Come join us and help shape a safer, simpler digital future. As part of the SaaS Manager team, you'll be building the platform that IT and Security teams rely on to discover, govern, and optimize their AI and SaaS ecosystems (work that just earned 1Password recognition as a Leader in the 2026 Gartner® Magic Quadrant™ for SaaS Management Platforms). You'll work on real problems: uncontrolled AI spend, shadow IT, SaaS sprawl, and the complex access lifecycles that come with it. Following 1Password's acquisition of Trelica in early 2025 , you'll join a collaborative team with a startup mindset backed by the resources and mission of one of the most trusted names in security. As we scale the platform to meet our enterprise-scale ambitions, you'll help shape not just what we build, but how we build it. We are looking for a Senior Developer who can go deep on complex problems and come up for air to bring their team with them; someone who ships high-quality work with a high degree of independence, champions technical excellence within their team, and makes the engineers around them better in the process. This is a remote opportunity within Canada and the US, ideally with the ability to work within Eastern Time hours. What we’re looking for: You have 5+ years of experience in software development, with strong working knowledge of .NET/C#/MongoDB or similar. You can tackle large, complex engineering problems with a high degree of independence. You're a subject matter expert in the features and systems your team owns; you identify gaps, propose improvements, and leave code meaningfully better than you found it. You champion technical innovation within your team: you evaluate new tools and approaches critically, advocate for the ones worth adopting, and help your teammates understand why. You set a high bar for code quality through thorough code reviews, strong test coverage, and clear documentation. You share your reasoning in a way that helps others grow. You communicate well across technical and non-technical contexts: you can write a clear design doc, facilitate a productive engineering discussion, and explain a hard problem to a partner without losing the plot. You have a practical, curious approach to agentic AI in the software development lifecycle: you use it where it creates real leverage in your own work, form opinions about what's actually useful, and share what you learn with your team without needing to be prompted You're a strong mentor: you guide less experienced developers through pair programming, code review feedback, and technical conversations, and you do it in a way that builds their confidence and independence over time What you can expect: Own the design and delivery of complex features end-to-end, from initial scoping through production, with minimal guidance and a high standard for what "done" means Contribute to and lead technical design discussions within your team: write clear design documents, surface risks early, propose solutions, and build consensus around the right approach Set and uphold best practices within the team (e.g. testing strategies, code quality norms, observability standards, etc.) and make sure they stick through code reviews and hands-on involv
