Systems Engineer Principal – Mission Performance

Job Description Quantify the Edge: Define Mission Success Join the Mission Engineering team at BAE Systems Space and Mission Systems, where we transform complex technical specifications into measurable mission victory. We are seeking a Mission Performance Engineer to serve as an analyst responsible for predicting, quantifying, and optimizing the effectiveness of advanced architectures across the space, air, and ground domains.

In this role, you will not just be analyzing a system; you will be defining the "performance story" of our most discriminating technologies. You will operate at the intersection of physics, mathematics, and strategy, using simulation and modeling to determine exactly how our systems will perform in contested environments.

As a key member of the Strategic Capabilities Unit (SCU), you will provide the data-driven confidence our customers need to make critical operational decisions. The Engineering, Science and Analysis (ESA) Strategic Capabilities Unit comprises the technical talent and organizational leadership that enables the successful delivery of high-impact discriminating technologies for our customers’ missions.

Our collaborative, cross-functional teams are committed to innovation, integrity, continual learning and strong execution.

What You’ll Do

• Performance Modeling & Quantification: Predictive Analysis: Utilize a custom-built tool-suite to characterize and quantify mission performance.
• You will move beyond basic requirements to determine the probability of mission success and identify performance gaps.

Tool Evolution

Lead the development of new algorithms and modeling tools to increase the fidelity of our performance predictions, ensuring our simulations reflect the complexities of real-world operational environments.

Performance Benchmarking

Establish KPIs and performance metrics that guide the design of components and systems, ensuring every technical decision is mapped back to a mission-level benefit.

Trade-Off Analysis & Optimization

Architectural Trade Studies: Conduct rigorous trade-off analyses to optimize system performance. You will determine the "sweet spot" between competing technical constraints to deliver the most effective solution.

Sensitivity Analysis

Identify the critical variables that most significantly impact mission success, allowing the design team to prioritize the most impactful technical improvements.

Requirement Derivation

Translate high-level mission goals into precise, quantifiable performance requirements for subsystems and components.
