The Role

We're looking for a Cloud Platform Engineer to own the internal IT infrastructure Mercor runs on — and to run it as code. You'll design and operate the platform layer beneath our identity, cloud, and SaaS systems: Okta configuration managed in Terraform, cloud IAM and account structure defined declaratively, and employee lifecycle provisioning automated end to end. You'll also own identity planning as we scale from hundreds to thousands of employees. This role reports directly to the Head of IT and is critical to our operational foundation.

- Own Mercor's identity infrastructure — Okta configuration and provisioning — managed as code in Terraform rather than clicked through a console
- Design and implement SCIM integrations across our SaaS stack, automating user provisioning and deprovisioning
- Own identity planning and architecture as we scale: access models, group strategy, and how entitlements evolve from hundreds to thousands of employees
- Own cloud account structure, IAM roles, and permission boundaries across AWS, GCP, Azure, and Vercel, keeping access least-privilege as the org grows
- Build and maintain Terraform for internal platforms so environments are reproducible and every change is reviewable
- Build automation that cuts manual ticket volume for employee onboarding and offboarding
- Design and own secrets management, key rotation, and service-account lifecycle
- Troubleshoot identity and infrastructure issues, trace root causes, and implement systemic fixes
- Document platform architecture, runbooks, and automation so the team can operate and extend it
- Mentor future IT team members on infrastructure-as-code, automation practices, and systems thinking
- Help establish sustainable escalation procedures as the team grows

You may be a good fit if you have:

- Hands-on production experience with Terraform, managing real infrastructure as code
- Production experience with Okta and SCIM integrations — ideally managed declaratively
- Strong skills with IAM roles and permissions across at least two major cloud platforms — AWS, GCP, or Azure — with Vercel a plus
- Proficiency in at least one programming language with demonstrated understanding of core coding principles
- Experience building automated workflows across systems via APIs
- Strong incident management skills: triage, root-cause analysis, and systems thinking
- Strong documentation skills — able to write technical guides other team members can follow and learn from
- Clear communication skills — able to explain technical identity and infrastructure concepts to non-technical stakeholders
- A systems-thinking mindset that naturally traces dependencies and considers second-order effects
