Senior Platform Engineer

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 Engineering Experience squad accelerates developer productivity across the Sonar supply chain by providing a secure, reliable, performant, and standardized development ecosystem. Our goal is to empower teams to build and release with confidence, enabling them to focus on delivering exceptional products.

What We Do

We own and operate the critical infrastructure that fuels Sonar’s development lifecycle, including:

• Source Code Management – Maintaining and securing our GitHub presence through Infrastructure as Code.

• Continuous Integration – Managing self-hosted CI infrastructure in AWS for image creation and job execution.

•  Release Validation – Ensuring artifact integrity and quality through comprehensive release checks.

•  Release Management – Streamlining artifact promotion and release orchestration via JFrog integration.

•  Secrets Management – Providing secure authentication and authorization for CI infrastructure and tools using Hashicorp Vault.

•  Dependency Management – Automating updates and security patching with Renovate.

•  GitHub Actions Platform – Delivering a scalable, reliable self-hosted environment for GitHub Actions in AWS.

•  Developer Self-Service – Enabling developer autonomy through our internal developer portal for key operations.

The impact you will have  

As a Platform Engineer, you will be a key player in evolving Sonar’s engineering experience. You will design, build, and maintain the core CI/CD pipelines and developer tooling that drive our development process. You’ll work closely with engineering teams to enhance automation, security, and developer productivity, while advocating for best practices and optimizing key developer experience metrics.

On a daily basis, you will

• Own and enhance our CI/CD pipelines, ensuring they are scalable, secure, and efficient.
• Empower developers with self-service tools, reducing friction in the development process.
• Measure and improve developer experience using data-driven insights and key performance metrics.
• Advocate and educate, showcasing demos and best practices to keep teams informed.
• Secure the software supply chain, ensuring industry standard compliance and reducing security risks.
• Automate infrastructure and pipeline configurations to reduce drift and improve reliability.
• Collaborate with teams to establish standardized deployment and release processes.
• Scale and optimize Sonar’s AWS Infrastructure: Self-hosted runners, CI tooling, and secrets management.
• Lead cross-team collaboration, driving initiatives that improve engineering workflows.

The technical skills you will demonstrate

• Strong experience in DevOps, CI/CD, and automation in cloud environments.
• Strong programming skills in both statically typed (e.g., Java) and dynamically typed (e.g., Python) languages, complemented by expertise in Shell scripting (e.g., Bash).
• Deep knowledge of AWS, HashiCorp Terraform, and AWS CDK.
• Hands-on experience with GitHub, GitHub Actions, and build tools (Maven, Gradle, NPM, Yarn, MSBuild…).
• Expertise in containerization technologies, including Docker, Kubernetes, and EKS.
• Strong experience in Infrastructure as Code (IaC), Configuration as Code (CaC), and Everything as Code principles.
• Security-first mindset, with experience in securing CI/CD pipelines and secrets management.
• Experience with monitoring and observability tools such as Datadog.
• Bonus: Experience with Sonar products and Renovate.

The soft skills you will demonstrate

• Autonomous, pragmatic, and results-driven, with a focus on execution.
• Strong leadership and collaboration skills, driving engineering-wide initiatives.
• Effective communicator, engaging with developers and stakeholders to drive adoption.
• Open-minded and adaptable, comfortable navigating complexity and change.
• Challenger of the status quo, continuously improving processes and tooling.
• Bias toward action, prioritizing progress over perfection.

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.
