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.Â
We are deliberate with our decisions with high clarity of intention. At the same time, we feel extreme urgency and move forward quickly.Â
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.Â
Why You Should Apply:Â
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.
What You Will Do Daily:
•
Design, Build & Maintain Integrated Internal Applications
•
Own the end-to-end lifecycle of internal software applications and integrations: architecture, coding, testing, deployment, and maintenance.
•
Translate business requirements into robust, scalable technical designs, including data models, APIs, system architecture, and UI flows where relevant.
•
Implement full-stack features: write clean, efficient, and maintainable code for both back-end and front-end components; design and manage persistence layers; integrate with third‑party APIs (e.g., Salesforce, Stripe) and internal services.
•
Build security & compliance into the design, incorporating data protection and regulatory requirements (e.g., GDPR) from the start, and collaborating with IST, ITOps, and Legal to ensure adherence to standards.
•
Act as a Technical Partner to Business Stakeholders
•
Collaborate with business stakeholders (e.g., Finance, Sales, HR, Business Technology colleagues) to clarify requirements, challenge assumptions, and co‑design pragmatic, value‑driven solutions.
•
Support and guide User Acceptance Testing (UAT): provide technical support during UAT, address defects quickly, and ensure the delivered solution truly solves the underlying business problem.
•
Communicate clearly on feasibility, trade‑offs, and timelines, serving as the technical point of contact and managing scope to protect solution integrity and production stability.
•
Own the Full Development & Operational Lifecycle
•
Implement and operate CI/CD pipelines to achieve reliable, frequent releases with a low change‑failure rate.
•
Write and maintain unit, integration, and end‑to‑end tests to ensure high software quality and reduce regressions.
•
Provide ongoing production support for the applications you own, including bug fixes, performance tuning, refactoring to address technical debt, and planned feature evolution based on user feedback and strategy.
•
Document architecture and decisions clearly (e.g., in Confluence/Xtranet and Atlas), so the broader team can understand, operate, and extend your work.
•
Ensure System Health, Monitoring & Incident Response
•
Implement comprehensive monitoring and alerting for all owned applications, with meaningful KPIs and dashboards that surface issues before they become incidents.
•
Serve as the primary on‑call engineer (as part of a rotation) for your applications, leading incident investigation and coordinating with other teams when issues occur.
•
Run blameless post‑mortems after critical incidents, identify root causes, and define action items that meaningfully reduce recurrence.
The Experience You Will Need:
•
5+ years (tbc) as a Full-Stack Engineer building business‑critical applications and integrations.
•
Strong proficiency in at least one modern back‑end language (e.g. TypeScript, Java), in AWS environments.
•
Proven experience designing and implementing integrations between SaaS systems (e.g., CRM, billing, payments, licensing, ERP) with robust error handling and observability.
•
Solid understanding of software architecture and design principles, including how to design for scalability, maintainability, and operational robustness over time.
•
Demonstrated ability to build secure and compliant solutions, with an understanding of data protection concepts (e.g., GDPR) and secure coding practices.
•
Hands‑on experience with CI/CD, automated testing, and modern SDLC practices (e.g., Git-based workflows, code reviews, trunk‑based or similar).
•
Familiarity with monitoring, logging, and incident management for production services.
