We are looking for a Senior Identity and Access Management (IAM) Engineer to play a critical role in designing, implementing, and maturing our enterprise IAM ecosystem. As a Senior IAM Engineer, you will serve as a key subject matter expert (SME) within the broader Information Security organization, driving secure, scalable, and user-friendly identity solutions in a fast-paced, high-growth environment. You will own complex IAM initiatives end-to-end — from strategy and architecture to implementation and optimization — while collaborating closely with Security, Infrastructure, Application, and Engineering teams. This is a high-impact, hands-on role suited for someone who thrives in ambiguity and takes extreme ownership of outcomes.
RESPONSIBILITIES:- Design and implement enterprise-grade IAM solutions across on-prem, cloud, and SaaS environments.
- Architect and deliver end-to-end federation strategies using modern protocols (SAML, OIDC, OAuth 2.0, SCIM).
- Lead integration and optimization of key IAM platforms including SailPoint, Okta, PingOne, Microsoft Entra ID, and other tools.
- Drive Identity Lifecycle Management (LCM), Role-Based Access Control (RBAC), Privileged Access Management (PAM), and Just-In-Time access initiatives.
- Develop automation scripts and Infrastructure as Code (Terraform) to improve provisioning, governance, and operational efficiency.
- Serve as the primary IAM SME, providing technical guidance, troubleshooting complex issues, and mentoring other team members.
- Work closely with InfoSec, Compliance, and Engineering teams to meet audit, regulatory, and security requirements.
- Continuously improve IAM architecture, processes, and capabilities in a dynamic, fast-moving organization.
- Support cloud IAM strategies across AWS, GCP, and other platforms.
- Participate in on-call rotation and incident response related to identity systems.
- 6+ years of hands-on experience in Identity and Access Management.
- Thorough understanding of IAM principles and modern security concepts, including Zero Trust, Least Privilege, Adaptive/Risk-Based Authentication, Attribute-Based Access Control (ABAC), Continuous Access Evaluation, and Identity Threat Detection and Response (ITDR).
- Strong expertise in IAM protocols and standards: SAML, OIDC, OAuth 2.0, SCIM, and other federation protocols.
- Strong expertise in IAM and federation protocols, with proven experience in architecting and implementing end-to-end federation solutions.
- Hands-on experience with major IAM platforms, particularly SailPoint, Okta, PingOne, and Microsoft identity solutions.
- Strong working knowledge of cloud platforms (AWS and GCP), Cloud IAM services, Terraform, and CI/CD practices.
- Strong scripting and programming skills in Python and JavaScript/TypeScript, with extensive experience developing IAM workflows, automation, and integrations.
- Demonstrated ability to lead technical initiatives and drive projects from design through implementation.
This high-visibility role requires the ability to thrive in a fast-paced and ambiguous environment. The ideal candidate demonstrates extreme ownership, a collaborative no-ego mindset, and is comfortable taking the lead. This is a significant opportunity to shape the future of identity and security at the company.
