About the position
At OPSWAT, we're building cutting-edge solutions that protect the world's critical infrastructure. You will play a pivotal role in shaping the future of our OESIS Framework platform with cloud solution integrations.
This role owns how the SDK authenticates into each customer's own tenant across Endpoint Device Management platforms without OPSWAT ever holding the customer's raw credentials. That passthrough model, plus secure multi-tenant token and credential storage, is the core of the job.
It is a software engineer role with an identity specialization: you will be writing and shipping the auth layer of an embedded SDK, not administering an IAM deployment.
What you will be doing
Design and implement OAuth2/OIDC flows per platform. For example the CrowdStrike API client-credentials flow, Microsoft Entra ID (Azure AD) app-registration and Graph API auth flows, and JAMF Pro OAuth2/bearer or client-credentials flows
Implement SAML 2.0-based federation for enterprise SSO passthrough scenarios where a customer's identity provider is the source of truth
Build secure, multi-tenant credential and token storage with rotation, integrating with secrets managers such as HashiCorp Vault, Azure Key Vault or AWS Secrets Manager
Design the passthrough auth architecture so the embedded SDK authenticates to the customer's own device management tenant directly, without OPSWAT storing or proxying raw customer credentials
Implement token refresh, expiry handling and re-authentication logic that integrates cleanly with the Data Engineer's long-running query pipelines
Define least-privilege scoping per platform and support certificate-based auth and mutual TLS where the vendor API allows it
Support customer onboarding: app-registration and consent flows for remote enrollment (Entra ID), API client setup (CrowdStrike), and API role and privilege configuration (JAMF Pro)
What we need from you
Strong experience in a systems or compiled language: Rust, Go or similar producing native, cross-platform artifacts for Windows, macOS and Linux
3+ years in identity and access engineering with hands-on OAuth2, OIDC and SAML 2.0, and ideally SCIM
Direct experience with Microsoft Entra ID (Azure AD) app registrations and Graph API authentication flows
Experience implementing OAuth2 client-credentials flows against third-party enterprise APIs such as CrowdStrike Falcon or JAMF Pro, or comparable
Strong grasp of token lifecycle management: refresh tokens, expiry, revocation, scope and claim design
Experience with secrets management and secure credential storage in multi-tenant SaaS environments
Familiarity with certificate-based authentication: mTLS and client certificates
Security-first mindset, with working knowledge of common auth vulnerabilities: token leakage, replay attacks, scope creep
Solid general software engineering ability, you own production code in this layer, not configuration alone
Professional working proficiency in written and spoken English
It would be nice if you had
Prior experience building passthrough or delegated auth architectures for OEM/SDK products embedded in third-party platforms
Background in enterprise IAM tooling (Okta, Ping Identity, Entra ID) or CIAM
Familiarity with Zero Trust Network Access (ZTNA) and device posture or compliance
Security certifications such as CISSP or OSCP
Cybersecurity domain knowledge alongside software development experience
Familiarity with regulatory compliance frameworks such as PCI-DSS, SOX or HIPAA
