Senior Developer, Product Security

Security and data privacy are at the core of everything we do at 1Password. The Product Security Team is responsible for implementing new security features across our macOS, iOS, Android, Windows, Linux and Web applications as well as building libraries to share common security-critical code, resolving security vulnerabilities across our applications, and promoting secure coding practices across the organization.

As a Senior Developer on our Device Security squad, you will play a key role in implementing the next generation of security features in our applications, and help shape our security operations and best practices. You'll be intimately involved in ensuring secure coding practices across our code-base, guiding product teams on best practices, resolving security vulnerabilities in our products when they arise, and demonstrating leadership in the area of secure coding and development.

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 the US.

What we're looking for:

• 5+ years of experience in software development with a security angle; development experience with modern encryption techniques and libraries or authentication protocols

• 3+ years of hands-on experience with Rust development and creating FFI interfaces. Technical expertise in or willingness to learn languages such as Go, Typescript etc.
• Familiarity with Secure Enclave and HSM functionality with proven experience in areas such as biometric security including Face and Touch ID, Secure boot chain, code signing, memory protection etc.
• A strong understanding of and passion for the security domain; that could include understanding of topics in the sub-domains of cryptography, network security, application security, common threat vectors, and access control mechanisms etc.
• Excellent written and verbal communication skills; our security team often communicates nuanced topics to a variety of internal audiences, and has to understand these nuances during the design phase
• Knowledge of and practical experience with Agentic AI Model capabilities and workflows
