Manufacturing Engineer - Third Shift

Commonwealth Fusion Systems•Devens, MA

3d•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 maintain safe, high-quality production and resolve operational issues. The schedule is Monday through Friday, 10:00 pm to 6:30 am, with a 15% differential added to base pay. The role involves hands-on production engineering, troubleshooting, workstation setup verification, nonconformance disposition, root-cause investigations, and maintaining accurate process plans and work instructions in the manufacturing execution system. The engineer coordinates across production, inspection, quality, equipment, and analysis teams; supports product configuration changes; trains technicians; documents shift handoffs; and drives improvements in throughput, turnaround time, and first-pass quality. The position requires compliance with safety regulations, company policies, and industry standards. This is a full-time, onsite role. The position pays $107,000–$160,000 per year, plus equity and benefits. The salary depends on level, location, qualifications, and experience.

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 on third shift, including making real-time engineering decisions within established guardrails and knowing when to stop work and escalate.
Excellent written and verbal communication skills, 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.
Ability to type, stand, stoop, and sit for extended periods.
Complete required safety training, including lockout/tagout, cryogenic safety, and laser and radiation area awareness.
Dedication to safety when working around hazards that may include 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 welding processes such as laser or TIG, 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, and 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 drive to execute quickly, with strong troubleshooting and problem-solving skills.

Responsibilities

Provide hands-on manufacturing engineering support for production operations across 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 product.
Verify and approve workstation setups against the process plan, 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 capturing lessons learned in controlled documents.
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.
