Senior .Net/C# Developer, SaaS Manager

About the role

1Password is growing. We’ve surpassed $400M in ARR and we’re continuing to accelerate, earning a spot on the Forbes Cloud 100 for four years in a row and teaming up with iconic partners like Oracle Red Bull Racing. About 1Password At 1Password, we’re building the foundation for a safe, productive digital future. Our mission is to unleash employee productivity without compromising security by ensuring every identity is authentic, every application sign-in is secure, and every device is trusted. We innovated the market-leading enterprise password manager and pioneered Unified Access Management, a new cybersecurity category built for the way people and AI agents work today. As one of the most loved brands in cybersecurity, we take a human-centric approach in everything from product strategy to user experience. Over 180,000 businesses, from Fortune 100 leaders to the world’s most innovative AI companies, trust 1Password to help their teams securely adopt the SaaS and AI tools they need to do their best work. If you're excited about the opportunity to contribute to the digital safety of millions, to work alongside a team of curious, driven individuals, and to solve hard problems in a fast-paced, dynamic environment, then we want to hear from you. Come join us and help shape a safer, simpler digital future. 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. 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 hiring 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 involvement. Partner closely with product managers and designers to understand the customer problems behind the work, advocate for sound engineering, and help the team make good tradeoffs Bring a practical, hands-on perspective on where agentic AI tools create genuine leverage in your own workflow and share what works with your teammates Bonus points for: Experience evolving a legacy or growth-stage application into an enterprise-scale platform Comfort across a wide range of technical stacks (.NET/C#, MongoDB, Go, Rust, TypeScript, React, and others); you evaluate technology on its merits for the problem at hand, not personal preference, and you pick up new languages quickly USA-based roles only: The annual base salary for this role is between $153,000 USD and $214,000 USD, plus immediate participation in 1Password's benefits program (health, dental, 401k and many others), utilization of our generous paid time off, an equity grant and, where applicable, participation in our incentive programs.

At 1Password, we approach each individual's compensation with a promise of fair market value and internal equity commensurate with experience and specific skill set. This posting is for an existing vacancy. Our culture At 1Password, we prioritize collaboration, clear and transparent communication, receptiveness to feedback, and alignment with our core values: keep it simple, lead with honesty, and put people first. You’ll be part of a team that challenges the status quo, and is excited to experiment and iterate in search of the best solution. That said, 1Password is not for everyone . Our work is demanding, we strive for excellence, and the pace is fast. We need people who are keen to take on challenging problems, who seek feedback to grow, and who are driven to make an impact. If you're looking for a place where you can settle into a comfortable routine, this might not be the right fit for you. We’re looking for individuals who are proven experts in their fields, as well as those who are highly adaptable, can thrive in ambiguity and through change, are curious, and above all deliver results. We are committed to leveraging cutting-edge technology—including AI—to achieve our mission. We also understand that thinking critically about AI in its current forms will help us create better solutions for our customers and ourselves with its future forms, which will help us continue to close the gap between security and privacy and achieve our mission. We want team members at all levels to take th
