About the Role
As a Material Flow Engineer on the Manufacturing Engineering team, you will design the factory layouts, work methods, and capacity models that enable Zipline to scale production reliably.
You will connect demand, labor, equipment, space, and capital investment through time studies, standard work, line balancing, and production-system design. Working directly on the factory floor, you will turn observations and production data into practical changes to station loading, operator movement, layouts, and manufacturing capacity.
Your work will help the team determine how much we can build, where the constraints are, and which investments in people, equipment, automation, or space will support the next stage of production.
This role is based in South San Francisco. This opening sits within our manufacturing engineering team; the exact focus will reflect your strengths and the team’s needs.
What You’ll Do
Improve factory layouts, workstations, operator movement, and material presentation.
Define WIP, buffer, queue, and rework strategies that protect output while reducing inventory and lead time.
Partner with Manufacturing, Production, Supply Chain, and Material Planning on line architecture, lineside availability, and replenishment.
Lead time studies, define standard work and labor models, and balance station loading against takt time.
Build capacity and capital-investment scenarios for labor, equipment, tooling, shifts, floor space, and future demand.
Identify current and future bottlenecks and implement improvements in throughput, utilization, cycle time, labor efficiency, and cost.
Own factory performance and production-system design, connecting individual processes into an efficient end-to-end system.
Develop factory KPIs, decision tools, make-versus-buy analyses, and investment cases; carry improvements through implementation.
What You’ll Bring
A bachelor’s degree in Industrial Engineering, Manufacturing Engineering, Mechanical Engineering, Operations Research, Systems Engineering, or a related technical field.
3+ years in industrial engineering, manufacturing engineering, operations engineering, production systems, or a comparable environment.
Experience with time studies, labor and capacity models, line balancing, takt time, standard work, factory layouts, and material flow.
A record of identifying manufacturing constraints and improving throughput, productivity, utilization, lead time, or cost.
Strong spreadsheet and analytical skills, including work with ERP, MES, labor-tracking, and production data.
Ability to build operational and financial models for capital investment, automation, make-versus-buy, and factory scaling.
A hands-on approach, clear communication, and ownership of improvements from ambiguous problemx through implementation
Nice to Have
5–7 years of relevant experience.
Experience scaling complex electromechanical products, expanding factories, or launching new production lines.
Familiarity with simulation, optimization, SQL, Python, BI tools, manufacturing dashboards, or ERP/MES platforms.
Experience with Lean manufacturing, Theory of Constraints, PFMEA, value-stream mapping, or automation business cases.
