Senior Backend Engineer, Growth - Clubhouse

About Clubhouse & Alpha

Alpha is a product studio focused on the intersection of AI and consumer social, well-funded by a16z and top investors. Our flagship product, Clubhouse, pioneered social audio and has created meaningful connections in over 200 countries.

We have a lean, high-impact, high-ownership team. We are 100% remote, founder-led, and product-driven—with a huge, ambitious vision and the right team to make it happen.

The Role

We’re hiring a Senior Backend Engineer (IC4) for our Growth squad on Clubhouse. Our mission is to get people into a room with their friends through more new users, more returning users, and more first connections. We get there through fast experiments across invites, notifications, onboarding, reactivation, and ranking. You’ll ship your first experiment within your first month.

You’ll work closely with our founders, product, design, and data science teams. This role is open to candidates across the U.S.

Who You Are

• Experienced and curious: 4+ years of production backend experience in Python (or similar) with relational and NoSQL databases (PostgreSQL, DynamoDB). Comfortable working in a mature codebase and improving it as you go.
• Built growth systems: Shipped notification targeting, invites, onboarding, or reactivation flows for a consumer product.
• Product mindset: Tie backend work to growth and engagement metrics and bring your own experiment ideas. Balance technical decisions with product outcomes.
• Move quickly and iterate: Scope small MVPs, ship them behind a flag, and read the results. Understand exposure logging, guardrail metrics, and balance speed with reliability.
• Work well cross-functionally: Enjoy partnering closely with Product Managers, Designers, and Data Scientists to shape hypotheses and act on results. Communicate tradeoffs clearly in writing.
• Collaborative and low-ego: Evolve thinking based on new data, seek the best solution regardless of ownership, and contribute to an inclusive culture.
• Build with AI: Use AI coding tools every day and keep PRs small enough to review quickly.

What You Will Do

• Build and ship experiments across invites, notifications, onboarding, reactivation, and ranking reaching millions of users.
• Evolve backend systems balancing quick iteration with code health and scalability.
• Collaborate closely with engineers, PMs, designers, and data scientists to deliver high-impact features.
• Instrument and analyze experiments to inform the next iteration.
• Advocate for simplicity and make thoughtful tradeoffs to ensure solutions are maintainable and measurable.
• Own the experiment loop, making tests faster to set up and safer to run with clear guardrails.
• Create something meaningful that brings people's voices together globally.
