Come join us and help shape a safer, simpler digital future. We are excited to welcome a Senior Security Engineer to join our Product Security team at 1Password. Product Security helps enable 1Password to build and deliver secure products with confidence. We own the end-to-end security lifecycle across our products, platforms, and infrastructure, including our vulnerability management program, bug bounty program, coordinated disclosure, pentesting, and supply chain security. As part of this team, the Senior Security Engineer will lead and mature our incident response capabilities, working in close partnership with Engineering, Legal, Communications, and Customer Success to coordinate the company's response when product security incidents occur. This is a high-impact role for someone who thrives under pressure, cares deeply about protecting users, and wants to do meaningful work at a company trusted by millions. 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 career experience in IT or Engineering with a security focus Hands-on experience leading or participating in security incident response, ideally in a product or SaaS company context Experience with coordinated vulnerability disclosure (CVD) and managing relationships with external security researchers Strong judgment under pressure: you make clear, defensible decisions during time-sensitive situations with incomplete information Experience building or formalizing incident response capabilities from the ground up (playbooks, runbooks, severity frameworks, escalation processes) Experience drafting or contributing to customer security advisories, CVEs, or public-facing incident communications Strong communication skills across a wide range of audiences, from engineers to executives to customers Comfort reading and writing code to support forensic analysis, automation, and tooling Adaptable and resilient: you thrive in fast-paced environments where priorities can shift quickly Experience leveraging AI/ML capabilities to accelerate security workflows, automate repetitive tasks, or improve detection and response Bonus points for: Familiarity with CVSS, EPSS, and vulnerability severity frameworks as they apply to incident prioritization Experience in a consumer or B2B SaaS environment where customer trust and public perception are high stakes Familiarity with Software Bill of Materials (SBOMs) and supply chain risk as it relates to security incidents Experience with compliance standards and certifications (e.g., SOC 2, ISO 27001) and their intersection with incident reporting obligations Relevant certifications such as GCIH, GCFE, GCFA, PNPT, or similar (valued but not required) What you can expect: As part of this program, the Senior Security Engineer will: Lead end-to-end response to product security incidents, from discovery, triage, remediation, and disclosure. Own and evolve 1Password's PSIRT function, including incident classification frameworks, severity models, escalation paths, and response playbooks Drive coordinated vulnerability disclosure (CVD) processes, partnering with our bug bounty program and external security researchers to manage responsible disclosure timelines and communications Serve as the primary coordinator across Product Security, Engineering, Legal, Communications, and Customer Success during active security incidents Lead post-incident reviews (PIRs) and translate findings into systemic improvements across our products, processes, and detection capabilities Develop and maintain incident response tooling, automation, and reporting that reduce time-to-detect and time-to-respond Contribute to customer-facing security advisories, CVE disclosures, and public incident communications in partnership with Legal and Communications Evaluate and integrate AI-powered tooling and workflows that improve the speed and effectiveness of incident detection and response Mentor other engineers and help shape the long-term maturity of our product security and incident response capabilities. Serve on an on-call rotation with out-of-business-hours coverage. At 1Password, we build with AI: At 1Password, using AI to do more with less isn't a bonus — it's how we operate, and it's especially central to this role. We expect you to come in and actively build Incident Response tooling with AI, not just use off-the-shelf tools. A proven builder: You've built something — an agentic evidence collection workflow, an AI-assisted vendor questionnaire reviewer, an LLM-powered control narrative pipeline — and you can walk through what you built, the choices you made, what you iterated on, and what the measurable impact was. Systems thinking: When you describe an automation you built, you can explain how it changed downstream workflows, not just what it saved on the immediate task. 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. Canada-based roles only: The annual base salary for this role is between $144,000 CAD and $202,000 CAD, plus immediate participation in 1Password’s generous benefits program (health, dental, RRSP 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
