Director, Ecosystem Product Security (New York)
Interested in working on cutting‑edge blockchain technology and creating equitable access to the global financial system? Since 2014, the mission‑driven team at the Stellar Development Foundation (SDF) has helped fuel the tremendous growth of the Stellar blockchain network, an open‑source platform that operates at high‑scale today. Developers and companies around the world build on it, and the SDF team is expanding to support the rapidly growing and changing Stellar ecosystem. We're hiring a Director, Ecosystem & Product Security to lead security strategy across the Stellar ecosystem and directly own security outcomes for Foundation‑developed systems, Foundation‑operated infrastructure and treasury‑related security responsibilities.

Success means reducing real‑world security risk and financial loss through clear standards, effective coordination and practical improvements that are adopted in production. The role is both strategic and hands‑on. It requires deep technical judgment across decentralized systems, product security and operational risk, along with the ability to work across teams and influence independent ecosystem participants without direct authority. This is a highly cross‑functional and externally visible leadership role.
