In this role, you will work with global peers on teams dedicated to areas of the product portfolio, from product, design, infrastructure, architecture, and back/front‑end engineering teams. You will be responsible for the continued enhancement and development of a multi‑component platform, where your expert skills in designing, architecting, and building quality systems will intersect with your hands‑on coding, performance testing, and integration experience.

  • We embrace experimentation and build fast
  • We have the courage to be misunderstood
  • We work together to unlock data

Affinidi’s focus on the open source community, and collaboration with standards bodies to develop the next version of the internet – the Internet of Trust – guides every engineering and product decision we make.

What’s in it for you:

  • Build and deliver secure, high‑quality features and improvements for the Affinidi Elements Platform using Rust. Experience in TypeScript and Dart will set you above other applicants for this role
  • Create standards‑compliant world‑class software systems and components, most of which will be open sourced as part of our commitment to OSS and decentralised community
  • Influence architectural direction and long‑term technical strategy while staying hands‑on with development
  • Design and implement solutions to complex, large‑scale technical challenges
  • Identify and drive the most critical improvements in product quality, security, and performance
  • Raise the bar for engineering excellence through mentorship, code reviews, and workshops
  • Guide the team to build well‑tested, secure, and performant services
  • Establish and refine best practices for high‑scale distributed systems
  • Collaborate closely with product, security, and engineering peers in a fast‑paced, iterative environment

You will be a great match if you:

  • Have deep knowledge of TypeScript/Node.js and Dart (experience in C# or Go is a plus)
  • Have expertise in cloud computing (AWS) and cloud‑native environments
  • Have a proven track record in designing and deploying distributed systems using modern design patterns
  • Are skilled in technical documentation (C4 Model, ADRs) and clear communication of architectural decisions
  • Are a strong advocate for privacy by design, security‑first principles, and high‑performance systems
  • Have expertise applying asynchronous cryptography in production‑grade products
  • Have experience with authorization/authentication domains; knowledge of identity, verifiable credentials, or secure data exchange is a strong plus
  • Can thrive in autonomous, fast‑moving startup environments and collaborate across global teams
  • Have experience working across functions, locations, and time zones
  • Have expertise in decentralized identity solutions
  • Have experience building systems with advanced cryptography requirements

What can you expect from us:

  • Unlimited vacation policy
