Job description

We are seeking a deeply technical, highly autonomous, and analytically exceptional Senior Engineer - Windows Platforms to join our global technology organization. This is a hybrid role that requires working at least three days a week in the office.

This role is for a true technical heavy hitter who thrives at the intersection of traditional enterprise infrastructure and cutting-edge DevOps methodologies. You will not merely support environments; you will design, build, and automate them from first principles. Operating at a senior level with minimal supervision, you will be expected to untangle unprecedented technical complexities, identify underlying systemic patterns, and drive project initiatives across a massive global footprint.

As a Senior Engineer, your technical authority will be relied upon heavily during high-stakes operational events and transformative corporate cloud initiatives. You must possess the maturity to influence cross-functional teams without formal authority, the intellectual agility to synthesize vast amounts of multi-system data in real-time, and an uncompromising passion for the evolving technology landscape. If you live and breathe technology, possess exceptional communication capabilities, and command the advanced scripting and infrastructure-as-code capabilities required to engineer immutable Windows environments at an enterprise scale, we invite you to join our team.

We will count on you to:

• Lead Critical Incident Responses: Take a lead role on Major Incident conference calls. You will use your exceptional analytical acuity and outstanding communication skills to direct, influence, and drive rapid resolution across global, cross-functional engineering teams (including Network, Storage, Database, and Security).
• Drive Strategic Cloud Migrations: Serve as an authoritative voice and technical anchor for Windows workloads during large-scale, highly complex cloud migration initiatives.
• Architect and Build Complex Systems: Independently design, engineer and deploy highly resilient, multi-system Windows environments. You will map complex system dependencies and ensure infrastructure is built to stringent scalability and security baselines.
• Build Automation and Infrastructure as Code (IaC): Eliminate manual operational tasks by writing advanced scripts and deploying sophisticated automation pipelines. You will leverage PowerShell as a core development language to automate complex server support, configuration management, and immutable server builds.
• Operate with Extreme Autonomy: Function as a mature, self-directed leader within the engineering domain. While this role does not involve direct personnel management, it carries the expectations of a Team Leader level role, requiring you to mentor peers, define global technical standards, and execute large-scale projects flawlessly.

What you need to have:

• Exceptional Communication: Strong English language skills (both spoken and written) are strictly required. You must be highly capable of articulating highly abstract technical concepts to both engineering peers and global business stakeholders across multiple time zones.
• Deep Windows Mastery: Expert-level knowledge of Windows Server architecture (2016 through 2025), failover clustering, advanced networking stacks, and Active Directory Domain Services within massive, geographically dispersed enterprise environments.
• Automation & Coding: Hands on experience working with Git and PowerShell. Proficient in writing and reviewing clear, clean and concise scripts and code with version control methodologies.
• DevOps & CI/CD Proficiency: Hands‑on experience integrating Windows infrastructure into modern continuous delivery pipelines using tools such as Azure DevOps, GitHub Actions, or Jenkins to deploy infrastructure as software.
• Cloud Fluency: While grounded heavily in Windows platforms, you must operate comfortably, securely, and seamlessly within Amazon Web Services (AWS) and Microsoft Azure, understanding the networking, compute, and identity fabrics of these public clouds.
• Proven Delivery Record: A demonstrable, proven track record of successfully designing, building, and delivering complex Windows solutions—not just maintaining or operating pre-existing environments.

What makes you stand out:

• Passion for the Industry: You live and breathe tech. You possess a nuanced, forward‑looking perspective on industry trends.
• Advanced Provisioning Expertise: Extensive, hands‑on experience utilizing automation tools and code to manage image pipelines across multi‑cloud environments.
• Cognitive Agility: An exceptional capacity for problem solving, allowing you to rapidly ingest data from disparate systems and formulate elegant technical solutions under extreme pressure.
• Advanced Automation & Coding: A proven ability to write clean, modular, and testable code. High‑level proficiency in PowerShell development alongside a strong command of Git version control methodologies.

Why join our team:

• We help you be your best through professional development opportunities, interesting work, and supportive leaders.
• We foster a vibrant and inclusive culture where you can work with talented colleagues to create new solutions and have an impact on colleagues, clients, and communities.
• Our scale enables us to provide a range of career opportunities, as well as benefits and rewards to enhance your well‑being.
