Lantern is the specialty care platform, connecting people with high-quality, affordable specialty care close to home. We operate in a regulated healthcare environment (HIPAA, HITRUST, SOC 2), we handle protected health information at scale, and we are becoming an AI healthcare company, with AI adoption a top company priority.

This Principal IAM Engineer is a senior level, individual-contributor role and the technical authority for identity at Lantern. In an organization where the security perimeter is effectively identity, you will own the identity control plane end to end, and you will determine who can reach PHI and under what conditions. You will set the identity standard, build the automation behind it, and hold the verification bar that other teams operate against.

You will report to the CISO and partner closely with our IAM engineer and with the platform, cloud, and service delivery teams that execute alongside you. This is a hands-on principal seat, not a people-management role today, with a clear path to expand into a leadership role as the identity function grows.

Our security philosophy is open by default, secure by design. Security exists to help the business move fast, safely, and the default answer is “yes, safely,” because guardrails are built into the platform, pipelines, and tooling rather than enforced by someone saying no. Gates exist only where risk genuinely warrants them, and even then they are automated, fast, and transparent.

Location: Hybrid - at least 3 days/wk in our Dallas, TX offices

Responsibilities:

• Own the identity lifecycle: joiner, mover, and leaver provisioning and deprovisioning, automated from role- and attribute-based models (RBAC/ABAC), with deprovisioning verified against an entitlement inventory rather than assumed.

• Own access management, including Conditional Access, phishing-resistant MFA, and privileged access on a Zero Trust model, with least-privilege by default, just-in-time (JIT) elevation, and enforcement confirmed on every access path rather than only saved.

• Own directory and federation across Entra ID, single sign-on, SAML, OIDC, and OAuth2.

• Own secrets and non-human identity, including API keys, service accounts, and workload identity, and maintain an owner registry for them.

• Own key access governance and separation of duties in a model where another team operates the key management system.

• Own identity automation and identity-as-code, building lifecycle and access controls as reviewable, version-controlled infrastructure (Terraform and policy-as-code) rather than manual configuration.

• Own the identity-verification standard the service desk follows for password resets, MFA resets, and device enrollment. This is a hands-on control point, because helpdesk-initiated resets are a leading account-takeover vector.

Key Deliverables in Your First Year:

• Conditional Access enforced by default on PHI-facing applications, with enforcement verified.

• Automated joiner, mover, and leaver provisioning and deprovisioning that meets its SLA every time.

• A secrets golden path, with vaulted secrets, none in code, and a populated key-to-owner registry.

• Strong, phishing-resistant MFA coverage on privileged accounts.

• Documented runbooks and depth across the control plane, so no critical control depends on a single person.

How You Will Work:

You will set standards that partner teams execute. Service Delivery performs provisioning tasks and resets against the verification bar you own. Cloud Engineering carries cloud access, workload identity, and key-management operations, with key access governed by you. HR events are the sole trigger for lifecycle changes. The Governance, Risk & Compliance team independently attests to the entitlements you produce, and access certification deliberately sits outside this role so that the team reviewing access is not the team granting it. Holding those boundaries cleanly is central to the job.

Requirements:

• Eight or more years in identity and access management, including principal- or staff-level ownership of an identity control plane.

• Deep Microsoft Entra ID engineering, including Conditional Access policy design, phishing-resistant MFA, single sign-on, and federation across SAML, OIDC, and OAuth2, and verifying that enforcement takes effect across every access path, not only the expected one.

• Identity lifecycle automation across cloud, SaaS, and privileged systems, with role- and attribute-based provisioning (RBAC/ABAC) and deprovisioning verified against an entitlement inventory.

• Zero Trust identity design, including least-privilege, just-in-time (JIT) access, and risk-based or adaptive access controls.

• Identity governance and administration (IGA) platform engineering, including privileged access management.

• Automation and scripting (PowerShell, Python, or similar) to build lifecycle workflows and custom connectors.

• Identity-as-code and policy-as-code practice, using Terraform with source-controlled change management (for example, GitHub).

• Secrets and non-human identity (API keys, service accounts, workload identity), and maintaining an owner registry fo
