Lead Systems Engineer

Do you want to be part of a business that genuinely values **entrepreneurialism**, **innovation** and **individual accountability?** We **focus on our customers** and are proud of the difference our technology makes. We partner with some of the biggest manufacturing companies in the world and our technical innovations are used to enhance well-known brands across multiple industries. **Title** Lead Systems Engineer **Department** Engineering - Development **Location** Niwot/Hybrid **Reports** **To** Director of Engineering **About Us** Established in 1972, Particle Measuring Systems is a **global leader for micro-contamination monitoring** equipment improving the performance of clean manufactures in the **semiconductor** and **pharmaceutical** industries. We’re a growing technology company in Niwot, Colorado, the heart of the Rocky Mountains. We offer an exceptional and rewarding work environment in a great place to live. Our employees enjoy challenging projects in the development and manufacture of light scattering particle counters and diverse technologies and applications. **Your Impact** We are looking for a Lead Systems Engineer who will contribute to the success of the Engineering Team, applying their expertise in system architecture and integration to support the achievement of team and company goals and deliver innovative, reliable solutions. In this role, the successful candidate will collaborate effectively with colleagues and cross-functional teams, demonstrate strong problem-solving and decision-making skills, and maintain a commitment to professional excellence, quality and continuous improvement. **The Role** We are seeking a Lead Systems Engineer to serve as the system-level technical authority for complex, multi-disciplinary instrumentation products. This role will drive system architecture, integration, and verification across the full product lifecycle. This position is foundational in strengthening and scaling systems engineering within the organization. The successful candidate will establish best practices, drive cross-functional alignment, and help build systems engineering capability, with the opportunity to grow into formal team leadership as the function expands. Because the core performance and testability of our optical particle counters are determined at the interface of optics, photonics, and the detection signal chain, the role carries explicit design authority over system architecture, requirements, and verification adequacy, and is empowered to make and arbitrate cross-functional technical trade-off decisions across the optical, electrical, firmware, software, and mechanical disciplines. **Job Responsibilities** - Own system architecture development, including decomposition, interface definition, and performance budgeting across subsystems. - Serve as the system-level technical authority, driving key architecture decisions and trade-offs. - Hold clear decision rights at the system level: decide system architecture, interface definitions, and verification adequacy; recommend trade-offs that affect cost, schedule, and scope to program and portfolio leadership; and resolve cross-discipline technical disputes through the engineering leadership chain. - Lead requirements engineering and maintain full traceability from customer needs through verification (JAMA or equivalent). - Drive system-level integration strategy and execution, ensuring performance, reliability, and manufacturability. - Identify and mitigate cross-functional risks and integration gaps early in development. - Ensure alignment of subsystem design with overall system performance and interface definitions. - Define and execute system-level verification and validation strategies, including integration planning and performance characterization. - Lead root cause analysis of complex system issues using analytical modeling and experimental methods. - Ensure systems meet requirements across all operating conditions. - Partner closely with…
