Whatnot is hiring a Software Engineer, Buyer Growth

About the Role

Shape the future of buyer growth in livestream shopping. In this role, you'll lead engineering efforts that directly impact how new users join, explore, and stay engaged with the platform. You'll design and implement full-stack systems that power onboarding, referrals, notifications, and guest experiences—each tailored to convert and retain first-time buyers at scale.

What You’ll Do

  • Design and own end-to-end features, from backend infrastructure to frontend interactions, used by millions
  • Define architectural direction for systems that must be reliable, scalable, and adaptable during rapid growth
  • Collaborate with product, marketing, and data science to identify high-impact opportunities and test new approaches quickly
  • Instrument and analyze conversion funnels to uncover insights and drive measurable improvements in user retention
  • Guide fellow engineers and help elevate technical standards across teams

What We’re Looking For

  • At least 5 years of experience building user-facing systems in fast-moving, high-growth environments
  • Proven ability to own ambiguous problem spaces and deliver clear results
  • Solid expertise across both frontend and backend development
  • A user-first mindset—prioritizing real-world impact over technical elegance
  • Comfort navigating complex systems and integrating across layers
  • Ability to juggle multiple priorities in a dynamic setting

Nice to Have

  • Background in e-commerce, social platforms, or marketplace products
  • Experience with mobile or full-stack web frameworks
  • Familiarity with A/B testing, growth experimentation, and analytics pipelines

How We Support You

  • Flexible time off and company-wide breaks
  • Comprehensive health coverage (medical, dental, vision)
  • Remote work support, including home office and internet stipends
  • Monthly wellness, childcare, and app usage allowances
  • Family planning benefits, including fertility and adoption support
  • 401k with employer match up to 4% of base salary (US) or pension plans (international)
  • 16 weeks of paid parental leave with a phased return option
  • Expectation that all team members actively use the platform as both buyers and sellers

Work Environment

This is a hybrid role based in one of our major hubs—Seattle, New York City, San Francisco, or Los Angeles. You’ll need to live within commuting distance of your chosen location, with flexibility to work from home or the office. We value in-person collaboration for planning and team connection, balanced with the freedom to work remotely when needed.

Our Culture

We move quickly and learn as we go. We care more about results than recognition, stay close to our users, and believe curiosity and action drive progress. If you thrive in uncertainty, enjoy solving open-ended problems, and want to build for a growing community, you’ll fit right in.

We are an Equal Opportunity Employer. We do not discriminate based on race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, parental status, disability, or other protected statuses under local law.
