Job description

Head of Security Engineering (DevSecOps & CISO)

ABOUT SMARKETS

Smarkets is a prediction market exchange for sports and political trading, having handled over $50 billion in volume since 2010. We're upending sports betting with the fairest prices, the best technology, and a superior customer experience — powered by attracting great people and building a high-performance environment where they thrive. We're looking for an atypical candidate with strong regulated-business experience to support our growing CFTC business.

THE ROLE

This is our inaugural security hire, working alongside Infrastructure to protect the distributed, real-time systems behind our trading engine. You'll lead our information security programme across our core products and our DCM/DCO entities — a founding build, standing up security engineering from the ground up through go-live and maturing it as we scale. Reporting directly to senior leadership and the Board, you'll own security posture updates and ensure our risk management and incident response frameworks exceed regulatory and operational standards.

ABOUT YOU

• Security expert with hands‑on experience building security engineering/DevSecOps capabilities in a cloud‑native, high‑growth environment — ideally financial services or exchange infrastructure

• Excellent communication skills for executive, board, and regulatory audiences

• Familiarity with CFTC system safeguards expectations, including 17 C.F.R. § 38.1051 and § 39.18 or similar regulatory requirements

• Strong grasp of application security principles (OWASP Top 10, NIST) and secure SDLC practices

• Proficiency with CI/CD tooling (GitHub Actions, GitLab CI, Jenkins, Azure DevOps, CircleCI) and security tools (Snyk, Aqua, Trivy, Checkov, Twistlock, Clair)

• Hands‑on expertise securing AWS/Azure/GCP, Kubernetes, containers, and IaC

• Proficiency in Python, Bash, Go, or similar

RESPONSIBILITIES

• First dedicated security engineering hire, working from within Infrastructure and Engineering teams to establish and evolve Smarkets' security capabilities

• Own regulatory/industry engagement (including CFTC), reflecting external expectations in internal practice

• Define a pragmatic, risk‑based security strategy across cloud infrastructure, applications, trading systems, and corporate environment

• Lead or support the investigation, containment and remediation of security incidents, including post‑incident root cause analysis and corrective actions.

• Work with Engineering teams to build security into the SDLC — SAST, DAST, SCA, container/IaC scanning in CI/CD — without becoming a delivery bottleneck

• Implement controls across AWS, Kubernetes, containers, and IaC, hardening identity, secrets, and network access

• Establish security monitoring and detection across applications, APIs, and infrastructure

• Develop and maintain security policies, standards, and controls meeting DCM/DCO requirements

• Maintain evidence and documentation to support regulatory examinations and audits

• Act as a security partner to engineers, building a culture of ownership over security

DESIRABLE

• Personal interest in sports, exchanges, or trading

• Certifications: DSOP, CKS, CISSP, CCSP, CSSLP, or AWS/Azure/GCP Security Specialty

• Track record of security automation at scale in Agile/Scrum

• Direct experience with regulators/examiners on technology and system safeguards

• Familiarity with event contracts, prediction markets, or similar novel futures products under CFTC
