About the Role:

We’re looking for a Senior or Staff Growth Platform Engineer to build and operate the systems that power lifecycle messaging and in-product growth experimentation across Quizlet.

• Improve the feedback loop between experiment results, user behavior signals, and product decisions

What you bring to the table:

• Strong backend or platform engineering experience building reliable, scalable systems
• Experience with notification systems, messaging infrastructure, or lifecycle platforms
• Experience supporting product experimentation, feature flags, or A/B testing systems
• Familiarity with event-driven systems, queues, APIs, and service reliability
• Strong judgment around user experience, notification quality, privacy, and guardrails
• Ability to work cross-functionally with Product, Data, and Engineering teams
• Comfort operating in a fast-moving environment where speed and reliability both matter

Bonus points if you have:

• Experience with email or push delivery systems
• Experience with Braze or similar lifecycle messaging platforms
• Experience with feature flag systems or experimentation frameworks
• Familiarity with user targeting, audience logic, or growth analytics
• Experience building internal tooling for operators or product teams
