Role: Senior Blockchain Security Engineer

Location: London HQ. No in-office requirements

Salary: up to £160,000 fixed + attractive bonus and benefits package


You'll be joining a growing security engineering function, with a focus on securing blockchain-connected infrastructure, cryptographic systems, cloud platforms and applications within a fast-growing, highly regulated FinTech


This is a hands-on engineering role for someone who enjoys building security solutions rather than simply reviewing them. You can expect to work closely with Engineering and Platform teams writing production-level Golang, automating security controls and developing secure infrastructure for incredibly highly-sensitive financial systems.


For this role, it's imperative that you have experience securing crypto/blockchain/digital asset environments


You'll be:

  • Building security capabilities across blockchain, payment and cloud infrastructure.
  • Securing cryptographic key management and HSM-backed services.
  • Designing and implementing secure application and API architectures.
  • Embedding security controls throughout CI/CD and the Secure SDLC.
  • Developing security tooling and automation using Go.
  • Implementing and improving SAST, DAST, SCA and threat modelling capabilities.
  • Supporting secure blockchain and digital asset transaction infrastructure.


You'll need:

  • 8+ years’ experience across security engineering, application security or blockchain security.
  • Experience securing blockchain, crypto, digital asset or payment environments.
  • Very strong AWS security engineering experience.
  • Knowledge of application security, threat modelling and DevSecOps.
  • Experience with SAST, DAST, SCA or equivalent AppSec tooling.
  • Understanding of secure APIs, authentication, authorisation and data protection.
  • Experience working with regulated financial or payments environments is highly desirable.
  • A strong engineering mindset with a track record of building and shipping security capabilities.
