About The Position

Postman is seeking a Senior Mac Systems Engineer to lead the management, automation, and evolution of its macOS endpoint fleet. This role focuses on treating endpoint management as a platform engineering problem, emphasizing declarative, version-controlled, and reproducible systems. The engineer will own the entire Mac fleet lifecycle, from procurement to retirement, and will partner with Security and GRC teams on CMMC Level 2 readiness. A key aspect of the role involves evaluating and re-architecting the endpoint stack, and thoughtfully integrating AI and agentic systems into IT operations. This is a strategic role for an individual with a strong automation instinct and a forward-thinking approach to IT operations.

Requirements

7+ years managing macOS at scale in a fast-moving engineering organization, including deep production experience with at least one major MDM (Jamf, Kandji, Mosyle, SimpleMDM, Workspace ONE, or similar).
A strong automation instinct. You see manual work as a bug, you reach for code before consoles, and you've built the kind of automation other people on your team rely on daily.
Practical experience applying AI and LLM-based tooling to real IT and operations problems. You've used Claude Code, Cursor, or similar agentic tools in your own workflow, and ideally you've built or deployed agentic workflows that other people use.
Strong scripting and software development skills. You're comfortable in Python, Go, Bash, or Swift, and you write code that other engineers would be willing to review.
Hands-on experience with infrastructure as code and modern DevOps practices: Terraform, Git-based workflows, CI/CD, code review, and treating production changes as software changes.
Working knowledge of endpoint telemetry and device trust tooling: osquery, Fleet, Kolide, Munki, AutoPkg, or comparable open-source ecosystems.
Deep understanding of Apple's management surface area: declarative device management, MDM protocol, configuration profiles, FileVault, Gatekeeper, system extensions, and the ongoing implications of Apple Silicon.
Experience running a macOS hardware lifecycle program at scale: forecasting, procurement, asset management, refresh planning, and end-of-life logistics.
Identity and access fluency: Okta, SSO, SCIM, certificate-based authentication, and how identity intersects with device posture.
A track record of replacing manual or vendor-locked workflows with automated, observable, and testable systems.
Excellent written communication. You can write a clear RFC, a vendor evaluation, or a runbook that someone three years from now will still understand.

Nice To Haves

Active participant in the MacAdmins community, Penn State Slack, MacDevOpsYVR, MacSysAdmin, or similar.
Open-source contributions to projects like Munki, Nudge, AutoPkg, osquery, Fleet, swiftDialog, or your own published tooling.
Experience building or deploying agentic AI workflows in a production IT or operations context, including the unglamorous parts: evaluation, guardrails, cost control, and failure modes.
Experience standing up or significantly improving a Zero Trust device-trust program.
Background supporting compliance frameworks such as CMMC, SOC 2, ISO 27001, or FedRAMP.
Familiarity with managing Windows or Linux endpoints alongside Mac (Intune, Jamf Pro for iOS, Fleet on Linux).
Experience integrating endpoint data into a broader security data lake or SIEM.

Responsibilities

Own Postman's macOS fleet management strategy and execution: provisioning, configuration, patching, telemetry, and lifecycle.
Treat infrastructure as code. Manage endpoint configuration, automation, and integrations through version-controlled, peer-reviewed code rather than clicking through admin consoles.
Lead automation as a first-class engineering discipline. Identify the highest-leverage manual workflows in IT and replace them with reliable, observable, testable automation.
Apply AI and agentic systems pragmatically across IT operations: triage, remediation, knowledge surfacing, vendor analysis, and developer self-service. Decide where these tools belong, build the guardrails, and measure the outcomes.
Own the macOS hardware lifecycle end to end: demand forecasting, procurement strategy, depot and inventory operations, refresh cycles, warranty and AppleCare programs, and responsible end-of-life and sustainability practices.
Continuously evaluate our endpoint stack. Identify where current tooling is holding us back, prototype alternatives, and lead migrations when the data supports it.
Build internal tooling where vendors fall short: inventory pipelines, compliance reporting, automated remediation, and self-service workflows for engineers.
Partner with Security, GRC, and IT Operations to deliver controls that satisfy CMMC Level 2 and other compliance frameworks without slowing developers down.
Design and operate the telemetry layer for endpoint visibility: osquery, Fleet, Kolide, or whatever combination best fits the problem.
Mentor IT Systems Administrators and partner with adjacent teams (Security Engineering, DART, Procurement) on cross-functional initiatives.
Be the senior technical voice in vendor evaluations, contract negotiations, and architecture decisions for anything touching the Mac fleet.
