At Senra Systems, we believe that the future of manufacturing lies not in automation, but in configuration.

We supercharge electrical wire harness manufacturing through software configuration, transforming skilled assembly tasks into high-throughput production lines. We enable customers to design what they want, when they want it and deliver harness builds at record-breaking speed.

This role is highly analytical and execution-focused, requiring strong organizational skills, business judgment, and the ability to interpret signals from across the company. Success is measured by forecast accuracy, schedule attainment, capacity utilization, revenue predictability, and the organization's ability to execute against plan.

• Ensure planning targets, milestones, and schedules are accurately maintained within AMP and associated planning systems.
• Identify critical path constraints across Production, Supply Chain, Inventory, Engineering, Quality, and Program Management.
• Recommend production pull-ins, push-outs, labor balancing, overtime utilization, and prioritization adjustments to optimize factory performance and revenue attainment.
• Partner with Production Control, Supply Chain, Engineering, Programs, and Production leadership to maintain schedule adherence and execution.
• Facilitate planning reviews and communicate schedule risks, mitigation plans, and forecast updates to leadership.
• Serve as the primary planning interface between Operations, Sales, Programs, Finance, Product, and Executive Leadership.
• Develop and maintain dashboards, reporting, and analytics that provide visibility into capacity, bookings, forecast accuracy, schedule attainment, and revenue projections.
• Leverage SQL, Python, Power BI, and other analytical tools to support decision-making and operational planning.
• Partner with Software and Product teams to improve planning systems, workflows, reporting, and automation capabilities.
• Continuously improve scheduling methodologies, planning processes, and forecasting accuracy.
