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

The Role

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

We want to make the best decisions possible for our products and to do that, we need to make data-driven decisions.

To achieve this goal, we are looking for a talented Data Engineer - you! - to join the Data team.

Together, we will make SonarSource’s products the undisputed world-leading code remediation solution!

This means:

Take technical ownership of the data platform and produce high-quality self-served components that the domain teams can use autonomously.
Get involved in the definition of new features and technologies that will impact all SonarSource teams and hundreds of thousands of developers worldwide.
Help improve the team's effectiveness by challenging and continuously improving existing processes, designs, and engineering practices.

On a daily basis you will

Design and develop the data platform to support the functional domains in handling their data by using the state-of-the-art while helping them in their journey to data ownership
Design and implement data retrieval, storage, transformation, and load capabilities following Data Mesh principles.
Continuously enhance the data platform and propose, implement, and manage data handling services according to stakeholders' needs (Product Managers, Marketing, Sales, engineering teams, etc.).
Establish top-class end-to-end pipelines including data cleaning and modelling.
Develop and deploy connectors to data sources of interest.
Assemble large, complex data sets that meet functional / non-functional business requirements.
Maintain evergreen data flow documentation across systems.
Collaborate on Data Governance with other stakeholders/domains.
Implement appropriate entitlement controls around data access.
Work with the security function to ensure we adhere to expected security standards.
Collaborate with the incident manager to bring your expertise when asked and own implementation of recommendations from post-mortems.

The skills you will demonstrate

You have solid software engineering experience, focusing on developing analytics components in the cloud. You have been exposed to big data architecture essentials, streaming, data manipulation using SQL, ETL batches, data store administration, etc.
You see yourself as a developer working on data. You are motivated by both technical and functional aspects of services.
You are a friendly, enthusiastic, and organized team player. You actively share your knowledge and give and receive feedback to improve the team and yourself.
Strong experience building end-to-end ETLT, ETL, or ELT pipelines with batch or streaming technologies in Python.
Strong experience with the AWS platform including, but not limited to, services such as Glue, RedShift, CloudFormation, S3, CloudWatch, Lambdas, etc.… or equivalents
Good knowledge of data engineering concepts (Data Lake, Data Warehouse, etc.)
Experience querying, manipulating, and modeling data with SQL. Knowledge of dbt is a plus.
Experience with Infrastructure as code tools (CDK, CloudFormation, Terraform)
Knowledge of how to use visualization tools such as, but not limited to, Tableau, AWS Insights, or Looker
You are fluent in English, both written and spoken.

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.

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.
