Jobbeschreibung

About the role:

We are in search of a solution-oriented Staff Software Engineer (Backend) with deep, demonstrable expertise and experience in Rust to lead the development of secure, scalable, and high-performance backend systems for the Affinidi Elements platform. 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.

Culture & values

• We are unapologetically customer‑focused
• We invest in cultures and teams to enable high performance
• We embrace experimentation and build fast
• We have the courage to be misunderstood
• We work together to unlock data

Further, 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 the 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 proven experience with performance optimization and a track record of diagnosing and preventing system bottlenecks
• Possess strong backend development skills with Rust as core expertise
• Have deep knowledge of TypeScript/Node.js and Dart; experience with 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
• Be skilled in technical documentation (C4 Model, ADRs) and clear communication of architectural decisions
• Advocate for privacy by design, security‑first principles, and high‑performance systems
• Have expertise in applying asynchronous cryptography in production‑grade products
• Have experience in authorization/authentication domains; knowledge of identity, verifiable credentials, or secure data exchange is a strong plus
• Be comfortable thriving in autonomous, fast‑moving startup environments and collaborating across global teams
• Have experience working across functions, locations, and time zones
• Be familiar with decentralised identity solutions
• Have experience building systems with advanced cryptography requirements

What can you expect from us:

• Unlimited vacation policy
• Competitive compensation package
• Work within an international environment
• Learning budget
