Who is Sonar?

Sonar enables organizations to ship agentic code with confidence. Code creation is abundant, but confidence is scarce. Our core platform, SonarQube, verifies over 750 billion lines of code every day, delivering agentic verification and governance for all code. Trusted by more than 7 million developers and 75% of the Fortune 100, including teams at Nvidia, ServiceNow, Booking.com, Goldman Sachs, AstraZeneca, and Ford Motor Company, Sonar enables organizations to reduce outages, improve security, and lower the cost and risk of agentic software development.

Founded in Geneva and now headquartered in Austin, Texas, Sonar has a global team working across offices and hubs, including Silicon Valley, London, Bochum, Barcelona, Singapore, Tokyo, and the Washington, D.C. area. At Sonar, we’re enabling enterprises to build agentic software factories that can move quickly while maintaining the control, consistency and evidence required to ship with confidence.

Position description

Sonar's website is becoming a bigger driver of pipeline as our Web team scales, and we need someone focused full-time on turning traffic into qualified demand. As Website Conversion & Optimization Manager, you own the site's CRO and testing program end to end: hypotheses, test design, QA, launch, and analysis, plus the broader analytics and organic and content signals that feed it, working directly with our VP, Digital & Web. This is a hands-on role: with no dedicated testing team under you, you'll run experiments yourself as often as you'll direct them, partnering with our SEO Strategist, Lead Web Producer, and engineering team to keep every page fast, findable, and built to convert, and directing outside optimization and testing agency partners rather than building or managing an internal team.

What you will do

Own conversion rate optimization across landing pages, calls-to-action, form flows, and on-site conversational engagement (Qualified), from hypothesis through shipped change.

Own the CRO and testing program end to end: write hypotheses, design and configure A/B and multivariate tests, QA them before launch, monitor them live, and analyze results, partnering with the Lead Web Producer on production support and with Engineering on technical implementation.

Connect individual tests into a cohesive test-and-learn roadmap, sequencing experiments so each one builds on prior results instead of running in isolation.

Own web analytics (GA4 and Mixpanel) and marketing conversion signals, including tracking, attribution, and form and CTA performance, turning data into a prioritized optimization roadmap.

Bring working SEO knowledge to the optimization program, coordinating with the SEO Strategist so technical SEO and conversion work are aligned rather than working at cross purposes on the same pages.

Brief, direct, and review the output of outside optimization and testing agency partners, holding contracted resources accountable to scope, quality, and deadlines.

Drive organic initiatives, including PR, earned media, backlinks, infographics, and influencer organic, in partnership with Corporate Marketing.

Coordinate short-form organic content, such as social posts and short video, with the Social Media team.

Report on experiment results and conversion performance, and communicate the rationale behind test prioritization and roadmap tradeoffs, to the VP, Digital & Web and cross-functional stakeholders in clear, decision-ready terms.

Experience and qualifications

The ideal candidate will

Have 4+ years of experience in conversion rate optimization, growth marketing, or web optimization, ideally at a B2B SaaS company.

Have hands-on experience owning A/B and multivariate tests end to end, from hypothesis and test build through QA, launch monitoring, statistical analysis, and rollout, not just designing or interpreting tests someone else runs.

Be comfortable operating without a dedicated testing team or engineering support on standby, running and troubleshooting experiments directly when needed.

In-office culture

We're intentional about this. We believe the best teams are built in the room together. Three anchor days — Mondays, Tuesdays, and Thursdays — create the collaboration rhythm that makes a hub office worth having.

Candidates need to be genuinely based in the location the role is posted — if that's not where you are today, we're happy to support relocation for the right person.

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.

If you need any accommodation, please reach out to us at hiring@sonarsource.com.

All offers of employment at Sonar are contingent upon the results of a comprehensive background check and reference verification conducted before the start date.
