- Create standards‑compliant world‑class software systems and components, most of which will be open sourced as our commitment to the 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:

- 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.
