Role
Who you are
- We’re looking for someone who is broad, pragmatic, technically fluent, and comfortable in customer-facing settings
- The right person can balance strong security judgment with the pace and trade-offs of a fast-moving startup
- 10–15+ years of cybersecurity experience, including 3+ years in a senior leadership or director-level role
- Broad security background across multiple domains, not a single-specialty profile
- Strong application security experience and ability to assess technical risk without needing to be hands-on coding daily
- Experience operating in a startup, scale-up, or similarly resource-constrained environment where prioritization and pragmatism are critical
- Ability to evaluate risk, stack-rank priorities, and focus on the highest-impact security work
- Strong working knowledge of compliance frameworks such as SOC 2, PCI DSS, ISO 27001, GDPR, CCPA, DORA, and ideally FedRAMP
- Experience participating in or leading security incidents
- Strong cloud, SaaS security, IAM, endpoint security, and zero-trust fundamentals
- Familiarity with AI-assisted workflows and emerging AI/ML security risks
- Customer-facing communication skills, with the ability to support sales, security reviews, and executive-level customer conversations
- A collaborative, business-enabling approach to security — someone who helps teams find safe paths forward rather than defaulting to “no”
- Strong leadership presence and ability to build trust with security, engineering, executive, and go-to-market teams
- Experience in fintech, payments, security, bot mitigation, or regulated industries is a plus, but not required
- Must be based in the United States and authorized to work in the US without sponsorship
What the job involves
- Sardine is hiring a Deputy Chief Information Security Officer to partner closely with our CISO and help scale our security program as we grow
- This is a senior, high-impact role for a security leader who can operate across multiple areas, including application security, GRC, security operations, cloud and SaaS security, corporate IT, customer trust, and overall security strategy
- You’ll serve as a trusted partner to the CISO, help identify and prioritize the highest-risk areas, and represent Sardine’s security program with internal teams, customers, prospects, auditors, and industry stakeholders
- Partner with the CISO on Sardine’s overall security strategy, roadmap, priorities, and execution
- Help identify, prioritize, and address the highest-risk areas across the business
- Support security reporting, executive updates, budgeting, vendor evaluation, and planning
- Partner on key compliance initiatives, including PCI, SOC 2, ISO 27001, DORA, and future FedRAMP readiness
- Support incident response and act as a deputy incident lead when needed
- Work closely with Engineering on application security, secure SDLC, vulnerability management, threat modeling, and remediation
- Assess and improve security across cloud infrastructure, SaaS tools, IAM, endpoint management, and corporate IT systems
- Bring strong AppSec fluency, including understanding how code moves from design through production, CI/CD, testing, SAST/DAST, dependency scanning, and secrets management
- Partner with Product and Engineering on security considerations for AI/ML systems, bot mitigation, and abuse prevention
- Support customer-facing security conversations, RFPs, due diligence, security reviews, and executive briefings
- Help build trust with enterprise customers by translating technical security concepts into clear business language
- Partner cross-functionally with Legal, Sales, Engineering, Product, People, and IT
- Champion a pragmatic security culture that enables the business while managing risk
Our take
Identity and payment fraud is one of the biggest dangers facing online businesses. Sardine is setting out to solve this problem by building the first zero-day fraud prevention technology.
Sardine's technology traces intrinsic behaviour patterns to identify so-called "bad actors" online, and detects fraudsters using machine-learned fraud scores and user behavior biometrics.
The company calls itself the world's first FaaS (Fraud Detection as a Service), and its solutions are already drawing business from next-gen crypto and financial service institutions. Onboarding these institutions and scaling its customer base at pace will ensure that Sardine maintains its frontrunner position.
