Senior Industrial Engineer, Simulation

Anduril's Manufacturing Team is seeking a Senior Industrial Engineer to own and scale our manufacturing simulation capability. The Manufacturing Team is responsible for rapidly iterating and building cutting-edge defense hardware — including static equipment, moving ground equipment, sensors, undersea, and flight vehicles — and scaling these products across our production footprint, including our new 5M sq ft manufacturing facility, Arsenal-1.

Within Manufacturing, Industrial Engineering delivers simulation as an internal service: validated digital twins of our production systems that model capacity, quantify constraints, stress-test production plans, and evaluate design and capital-investment trade-offs *before* physical implementation. Done right, simulation de-risks capital expenditures, accelerates new-product-introduction (NPI) ramps, and arms leadership with validated production models and quantified risk — turning manufacturing predictability into a strategic advantage. This role sets the standard for how that capability is architected, validated, and consumed across the company, in close collaboration with Supply Chain, Engineering, Quality, Program Management, and Business Operations.

ABOUT THE ROLE

This is not a "build a model and move on" role. We are looking for a senior engineer who can demonstrate holistic ownership of Anduril's factory simulation capability as a durable, decision-grade asset — one that lives for years, absorbs new data as our production system evolves, and is trusted by leadership to make real capital, capacity, staffing, and ramp decisions. The right person thrives in a fast-paced, resource-limited environment, is flexible to change and ambiguity, and can act as the connective tissue among operational stakeholders to bring a production system forward.

The mandate is bigger than any single study. Our manufacturing environment is multi-variant, relatively low-volume, and runs on shared resources under fluctuating demand, evolving designs, and constrained supply chains — conditions where traditional capacity math breaks, because static spreadsheets can't capture resource contention, queue dynamics, or cascade failures. You will decide how simulation is architected, versioned, validated, and consumed so that "can we hit this rate?", "where's the bottleneck?", and "what happens if this line goes down?" become queries against a maintained, centralized model — not one-off spreadsheets that go stale the week they're delivered — and are digestible enough that a program or operations lead can pull a defensible production plan without a background in operations research.

• Own Anduril's discrete event simulation and operations-research capability for manufacturing as a long-lived, foundational asset — architecting it for maintainability, extensibility, and a high useful lifetime rather than single-use analysis.
• Capture current and planned processes — physical constraints, business rules, and detailed decision logic — into validated digital twins that serve as a living, "current-status" reference model for determining future factory and supply-chain performance across transformation projects and investment decisions.
• Design the data pipeline that keeps models current: define how live production data (cycle times, yields, routings, downtime, WIP, labor) flows in so models continuously reflect reality and can generate updated, feasible production plans and schedules as conditions change.
• Select and apply the right method for the question — baseline capacity analysis, discrete event simulation, Monte Carlo, and statistical/optimization models (regression, linear/integer programming, queuing) — and justify why a given approach fits the decision at hand.
• Lead the highest-stakes simulation studies: capacity modeling, NPI ramp simulation, capital-investment analysis with quantified ROI, line balancing and flow optimization, design-change impact analysis, and production risk/scenario planning (demand variability, supplier disruption, equipment failure via MTBF/MTTR).
• Own the desig
