[Hiring] Senior Go Developer @Intetics

Role Description

Intetics Inc., a global technology company providing custom software application development, distributed professional teams, software product quality assessment, and “all-things-digital” solutions, is seeking a highly skilled and experienced Go Developer to join our dynamic team on a full-time basis.

We are looking for a Senior/Lead Go Backend Engineer with strong Identity and Access Management (IAM) expertise to design, build, and operate secure, high-performance authentication services.

The candidate should have:

• 7+ years of backend engineering experience
• 5+ years with Go
• 3–4+ years working with authentication, authorization, SSO, MFA, OAuth 2.0, OpenID Connect, JWT, and session management in production environments

Project Responsibilities:

• Design, develop, and operate high-throughput, low-latency identity services: Single Sign-On (SSO), Multi-Factor Authentication (MFA), session management, and federation.
• Own features end-to-end from design through production and support.
• Implement and scale modern authentication and authorization protocols and token formats (OAuth 2.0, OpenID Connect, JWTs), including secure token issuance, rotation, and revocation strategies.
• Write clean, concurrent, and highly performant backend services primarily in Go; design idiomatic, testable code and clear API contracts (gRPC/HTTP).
• Use your DevOps experience to deploy, manage, and automate identity infrastructure (CI/CD, monitoring, and incident response).
• Serve as the subject matter expert on authentication and identity: own internal security reviews, threat modeling for identity flows, and guide other teams on secure integrations with our platform.
• Integrate and maintain solutions with custom and standard identity providers (e.g. Keycloak and AWS Cognito), and federation patterns.
• Mentor engineers, conduct design reviews, and contribute to the team's technical roadmap and security posture.

Qualifications

• 7+ years of backend engineering experience, including 5+ years with Go
• 3–4+ years working with authentication, authorization, SSO, MFA, OAuth 2.0, OpenID Connect, JWT, and session management in production environments
• Strong production experience with Go and gRPC; building complex distributed backend systems
• Deep knowledge of authentication and authorization: OAuth2, OIDC, RBAC, JWT, token security, session management, cryptography
• Strong understanding of web security, federated identity, secure coding, and OWASP Top 10
• Hands-on experience with AWS, Kubernetes, and Terraform
• Experience designing high-throughput, low-latency systems with a focus on security and correctness
• Strong communication skills; able to explain security and architecture trade-offs to technical and non-technical stakeholders

Requirements

• Experience with SAML, SCIM, PKI, JWKs/JWKS endpoints, key management (KMS/HSM) and token introspection.
• Working knowledge of identity platforms (commercial or open source), rate limiting, abuse mitigation, and adaptive authentication.
