Join an innovative financial technology organization building secure, scalable infrastructure that expands access to global investment markets. As a Principal Security Engineer, you will provide technical leadership in designing and implementing security capabilities across cloud infrastructure, trading platforms, applications, and corporate systems. You will combine hands-on engineering expertise with architectural vision to protect sensitive data, strengthen security operations, and support demanding regulatory requirements. Working across Engineering, IT, Risk, and Compliance, you will develop automated security controls and resilient platforms that enable business growth without compromising reliability. You will also mentor engineers, influence technical strategy, and lead complex initiatives from initial design through production deployment. This is an opportunity to make a measurable impact in a high-performance fintech environment where security, innovation, and operational excellence are essential.
Security architecture and technical leadership: Design and implement reusable security patterns, automated guardrails, and technical standards across product infrastructure and corporate environments. Lead complex engineering initiatives from architecture and testing through deployment, maintenance, and continuous improvement.
Cloud and infrastructure security: Strengthen security across AWS services, Kubernetes and EKS, EC2, DynamoDB, and colocated infrastructure by implementing least-privilege access, workload identity, network segmentation, encryption, and secure data access while preserving availability and trading performance.
Endpoint, identity, and SaaS security: Harden Windows and macOS environments, optimize endpoint protection, and automate identity and device controls using platforms such as Okta and JumpCloud. Improve privileged access management, phishing-resistant authentication, and secure configurations across corporate SaaS applications.
Application and container security: Integrate threat modeling, API security, automated security testing, container image signing, policy enforcement, and runtime protections into development pipelines, CI/CD, and GitOps workflows.
Vulnerability and exposure management: Automate source-code, dependency, container, and infrastructure scanning. Collaborate with Engineering and IT to prioritize remediation, validate fixes, and implement preventive measures that reduce recurring vulnerabilities.
Security operations engineering: Build, integrate, and maintain security platforms, including SIEM, SOAR, endpoint protection, and vulnerability management systems. Establish reliable provisioning, monitoring, documentation, and support procedures.
Detection and incident response: Engineer telemetry collection, normalization, and enrichment pipelines. Partner with Security and Threat Operations to develop detection logic, validate analytics, automate response playbooks, support threat hunting, and lead post-incident security improvements.
Compliance and regulatory automation: Translate requirements from Legal, Compliance, and Governance, Risk, and Compliance (GRC) teams into tested technical controls. Support regulatory obligations, including SEC Rules 17a-3 and 17a-4, automate evidence collection, and facilitate audits and regulatory examinations.
Data security and privacy: Develop and maintain capabilities for data discovery, classification, access control, encryption, retention, and secure deletion to support GDPR and other applicable privacy and data protection requirements.
Cross-functional collaboration and mentoring: Advise business leaders and engineering teams on security risks and technical trade-offs. Conduct architecture and code reviews, mentor engineers, document technical decisions and operational runbooks, and promote secure engineering practices throughout the organization.
