About The Role

We are hiring a Head of Security to build and own Crossmint's security function as we enter a new phase of scale and regulatory maturity. This is a player-coach role: you will set strategy and own the program at the highest level, while remaining deeply capable of operating hands-on when the situation demands it. No delegation without comprehension.

This role carries wide scope. You will be responsible for Crossmint's overall security posture, from application and infrastructure security to corporate IT, from vendor and third-party risk to regulatory audit readiness. You will manage our Senior DevSecOps Engineer, work closely with Engineering, Compliance, Legal, and Ops, and our external security partners, serving as the internal authority on all things security for the leadership team.

Crossmint operates at the intersection of fintech and crypto infrastructure under a growing regulatory framework (SOC 2, DORA, MiCA), and an increasingly adversarial environment with AI. Security at Crossmint is not a cost center: it is a product differentiator and a requirement to operate. This role reflects that.

Responsibilities

Program Ownership and Strategy

• Define and own Crossmint's security strategy, including roadmap prioritization, risk posture, and security investment decisions.

• Operate fluidly across scope levels: board-level risk briefings one hour, hands-on threat model review the next.

• Establish and maintain a security program that scales with the company, not one that creates drag on product velocity.

• Report to co-founders on security posture, risk landscape, and program progress.

Technical Oversight and Hands-On Contribution

• Maintain deep technical fluency across cloud security (AWS primary), application security, CI/CD security, and endpoint and corporate IT.

• Review architecture decisions, new product features, and infrastructure changes for security implications before they ship.

• Conduct or lead threat modeling exercises across product and infrastructure domains.

• Step in as a hands-on practitioner during incidents, complex vulnerability analysis, or high-stakes security reviews where direct expertise is required.

Audit and Compliance Leadership

• Own security's relationship with auditors, regulators, and compliance frameworks including SOC 2 Type II, DORA, and MiCA-related security requirements.

• Lead audit preparation cycles: scope definition, evidence readiness, control documentation, and auditor-facing communication.

• Maintain audit-ready posture year-round, not as a sprint before each audit window.

• Partner with the Compliance function to ensure security controls satisfy both regulatory requirements and practical risk management objectives.

Third-Party and Vendor Risk

• Own the security review process for new vendors, integrations, and third-party relationships.

• Manage relationships with external security partners including our third-party audit firms and 24/7 incident response provider.

• Define and oversee our external penetration testing and security assessment program.

Team and Stakeholder Leadership

• Manage and develop the Senior DevSecOps Engineer, with the expectation of growing the security team over time.

• Serve as the internal authority on security for Engineering, Product, Compliance, Legal, and People Ops.

• Drive security awareness and culture across the company without creating friction that slows down product teams.

• Communicate risk clearly to non-technical leadership, translating technical realities into business decisions.

About You

Must Haves

• 8+ years in security, with at least 3 years in a security leadership or program ownership role.

• Deep technical fluency in cloud security, application security, and CI/CD security. This is not a policy-only role.

• Demonstrated experience owning a security compliance program end-to-end through at least one major audit cycle: SOC 2 Type II strongly preferred.

• Software engineering degree or software engineering experience that makes up for it.

• Deep familiarity with the latest AI / agentic tools.

• Prior experience in fintech, payments, or similarly regulated industries, where concepts like treasury management aren't foreign and security failures carry direct consequences for licensing, customer trust, and business continuity.

• Strong written and verbal communication skills, including the ability to brief executive and board-level stakeholders on risk without unnecessary jargon.

• Experience managing or mentoring security engineers.

• Ability to work flexible hours if an incident arises.

Nice to Haves

• Familiarity with DORA, MiCA, or EU financial services regulatory frameworks.

• Experience with crypto or blockchain security threat models.

• Track record of building a security function from an early or formative stage.

• CISSP, CISM, or equivalent certification.

How to Succeed

• Switch gears from a regulatory gap analysis in the morning to reviewing a GitHub Actions configuration in the afternoon without losing altitude on either.

• Build systems and programs that stand on their own — not policies on a Google Doc, but processes that actually get done across the org.

• Earn the trust of engineering teams by being useful, not obstructive.

• React to incidents quickly, mitigating impact fast, quickly root causing them, and ensuring the company learns for the next.

• Proactively prevent incidents by staying up to date on the latest threats, having a clear picture of the company's weaknesses, and being able to deploy defenses at scale.

• Manage up: keep leadership informed and earn their trust by competence when executing and clarity when communicating.

• Hire and develop security talent with the same rigor they apply to technical problems.

They should not be someone who:

• Requires a large team to be effective. This role starts lean.

• Manages from a distance without remaining technically sharp.

• Treats compliance as the ceiling of the security program rather than the floor.
