Job Title: Senior Windows Systems Engineer

Job Description

We are seeking a highly skilled Senior Windows Systems Engineer to design, build, and maintain the core Windows software that powers our mammography display stations. This role focuses on native Windows development at the system level, involving Windows desktop applications and background services that operate close to the operating system and hardware. This is a critical position in a regulated medical environment, emphasizing Windows OS behavior, long-running services, multithreading, memory management, inter-process communication, and system reliability.

Responsibilities

• Develop and maintain native Windows desktop applications and Windows services written in C++.
• Build background services that start with the system and manage critical workstation behavior.
• Work directly with Windows APIs to handle processes, threads, synchronization, file system access, and OS lifecycle events.
• Design and maintain multi-process architectures, including secure inter-process communication (IPC).
• Ensure software behaves correctly across Windows state changes such as login/logout, lock/unlock, restarts, and remote sessions.
• Debug and improve stability, performance, and reliability, addressing issues like crashes, hangs, and memory problems.
• Operate in a driver- and hardware-adjacent environment from user-mode code, without writing drivers.
• Collaborate with adjacent teams working in C# and, where applicable, .NET-based components.

Essential Skills

• 3+ years of professional experience developing native Windows software in C++.
• Experience building and owning Windows desktop applications and/or Windows services in production.
• Direct experience working with Windows APIs and OS-level behavior, beyond high-level frameworks.
• Hands-on experience with multithreaded C++ applications and concurrency challenges.
• Strong understanding of C++ memory management, including ownership, lifetimes, RAII, and smart pointers.
• Experience debugging crashes, memory leaks, hangs, or performance issues in production systems.
• Experience working with multi-process systems and at least one Windows IPC mechanism.
• Comfort operating in system-level or OS-adjacent Windows applications that must run reliably over long periods.
• Understanding of Windows execution contexts, including user vs. service operation and permission constraints.

Additional Skills & Qualifications

• Experience with Windows Services running under service accounts.
• Familiarity with hardware- or driver-adjacent Windows applications (user-mode interaction).
• Exposure to environments with mixed C++ and .NET components.
• Experience in medical systems, imaging workstations, or other regulated/mission-critical software.
• Experience with Windows diagnostics tools such as logging, crash dumps, and system diagnostics.
• Bachelor's degree in Computer Science, Mathematics, or a related field.
• Experience with Windows 10/11.
