🎯 The Role

As an Internal Platform Engineer, you will own and evolve the internal tooling and enterprise platforms that keep a 300+ person, globally distributed company running securely and productively. This is not a helpdesk role — you'll be the engineering backbone behind identity & access management, corporate email and collaboration, device management, SaaS orchestration and our centralised AI/LLM gateway. You'll ensure that every team at HTB has the right tools, properly integrated, secured and automated.

✅ Key Responsibilities

• Administer and engineer Okta as the central identity provider: SSO integrations, SCIM provisioning/de-provisioning, MFA policies, Okta Workflows for lifecycle automation (onboarding, offboarding, role changes)
• Own Google Workspace administration: domain management, email routing and security policies (DKIM/DMARC/SPF), shared drives governance, DLP rules and Google Vault for eDiscovery/retention
• Deploy and operate a centralised LLM gateway (e.g. LiteLLM, Portkey) to give teams governed access to AI models with usage tracking, cost controls, rate limiting and audit logging
• Manage endpoint fleets via Jamf Pro (macOS/iOS): OS patching, app deployment, compliance baselines, disk encryption enforcement
• Operate and improve compliance automation tooling (Vanta/Drata) to maintain continuous SOC 2, ISO 27001 and similar audit readiness
• Administer SaaS platforms at the org level: Slack (Enterprise Grid), Atlassian suite, Notion, GitHub (org/team/repo policies, SAML)
• Maintain documentation, runbooks and internal knowledge-base articles so that common procedures are self-service where possible
• Participate in on-call rotation for identity, email and critical SaaS platform incidents

📌 Required Qualifications

• 3–7 years of professional experience in IT engineering, internal platform engineering or infrastructure with a strong focus on enterprise SaaS and identity systems
• Deep hands-on experience with Okta including SSO, SCIM provisioning and MFA policy management
• Strong Google Workspace administration skills (domain management, email security, DLP, Vault)
• Experience managing macOS fleets at scale using Jamf
• Comfortable writing automation scripts (Go/Python) and working with APIs to integrate SaaS tools
• Ability to translate security and compliance requirements (SOC 2, ISO 27001) into practical engineering controls
• Strong written communication for documentation, runbooks and cross-team collaboration in a remote-first environment
• Being cyber security-minded is a strong plus — at HTB, this isn't an afterthought, it's the business

⭐ Desirable Experience

• Experience deploying and operating a centralised LLM/AI gateway (LiteLLM, Portkey, Kong AI Gateway or equivalent) with cost and access controls
• Familiarity with compliance automation platforms (Vanta, Drata, Secureframe)
• Understanding of Go/Python for building internal tooling
• Okta Certified Professional or Administrator, Google Workspace Administrator certification, or equivalent
• Experience scaling internal platforms through a period of rapid company growth (100 → 500+ employees)
