Summary
Redwire Defense Technologies has an opportunity for a Guidance, Navigation, and Control (GNC) Sensors Engineer to join the Optics and Algorithms team at our Marlborough, MA facility. The GNC Sensors Engineer is a multifaceted role in the engineering team working to support design, analysis, and support of GNC subsystems on various space programs including star trackers, sun sensors, and terrain relative navigation. This role includes working at the interface of electronics, software, and optics to develop high performing algorithms that are used satellite and spacecraft navigation. In this role, you will directly interface with customers to present and defend our GNC solutions and their performance in meeting the mission requirements.
Responsibilities

• Perform analysis to support early design phase concept development including sensor selection, predicted performance assessment
• Work closely with senior subject-matter expert for sun sensors to gain deep technical knowledge and progressively take on ownership of the subsystem.
• Perform sensor modeling, characterization, and performance analysis, including noise modeling, error propagation, and environmental sensitivity.
• Support sensor selection and trade studies, evaluating performance, cost, SWaP, and integration constraints.
• Analyze flight or test data to evaluate system performance, identify anomalies, and recommend improvements.
• Work with cross-functional teams to integrate sensors and algorithms into broader GNC subsystems.
• Collaborate with hardware, systems, and software engineers to ensure end-to-end system reliability and robust sensor behavior in operational environments.
• Document designs, analyses, and test results in clear technical reports, presentations, and customer-facing materials.

Ideal Experience

• Bachelor's degree in physics, aerospace engineering, applied mathematics, or related field and 0-4 years of experience, or a Master's degree with 0-2 years of experience.
• Coursework, internships, or industry experience in Guidance, Navigation & Control (GNC), estimation, sensor fusion, or robotics perception
• Strong foundation in linear algebra, probability, estimation theory, and dynamic
• Hands-on experience with star trackers, sun sensors, IMUs, cameras, LiDAR, or other navigation-grade sensors
• Experience developing or analyzing Kalman filters, nonlinear estimators, or navigation algorithms
• Exposure to simulation environments (e.g., MATLAB/Simulink, Python-based simulation frameworks, C++ simulation tools)

Desired Skills

• Proficiency in Python, C++, or MATLAB for algorithm development and data analysis
• Ability to model sensor behavior, including noise characteristics, biases, and error propagation
• Understanding of coordinate frames, attitude representations, and reference frames used in aerospace and robotics
• Familiarity with electronic circuits (analog and digital)
• Strong debugging skills across software, algorithms, and sensor interfaces
• Clear technical communication skills for writing reports, documenting algorithms, and explaining results
• Curiosity, initiative, and a willingness to learn new sensing technologies and GNC techniques
