Job Summary:
WHOOP is on a mission to unlock human performance and healthspan through wearable technology and digital experiences. The Senior Software Engineer on the Growth team will lead the technical direction of web experiences, focusing on user acquisition, engagement, and retention, while mentoring engineers and driving cross-functional initiatives.
Responsibilities:
• Own the architecture and technical direction of WHOOP's web experiences, including our Next.js-based join flow, Cloudflare Workers edge infrastructure, and Stripe-powered checkout
• Lead cross-functional projects end-to-end from brainstorm and technical planning through implementation, QA, rollout, and post-launch analysis, partnering closely with Product, Design, and Analytics
• Design and execute experiments (A/B tests) with rigor, ensuring proper instrumentation, measurement, and iteration based on impact to North Star metrics
• Drive frontend performance, accessibility, and reliability across devices and browsers, establishing standards and monitoring that the team can build on
• Write clean, well-tested, production-quality code in TypeScript/React/Next.js and integrate deeply with backend services, payment systems (Stripe), and ecommerce platforms (CommerceTools)
• Author and review technical plans, identify architectural tradeoffs, and make sound judgment calls that balance speed with long-term maintainability
• Mentor and develop other engineers through code review, pairing, and technical guidance, raising the bar for quality and velocity across the web surface
• Participate in on-call rotations and incident response; lead postmortems and drive improvements that prevent recurrence
• Contribute to Growth's engineering culture through documentation, process improvements, and knowledge sharing
Qualifications:
Required:
• 5+ years of professional experience in frontend software engineering, with deep expertise in TypeScript, React, and modern web frameworks (Next.js strongly preferred)
• Track record of owning and delivering complex, cross-functional web projects from technical design through production rollout
• Strong understanding of web performance optimization, edge computing (e.g., Cloudflare Workers), and responsive design at scale
• Experience integrating frontend applications with payment systems (Stripe preferred), RESTful APIs, and third-party platforms
• Demonstrated ability to design and run meaningful A/B tests and make data-informed decisions in a growth or product engineering context
• Experience with observability and monitoring tools (e.g., Datadog, Sentry, Amplitude) to proactively identify and resolve production issues
• Proven ability to mentor engineers, lead technical discussions, and influence engineering practices across a team
• Excellent written and verbal communication skills; comfortable operating in an async-first, cross-functional environment
Preferred:
• Experience with ecommerce platforms (CommerceTools), feature flag / experimentation infrastructure, or subscription/membership business models
