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 trusted by +7M developers worldwide, including teams at 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:

You will support the Tax team in maintaining accurate and timely global tax compliance and tax accounting, supporting indirect tax and withholding tax processes across multiple jurisdictions, strengthening documentation, controls, and operational efficiency as the company grows. Your work will help ensure data accuracy, reduce operational risk, and improve visibility into tax positions. This is a flexible opportunity designed to fit around your academic schedule, with part-time hours during the school year and a full-time commitment over the summer. You'll gain hands-on experience working alongside seasoned tax professionals, supporting a variety of tax compliance and research activities in a fast-paced environment.

What You Will Be Doing:

Support tax compliance by helping gather data and prepare working papers for U.S. federal and state income tax returns (supporting schedules, data pulls, reconciliations), and non-U.S. income tax and local filings (data collection, tracking of deadlines, status updates).
Assist with indirect tax (e.g., sales and use tax, VAT/GST) by preparing or reviewing basic reconciliations between systems (ERP, tax tools, returns) and supporting registration, filing calendars, and documentation requests.
Assist with responding to requests sent to the Tax team from internal business partners as well as external parties including customers and tax auditors
Support tax accounting and provision activities by assisting in preparing schedules for quarterly and annual tax provision and helping reconcile tax-related balance sheet accounts.
Documentation and research, maintaining and organizing tax files, trackers, and process documentation, performing targeted research on tax topics and summarizing findings.
Respond to tax notices and assist with audit support under the guidance of the manager.
Participate in team meetings, training sessions, and professional development activities.
Perform other tax-related duties and special projects as assigned.

The Experience You Will Need:

Currently enrolled in an accredited college or university pursuing a degree in Accounting, Finance, or a related field
Strong analytical and problem-solving skills
High attention to detail and commitment to accuracy
Proficiency in Microsoft Excel or Google Sheets (formulas, lookups, pivots, and basic data analysis)
Strong written and verbal communication skills
Foundational understanding of accounting
Curiosity and a problem-solving mindset, with a willingness to ask questions and explore how things work
Experience with using AI tools (e.g., Gemini, Claude) is a plus

Why You'll 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.

We Value Diversity, Equity, and Inclusion:

At Sonar, we believe that our diversity is our strength. We are a global company that values and respects different backgrounds, perspectives, and cultures.

We are committed to fostering a diverse and inclusive work environment where everyone feels valued and empowered to contribute their best. We are proud to be an equal opportunity employer and welcome all qualified applicants, regardless of race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.

The Company

HQ: Geneva

800 Employees

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. 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!
