Blockchain Specialist

Location: London or Zurich (Hybrid 2x a Week)

I’m currently working with a well-backed technology company building real-world solutions across blockchain, security, and enterprise systems, who are looking for a Cryptography Research Engineer to take ownership of cutting-edge cryptographic systems from concept through to production.

This is a highly impactful role sitting at the intersection of research and engineering, focused on applying advanced cryptographic techniques to practical, scalable systems across both Web2 and Web3 environments.

You’ll be responsible for driving work across zero-knowledge proofs, post-quantum cryptography, and privacy-preserving technologies, contributing to systems that move beyond theory and into real-world deployment.

This is an opportunity to join a deeply technical team working on genuinely novel problems, where you’ll have the autonomy to shape both research direction and implementation.

Responsibilities

• Lead cryptographic research across areas such as zero-knowledge proofs, post-quantum cryptography, and privacy-preserving systems.
• Design, prototype, and implement cryptographic protocols for real-world applications.
• Translate complex research concepts into production-ready systems and infrastructure.
• Collaborate with engineering teams to integrate cryptographic solutions into scalable platforms.
• Contribute to system architecture across blockchain, security, and distributed environments.
• Stay at the forefront of emerging cryptographic research and apply it to practical use cases.
• Produce clear technical documentation and communicate complex concepts to both technical and non-technical stakeholders.

Requirements

• Strong background in cryptography, ideally with a research-led focus.
• Experience with zero-knowledge systems (e.g. zk-SNARKs, zk-STARKs) or related technologies.
• Understanding of post-quantum cryptography and modern cryptographic primitives.
• Strong programming ability in languages such as Rust, Go, Python, or C++.
• Experience working across distributed systems, blockchain, or security-focused environments.
• Ability to take ownership from research through to implementation and deployment.
• Strong communication skills and ability to work within highly technical teams.
