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 building, leading, and developing high-performing security teams
The ability to set strategy, translate it into execution, and deliver measurable outcomes
Clear communication skills and the credibility to work effectively with engineers, executives, and external ecosystem participants
Experience operating in environments where security failures could lead to financial loss, operational disruption, or loss of trust
Bonus Points if (optional):
Experience with secure development frameworks such as NIST SSDF
Familiarity with Web3 security frameworks such as OWASP SCSVS or SEAL
Experience in financial infrastructure, payments, custody, or tokenized finance
Experience with large-scale platform or ecosystem security architecture
Experience in identity, trust, encryption, or internet-scale systems
