JavaScript/TypeScript Software Engineer - Static Code Analysis

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 Sonar Code Quality Team is seeking a passionate and innovative Software Engineer to join our team.
* 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.

• The Impact You Will Have:
• Our team’s mission is to design and implement advanced solutions that automatically identify and prevent critical issues in source code, whether written by developers or generated by AI agents.
• This role provides the opportunity to leverage your expertise in static analysis in an innovative environment—driving the integration of Artificial Intelligence (AI) and Large Language Model (LLM) techniques within a context closely connected to applied research.
• As a software engineer on the team you will work at the intersection of cutting-edge technologies and programming language semantics, enabling us to detect complex issues that often escape both human review and automated systems.
• What You Will Do Daily:
• Contribute to End-to-End Delivery: Collaborate with Product Managers, engineering teams, and research teams to specify and implement sophisticated code analysis and bug detection capabilities in our products. This includes scoping specifications, writing robust code and tests, conducting peer reviews, validating new features, and acting on user feedback post-release.
• Deep Dive into Language: Regularly explore the intricacies of programming language semantics, advancing our knowledge and enhancing our programming languages analyzers.
• Evolve Analyzer Intelligence: Influence how our analyzers interpret code by developing improved models and innovative new rules, enhancing the precision of our code detection capabilities.
• Contribute to Strategic Goals: Engage with various stakeholders to actively contribute to short-term objectives and long-term strategic vision for your squad.

• 2+ years of JavaScript / TypeScript development experience.
• Strong engineering skills and deep understanding of Computer Science fundamentals.
• Proven grasp of static analysis techniques preferred, as applied to challenging code analysis and bug detection problems.
• Interest in leading initiatives is a plus, including planning, task delegation, pull request reviews, and mentorship.
• Experience or curiosity about Large Language Models (LLMs), Machine Learning (ML), and Artificial Intelligence (AI) is highly valued.
• Ability to learn quickly.
• Open-minded and positive can-do attitude.
• Comfortable dealing with change and complexity.
• Knowledge of static code analysis is not required; you will learn it while working at SonarSource. Candidates to be considered must be located near our Geneva or Bochum offices or open to relocating prior to starting.
