Senior Developer, Growth

1Password 1Password · Enterprise · United States, Canada · Remote · Technology

Senior Developer for the Growth Team at 1Password, focusing on building self-serve experiences, evolving systems, and driving experimentation for B2B product suites. The role involves shaping the experimentation platform, leading experiment design, partnering with product and data teams, and mentoring engineers. While the company leverages AI and encourages learning about it, this specific role is not directly building AI models or systems, but rather contributing to product growth in a company that uses AI tools.

What you'd actually do

  1. Shape and evolve our experimentation platform (feature flags, instrumentation, data quality, reporting loops).
  2. Lead the design and implementation of experiments that drive activation, engagement, and expansion.
  3. Partner closely with product, design, and data to refine hypotheses, define measurable outcomes, and interpret results.
  4. Balance rapid iteration with long-term architectural health and security.
  5. Raise the bar for code quality, observability, and performance across the team.
