- Experience with NodeJS, React, and TypeScript.
- Proven experience building and scaling large-scale, distributed systems where data consistency, high availability, and performance under heavy load are hard requirements.

- Experience integrating modern AI development tools into your workflow to boost velocity, combined with the rigorous engineering discipline required to guarantee code safety and quality.

- Demonstrated experience working collaboratively in cross-functional teams.
- Expertise in the full software development life cycle.
- Previous experience building digital asset custody solutions or working at a digital asset-focused financial service business- Advantage.
