About the role

Senior role owning Tailscale's website experimentation program across high-traffic pages, setting roadmap and standards, designing and shipping high-stakes tests, coaching others, and ensuring reliable measurement and alignment with web strategy.

Responsibilities

  • Own the experimentation roadmap, from taking in ideas across the team to prioritizing them against traffic, expected impact, and cost.
  • Set and maintain the standards every test runs on, including sizing, statistical power, minimum detectable effect, guardrail metrics, and the rules for shipping, iterating, or stopping a test.
  • Review test designs before launch and results before they're shared, so every number we report is one we can stand behind.
  • Design, build, and run the most consequential experiments yourself, particularly on pricing and the homepage.
  • Own the health of our testing platform and measurement with web development and analytics, so tracking works and results reconcile with our analytics data.
  • Maintain the experiment record as the source of truth for what our website has learned, and turn accumulated results into recommendations for web strategy.
  • Report program results to marketing leadership: what we learned, what shipped, and what we're testing next.
  • Coach contributors across web, design, and marketing on hypothesis quality, test design, and reading results correctly.

Qualifications

  • 6–9 years of experience in conversion optimization, web experimentation, growth marketing, or a related field, including ownership of an experimentation program across multiple pages or products
  • Deep experience with a testing platform such as Optimizely, VWO, or a comparable tool, including program-level setup and governance
  • Strong command of experiment statistics, including power and sample size, minimum detectable effect, false positive control, guardrail metrics, sample ratio mismatch, and the risks of peeking and multiple comparisons
  • The ability to evaluate a test's design and validity, and to explain plainly why a result should or shouldn't be trusted
  • Comfort with HTML, CSS, and JavaScript to build and debug client-side variations yourself
  • Working proficiency in SQL and an analytics tool such as GA4, enough to validate results independently of the testing platform
  • Sound judgment about when an experiment is the right tool, and when a change is low-risk and reversible enough to ship without one
  • Clear writing and communication, with the ability to present results and tradeoffs to senior stakeholders
  • Experience coaching or mentoring others on experimentation, formally or informally
  • Comfort working in a remote-first, async environment
