Engineer II / Senior Mechanical Engineer, Sustaining Engineering

Your Impact at LILA Lila is seeking a Mechanical Engineer II/Senior Engineer on our Sustaining Engineering team to improve the reliability, uptime, and lifecycle performance of deployed bench-scale robotics and mechanical systems. This role focuses on sustaining and improving fielded robotic workcells rather than greenfield design, with ownership across troubleshooting, root cause analysis, preventive maintenance, design fixes, and targeted reliability improvements. You will support mechanical systems used across life science and physical science automation, partnering closely with hardware, controls, software, lab operations, and scientific teams. The role requires strong mechanical engineering fundamentals, practical problem-solving under operational pressure, and the ability to translate recurring field issues into durable design and process improvements. This role owns rapid issue resolution and targeted design improvements that keep deployed systems reliable as Lila scales. What You'll Be Building Maintain, troubleshoot, and improve deployed bench-scale robotics and mechanical systems used in scientific automation workflows. Diagnose failures across pneumatic, electromechanical, optical, and mechanical subsystems, then implement durable corrective actions. Use SolidWorks CAD and analysis to design replacement parts, retrofits, fixtures, and reliability improvements. Create and validate prototypes, spares, and design fixes using 3D printing, laser cutting, and other rapid fabrication methods. Perform structured root cause analysis using methods such as 5 Whys and fishbone diagrams. Manage engineering changes through ECO/ECM, PDM/PLM, and requirements management systems. Plan preventive maintenance, manage component obsolescence, and recommend upgrades as systems mature. Track reliability metrics such as uptime, MTBF, MTTR, and recurring fault rates to guide improvement priorities. Maintain design documentation, runbooks, technical specifications, and lessons lea
