Senior Test Engineer

Ralliant•Boxborough, MA

About The Position

We are seeking a Senior Test Engineer who will own and drive the test strategy and architecture for complex precision motion and electromechanical systems across the entire product lifecycle. This role goes beyond execution and requires deep technical leadership, system-level thinking, and cross-functional influence. You will define how products are validated, ensure scalability of test solutions, and drive design improvements through data-driven insights. As a senior member of the engineering team, you will act as the subject matter expert in test engineering, influencing product design, mentoring team members, and advancing test methodologies to support innovation, quality, and operational excellence.

Requirements

Bachelor’s or master’s degree in electrical engineering, mechanical Engineering, physics, or related field
5+ years of experience in test engineering or system validation for complex electromechanical systems
Proven track record of: Owning and delivering test strategies for new product development (NPI)
Proven track record of: Developing automated test systems (software + hardware)
Proven track record of: Leading cross-functional technical initiatives

Nice To Haves

Theoretical and practical understanding of basic analog and digital servo control theory
Advanced troubleshooting across electrical, mechanical, and system-level domains
Experience with Motion Controls, Drives, Motors, Encoders and Power Supplies
Measurement and testing of precision positioning systems
Working knowledge in programming with languages such as C, C++ and/or C#
Strong expertise in test system architecture and automation
Proficiency with LabVIEW or equivalent test automation tools
Programming experience in C, C++, C#, Python, or similar
Hands-on experience with measurement tools (oscilloscopes, DAQs, sensors, metrology systems)

Responsibilities

Define, own, and drive the end-to-end test strategy across product development, validation, and production phases.
Design and develop scalable automated test solutions, including hardware fixtures and software frameworks, for both development and manufacturing environments.
Establish and maintain system-level test architectures, protocols, and validation methodologies for complex motion control systems.
Analyze, interpret, and communicate test results, providing data-driven insights to influence product design and technical decisions.
Lead cross-functional failure analysis and root cause investigations, driving resolution across electrical, mechanical, and software domains.
Collaborate with design engineering to implement design-for-testability and improve product robustness and test efficiency.
Identify technical risks early and develop mitigation strategies through structured testing and rapid prototyping.
Drive continuous improvement of test processes, focusing on test coverage, cycle time, cost, and product quality.
Develop and implement advanced test data acquisition, analytics, and digitalization approaches to enhance decision-making.
Provide technical leadership and mentorship to test engineers and technicians, supporting skill development and best practices.
Act as a subject matter expert for test engineering, influencing cross-functional stakeholders including R&D, Quality, Manufacturing, and Program Management.
Support production test systems and operations to ensure quality, throughput, and reliability targets are consistently met.
