Senior Software Engineer - Identity
DFINITY
Software Engineering
Zürich, Switzerland
Posted on Jan 13, 2026
You have deep experience across frontend and backend engineering and hold yourself to high standards of quality and craft. You enjoy working end to end, from visual and interaction designs through modern frontend technologies and backend interface design and implementation. If this sounds like you, let’s talk!
DFINITY is seeking a Senior Software Engineer to join its Zurich headquarters and help build the next generation of decentralized identity. As a member of the Identity team, you will be working on Internet Identity (id.ai), a privacy-preserving authentication system powering a growing ecosystem of applications on the Internet Computer and beyond. Instead of traditional usernames and passwords, it abstracts away concrete methods, integrating passkeys and other authentication systems like Google, Microsoft or Apple.
Your Responsibilities:
- Design and implement high-quality, intuitive user interfaces with a strong focus on usability and clarity.
- Work with stakeholders to gather requirements, evaluate tradeoffs, and shape technical solutions.
- Rapidly prototype and iterate on proof-of-concept implementations.
- Collaborating closely with cross-disciplinary teams including engineers, designers, researchers, and product managers.
You Bring:
- Significant experience as a senior full-stack or front-end–leaning engineer.
- Deep knowledge of frontend technologies such as HTML, CSS, and TypeScript.
- Strong experience with modern frameworks such as React; experience with Svelte is a plus.
- Working knowledge of at least one systems programming language, such as Rust.
- Experience designing, deploying, and operating production systems that run 24×7.
- A degree in Computer Science or equivalent practical experience. While the unique challenges at DFINITY have attracted many engineers with advanced degrees, your practical experience is more important to us than your educational background.
Who We're Looking For:
- Engineers motivated by building the next generation of products and platforms, and comfortable navigating tradeoffs between UX, privacy, and security.
- Collaborative team players who enjoy working with highly capable peers and believe the best solutions emerge through thoughtful, team-driven problem solving.
* Please note that this role requires in-office work from our amazing office in Zurich 3+ days per week
