Senior Windows Systems Engineer: C++, IPC & Multithreading

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, including Windows desktop applications and background services that run close to the operating system and hardware. This position requires a deep understanding of Windows OS behavior, long-running services, multithreading, memory management, inter-process communication, and system reliability in a regulated medical environment. Responsibilities Develop and maintain native Windows desktop applications and Windows services. Build background services that start with the system to 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 crashes, hangs, and memory issues. 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 (logging, crash dumps, system analysis). Bachelor's degree in Computer Science, Mathematics, or a related field. Work Environment The work environment is characterized by a small, collaborative team of 8‑10 individuals located in Portland. The position involves working closely with Windows technologies and requires a deep understanding of system‑level development. Training will be provided for 6 months under a retiring Senior member, offering a wealth of development knowledge and the opportunity to take over product ownership. The company culture includes employee appreciation initiatives, fostering a supportive and engaging workplace. Job Type & Location This is a Contract to Hire position based out of Beaverton, OR.
