Job Description

Collaborate with Innovative 3Mers Around the World

Choosing where to start and grow your career has a major impact on your professional and personal life, so it’s equally important you know that the company that you choose to work at, and its leaders, will support and guide you. With a wide variety of people, global locations, technologies and products, 3M is a place where you can collaborate with other curious, creative 3Mers.

This position provides an opportunity to transition from other private, public, government or military experience to a 3M career.

The Impact You’ll Make in this Role

As a Platform / DevSecOps Engineer - Secure AI Systems, you will be the principal hands‑on owner of the secure platform foundation for a new-to-the-world AI architecture. You will design, build, automate, operate, secure, and ensure recoverability of an evolving environment that spans isolated cloud networks, hybrid infrastructure, and a future fully air‑gapped on‑premises platform. Working in partnership with the program's senior technical team, you will establish the foundation early, shape architecture decisions, and remain directly accountable for how the platform performs in real environments. Architecting and implementing scalable runtime components for real‑time inference, near‑real‑time reasoning, large offline simulations, cloud services, on‑premises deployments, and embedded or edge environments.

• Own the end‑to‑end operation of business‑critical collaboration and software‑development platforms, including the compute, storage, networking, database, and runner infrastructure supporting isolated and air‑gapped environments.
• Establish, build, and operate the secure platform foundation, with accountability for availability, performance, capacity, cost, maintenance, and day‑to‑day reliability.
• Design and enforce Zero Trust boundaries across public, quarantine, DMZ, cloud, on‑premises, developer, and internal application environments using segmentation, least‑privilege access, and controlled ingress and egress.
• Administer GitHub Enterprise Server, including repositories, permissions, episodic Actions runners, audit logs, upgrades, backups, and disaster‑recovery configurations.
• Integrate identity, privileged‑access, secrets, key, and certificate services using federation, SAML, OIDC, RBAC, conditional access, credential rotation, and lifecycle controls.
• Design, develop and operate a controlled software‑supply‑chain pipeline that scans, validates, traces, and securely promotes trusted source code, packages, containers, firmware, and other artifacts into protected environments.
• Engineer geographically redundant backup, replication, restore, and failover capabilities across cloud and on‑premises environments, with recovery proven through routine testing.
• Automate, monitor, and continuously secure the platform using reusable Terraform modules, scripting, centralized observability, vulnerability remediation, threat modeling and hunting, security reviews, threat detection.
• Lead major incident‑response activities, including investigation, containment, recovery, root‑cause analysis, and implementation of corrective actions.

To set you up for success in this role from day one, 3M requires (at a minimum) the following qualifications:

• Bachelor’s degree or higher in computer science, computer engineering, cybersecurity, or information systems (completed and verified prior to start)
• High School Diploma/GED (completed and verified prior to start) and seven (7) years of experience building, operating, automating, securing, or recovering business‑critical technology platforms and infrastructure.
• Seven (7) years of professional experience in platform engineering, DevSecOps, site reliability engineering, cloud infrastructure, infrastructure security, or a related field.
• Three (3) years of hands on experience designing, deploying, and operating infrastructure using Terraform across public cloud (AWS, Azure, GCP) and private cloud/virtualization technologies (e.g., OpenStack, VMWare).
• Three (3) years of production experience administering GitHub Enterprise Server or a comparable self‑hosted software‑development platform, including identity, permissions, automation runners, audit logging, upgrades, backup, and recovery.
• Three (3) years of scripting and software‑development capability using scripting languages like Python, Bash, and/or PowerShell, with disciplined use of source control, code review, testing, release management, and documentation.
• Hands‑on experience designing, deploying, and managing highly scalable Kubernetes environments.
• Hands‑on experience building greenfield infrastructure platforms and operating critical systems in air‑gapped, disconnected, or highly isolated production environments.
• Experience serving as the technical owner of mission‑critical production enterprise platforms supporting multiple engineering teams, including responsibility for architecture decisions, operational readiness, reliability, security, and disaster recovery.
• Experience deploying and operating physical infrastructure, including servers, storage, networking, and virtualization platforms.
• Experience designing and implementing systems that protect sensitive intellectual property or regulated information in environments such as trade‑secret‑intensive research, government, defense, healthcare, critical infrastructure, classified, or export‑controlled programs.
• Experience implementing and maintaining compliance controls aligned with cybersecurity frameworks such as NIST CSF, FedRAMP, CMMC, DoD STIGs, or comparable security standards.
