Ready to embark on the quest of joining Hack The Box? Welcome! Super excited you dropped by. At the end of this journey, you'll become a proud member of Hack The Box, with the ultimate mission to raise cyber resilience, so that every organization can stay ahead of tomorrow’s threats.
The core mission of the Senior IT Platform Engineer: 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.
Engineer, integrate and operate HTB's internal platform stack — from identity (Okta) and email (Google Workspace) through endpoint management (Jamf) to our centralised LLM gateway — so that the company scales securely without friction.
Location & Work Mode: Europe/Greece Choose between fully remote work across Europe or relocating to our Athens Tech Hub with relocation support. Fully Remote / Hybrid (2 days in the office, 3 days remote, plus one month of work from anywhere) - If only in Greece: When hiring in Greece, we’re open to candidates from all locations. Those based within 55 km of our Athens office will follow a hybrid work model. For candidates located beyond that radius, a fully remote arrangement is available.
Relocation We offer a 10% relocation bonus on the annual salary to support your move. In addition, you would benefit from a 50% tax reduction on your income as part of the relocation. We'll support you with accommodation during the first few weeks.
Tools & Weapons You’ll Be Using:
- Identity & Access: Okta (SSO, SCIM, Lifecycle Management, Okta Workflows), Google Workspace (Gmail, Drive, Admin Console)
- Endpoint & Device Management: Jamf Pro (macOS/iOS)
- AI / LLM Gateway: LiteLLM or Portkey (centralised LLM routing, cost controls, audit logging), API key management
- Collaboration & Productivity: Slack, Atlassian (Jira, Confluence), Notion, GitHub (org-level administration)
- Automation & Integration: Okta Workflows, Terraform, Python scripting
The adventures that await you after becoming Senior IT Platform Engineer at Hack The Box:
- 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
Skills, knowledge, and experience points required to unlock the role of Senior IT Platform Engineer at Hack The Box:
- 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

- 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
Bonus Points:
- 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
