About the role
We’re looking for a Senior Software Engineer to design, build, and deliver features for acquisition, activation, upgrade/upsell, and retention that are core to Quizlet’s growth. You’ll work closely with other engineers, product managers, designers, and data scientists to turn ideas into scalable, high-quality solutions that serve millions of learners globally.
What they're looking for
- 5+ years of experience in software engineering, ideally in fast-paced, product-focused environments
- Proven ability to deliver complex projects end-to-end - from design and implementation through testing and deployment
- Hands-on experience with experimentation/feature-flagging platforms (GrowthBook, Optimizely, LaunchDarkly, Statsig) — running tests, not just reading dashboards
- Working knowledge of experiment design fundamentals — sample size/power, guardrail metrics, novelty effects, and avoiding false-positive conclusions
- Solid foundation in backend, mobile development or full-stack, with a focus on building scalable, high-quality systems and user experiences
- Comfortable working with event-tracking or analytics data pipelines (e.g., BigQuery, Pub/Sub) to instrument and validate experiments
