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.

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

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 Semantics: 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 and intelligence 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.

The Experience You Will Need:

• 2+ years of Java 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.
• Familiarity with Python language and ecosystem is also appreciated, but not required.
• 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.

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.
