U.S. citizenship is required, as only U.S. citizens are eligible for the required security clearance. Qualifications We Prefer * Experience in signal Processing. * Experience with high-bandwidth mechatronics and dynamics. * Experience in research and development of precision pointing systems. * Work in a complex multi-task, schedule-driven environment. * Perform effectively with minimal day-to-day oversight * Advanced degree ## Description * This role is critical for the risk reduction and requirement-definition phase of the project's mechanisms. High-fidelity modeling of electromechanical actuators and sensors is required to validate designs against testbed data and to inform the specifications of future hardware iterations. * Distill complex models into low-fidelity versions for integration into larger system-level simulations. * Provide rapid-turnaround study results for sponsors and maintaining long-term, high-fidelity simulation infrastructure. * Responsibilities include, but are not limited to: * High-Fidelity Modeling: Maintain, modify, and develop high-fidelity behavioral simulations of electromechanical actuators and sensors. * Model Validation: Tune and validate simulations against actual testbed data to ensure physical accuracy. * Risk Reduction & Requirements: Utilize high-fidelity models to conduct risk reduction activities and establish technical requirements for future versions of mechanisms. * System Integration: Create and maintain low-fidelity "surrogate" models that approximate actuator behavior for use in larger, integrated system simulations. * Study Support: Execute rapid-turnaround tasks (2-3-week cycles) to support sponsor-driven studies, delivering results via plots and presentations. * Simulation Maintenance: Provide ongoing maintenance and updates to the project's primary simulation environment to ensure stability for other project stakeholders. * Vendor Technical Integration: Participate in vendor meetings and technical reviews to absorb critical design information, ensuring that behavioral models accurately reflect external hardware and software specifications. * Technical Versatility: Act as a flexible resource within a small team, providing overlap and support for other GNC functions as bandwidth requires. * Communication: Translate complex simulation data into clear, concise plots and PowerPoint presentations for internal and external stakeholders. ## Related Videos - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [RTX AI PC: Developing local and edge AI applications](https://www.wearedevelopers.com/videos/100078-rtx-ai-pc-developing-local-and-edge-ai-applications) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Introduction to Responsible AI: Balancing Value and Risk](https://www.wearedevelopers.com/videos/1972-introduction-to-responsible-ai-balancing-value-and-risk) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Building Trustworthy AI in Industry: Beyond Traditional Cybersecurity](https://www.wearedevelopers.com/videos/1948-building-trustworthy-ai-in-industry-beyond-traditional-cybersecurity) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Best US AI Conferences for CTOs in 2026: Build vs. Buy, Vendor Evaluation, and Peer Intelligence](https://www.wearedevelopers.com/magazine/736-best-us-ai-conferences-for-ctos-in-2026-build-vs-buy-vendor-evaluation-and-peer-intelligence) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers)
