Sonar is the trust and verification layer for AI code, and the industry standard for automated code review.

The Role

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:

As a member of one of our engineering squads, you will leverage your experience and expertise to design and develop Cloud-based solutions and migrate existing applications to Cloud-native ones. This means implementing massively scalable services, automating all system operations, measuring and continuously improving service quality, and making the lives of other developers easier.

You will play a key role in helping our product reach its next stage of evolution and delight our users and customers.

As part of the role, you will participate in an on-call rotation to provide timely support and address any critical system issues that may arise outside of regular working hours.

What You Will Do Daily:

Develop, enhance, and operate cloud solutions on AWS with a focus on automation, high performance, scalability, and cost-efficiency.
Take part in the definition of novel cloud solution designs and lead their development.
Work in sprints with other engineers (backend, frontend, SRE, and other CPEs) as part of a cross-functional team to deliver new features into production.
Collaborate with other squads in Product Development and Mission Control (InfraSec, IST) to ensure solutions fit into the Sonar platform.
Contribute to your squad’s efforts in the investigation of alarms, SLOs, and incidents to maintain a high quality of service.

The Experience You Will Need:

3+ years of experience with architecting, developing, and operating cloud solutions on AWS.
In-depth knowledge of AWS networking and the following AWS services: CloudFront, CloudWatch, Lambda, EC2, ECS, SNS, SQS, and RDS.
Advanced proficiency in Infrastructure as Code (IaC) with at least one of the following tools: AWS CloudFormation, AWS CDK (preferred), or Terraform.
Experience with at least one programming language such as Python, Java, C# or similar.
Experience with at least one scripting language such as Bash or similar.
Strong DevOps mindset.
Experience working in an agile environment.
Self-confident enough to challenge the status quo as well as to give and receive feedback.

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.

Sonar

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. Integrating code quality and code security into a single platform (SonarQube), Sonar delivers deterministic, repeatable, and actionable code verification at scale, analyzing over 750 billion lines of code daily to ensure software is secure, reliable, and maintainable.

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 worldwide, including Snowflake, Booking.com, Deutsche Bank, AstraZeneca, and Ford Motor Company.

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

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

Why Work With Us

We are a product-first company, with a people-first culture. Every employee has the opportunity to grow and learn. We promote from within, provide regular feedback and professional development opportunities, value the right to fail along with respect and kindness and work with team members to achieve their full potential.
