Senior IT Engineer

About this role

We are seeking an experienced and driven Senior IT Engineer to serve as a senior technical contributor on Posit's IT Operations team, supporting our distributed workforce, corporate systems, and enterprise AI infrastructure. The ideal candidate is a seasoned systems administrator and support engineer who has moved beyond day-to-day ticket response and is ready to take ownership of critical platforms, lead cross-team technical efforts, and mentor more junior team members. You'll play a leading role in operating our IT infrastructure, raising the bar on our processes and documentation, and ensuring the productivity and security of our employees. IT Operations owns and runs the platforms everything else rides on — identity, endpoints, SaaS systems, the enterprise AI platform, and the infrastructure for our enterprise automation platform. Our department's mission is to empower Posit's employees with reliable technology, maintain a robust IT environment, and operate the platform foundation for the company's enterprise AI program. You will collaborate closely with other teams across the organization to achieve our departmental mission. We achieve this through proactive system management, responsive user support, code-driven operations, and continuous process improvement, enabling innovation with effective IT solutions. Since its inception, Posit has operated as a 100% distributed company with a SaaS-first infrastructure, complemented by select platforms we host and manage ourselves in AWS. This presents unique challenges and requires pragmatism, creativity, and a collaborative, detail-oriented approach to be successful.

You will own:

• End-to-end ownership of one or more core IT platforms (platforms such as Okta, Google Workspace, Jamf Pro, Zoom, Slack, or the infrastructure for automation platforms such as n8n, Workato, or Okta Workflows) — including configuration, health, security posture, and roadmap. For the automation platform, that means the platform itself — hosting, upgrades, access, backups, and monitoring — while IT Engineering builds the workflows within it. While most of our stack is SaaS, some platforms are self-hosted in AWS, and that infrastructure is ours to run.

• Complex technical escalations across end user devices (Mac, Windows, Linux) and SaaS applications, serving as the senior point of contact when issues exceed the scope of Tier 1 support.

• Design and implementation of meaningful improvements to employee technology workflows — onboarding, offboarding, device lifecycle, access provisioning with scalability at the forefront.

• Day-to-day operational ownership of Posit's enterprise AI platform and its supporting integrations, including SSO/SCIM health, license management, desktop deployment via MDM, and front-line support for complex issues.

• Technical mentorship of IT Engineers — pairing on tickets, reviewing pull requests, and leveling up the team's technical practices.

• Maintenance of SaaS configurations, end user device controls, system access controls, and patch management according to approved guidelines, with a high bar for security and compliance.

• Creation and upkeep of technical documentation, runbooks, and playbooks for the systems and processes you own.

• Leading scheduled audits of IT-controlled systems and coordinating remediation of findings.

• Driving IT's GitOps practice forward — managing meaningful portions of your owned systems through version-controlled code, pull requests, and peer review, and coaching others through the same workflow.

You will assist with:

• Defining and refining IT's engineering standards, including IaC patterns, code review expectations, and exception processes.

• Contributing to procurement, vendor evaluation, and technical assessments for new tools — with a clear eye toward automation, support for configuration as code, and integration with our existing stack.

• Enforcing procedures for safeguarding information security and safety within IT procedures.

• Tracking hardware/software assets (licenses, warranties, accounts); identifying capacity and spending trends before they become problems.

• Responding to internal and external audit requests in partnership with GRC and Security.

• Operating and supporting the rollout of approved MCP integrations and AI workflows built by IT Engineering — owning the identity, access, deployment, and monitoring layers they depend on.

• Recommending and implementing IT process improvements, with a bias toward automation over manual toil.

About you:

• You have significant progressive IT experience, with meaningful time spent as a system administrator or engineer in a SaaS-first or distributed environment.

• You thrive on solving problems through investigation and deductive reasoning, and you know when to escalate, when to dig in, and when to step back and redesign.

• You invest in strong relationships with your colleagues and employ empathy when working through their technical issues. You can translate complex technical topics for non-technical audiences, and you can hold your own with security, engineering, and legal stakeholders.

• You are self-driven, demonstrate initiative, and maintain a high degree of professional conduct at all times.

• You are highly ethical, possess excellent decision-making capabilities, and execute good time management skills.

• You question assumptions, drive change to mitigate potential risks, and possess excellent documentation skills.

• You have deep working knowledge of corporate technologies — identity providers, MDM platforms, productivity suites, and endpoint security tooling — platforms such as Okta, Jamf Pro, Microsoft Intune, Fleet, Google Workspace, Slack, and Zoom.

• You are highly proficient with multiple versions of macOS, Linux, and Windows operating systems and have hands-on experience administering mobile device management platforms at scale (platforms such as Jamf Pro, Microsoft Intune, or Fleet).

• You have strong working
