Senior Platform Windows Engineer

Firm Overview

Verition Fund Management LLC (“Verition”) is a multi-strategy, multi-manager hedge fund founded in 2008. Verition focuses on global investment strategies including Fixed Income & Macro, Event & Multi-Asset RV, Equity L/S & Capital Markets, and Quantitative Trading.

Department Overview

The Technology and Strats (Quant) teams build and operate the engineering platform behind the firm's investment activity and business functions globally. Working alongside the investment teams to create edge in research, portfolio construction, execution and risk management, and applying machine learning and AI across both the investment process and the firm's platform operations. Strategic Analytics ("Strats"), with its quantitative researchers and developers, partner directly with Portfolio Managers and the businesses on strategy-specific research, models, signals, backtesting and execution, while building the shared pricing, analytics and research infrastructure used across strategies. The core Technology teams own the firm's market, reference and alternative data platform; the infrastructure including cloud, compute, developer tooling, security and connectivity that everything at the firm runs on.

Role Overview

Windows Engineering owns the server-side Windows platform at Verition — the counterpart to our Linux platform, engineered to the same standard. This is not a desktop or end-user support role; it is core infrastructure work on the Windows Server fleet, Active Directory and identity, and the automation that keeps both reliable, secure, and fast across our data centers and cloud regions. As a Senior Platform Engineer, you'll own significant pieces of that surface hands-on, work closely with the Tech Lead for Linux Platform Engineering to shape one coherent OS-platform strategy across both kernels, and partner with engineering and quant research teams who depend on Windows for parts of their stack.

Responsibilities

• Engineer, automate, and operate the firm's Windows Server fleet across private data centers and cloud regions, holding it to the same reliability, performance, and security standards as our Linux platform.
• Own the design and operation of Active Directory and hybrid identity (Entra ID), including domain and forest architecture, Group Policy, trusts, and the integrations that connect Windows identity to the rest of the firm's systems.
• Build and maintain deployment, configuration, patching, and monitoring automation using PowerShell and modern configuration management, treating the Windows estate as code rather than as hand-managed servers.
• Define and enforce Windows security baselines and hardening standards, partnering with Security Engineering on patching cadence, privileged access, and the firm's broader identity and short-lived-credential strategy.
• Tune Windows Server for demanding, latency-sensitive workloads where the business requires it, working from the hardware and kernel up.
• Contribute to the OS-platform technical strategy set by the Tech Lead, Linux Platform Engineering, bringing deep Windows expertise so that decisions span both platforms coherently rather than treating Windows as an afterthought.
• Partner with Data Center & Fleet Infrastructure on provisioning and asset management, and with Developer Tools & Infrastructure on build and CI integration, so the Windows platform is well-integrated with the rest of the stack.
• Provide production support for the Windows surface, including participation in an on-call rotation, and drive continuous improvement of its reliability and observability.
• Mentor engineers across the team on Windows internals, identity, and automation, raising the bar for how the firm builds and operates Windows infrastructure.

Qualifications

• Bachelor's degree in computer science, a related technical field, or equivalent practical experience.
• 5 years of experience in systems or platform engineering, with a focus on Windows Server infrastructure.
• Advanced experience with Windows Server internals, performance tuning, and operating the fleet at scale.
• Deep, hands-on experience with Active Directory and hybrid identity (Entra ID), including domain/forest design, Group Policy, and trust relationships.
• Strong experience automating deployment, configuration, patching, and monitoring with PowerShell, including modern configuration-management approaches (e.g., DSC, Ansible, or equivalent).
• Experience defining and applying Windows security baselines and hardening standards (e.g., CIS Benchmarks, STIGs).
• Experience with distributed systems and cloud platforms.
• Excellent written and verbal communication skills.
• High level of intellectual curiosity, strong work ethic, and a keen attention to detail.
• Ability to work effectively in a team-oriented, fast-paced, and dynamic environment.
