Location: Remote (United States | Canada) Workplace: Remote 1Password is growing. We’ve surpassed $500M 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. Our Infrastructure Services organization is responsible for the underlying infrastructure that powers the 1Password application. It includes Compute Services, Network and Edge Services, and Stateful Services. As a Senior Staff Cloud Platform Engineer, you set the multi-year technical strategy for Infrastructure Services. You decide where the organization invests, define the architecture and standards that every infrastructure team and internal tenant builds on, and make sure our compute, network and edge, and stateful platforms evolve as one coherent system rather than three separate ones. You partner with engineering and product leadership, security, and finance to balance reliability, security, cost, and delivery speed, and you are the senior technical voice for infrastructure across the company. This is a hands-on role. You write design docs, prototype, review the hardest designs, and step into the most serious incidents. But your main impact comes from making many teams more effective and from the decisions that hold up for years. 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: - You have set technical direction across multiple teams. You have owned an infrastructure strategy or architecture spanning several teams or an entire organization, and you can point to the multi-year outcomes: what others adopted, what shipped, and what measurably improved. - You have operated Kubernetes at production scale. This includes multi-cluster, multi-tenant, customer-traffic-bearing environments (EKS or similar managed platforms preferred). You know it deeply, from autoscaling and admission control to GitOps, workload identity, and fleet-wide cluster upgrades. - You combine depth with breadth. Beyond Kubernetes, you have working fluency in networking and edge and in stateful data systems, and you understand how a decision in one layer affects the rest. - You have made reliability a standard, not a project. You defined SLIs, SLOs, and error budgets, and you got multiple teams to adopt them. You have improved incident response, post-incident learning, and disaster recovery across an organization, not just on your own team. - You have cut cloud costs through engineering. You can show measurable, real-dollar impact from work such as capacity automation, right-sizing, architecture changes, or commitment strategy, and you have worked with finance on forecasting and tradeoffs. - You build security in by design. You have driven practices such as workload identity, least-privilege IAM and RBAC, credential rotation, and strong isolation in multi-tenant environments, and you have partnered with security teams on risk decisions and compliance requirements. - You still build. You are proficient in Go (or a similar language) and Infrastructure as Code (Terraform), and you have a track record of automating complex, high-toil operational workflows at fleet scale. - You influence without relying on authority. You write clear strategy and design documents, present to senior leaders, resolve technical disagreements between teams, and build alignment on difficult tradeoffs. - You grow other engineers. You have mentored Senior and Staff engineers, raised the bar on design review, and helped shape how your organization hires and evaluates technical talent. Bonus points for: - Hands-on experience with service mesh and service-to-service networking, such as Linkerd or Amazon VPC Lattice. - Experience operating scalable database technology, such as MySQL, Postgres, or DynamoDB. - Designing developer platform abstractions for internal teams, such as paved-road service toolkits and production readiness frameworks, that measurably improved usability and productivity. - Helping build AI-assisted operations tools, such as auto-remediation or AI-assisted diagnosis, rather than only using them. - Operating highly available, multi-region services in a large SaaS environment, including capacity planning and performance optimization at scale. - Experience in a security, identity, or other high-trust product environment. What you can expect: - Set the multi-year technical strategy and architecture for Infrastructure Services, working with directors and senior engineering leadership to shape roadmap and investment decisions, including build versus buy. - Define the patterns, standards, and guardrails across compute, network and edge, and stateful services that internal teams depend on for years. - Represent Infrastructure Services in cross-organization reviews with product engineering, security, and finance, and serve as the senior technical voice for the platform. - Serve as an escalation point for major incidents, and drive organization-wide improvements to incident management, reliability targets, and disaster recovery. - Lead cost, capacity, and efficiency strategy for our cloud footprint, with measurable goals. - Drive adoption of automation and AI-assisted operations to reduce toil across the organization. - Mentor Staff and Senior engineers, raise the bar on design review and engineering practice, and help us hire and develop the next generation of infrastructure leaders.
