• Experience with design systems, component libraries, or Storybook.

• Familiarity with programmable networks, observability tooling, or network automation concepts.

• Understanding of advanced security practices (CSP, threat modeling, RBAC patterns, dependency scanning).

• Experience in distributed systems or event-driven architectures.

• You treat the product as your own and prioritize long-term stability over short-term "hacks".

• Code-first and automation-first approach to solving problems.

• You are eager to work across the full stack and stay curious about the evolving tech landscape.
