About the Role

As a Senior Rust Developer, you'll join a highly skilled, cross-functional team building ExpressKeys — a dedicated, privacy-first password manager trusted by millions of users worldwide.

You'll be working at the intersection of security and user experience, helping people take control of their passwords through zero-knowledge encryption, cross-device syncing, 2FA code generation, and proactive breach monitoring

In this role, you’ll work at the technological forefront of modern network security.

You’ll design and build robust, scalable, and performance-critical systems in Rust, helping shape the next generation of our security infrastructure. From high-performance networking services to secure backend systems and privacy-by-design components – your work will not only challenge you technically, but make a tangible impact on the protection of users worldwide.

For us, Rust is not an experiment, but a strategic cornerstone technology for building robust, secure, and high-performance systems. In this role, you’ll not only help shape our technical transition to Rust, but also actively contribute to architecture decisions and long-term technology direction.

What You’ll Do

• Design, develop, and maintain software solutions in Rust (edition 2024)

• Implement system components with a focus on performance, memory safety, and concurrency

• Integrate Rust components into existing software ecosystems (e.g. REST, uniffi bindings, multi-platform support)

• Collaborate closely with DevOps, QA, and Architecture teams

• Conduct code reviews and ensure high code quality through automated testing

• Participate in architectural decisions and select appropriate libraries/frameworks (e.g., Tokio, Actix)

• Document your components, traits, and implementation details clearly

What you’ll bring

Must-have:

• Solid experience with Rust, including asynchronous programming (Tokio or async-std)

• Proficient in Git and comfortable working with build tools and CI/CD pipelines

• Familiarity with system architecture, memory management, and low-level programming

• Proficiency in object-oriented principles within Rust (traits, generics, dyn vs impl)

• Strong understanding of lifetimes and the borrow checker

• Solid English communication skills, both written and spoken (team language)

Nice-to-have:

• Knowledge of WebAssembly or embedded development

• Familiarity with security topics (e.g., memory safety, sandboxing, secure coding practices)

How we’ll support you:
