The role

A security engineer at a cybersecurity-focused software company designs identity and access systems using OIDC/OAuth, SAML, and applied cryptography, securing authentication traffic and mission-critical systems. The role also applies Golang and reverse proxying to build secure services and resolve customer-facing access issues.

Full job description

Responsibilities:

Design, build, and harden identity and access flows OIDC/OAuth 2.0 SAML 2.0 LDAP/Active Directory integrations that sit in front of mission-critical systems.

Own token and assertion lifecycle correctness: issuance, validation, expiry, rotation, and failure-mode handling for JWT/JWKS and SAML assertions.

Apply strong applied-cryptography and PKI practices (X. 509 certs, key rotation, TLS) to keep the auth path secure by default, not as an afterthought.

Build and maintain reverse-proxy/HTTP-layer components (TLS termination, header handling) that front customer authentication traffic.

Debug and resolve customer-facing identity/access issues, working with support and sales to triage escalations quickly.

Contribute to build/release and cross-platform packaging (Linux deb/rpm, Windows MSI) as needed.

Maintain a small Windows companion application written in C#/. NET.

Write and enhance end-to-end tests covering auth flows, failure modes, and edge cases (clock skew, revoked tokens, malformed assertions, etc. ).

Document known issues, workarounds, and design decisions in the team knowledge base as the team and product mature.

Communicate clearly with product and engineering stakeholders on design tradeoffs, security posture, and escalation status.

Requirements:

Strong hands-on programming skills in Golang.

Deep, practical knowledge of identity protocols: OIDC/OAuth 2.0 and SAML 2.0 including token/assertion internals, standard flows, and failure modes.

Working knowledge of LDAP/Active Directory.

Applied cryptography/PKI experience: X. 509 JWT/JWKS, key rotation, TLS.

Strong security engineering discipline, comfortable reasoning about threat models and building software to protect mission-critical systems, not just make features work.

Solid understanding of OS fundamentals, networking, and concurrency.

Working knowledge of Linux; comfortable writing shell/bash scripts.

Simple, effective written and verbal communication.

Nice-to-have:

Directory internals (LDAP schema, bind operations).

HTTP internals and reverse proxying (TLS, header injection).

Build/release and cross-platform packaging (Linux deb/rpm, Windows MSI).

Secret-manager internals, Redis, Win32 policy engines.

Basic C#/. NET (to maintain the companion app).
