Manufacturing Engineer - Third Shift

Commonwealth Fusion Systems•Devens, MA

5d•$107,000 - $160,000•Onsite

About The Position

Commonwealth Fusion Systems is hiring a third-shift Manufacturing Engineer to support its superconducting magnet production line, where advanced magnet components are fabricated, inspected, assembled, and tested. The engineer provides on-shift support across production workstations to help keep operations safe and maintain high quality. The schedule is Monday through Friday, 10:00 pm to 6:30 am, with a 15% differential added to base pay. The role includes hands-on support for fabrication, welding, inspection, instrumentation, and cryogenic testing; troubleshooting process, equipment, and quality issues; and making real-time decisions, including when work should be held or stopped. The engineer verifies workstation setups against process plans, manages nonconformances and root-cause investigations, and maintains accurate work instructions and process plans in the manufacturing execution system. The role also coordinates with technical and quality teams, supports product configuration changes, trains production technicians, maintains shift handoffs, and drives improvements in throughput, turnaround time, and first-pass quality. Candidates should have a relevant bachelor’s degree or equivalent work experience and at least five years of manufacturing or production engineering experience. The position requires sound engineering judgment, communication and documentation skills, experience with nonconformance and corrective-action processes, MES or electronic work instructions, and hands-on troubleshooting of electromechanical equipment and instrumentation. The work is onsite and requires compliance with safety procedures and training. Physical requirements include occasionally lifting up to 50 pounds and standing, sitting, stooping, and typing for extended periods. Occasional travel or work on nights, weekends, or on-call may be required. The advertised salary range is $107,000–$160,000 per year. The position includes equity and benefits; actual salary depends on level, location, qualifications, and experience. Employment is subject to compliance with U.S. export control laws.

Requirements

Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Electrical Engineering, or a related field, or equivalent work experience.
At least 5 years of experience in manufacturing or production engineering, ideally supporting complex hardware, test stands, or quality-critical production.
Ability to read engineering drawings and technical documentation, including GD&T.
Sound judgment when making real-time third-shift engineering decisions within established guardrails, including knowing when to stop work and escalate.
Excellent written and verbal communication, including clear shift handoffs and documentation.
Experience with root-cause analysis and corrective-action processes such as RCCA or 8D, and with nonconformance management.
Experience with a manufacturing execution system (MES), electronic work instructions, or work orders.
Hands-on troubleshooting skills for electromechanical equipment, instrumentation, and data acquisition or controls systems.
Ability to work in a fast-paced, team-oriented environment, coordinate with fellow engineers on shift, and manage multiple priorities.
Ability to lift up to 50 pounds occasionally and to type, stand, stoop, and sit for extended periods.
Completion of required safety training, including lockout/tagout, cryogenic safety, and laser and radiation area awareness.
Dedication to safety in environments with potential hazards including heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics.
Willingness to occasionally travel or work required nights, weekends, or on-call.

Nice To Haves

Experience with superconducting magnets, HTS tape or cable, or cryogenic hardware.
Experience with laser or TIG welding and weld inspection methods such as VT, RT, or UT, or NDT certification.
Experience running or supporting a cryogenic test stand or high-current or high-voltage test equipment.
Experience with instrumentation such as voltage taps, cryogenic temperature sensors, or fiber-optic sensing, and with data acquisition and time-series tools.
Experience with Manufacturo, Odoo, Jira, or similar MES, quality, or ticketing systems.
Experience with NX or similar CAD software.
Proficiency in work-instruction writing, process mapping, and capacity modeling.
Familiarity with Python or similar tools for reviewing test data.
High self-motivation and ability to execute quickly with strong troubleshooting and problem-solving skills.

Responsibilities

Provide hands-on manufacturing engineering support for production operations, including fabrication, welding, inspection, instrumentation, and cryogenic testing.
Troubleshoot process, equipment, and quality issues and determine when to hold or stop work to protect people and products.
Verify and approve workstation setups against process plans, including hardware configuration, tooling, and torque sequences.
Disposition nonconformances and lead root-cause and corrective-action investigations.
Maintain accurate work instructions and process plans in the manufacturing execution system, including redlining steps, resolving blocked operations, and documenting lessons learned.
Coordinate with NDT, welders, technicians, controls, equipment, analysis, and quality teams to resolve issues safely and quickly.
Support product configuration changes, including updates to process plans, tooling, and work instructions.
Coordinate coverage and decisions with other third-shift engineers.
Maintain clear shift handoffs and documentation across all three shifts.
Train and support production technicians on work instructions, processes, equipment, and best practices.
Drive continuous improvement in throughput, turnaround time, and first-pass quality.
Ensure compliance with safety regulations, company policies, and industry standards.
