Sr. Software Engineer - Platform Permissions

Your impact

• Design, build, and operate the authorization platform - the roles, policies, and access checks that other teams build on top of
• Improve the speed and reliability of permission checks so they stay fast as usage grows, and set the performance and availability goals that keep them there
• Build the interfaces, libraries, and tooling that other engineering teams use to easily add access control to their own features, so they can move quickly and safely
• Lead the migration of older, hard-to-maintain permissions logic onto the modern authorization platform, reducing risk and complexity along the way
• Raise the technical bar through thoughtful design reviews, pragmatic code review, and clear written proposals that help the team make good decisions together
• Mentor engineers, share context generously, and partner with product, security, and engineering teams to turn ambiguous access-control needs into simple, well-understood systems
• Own quality end-to-end - automated testing, controlled rollouts (with feature flags), and observability - so authorization changes ship safely without disrupting the teams that depend on them

Qualifications

• Work comfortably across the stack - backend services and customer-facing interfaces - and pick up new languages and tools as needed
• Diagnose and improve performance and reliability in systems that serve high request volumes
• Drive to root causes and cut unnecessary complexity rather than patch symptoms
• Experience with authorization, authentication, or other security-sensitive systems is a plus
• Communicate proactively and clearly in writing and conversation, explaining technical trade-offs to both engineers and non-engineers
• Collaborate generously across your team and with engineering teams org-wide - giving and receiving feedback well and helping others do their best work
• Prioritize team delivery over individual productivity

Must have

• 7+ years of professional software engineering experience building and operating production systems
• Fluency with AI coding agents - experience with any of the available agents, understanding of common concepts, and willingness to learn and utilize AI for building
• Depth in some of the languages we use - Ruby on Rails, Go, or React with TypeScript - or the ability and desire to become effective in them quickly
• A track record of designing and owning non-trivial Platform systems end-to-end
