We’re looking for a Principal Cyber Security Engineer to join our Information Security team and play a pivotal role in safeguarding Jack Henry’s infrastructure, platforms, and customer data. In this senior, highly impactful position, you’ll leverage deep cybersecurity expertise to build, automate, and continuously elevate our security posture across both cloud and on-prem environments. You’ll bring hands-on experience across a broad range of security domains including observability, cloud security, application security, DevSecOps, incident response, and identity and access management and thrive in a fast-paced, collaborative environment where innovation is encouraged, partnerships are key, and security is embedded into everything we do.
This position may be worked remotely within the United States, with the exception of California. All positions, regardless of location, may require an onsite interview or in-person onboarding requirement to verify your identity.

What you’ll be responsible for:

- Develop and tune detection rules, alerting, and dashboards to improve visibility, response times, and security KPIs.
- Implement and enforce security controls across multi-cloud environments (AWS, Azure, GCP), leveraging CSPM, CWPP, and CNAPP solutions to protect cloud infrastructure and workloads.
- Develop infrastructure-as-code and policy-as-code guardrails to ensure secure, consistent cloud deployments.
- Embed security into CI/CD pipelines, integrating tools such as SAST, DAST, SCA, and container scanning to advance DevSecOps practices and reduce vulnerabilities early.
- Partner with engineering teams on secure coding, threat modeling, and vulnerability remediation efforts.
- Support incident response and threat management, including escalation, investigation, and continuous improvement of playbooks and response processes.
- Implement and enhance identity and access management (IAM), including zero-trust principles, least-privilege access, MFA, and privileged access controls.
- Identify and mitigate security risks, ensuring alignment with regulatory and compliance requirements (SOC 2, PCI-DSS, FFIEC, NIST), while mentoring engineers and driving adoption of scalable security practices.
- May perform other job duties as assigned.
What you’ll need to have:
- Minimum of 15 years of progressive experience in cyber security or site reliability engineering.
- Minimum of 5 years of hands-on experience with cloud platforms (AWS, Azure, or GCP) in a security-focused capacity.
- Minimum of 5 years of experience in cyber detection and incident response.
- Minimum of 3 years of experience with security observability and monitoring tools (SIEM, log management, APM).
- Demonstrated experience in DevSecOps practices.
What would be nice for you to have:
- Bachelor’s degree in Computer Science, Cyber Security, Information Technology, Computer Engineering, or a closely related technical field.
- Strong knowledge of networking fundamentals (TCP/IP, DNS, TLS/SSL, VPN, firewalls, load balancers)
- Experience with container technologies (Docker, Kubernetes) and their associated security challenges
- Working knowledge of regulatory frameworks relevant to financial services (PCI-DSS, SOC 2, FFIEC, NIST 800-53)
- Familiarity with offensive security concepts, penetration testing methodologies, and red/blue/purple team exercises
- Experience in the financial services or fintech industry with knowledge of banking regulations and compliance requirements
- Experience with security automation and orchestration (SOAR) platforms
- Hands-on experience with zero-trust network architectures and micro-segmentation technologies
- Background in threat hunting, digital forensics, or malware analysis
- Experience leading or mentoring security engineering teams
- Contributions to open-source security tools or active participation in industry security communities (DEF CON, BSides, OWASP chapters)
