Job Description

Summary:

Summary:

The Motion Control Engineer is responsible for the research, planning, design, and development of the core software elements that control the critical motion mechanisms contributing to the function and performance Accuray's radiation therapy products. This specialized role will also assist with defining the high-level architecture and detailed hardware implementation of these motion devices, leveraging a cross-functional skillset across multiple applicable engineering disciplines (Software, Mechanical, Electrical, Systems, etc) to help solve complex engineering problems.

Essential Duties and Responsibilities:

• PRODUCT DEVELOPMENT

• Software and hardware development of Accuray's control systems, including robotic manipulators, precision positioning systems, thermal and pneumatic control systems. Detailed analysis reports (design reviews, control system models, DFMEA, etc), debugging, reliability cycling, system integration and formal testing are key components of the development activities.

• Researches, analyzes, plans and implements the control system design in accordance with product requirements as established from various sources including marketing, manufacturing, reliably, and customer specification documents. Drives distillation of system level requirements into sub-system and component level requirements.

• Develops and executes comprehensive test plans, including manual and automated tests, to rigorously verify developed hardware and software against defined requirements and specifications.

• Hands-on, data driven problem solving - commonly working directly with motion hardware to move development efforts forward. Assists with hardware prototype builds and troubleshooting as needed.

• Documents, implements and tests applicable design requirements for production. This includes supporting transfer of relevant design output documents, recommended assembly and test instructions, and service troubleshooting support.

• Collaborates closely and frequently with Embedded Software Engineering, Mechanical Engineering, and Electrical Engineering throughout the product development lifecycle.

• Provides subject matter expert input and guidance for field service escalations into engineering.

• Supports the Mechanical Systems Manager in establishing or updating project and departmental deliverables.

• LEADERSHIP

• Provides technical leadership, leads by example, and mentors other employees within the Mechanical Systems group and Product Development.

• May serve as the lead Engineer on projects, and coordinate the work of other engineers, technicians, or contributors.

• Assures that quality processes are followed on projects and within the Mechanical Systems group.

• Contributes to the development or improvement of processes.

• SAFETY AND QUALITY

• Ensure safety and quality considerations and requirements are proactively addressed and implemented in product design.

• Address and manage in a timely fashion safety and quality issues raised by customers or staff.

• Supports Accuray's Quality System and Safety and Health Program by following procedures and mentoring others.

Qualifications:

a. Required

• Bachelor's degree in computer science, Software Engineering, Data Science, Engineering Physics, Mechanical Engineering, Mechatronics, or a closely related technical field.
• At least 4 years of software development experience, working directly with electro-mechanical control systems.
• Familiarity with Mechanical, Electrical, and Software Engineering design principles.
• Proficiency in object-oriented programming such as C++, Python, and MATLAB.
• Track record of on time, high quality production launches of released software and associated components.
• Excellent verbal and written communication skills. Able to effectively present technical concepts to individuals that are not subject matter experts and assist as needed.

b. Preferred or Desired

• Advanced degree in Computer Science, Software Engineering, Data Science, Engineering Physics, Mechanical Engineering, Mechatronics, or a closely related technical field.
• At least 8 years of design and development experience in a highly regulated, safety-critical industry.
• Demonstrated ability to test and verify developed hardware and software against requirements.
• Ability to develop system-level requirements for motion control systems, and effectively integrate both individual components into a system and sub-systems into a larger system.
• Extensive experience working with automated systems, their components (motor controllers, drive electronics, etc.) and writing any associated low-level firmware and mid-level software interfaces/device drivers, and robot controls middleware.
• Experience programming digital motion controllers, including configuration and utilization of digital I/O for motion control applications.
• Self-starter who works independently to solve problems, manage workload and resolve roadblocks - collaborating with peers and management as appropriate.
• Experience in strategic infrastructure planning, developing roadmaps to achieve long-term objectives, and successfully implementing those plans.
• Demonstrated experience working in Linux-based environments.
• Exposure to 3D CAD modeling software (SolidWorks preferred) and virtualization tools for robotics applications.
• Exposure to Real-Time Operating Systems (RTOS) and parallel computing concepts.
• Proficiency with linear algebra and rigid transformation and/or Robotics experience with serial link manipulators.
• Proficiency in working with databases, including querying, data manipulation, and schema design.
• Strong foundational knowledge in control theory combined with hands-on experience developing data-driven control strategies.
• Comfortable and proficient in utilizing AI tools to enhance productivity and problem solving.
• Understanding of fundamental learning algorithm concepts (ML/RL) and their potential utility in advancing robotic capabilities.
• Formal product reliability qualification and testing background.
