Senior Security Infrastructure Engineer

Glocomms is partnered with a premier investment management firm seeking a Senior Security Infrastructure Engineer to join its Core Engineering team. This role is ideal for a deeply technical engineer with a strong background in authentication systems, Python development, and enterprise security architecture. The successful candidate will be responsible for building and maintaining secure, scalable, and high-performance infrastructure critical to the firm's global operations.

Key Responsibilities:

  • Architect, implement, and maintain Kerberos-based authentication infrastructure across a hybrid environment (Linux, Windows, cloud).
  • Develop robust, production-grade Python tooling for automation, monitoring, and integration of security services.
  • Engineer secure-by-design solutions for identity, access management, and privileged access control across distributed systems.
  • Perform deep-dive analysis of authentication flows, protocol-level debugging, and performance tuning.
  • Collaborate with platform, network, and application teams to embed security into infrastructure and CI/CD pipelines.
  • Lead incident response and root cause analysis for complex security and authentication issues.
  • Contribute to the design of zero-trust architectures and next-generation identity federation strategies.

Required Qualifications:

  • 8+ years of experience in systems or security engineering roles, preferably in high-performance or regulated environments.
  • Expert-level knowledge of Kerberos, including cross-realm trust, ticket lifecycle, and integration with LDAP/Active Directory.
  • Advanced proficiency in Python, with experience building secure, scalable tools and services.
  • Strong understanding of authentication protocols (OAuth2, SAML, NTLM), encryption standards, and secure transport mechanisms.
  • Deep experience with Linux internals, system-level debugging, and performance profiling.
  • Familiarity with infrastructure-as-code (Terraform, Ansible) and container orchestration (Kubernetes).
  • Proven ability to work independently on complex problems and deliver high-quality, maintainable solutions.

Preferred Qualifications:

  • Experience in financial services or other highly regulated industries.
  • Contributions to open-source security or infrastructure projects.
  • Familiarity with modern identity platforms (Okta, Azure AD, HashiCorp Vault).
  • Certifications such as OSCP, CISSP, or RHCE are a plus.

Candidates must be local and/or open to relocating to the New York City Metropolitan area. This is a hybrid position that will require 3 days per week on-site in Manhattan.
