Senior Software Engineer (Java)

Why should I Apply:

At Sonar, we’re a group of brilliant, motivated, and driven professionals working hard to help organizations build responsible, secure, high-quality code quickly and systematically. We build solutions that don’t just solve symptoms of problems – we fix problems at the source – source code, to be specific.

We have a dynamic culture with employees worldwide and hub offices in the USA, Switzerland, the UK, Singapore, and Germany. We believe team members should have the opportunity 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: provide solutions that deliver Clean Code.

The Impact you can have

Join us in shaping the future of SonarQube and empower over 10 million developers worldwide to write cleaner, more secure code. As a Senior Software Engineer in our Identity squad, you will build scalable, security-critical services that seamlessly integrate SonarQube with the leading DevOps platforms.

You will operate in a fast-paced, high-impact environment, contributing to both cloud-native services and on-premises solutions. Your work enhances authentication, authorization, and platform security—key areas relied upon by our open-source community of over 500,000 members and tens of thousands of corporate customers, including NASA, Novartis, Ubisoft, and Microsoft.

Based in Geneva, Switzerland, you will join an interdisciplinary squad of software engineers, product managers, and UX designers. You will collaborate with highly skilled engineers who simplify the complexity of Identity and Access Management (IAM) while ensuring seamless integration for our customers. As a senior engineer, you will drive architectural decisions across squads, balancing short-term priorities with long-term scalability. If you thrive on impact, ownership, and technical excellence, we want you on our team.

On a daily basis, you will

• Develop secure, scalable Identity and Access Management (IAM) services for SonarQube Cloud, our SaaS platform, and SonarQube Server, our on-premises software.
• Write clean, maintainable code, deploy features to our SaaS platform, and ensure predictable release cycles for on-premises users.
• Drive architectural evolution and technical excellence for our cloud-native services and our on-premises offering.
• Support engineers through mentorship, technical leadership, and fostering a culture of learning and autonomy.
• Diagnose and resolve production issues, improve platform stability, and participate in on-call rotations for critical incidents.

The technical skills you will demonstrate

• Strong Java development skills with 6+ years of experience writing clean, maintainable, and scalable code.
• Experience designing and implementing cloud-native applications on AWS is a plus.
• Deep understanding of system architecture, design patterns, and performance optimization.
• Experience with databases (e.g., PostgreSQL) and writing efficient SQL queries.
• Commitment to code quality, with hands-on experience in automated testing and CI/CD practices.
• Growth mindset and experience in mentoring, coaching, and elevating your teammates.
• Proactive problem-solving attitude, taking ownership of initiatives and driving them to completion.

The soft skills you will demonstrate

• You take full responsibility for complex challenges, driving solutions from inception to production and validating them with customer feedback.
• You thrive in a fast-paced, dynamic environment, tackling complexity with a structured and solution-oriented mindset.
• You validate assumptions, establish facts to guide better decisions, and proactively seek and provide feedback for growth.
• You tailor your message to your audience, inspire commitment, prioritize impact, and drive efficiency in collaboration.

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!). We believe that the best idea wins and everyone has a voice.

• We believe that great people make a great company. We value people skills as much as technical skills and strive to keep things friendly and laid-back while still being passionate leaders in our domains. Our 550+ SonarSourcers from 33 different nationalities can relate!

• We embrace work-life balance. It is important to maintain a healthy work-life balance. This is why we have a flexible work policy that includes remote and in-office hybrid work (minimum three days a week in the office - Monday/Tuesday/Thursday).

• We have a growth mindset. We love to learn and believe that continuous education is critical to our success. In an ever-changing industry, new skills are a must, and we're happy to help our team acquire them.
