Senior Staff Security Engineer, Security Development

As a Senior Staff Security Engineer in Security Development at Robinhood, you will be one of the highest-impact individual contributors in a builder-first security engineering org. You'll identify hard, high-leverage problems across authentication and identity infrastructure, cloud security, cryptography, and AI security, then design and ship solutions end-to-end. This role is based in Bellevue, WA or Menlo Park, CA, with in-person attendance expected at least 3 days per week.

What you'll do

• Identify and own the highest-leverage technical problems across Security Development, from authentication and identity infrastructure to cloud security, cryptography, and AI security, and drive them from concept through production while writing code
• Design and build security systems for Robinhood's AI and agentic infrastructure, including runtime authentication, credential management, and runtime validation systems that allow AI capabilities to operate safely and reliably at scale
• Build intelligent internal security platforms that use AI to multiply the program's effectiveness, including tooling that finds vulnerabilities faster, improves detection fidelity, and scales security coverage across the company
• Partner with engineering managers and senior technical leads across the four Security Development teams to establish priorities, resolve complex technical tradeoffs, and align roadmaps around shared cross-cutting investments
• Stay operationally close to production so your architectural decisions are always grounded in how systems actually behave at scale

What you bring

• 12+ years of software or security engineering experience, with a demonstrated track record at the Senior Staff or Principal level operating at IC7 scope
• A strong builder orientation: you have designed, built, operated, and maintained production security systems end-to-end rather than handing designs to other teams
• Deep expertise in one or more of Identity and Access Management (IAM), authentication systems, cryptography, cloud security (AWS), or infrastructure security, with genuine breadth across adjacent security domains
• Hands-on experience securing AI infrastructure, LLM integrations, agentic systems, or AI-adjacent authentication and credential management challenges
• Proficiency in Go and/or Python applied to building backend security platforms, internal tooling, or security infrastructure, not just scripting or automation
• Strong distributed systems fundamentals and comfort operating in a complex, multi-team production environment; you understand how large-scale systems fail and how to build security into them without slowing them down
• The ability to identify unstructured, high-impact technical problems independently and build a path to solving them without waiting for top-down direction

What we offer

• Base pay range of $247,000-$290,000 USD (compensation zone varies by location: Menlo Park, CA; New York, NY; Bellevue, WA; Washington, DC; Denver, CO; Westlake, TX; Chicago, IL; Lake Mary, FL; Clearwater, FL; or Gainesville, FL)
• Bonus opportunities and equity ownership
• 401(k) matching
• 100% paid health insurance for employees with 90% coverage for dependents
• Access to the Robinhood Employee Fund for eligible US employees to invest in a private employee fund with exposure to Robinhood Ventures funds
• Access to top-tier AI tools and continuous AI skill-building for all employees
• Lifestyle wallet, a highly flexible benefits spending account for wellness, learning, and more
• Employer-paid life and disability insurance, fertility benefits, and mental health benefits
• Paid time off including company holidays, sick time, parental leave, and more
• Exceptional office experience with catered meals, events, and comfortable workspaces
