Role Summary:
The Senior Manufacturing Engineer plays a critical role in bridging the gap between design engineering and production operations. This position is responsible for ensuring that new product designs are effectively transitioned into the manufacturing environment with a focus on manufacturability, cost efficiency, quality, and scalability. The Senior Manufacturing Engineer will evaluate product designs, optimize assembly processes, develop detailed work instructions, and provide hands-on support and training to production teams. This role requires strong technical expertise, excellent communication skills, and a continuous improvement mindset.

This is a highly experienced engineering role embedded within the Operations team, with deep expertise in assembly processes, process optimization, and New-Product Introduction (NPI).

The Senior Manufacturing Engineer brings a strong understanding of lean methods, CAD/ERP workflows, and production system requirements, and leads scoped NPI projects and subsystem readiness across the product lifecycle. The role supports engineering excellence through hands-on problem-solving, cross-functional collaboration, and peer mentorship, while delivering high quality documentation, tooling plans, and on-the-floor support to ensure build success.

Essential Responsibilities:

• New Product Introduction (NPI): Act as the liaison between engineering and production to integrate new designs into manufacturing. Support early-stage builds by physically assembling parts to validate design intent and process feasibility. In addition, supporting the NPI through to the flight testing group to validate the NPI project.
• Hands-On Assembly & Design Feedback: Build prototypes and initial production units to learn optimal assembly sequences, tooling, jigs, and fixture needs. Provide clear, actionable feedback to design engineers to improve manufacturability and ease of assembly.
• Work Instructions and Documentation: Create and maintain detailed, step-by-step assembly instructions and related documentation using tools such as Microsoft Word, PowerPoint, and Excel. Experience working directly with technical writers to transition work instructions into forms that ensure process traceability by recording work performed in travelers, logs, or digital systems a plus. May mentor others in best practices for documentation quality and version control.
• Process Development and Optimization: Design and refine manufacturing processes and assembly flows. Implement lean principles to reduce waste and improve efficiency. Determine tooling and fixture requirements, and work with internal or external partners to develop or procure them. Lead scoped process improvement projects across subsystems or platforms.
• Work Instructions and Documentation: Create and maintain detailed, step-by-step assembly instructions and related documentation using tools such as Microsoft Word, PowerPoint, and Excel. Experience working directly with technical writers to transition initial work instructions into XML-based documentation system to ensure traceability; experience with travelers, logs, or digital systems a plus. May mentor production staff in best practices for documentation quality and version control.
• Training and Support: Train assembly leads and technicians on new products, processes, and equipment. Troubleshoot production issues and act as a hands-on technical resource on the shop floor. Good interpersonal skills are highly desired in this role to act as a peer mentor to both technicians and junior engineers.
• Quality and Continuous Improvement: Collaborate with cross-functional teams to resolve quality issues and nonconformances. Drive continuous improvement initiatives using methodologies such as Six Sigma, 5S, and PFMEA. Champion structured root-cause analysis and corrective actions.
• Ensure Compliance and Safety: Ensure that all manufacturing activities comply with safety standards, company policies, and regulatory requirements. Support the development of safe work procedures and tooling evaluations.
• Tooling and Jig design involving CAD Designs (Solidworks) and development to support manufacturing as needed
• Other duties as assigned.

Qualifications & Experience:

Required:

• Education: Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Industrial Engineering, or a related field. (or a demonstrated equivalence)
• Experience: 7+ years of experience in a manufacturing engineering role, preferably in a high mix, low-volume, or complex assembly environment. Experience specific to UAS is a big plus.
• Technical Skills: Strong knowledge of DFM principles, lean manufacturing, and process optimization. Excellent problem-solving skills and ability to work cross-functionally. Proficient in CAD software (e.g., SolidWorks, AutoCAD) and ERP/MRP systems.
