A Day in the Life

Cranial & Spinal Technologies develops integrated technologies and procedural solutions that support the diagnosis and treatment of neurological and spinal conditions. Within Research and Development, this team verifies complex systems that combine software, hardware, connected technologies, and capital equipment used in the operating room. This position is based onsite in Lafayette, Colorado. The role supports a primarily U.S.-based team and requires approximately 25% travel, primarily domestic with potential international travel.

As a Senior Test Engineer, you will develop and execute verification and validation strategies for complex medical products integrating software, hardware, and connected systems. You will provide technical leadership across the product-development lifecycle, identify product and patient-safety risks, and translate test findings into practical solutions, mitigation plans, and optimized testing approaches. You will also apply automation and AI-enabled tools to improve test efficiency, traceability, and coverage within Quality System controls.

Primary Responsibilities

• Develop verification and validation strategies, test methods, plans, protocols, and reports for new and modified integrated products.
• Lead testing of software running on complex capital equipment, including connected hardware, system interfaces, fixtures, phantoms, and supporting tools.
• Design, develop, integrate, and validate test software and automated testing solutions that improve coverage, repeatability, and efficiency.
• Evaluate and implement AI-assisted workflows for test development, requirements and code-change analysis, defect investigation, documentation, and reporting.
• Analyze test results, identify product issues, and recommend technical resolutions, risk mitigations, or optimized testing strategies.
• Provide technical leadership and mentoring to test engineers while collaborating with systems, software, experience engineering, quality, regulatory, and R&D leadership.
• Coordinate testing at internal and external facilities and ensure test equipment, tracking systems, and data-recording systems are maintained and appropriately calibrated.
• Participate in requirements, design, usability, risk, and defect reviews while ensuring activities comply with applicable Quality System requirements.

Required Qualifications

• Bachelor's degree in Engineering or Computer Science with 4+ years of engineering experience OR master's degree in Engineering or Computer Science with 2+ years of engineering experience OR PhD in Engineering or Computer Science.
• Experience performing verification or validation testing in a regulated product-development environment.
• Experience testing complex, end-to-end systems integrating software and hardware.
• Experience developing test strategies, test methods, protocols, reports, or automated test solutions.
• Ability to travel approximately 25%, primarily domestically with potential international travel.

Preferred Qualifications

• Experience with medical devices, capital equipment, robotics, operating-room technology, or other safety-critical systems.
• Knowledge of applicable AAMI, ISO, FDA, or European Norm standards.
• Experience developing or maintaining test software and automated system-level testing solutions.
• Experience applying AI tools to test strategy, test-script development, requirements or code-change analysis, debugging, defect investigation, or technical documentation.
• Experience making risk-based testing decisions and adjusting test scope or methods when time, staffing, or resources are constrained.
