Sr. Security Engineer

Snap Finance•West Valley City, UT

About The Position

We’re looking for a Senior Security Engineer to serve as a key technical leader on our Infrastructure Security Operations team. This role owns the day-to-day security of our multi-region AWS environment, including security tooling, incident response, vulnerability management, and automation. You’ll write code to eliminate manual work, leverage AI-native tools to improve efficiency, and help raise the technical bar across a growing team. In addition to operational ownership, you’ll support security metrics, compliance, and executive/board reporting. This role requires occasional after-hours support for critical security incidents and reports directly to the CISO.

Requirements

5+ years in security engineering, security operations, or a combined SecOps/program role
Must be authorized to work in the United States and be US-based
Hands-on experience operating cloud security tooling in AWS environments
Proficiency in at least one scripting or programming language — Python strongly preferred
Experience building dashboards, writing queries, and tuning alerts in a SIEM platform
Strong working knowledge of vulnerability management and incident response lifecycles
Experience supporting compliance frameworks: SOC 2, PCI DSS, or equivalent
Demonstrated use of AI and ML tooling in a professional security context
Track record of mentoring or upskilling peers in technical disciplines
Strong written communication skills — equally effective writing for engineers and executives
Comfortable with occasional after-hours availability for critical security incidents

Nice To Haves

Experience with GRC platforms: compliance automation, risk management, or audit evidence tooling
Exposure to IGA and PAM concepts and tooling
Security certifications: CISSP, CISM, AWS Security Specialty, or GIAC (GCIH, GCED, or similar)
Background in fintech, lending, or regulated financial services
Contributions to security tooling, open-source projects, or internal platform engineering
Experience with SOAR platforms or automated response workflows

Responsibilities

Secure and Operate the Cloud Environment: Own cloud security posture across multi-region AWS environments — continuously assess, harden, and improve. Operate the full security toolset: CSPM, SIEM, vulnerability management, network security, ZTNA, DLP, EDR, and endpoint management. Drive the vulnerability management lifecycle end to end: scan cadence, prioritization, remediation SLAs, and reporting. Manage identity and access infrastructure in collaboration with IT, spanning MFA, IAM, IGA, privileged access, and credential management. Lead the buildout of a Privileged Access Management (PAM) program. Support ongoing cloud migration security workstreams. Monitor threat intelligence and external attack surface signals; translate findings into prioritized action.
Lead and Respond to Incidents: Serve as a primary responder for security incidents — triage, contain, eradicate, and recover with urgency and discipline. Own incident response process maturity: playbook development, evidence chain of custody, forensic readiness, and post-incident reviews. Be available for occasional after-hours response when critical incidents arise.
Build, Automate, and Elevate the Team: Set the coding and AI standard for the InfraSecOps team — write tools, automate workflows, and actively mentor peers in modern security engineering practices. Build and maintain automation for alert triage, compliance evidence collection, asset inventory, and security metrics. Develop API integrations between security tools to eliminate manual handoffs and improve data fidelity. Contribute to security-as-code practices: IaC security reviews, CI/CD pipeline hardening, and software supply chain controls. Champion AI-native tooling across the team; evaluate and implement AI-assisted detection, threat hunting, and response capabilities. Build and contribute to Agentic AI frameworks within the security program. Stay current on AI security risks — prompt injection, model abuse, shadow AI — and turn awareness into practical controls.
Own the Security Program Within Your Domain: Maintain the security program roadmap and key results for your domain, including compliance attestation timelines and remediation SLA adherence. Track and mature the security tool portfolio: monitor adoption, measure effectiveness, and drive continuous improvement. Maintain risk registers and GRC platforms; ensure findings are triaged and resolved within SLA. Coordinate audit evidence collection for SOC 2 Type II, PCI DSS 4.0, and CyberEssentials+. Contribute to executive and board-level security reporting — translate operational data into clear program narratives. Drive cross-functional follow-through with Engineering, IT, Data, and PMO on security workstreams.
