You own the delivery of your tasks, raise risks early, and ensure your work meets high quality standards before it reaches production.

• Curiosity About AI and Agentic Systems. 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.

How You Work

• Ownership and accountability: You feel responsible for the long-term health and correctness of what you ship, whether written by you or generated with AI assistance.
• Collaborative by default: You communicate with clarity, seek alignment early, and view candid feedback as a tool for growth.
• AI-native mindset: 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.
• Pragmatic and incremental: You balance architectural excellence with the need to deliver value quickly and iteratively.

Our Technical Stack

• Languages: Java (Primary), Python (AWS CDK), TypeScript (integrations, frontend)
• Infrastructure: AWS (Lambda, ECS, API Gateway, SQS, RDS etc), Docker
• Integrations: GitHub, GitLab, Bitbucket, Azure DevOps, Jira, Slack
• Principles: Pragmatic code, SOLID, TDD, distributed systems

Why You Will Love It Here:

• Our culture and mission set us apart. We have a dynamic work culture that values respect and kindness and embraces the right to fail (and get right back up again!).
• Great people make a great company. We value people skills as much as technical skills and strive to keep things friendly while still being passionate leaders in our domains.
• We have a flexible work policy that includes 3 days in-office and 2 days work-from-home each week for those located near our office locations; some locations such as Dubai, India, Japan and Australia operate fully remotely.
• We have a growth mindset. We love learning and believe continuous education is critical to our success. In an ever-changing industry, new skills are necessary, and we're happy to help our team acquire them.
• As the leader in our field, our products and services are as strong as our internal team members.
• We embrace transparency with regular meetings, cascading messages and updates on the growth and success of our organization.

Benefits of Working With Sonar - Geneva:

• We encourage usage of our robust time-off allocations with 27 PTO days for our employees based out of the Geneva region, plus additional days based on seniority and circumstances.
