4.2. Senior Manufacturing Engineer

Phoenix Tailings•Exeter, NH

44d•Onsite

About The Position

Phoenix Tailings is looking for a Senior Manufacturing Engineer to take technical ownership of complex manufacturing processes, equipment, and scale-up efforts at our Exeter facility. This role will be central to turning developing process technologies into robust, high-performing manufacturing systems capable of supporting commercial-scale critical metals production. You will be expected to solve difficult production problems, define manufacturing standards, drive equipment and process improvements, and make engineering decisions that directly influence capacity, reliability, cost, quality, and safety. We are looking for an engineer who thrives in a hands-on environment, can operate effectively with incomplete information, and is motivated by the opportunity to build manufacturing infrastructure that does not yet exist.

Requirements

Bachelor's or Master’s degree in Mechanical Engineering, Manufacturing Engineering, Industrial Engineering, Chemical Engineering, Materials Engineering, or a related technical discipline.
6+ years of experience in manufacturing engineering, process engineering, production engineering, equipment engineering, or a related industrial environment.
Demonstrated experience owning and improving complex manufacturing processes or production equipment in a hands-on operating environment.
Strong experience with root-cause analysis, process optimization, equipment troubleshooting, and implementation of corrective and preventive engineering solutions.
Experience specifying, commissioning, qualifying, and ramping manufacturing equipment or production systems from installation through stable operation.
Demonstrated ability to use production data, process capability, engineering experimentation, and structured problem-solving to drive measurable manufacturing improvements.
Strong working knowledge of engineering drawings, GD&T, CAD, equipment specifications, manufacturing documentation, and design-for-manufacturing principles.
Proven ability to independently drive complex technical work from problem definition through implementation in a fast-moving manufacturing environment.
Able to lift up to 50 lbs
Able to wear a respirator for extended periods of time

Responsibilities

Own the technical performance and continuous improvement of critical manufacturing processes, driving measurable improvements in throughput, yield, reliability, quality, safety, and cost.
Lead the design, development, and implementation of tooling, fixtures, equipment modifications, and manufacturing systems required to scale Phoenix Tailings' production capabilities.
Diagnose complex equipment and process failures, lead root-cause investigations, and implement permanent corrective actions that improve long-term production stability.
Define manufacturing process requirements, operating windows, control strategies, and engineering standards needed to transition technologies from development into reliable production.
Lead the specification, design review, installation, commissioning, qualification, and ramp-up of new production equipment and manufacturing systems.
Develop and execute engineering trials, process validation plans, and scale-up studies that reduce technical risk and establish repeatable production methods.
Use production data, equipment performance, and process capability analysis to identify capacity constraints and prioritize high-impact manufacturing improvements.
Drive design-for-manufacturing decisions for new equipment, components, and process technologies to improve scalability, maintainability, and production readiness.
Serve as a technical resource on manufacturing engineering decisions, providing guidance on equipment design, process development, troubleshooting, and manufacturing best practices.
