• Drive initiatives that grow our member base to the next level of scale.

• Enhance customer activation flows to ensure a smooth onboarding experience.

• Help members reach their “aha” moment faster through seamless, thoughtful product experiences.

• Work across different parts of the system to create coherent, end-to-end user experiences.

What you'll bring :

• 4+ years of professional working experience in full-stack development with a strong focus on backend systems, and the flexibility to dive into frontend or other areas as needed to move the product forward.

• Proficiency in Python and Postgre

SQL, with solid familiarity in AWS technologies, React, and Next.js.

• Curiosity to explore new technologies, with the ability to thoughtfully leverage AI to enhance product experiences while understanding its limitations.

• A strong sense of urgency and ownership in driving projects from design through execution and support.

• Proven ability to communicate complex technical concepts clearly to stakeholders across diverse functions.

• Hybrid Work Model :
Based in San Francisco with a balance of in-office and remote flexibility
