About the Role

We run IT across a portfolio of ten companies from three-person startups to larger organizations with hundreds of contractors and accounts to administer and support and we operate as a small, senior team that punches well above its weight. This role is in the critical path of how our portfolio companies operate. When things work, CEOs and their teams move fast.

When things’t, everything slows down. This is more than support. It’s operations, troubleshooting, and scripting in service of businesses that need to keep moving. IT here operates as a strategic partner to the business, not a help desk function and the people on this team are expected to think that way. That means we’ll bring you into context about what each company does, how they operate, and what matters to them because the best solutions come from someone who actually understands the business they’re supporting, not just the tools.

The

Environment
  • Ten portfolio companies, ranging from three-person startups to larger organizations with hundreds of contractors and accounts each at a different stage, with different needs and different levels of structure
  • Cloud-first, SaaS-native stack no legacy infrastructure, no on-prem drama
  • Small IT team you’ll have real ownership and direct visibility into decisions, not a layer of managers between you and the work
  • Fully remote we operate asynchronously across time zones, but also move fast when something needs to move fast. Strong written communication and self-direction are non-negotiable.
  • Active M&A environment we stand up IT for new entities and manage migrations when companies are divested. You’ll see work here that most IT roles never touch.
What You’ll Own Cross-Portfolio Support
  • Serve as a primary technical resource across the portfolio, handling escalated issues that require real judgment not just a runbook
  • Adapt your approach to each company’s size and maturity: a 3-person startup and a larger org with hundreds of accounts need different energy and different solutions
  • Own the full laptop lifecycle across the portfolio procurement, provisioning, MDM enrollment, and ongoing endpoint management
  • Research technology options and put together recommended paths forward when a CEO or stakeholder has a problem that doesn’t have an obvious solution over time, you’ll have increasing autonomy to make those calls independently
  • Collaborate directly and proactively with engineering teams not as an escalation path, but as a natural part of how you work when problems cross into platform or Dev Ops territory
Identity & Access Management
  • Make sure the right people have access to the right things and that the wrong people don’t. That means owning onboarding, offboarding, and role changes across every company in the portfolio
  • Be the person who gets called when someone can’t get in, has too much access, or needs something changed fast
  • Manage RBAC, SSO, and SCIM provisioning across platforms Jump Cloud is our primary identity provider
  • Troubleshoot authentication issues across our SaaS stack and keep access changes aligned with least-privilege without making it harder for people to do their jobs
SaaS Platform Administration
  • Administer and troubleshoot our core platforms:
    Google Workspace, Jump Cloud, Slack, Crowd Strike, Halo ITSM, and the SaaS tools integrated across the portfolio
  • Own platform configuration, integration troubleshooting, and access reliability
  • Be the person who actually understands how these systems talk to each other
Operational Improvement
  • When you see something broken or repetitive, fix it don’t just log it
  • Write and maintain documentation and runbooks that actually get used
  • Build small automations and scripts when the manual alternative is a waste of everyone’s time
  • Bring ideas to the team; this is a small group and good thinking gets acted on
Experience What We’re Looking For
  • 2–4 years in IT operations, systems support, or a similar role in a SaaS-forward environment
  • Hands‑on experience with identity platforms Jump Cloud, Okta, Azure AD, or similar
  • Solid understanding of SSO protocols (SAML, OAuth, OpenID Connect) and SCIM provisioning
  • Experience with RBAC and access governance in practice, not just in…
