Mach Industries is seeking a New Grad Manufacturing Engineer to own the industrialization of our products for high-rate production. In this role, you will work closely with the Product Engineering, Build Engineering, and Manufacturing Operations teams to design, validate, and launch high-volume manufacturing systems using cutting-edge Manufacturing Engineering techniques. This role is focused on building at scale— delivering reliable hardware at speed.

At Mach Industries, we are building decentralized, autonomous systems to maintain an allied American edge in modern warfare. As a Manufacturing Engineer, you will play a pivotal role in developing flexible, adaptable manufacturing systems that enable rapid production at scale.

What you'd do

Take extreme ownership of production planning, from late-stage prototype builds through the mass-production ramp at Mach’s Forge Factories.
Design high-throughput manufacturing systems that achieve world-class first-pass yield at target cycle times.
Drive product design optimization using first-principles DFM/A, focusing on part-count and complexity reduction, tooling and equipment compatibility, and poka-yoke implementation.
Develop and execute fast-paced, robust manufacturing launch schedules.
Lead cross-functional make-or-buy studies with Supply Chain to secure rate-capable vendors and ensure on-time part availability.
Lead manufacturing virtual-build events covering fabrication feasibility and optimization, assembly sequencing, clearance analysis (hand, tool, and material), GD&T, DVA, part presentation and handling, tolerance stack-up risks, and other relevant topics.
Define the full manufacturing system through coherent MBoM, BoP, and BoE data structures captured in EasyPlan, DELMIA, Heliux, or an equivalent supporting tool.
Collaborate with Controls Engineering to conceptualize and deploy automation cells and conveyance systems. Project-manage vendors through factory acceptance testing (FAT) and on-site bring-up and site acceptance testing (SAT).
Own headcount and equipment capacity planning, OPEX and CAPEX estimates, PMTS cycle-time analysis (MODAPTS, MOST, and MTM), factory layouts in AutoCAD, and NIOSH-compliant ergonomics.
Support PFEP, including dunnage and material presentation; release controlled work instructions and quality gates in the MES; and provide daily production support during validation and factory production ramp-up.

What they want

1-3+ years of mechanical, manufacturing, build, or integration experience. Experience gained through project teams, research, internships, and professional roles qualifies.
Available to work extended hours and weekends as needed.
Competitive Salaries: We continuously research market rates to ensure our salaries are competitive with those in our industry and geographic location.
Performance-Based Incentives: Our bonus structure is tied to both individual and company performance, creating a win-win scenario that motivates our team members to excel.
Equity Participation: We offer stock options or equity to employees, ensuring that you share in the success and growth of the company.
Benefit Packages: Our benefits include healthcare, dental and vision plans, retirement savings, and paid time off, because we understand that your well-being extends beyond the office.
Professional Development: We allocate funds for continuing education, training, and career growth.
Transparency: We are committed to openness about our compensation tiers and how decisions are made, ensuring trust and mutual respect.
