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:

The primary goal of the Information Security team is to build trust with our rapidly growing customer base by ensuring the security of our products and platform, while demonstrating that our organization meets stringent security standards.

As a member of the team, you will work with engineering teams to ensure products and cloud platforms are designed, built, and maintained to Sonar’s high security standards and assist them through constant improvement. You will also ensure endpoints are fully secure and meet our engineers' needs while procuring and deploying new solutions. You will also investigate and resolve security issues raised with our team. As part of a team-based organization, your contributions will significantly impact the growth of our business through Sonar’s “collective intelligence” mindset.

What You Will Do Daily:

Collaborate with product engineering teams to design and implement secure solutions.
Review product architectures and solutions to ensure integration of security requirements.
Review cloud configuration and perform code reviews.
Develop and implement security initiatives delivered through the strategic security plan.
Procure, design, and implement new security tools or features.
Conduct internal and external security reviews, pen testing, and red team exercises.
Investigate and resolve security issues detected in products and internal systems.
Investigate and manage customer security concerns.
Act as a security SME for security incidents
Review threat intelligence findings and analyse threat landscapes.

The Experience You Will Need:

Extensive experience with cloud architectures, primarily AWS.
Extensive experience with application security assessments including authN and authZ.
Extensive experience with pen testing, red team engagements and bug bounty programs.
Experience with vulnerability investigation and management.
Experience with AI Security.
Experience with threat modeling using frameworks like STRIDE.
Experience with cloud network and firewall policy management.
Experience with coding and scripting such as python, bash.
Familiarity with Azure and GCP platforms, and Google Workspace are a plus.

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.

The Company

Year Founded: 2008

What We Do

Sonar provides the essential verification layer for the AI-driven development era, ensuring all code—whether human-written or AI-generated—is code you can trust.

Today, AI coding tools are generating explosive volumes of code. This has created an "engineering productivity paradox" : faster code writing doesn't automatically lead to faster, safer software delivery. The new bottleneck is verification.

Sonar solves this. Our industry-leading platform, SonarQube, integrates code quality and code security analysis directly into the development workflow by automating reviews and providing actionable code intelligence for all code—first-party, AI-generated, third-party open source. \

For organizations, Sonar provides the critical SDLC governance and compliance reporting needed to de-risk AI adoption and manage standards at scale. We empower teams to "vibe, then verify" — innovating at the speed of AI without sacrificing the quality, security, or maintainability of their codebase.

We are driven by a deep belief in our people, a commitment to excellence, and an unwavering dedication to delivery. We operate as a united group where our collective success is the sum of each individual's contributions. Our company culture is driven by the values of CODE: Committed, Obsessed, Deliberate & Effective. This mindset reflects our culture of creativity, collaboration, and pride in the work we do.

Rooted in the open source community, Sonar’s solutions support over 35 programming languages, frameworks, and infrastructure technologies. Today, Sonar is used by 7M+ developers and 400K organizations worldwide, including Barclays, MasterCard, and T-Mobile.

Sonar is headquartered in Geneva, Switzerland with additional offices in Austin, Texas; Annecy, France; Bochum, Germany; London, England; and Singapore. The company is rapidly growing with over 750 employees!

Join us in our mission to solve the trillion-dollar challenge of bad code!

We are a product-first company, with a people-first culture. Every employee has the opportunity to grow and learn.
