At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 350 employees, we operate with startup agility and ambition.\nOur vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security.\nThe Role\nMach Industries is seeking a GNC Engineer, Navigation to help develop, implement, and test navigation systems for autonomous aircraft and related defense platforms. You will contribute across state estimation, inertial navigation, sensor modeling, simulation, embedded implementation, hardware integration, and flight-test analysis.\nThis is a hands-on engineering role for someone building depth in navigation and estimation while delivering real vehicle capability. You will work with experienced GNC engineers to turn requirements into algorithms and analyses, characterize sensor behavior, investigate system performance, and build evidence that navigation functions operate reliably.\nThe ideal candidate has strong engineering fundamentals, enjoys solving problems with models and data, and is motivated to learn quickly. You approach work carefully, communicate assumptions and results clearly, seek feedback early, and take increasing ownership as your technical judgment develops.\nKey Responsibilities\nNavigation Algorithm Development\nSupport the design, implementation, tuning, and verification of navigation functions such as strapdown inertial navigation, state estimation, Kalman filtering, sensor fusion, alignment, calibration, measurement handling, and fault detection.\nTranslate defined vehicle objectives into analysis tasks, navigation performance metrics, simulation cases, and verification evidence with guidance from senior engineers.\nDevelop and evaluate propagation and measurement models, coordinate-frame transformations, initialization logic, and nominal or degraded sensor behavior.\nAnalyze the effects of sensor noise, bias, drift, scale factors, misalignment, lever arms, timing errors, latency, environmental conditions, and vehicle dynamics.\nEvaluate estimator convergence, consistency, numerical behavior, residuals, and recovery across representative trajectories and sensor conditions.\nDocument methods, assumptions, results, limitations, and recommendations in a clear and reproducible form.\nSensor Modeling and Characterization\nSupport the evaluation and integration of IMUs, GNSS receivers, magnetometers, barometers, air-data sensors, cameras, radar, and other aiding sources as applicable.\nAnalyze recorded sensor data to characterize noise, bias, repeatability, drift, latency, synchronization, thermal behavior, and other relevant error sources.\nDevelop sensor error models for simulation using test data and appropriate statistical methods.\nSupport stationary, dynamic, thermal, vibration, and environmental tests, including test setup, data collection, analysis, and reporting.\nContribute to sensor trade studies and calibration or acceptance-test activities using defined requirements and evaluation criteria.\nWork with Avionics, Electrical Engineering, Mechanical Engineering, Embedded Software, and Test to resolve installation, timing, data-quality, and interface issues.\nSimulation, Software, and Verification\nDevelop and maintain navigation simulations, sensor models, trajectory cases, fault scenarios, and truth-data interfaces.\nBuild and run Monte Carlo analyses, parameter sweeps, covariance analyses, sensitivity studies, and requirements-based tests.\nImplement, test, and review navigation algorithms in MATLAB/Simulink, Python, C, or modern C++ as appropriate.\nSupport translation of analysis algorithms into embedded, real-time software while accounting for numerical precision, coordinate conventions, scheduling, timing, initialization, and computational constraints.\nCreate unit tests, test vectors, deterministic data replays, and software-in-the-loop or hardware-in-the-loop scenarios.\nMaintain traceability between input data, model versions, sensor configurations, calibration data, software versions, test cases, and reported results.\nTest and Engineering Execution\nSupport ground and flight-test planning by defining objectives, instrumentation needs, maneuvers, expected behavior, and success criteria.\nAnalyze test data, compare measured performance with predictions, and help determine whether discrepancies come from algorithms, sensors, timing, calibration, interfaces, truth data, or vehicle dynamics.\nBreak assigned work into clear tasks, identify required inputs and dependencies, and communicate progress or blockers early.\nAsk for review when decisions exceed available evidence or experience, then incorporate feedback into the work.\nContribute to design reviews, technical documentation, shared tools, coding standards, and team learning.\nTake increasing end-to-end ownership of navigation tasks as capability and judgment grow.\nRequired Qualifications\nBachelor's degree in aerospace engineering, mechanical engineering, electrical engineering, robotics, mathematics, physics, or a related technical field.\nFoundational understanding of dynamics, linear systems, probability, statistics, estimation, coordinate frames, and numerical methods.\nExperience applying navigation, estimation, signal-processing, or sensor-fusion concepts through professional work, internships, co-ops, research, competition teams, or substantial academic projects.\nAbility to use MATLAB/Simulink or Python for modeling, simulation, data analysis, and visualization.\nExposure to C or modern C++ and an interest in developing production-quality embedded software skills.\nAbility to interpret technical requirements, check work systematically, and communicate results with supporting evidence.\nComfort working collaboratively, receiving technical feedback, and learning unfamiliar tools or concepts.\nStrong ownership, curiosity, attention to detail, and commitment to reliable engineering work.\nPreferred Qualifications\nMaster's degree in aerospace engineering, electrical engineering, controls, robotics, applied mathematics, or a related field.\nExperience with aircraft, rockets, missiles, spacecraft, UAVs, robotics, or other autonomous systems.\nExperience with Kalman filtering, inertial navigation, sensor fusion, stochastic processes, or navigation error analysis.\nExperience collecting, processing, or characterizing IMU, GNSS, or other sensor data.\nExperience with embedded systems, real-time software, hardware testing, or flight-test data.\nFamiliarity with Git, code review, automated testing, continuous integration, issue tracking, or configuration management.\nExperience with PX4, ROS 2, simulation frameworks, or student flight-vehicle programs.\nWhat Success Looks Like\nWithin your first year, you will have:\nBecome a dependable contributor to navigation algorithms, sensor analysis, software, simulation, and test activities.\nDelivered assigned navigation functions or analyses with clear assumptions, reproducible results, and appropriate review.\nBuilt a working understanding of the navigation architecture, estimator states, sensors, software interfaces, timing behavior, and verification approach.\nCreated useful tests, data-analysis tools, sensor models, or simulation improvements that increase team speed and confidence.\nUsed ground- or flight-test data to evaluate performance and improve models, calibration, or estimator behavior.\nCommunicated risks and blockers early, incorporated feedback effectively, and shown growing technical independence.\nTaken end-to-end ownership of increasingly complex navigation tasks.\nITAR Requirements\nTo conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or
