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 lifecycle of Mac devices, from procurement to retirement, and will collaborate with Security and GRC teams on CMMC Level 2 readiness. The position also involves evaluating and integrating AI into IT operations, distinguishing between useful automation and hype. The ideal candidate will have a strong automation instinct, experience with MDM vendors, and a desire to improve systems through code.

Requirements

7+ years managing macOS at scale in a fast-moving engineering organization.
Deep production experience with at least one major MDM (Jamf, Kandji, Mosyle, SimpleMDM, Workspace ONE, or similar).
A strong automation instinct; reaching for code before consoles.
Practical experience applying AI and LLM-based tooling to real IT and operations problems.
Strong scripting and software development skills (Python, Go, Bash, or Swift).
Hands-on experience with infrastructure as code and modern DevOps practices: Terraform, Git-based workflows, CI/CD, code review.
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 Apple Silicon implications.
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.
A track record of replacing manual or vendor-locked workflows with automated, observable, and testable systems.
Excellent written communication skills (RFCs, vendor evaluations, runbooks).

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 own published tooling.
Experience building or deploying agentic AI workflows in a production IT or operations context.
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, managing endpoint configuration, automation, and integrations through version-controlled, peer-reviewed code.
Lead automation as a first-class engineering discipline, identifying and replacing manual workflows with reliable, observable, testable automation.
Apply AI and agentic systems pragmatically across IT operations: triage, remediation, knowledge surfacing, vendor analysis, and developer self-service.
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 the endpoint stack, identifying limitations, prototyping alternatives, and leading migrations.
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.
Design and operate the telemetry layer for endpoint visibility using tools like osquery, Fleet, or Kolide.
Mentor IT Systems Administrators and partner with adjacent teams on cross-functional initiatives.
Act as the senior technical voice in vendor evaluations, contract negotiations, and architecture decisions for the Mac fleet.
