About the role
We are looking for a solution-oriented Staff Software Engineer (Backend) with deep, demonstrable expertise 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, including product, design, infrastructure, architecture, and front/back‑end engineering. 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 hands‑on coding, performance testing, and integration experience.
Key responsibilities
- 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.
Ideal qualifications
- Proven experience with performance optimization and a track record of diagnosing and preventing system bottlenecks.
- Strong backend development skills with Rust as a core expertise.
- Deep knowledge of TypeScript/Node.js; Dart experience strongly preferred. Familiarity with C# or Go is a plus.
- Expertise in cloud computing (AWS) and cloud‑native environments.
- Proven track record in designing and deploying distributed systems using modern design patterns.
- Skilled in technical documentation (C4 Model, ADRs) and clear communication of architectural decisions.
- Strong advocate for privacy by design, security‑first principles, and high‑performance systems.
- Expertise in applying asynchronous cryptography in production‑grade products.
- Experience with authorization/authentication domains; knowledge of identity, verifiable credentials, or secure data exchange is a strong plus.
- Comfortable thriving in autonomous, fast‑moving startup environments and collaborating across global teams.
- Experience working across functions, locations, and time zones.
- Expertise in decentralized identity solutions and building systems with advanced cryptography requirements.
