Senior Level Infrastructure Platform Engineer Jobs

INTRODUCTION

A Senior Platform Engineer / Cloud Infrastructure Engineer with strong AWS, Linux/Windows administration, AMI management, Python, Python automation, Infrastructure Architecture, and Platform Engineering experience. The ideal candidate combines system engineering and software development skills, can support enterprise-scale cloud environments, build compliant OS images, automate processes using Python, and troubleshoot infrastructure issues across AWS platforms.

BASIC QUALIFICATIONS

Must have:

- AWS
- Linux Administration
- Python Automation
- Ansible
- Python API Integration
- Infrastructure Engineering
- AMI / Image Management, Image building

Job Family Description:

- Significant experience in both Systems Engineering and Software development
- Proficient in at least one of the infrastructure disciplines and functions:
- Internals of distributed Operating System (Unix/Linux, Windows, Z/OS) internals
- Systems programming
- Network programming
- Experience in large scale software development in one or more of the programming languages (C, C++, Perl, Python, Java, C#, .NET)
- Enterprise scale and resiliency
- Experience in system and software security and entitlements (SSO, windows, Kerberos, LDAP, Windows AD)
- Modern compute technologies (e.g., virtualization, cloud)
- Experience with Agile development process and automated testing
- Experience working across large infrastructure environments and distributed across multiple data centers
- Experience in end-to-end systems automation and orchestration
- Experience in Systems and Application monitoring systems and instrumentation

ROLE AND RESPONSIBILITIES

Public Cloud Infrastructure team is looking for a strong candidate to join them in producing Virtual Machine Images and orchestrating distribution to thousands of subscribers in Public Clouds.

The role:
We build the automated platform that produces hardened, compliance-tested operating system images (AWS AMIs) for a large enterprise cloud estate. Every image our internal teams launch — across RHEL, Windows, macOS, and Amazon Linux — is created, customized, security-tested, and distributed by the systems this team owns, spanning multiple AWS regions and multiple environments. We maintain hundreds of image definitions and customization packages, including ARM/x86, GPU, and Kubernetes (EKS/ECS) node variants.

As a cloud infrastructure senior engineer, you'll set technical direction across two connected sides of the platform:
- Platform / Infrastructure — event-driven build pipelines using AWS Step Functions and Lambda, defined as Infrastructure as Code in CloudFormation, orchestrating the full image lifecycle from import through customization, testing, distribution, and decommissioning.
- Image customization & operations — the reusable packages, Ansible provisioning scripts, and compliance tests that define each image, delivered through a PR-driven, automated release pipeline.

What you'll do:
- Own and evolve serverless, event-driven build automation (Step Functions, Lambda, SNS, S3, EC2) that customizes machine images at scale.
- Lead Infrastructure as Code (CloudFormation) that deploys consistently across many regions and accounts.
- Build and harden OS images for RHEL, Windows, macOS, and Amazon Linux, including GPU, ARM64, and Kubernetes node variants, to strict security and compliance standards.
- Raise the bar on code quality, test coverage, and CI/CD health; mentor engineers and lead technical reviews.
- Partner with OS engineering and consuming application teams to keep the image catalog secure, current, and reliable.

PREFERRED QUALIFICATIONS

- 7+ years in infrastructure, platform, or cloud engineering, with strong hands-on AWS experience (EC2/AMIs, Lambda, Step Functions, CloudFormation, IAM, S3, SNS).
- Custom VM Image building skills.
- Google and Azure experience is a plus.
- Hands-on experience in creating complex AI skills, agents.
- Strong Python and a solid automated-testing discipline.
- Proven ownership of production Infrastructure as Code and CI/CD pipelines, ideally multi-region/multi-account.
- Linux and/or Windows administration and OS hardening experience; macOS a plus.
- Configuration management (Ansible) and compliance-as-code testing (InSpec) strongly preferred.
- Demonstrated technical leadership and mentoring.

WHY JOIN

This is platform engineering with real reach: thousands of workloads boot from the images this team produces. You'll build both the automation and the product it delivers, and ship to production on a regular cadence.
