Software Engineer (Cryptography)

Join Robinhood's Cryptographic Services & Infrastructure team as a Software Engineer. In this high-impact role, you will help build and operationalize Robinhood's new in-house card-processing service, protecting sensitive financial and customer data. You will design, build, and maintain production services and infrastructure supporting key management, encryption, and decryption functions. You will also collaborate with internal engineering teams and participate in a rotating on-call schedule. Prior cryptography or security experience is preferred, but strong engineers with a passion for security are encouraged to apply.

• Design, build, and maintain production services and infrastructure supporting key management, encryption, and decryption functions.
• Help architect, launch, and scale Robinhood’s new in-house card-processing environment to protect sensitive card, financial, and tax-related data.
• Collaborate with internal engineering teams to support migrations, drive adoption of shared cryptographic capabilities, and ensure safe system design.

• While prior cryptography or security experience is highly preferred, we are excited to empower strong engineers with a passion for security to learn and grow their skills on the job
• Curiosity and willingness to learn security engineering principles and participate in a light on-call rotation
• Clear and concise communication skills, with a demonstrated ability to explain technical decisions and proactively collaborate when facing challenges
• Experience building, operating, or supporting production services, distributed systems, or infrastructure
• Proficiency writing production code in at least one modern programming language (such as Python, Go, Java, C#, or C++) with a strong ability to reason about complex systems
• Comfort working across multiple technical domains, including software development, infrastructure, and operational reliability
• Familiarity with key management, secrets management, or core cryptographic concepts (such as symmetric encryption or public/private key pairs)
• Prior experience in site reliability engineering (SRE), platform engineering, or cloud security
• Experience handling sensitive financial, payment, or card data in regulated environments
• Background in supporting internal customer migrations or driving platform adoption across engineering teams
