Come join us and help shape a safer, simpler digital future. We are seeking a Senior Developer to join our Growth Team, focused on building net-new self-serve experiences, evolving the underlying systems and integrations that power Product Growth, and driving rapid experimentation and feedback loops across our expanding B2B product suites. How we’re using AI today Our Engineering, Product, and Design teams are thoughtfully integrating AI across the full software and product development lifecycle to move faster without sacrificing quality or security. In practice, that looks like engineers using AI-assisted coding tools to accelerate reviews and catch bugs earlier, product managers synthesizing user research at scale, and designers rapidly prototyping and iterating with AI-generated mockups. We approach AI the same way we approach security: with clear principles, human accountability at every consequential decision point, and rigorous evaluation before anything ships to customers. This is a remote opportunity within Canada and the US. What we're looking for: - 5+ years of professional software development experience in a production SaaS environment. - Strong experience building backend services in a modern language (e.g. Go, Node.js, Ruby, or Python). - Deep experience with React and/or TypeScript in customer-facing web applications. - Strong understanding of instrumentation, analytics, and defining meaningful success metrics. - Ability to operate autonomously, drive initiatives forward, and influence technical direction. - Strong collaboration skills and a growth mindset. Bonus points for: - Demonstrated experience leading or significantly contributing to experimentation-driven product development. - Familiarity with analytics platforms (e.g., Amplitude, Looker, Qualtrics). - Experience working in security- or compliance-sensitive domains. What you can expect: - Shape and evolve our experimentation platform (feature flags, instrumentation, data quality, reporting loops). - Lead the design and implementation of experiments that drive activation, engagement, and expansion. - Partner closely with product, design, and data to refine hypotheses, define measurable outcomes, and interpret results. - Balance rapid iteration with long-term architectural health and security. - Raise the bar for code quality, observability, and performance across the team. - Mentor engineers through code reviews, technical design discussions, and pairing. - Identify technical opportunities to unlock new growth mechanisms. - See your work directly influence measurable customer and business outcomes. USA-based roles only: The annual base salary for this role is between $153,000 USD and $214,000 USD, plus immediate part
