Director, Ecosystem Product Security

Director, Ecosystem Product Security 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 Senior 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. This role is focused on raising the practical security baseline across a decentralized financial ecosystem that includes wallets, infrastructure providers, custodians, issuers, validators, and other critical participants. 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. The right candidate will combine technical credibility, sound judgment, and strong execution to help make security a durable strength of both the Foundation and the broader Stellar network. In this role, you will: - Define and lead the Foundation’s security strategy across both the Stellar ecosystem and Foundation-owned systems - Raise the practical security baseline for key ecosystem participants, including wallets, infrastructure providers, custodians, issuers, and validators - Publish actionable guidance, reference patterns, and security expectations that drive real adoption across the ecosystem - Build coordination mechanisms for shared risks, incident response, and cross-ecosystem security improvement - Own security outcomes for Foundation-developed software, Foundation-operated infrastructure, and treasury / custody-related responsibilities - Partner with Engineering, Finance, Legal, IT, and Corporate Security to drive implementation of security controls and secure operating practices - Lead secure development efforts across architecture, threat modeling, vulnerability management, bug bounty programs, and product incident response - Build and lead a high-performing security team, while translating strategy into execution plans and measurable outcomes - Represent the Foundation externally as a credible technical leader and convener on ecosystem security You have: - 10+ years of experience in security, including significant experience in senior leadership roles - 5+ years leading security programs, teams, or functions with meaningful scope - A track record of owning security outcomes for complex, high-consequence systems in production - Deep experience in product and application security, with hands-on judgment in real-world environments - Strong familiarity with blockchain and decentralized system security - The ability to assess and prioritize risk across areas such as protocol design, smart contracts, wallets, validators, dependencies, and governance mechanisms - Experience driving security improvements across multiple teams, organizations, or ecosystem participants, including in environments where you do not have direct authority - Strong incident judgment, including experience handling high-severity incidents and disclosure processes - A pragmatic approach to security, with the ability to make tradeoffs that reduce real-world risk rather than optimize for theoretical completeness - Experience buildi ...
