Senior Manufacturing Engineer 

Parallel Systems is seeking a Senior/Principal Manufacturing Engineer to own the end-to-end transition from prototype to production, designing a greenfield production site from scratch to build our rail vehicle platform at scale. This role will own process flow design, station layout, and tooling. Ideal candidates have led at least one NPI program end-to-end and have hands-on experience standing up assembly lines for complex products. 

Responsibilities: 

• Lead the R&D-to-production transition, formalizing existing build processes and architecting a scalable, work-cell/station-based assembly flow — including designing a greenfield production site from scratch, with station layout, sequencing, and takt/cycle time allocation. 
• Lead New Product Introduction (NPI), transitioning vehicle designs from engineering prototypes into a validated, repeatable manufacturing process. 
• Specify, design, and source fixtures, jigs, and assembly tooling required at each station. 
• Partner with mechanical, electrical, and systems engineering to identify and resolve design-for-manufacturability (DFM) issues, including leading PFMEA for critical assembly processes. 
• Identify and help source capital equipment needed to outfit the line, working closely with facilities and supply chain. 
• Build manufacturing process documentation, including work instructions, routers, and station standard work. 
• Partner with quality engineering to define production data to capture, set process control limits, and enable data capture, validation, and visualization (e.g., SPC dashboards) alongside inspection points and first-article process. 
• Act as the go-to technical authority for manufacturing process and assembly line design, providing guidance to other engineers and influencing Parallel Systems' broader approach to production. 

What Success Looks Like:

• With in 30 days: You will have deep understanding of the Mk3 vehicle design, its systems, and installation dependencies.  
• With in 60 days: You will have developed preliminary concepts for manufacturing facility layouts, estimating space, equipment, and labor requirements along with vehicle throughput. They will present trades to leadership and play a crucial role in deciding near-term company manufacturing strategy. 
• With in 90 days: You will have started a detailed shop layout and process design consistent with the selected manufacturing plan. They will participate in ongoing Mk3 vehicle builds to better understand the design and existing process, and work with the design team to capture additional nuances. They will support procurement of critical long-lead equipment and fixtures. 

Requirements: 

• 5+ years of experience in manufacturing engineering. 
• Demonstrated ownership of at least one NPI program from prototype through production launch. 
• Direct experience designing and standing up an assembly line or work-cell operation. 
• Experience specifying and sourcing fixtures, tooling, and capital equipment, including managing vendor lead times. 
• Strong in DFM principles and a track record of influencing product design from a manufacturing perspective. 

Preferred Qualifications: 

• Experience in rail, transit, aerospace, or heavy equipment manufacturing. 
• Experience with large/heavy vehicle subassemblies, including crane-assisted handling and structural lifting. 
• Familiarity with PFMEA methodology and hardware development gate processes (CDR or similar). 
• Startup or small-team experience, with the ability to build manufacturing process from nothing.
