Strong problem-solving and debugging skills in distributed systems.
Excellent communication skills and experience collaborating with cross-functional teams.
We Prefer If You Have
Experience building or maturing security infrastructure in a fast-paced or regulated environment.
Understanding of compliance requirements in fintech (e.g., SOC 2, PCI) and how to build guardrails that support them.
A track record of building internal tools or reusable platform abstractions adopted by multiple teams.
