Job Description

We are innovators, we do what we do because we believe in a connected world. Our mission is to provide innovation that extends the global reach of connectivity for our customers. We are looking for world class talent to join our high-performing team working on cutting edge technology in the satellite communications industry. We stand by our company values; PASSION, RESPECT, BOLDNESS, INTEGRITY & CREATIVITY - giving you the opportunity to build your career in an environment where we encourage crisp decision-making, challenging the status-quo, championing your beliefs and ideas, sharing successes (and learning from failures) and working collaboratively with your fellow team members. We are pioneering the introduction of innovative and disruptive low-profile multiple-beam satellite communications terminals for mobile and fixed applications. These highly integrated terminal systems combine elements of new advances in microwave lens optics, phased array antenna technology, and dynamic beam pointing control systems using analog and/or digital signal processing. Our terminal designs operate as fully electronic beam steering systems. Our IP has applications across a wide range of market sectors including: aeronautical, land mobile, maritime, and 5G, providing broadband, multi-beam, two-way communications with dynamic tracking of geostationary and non-geostationary satellites or terrestrial nodes. Opportunity Isotropic Systems is seeking a Control Systems Engineer with experience in developing control systems relevant to satellite ground terminals. In this role they will specify, design, and implement beam pointing and satellite tracking control systems for mobile SATCOM terminals using both geo-synchronous and non-geosynchronous orbit satellite constellations. This position will report to the Director of Terminal Management and will collaborate closely with the Active Microwave and Systems Engineering teams to implement the necessary interfaces, hardware, and software to meet product and regulatory requirements. Background in beamforming from Electrically Steered Antennas (ESA) and maintaining satellite links using stabilized reflectors will be useful for this role. Designs and implementations of the antenna beam pointing and tracking system must be performed with understanding of expected physical, mechanical, and electrical tolerances, in the presence of noise, shocks, and vibrations and multiple error sources. Phased array beamforming requires knowledge of and compliance with the relevant FCC and ITU regulations for the power-spectral density (PSD) masks for transmit mode, and maximum efficiency in receive mode. The requirements for the tracking system are specified by the environment and regulatory masks, which must be flowed down to the terminal subsystems. The Control Systems Engineer will also contribute to the development of calibration processes (real-time and factory calibration) to ensure accurate beam pointing at all times. The Control Systems Engineer is expected to bring a high degree of creativity and problem-solving capability to search outside the box for new solutions to questions in the design, testing, and calibration of a cost-effective, high-performance Satcom terminal. In addition, technical leadership is expected in the areas of analysis of complex Antenna systems for all-electronic antenna systems and motion-controlled stabilized platforms, and monitoring and maintaining trends of performance across multiple product lines and customer development projects. Essential Job Duties and Responsibilities: * Specify detailed requirements for the pointing and tracking control system for Isotropic's electrically-steered SATCOM terminals * Develop functional and performance models of pointing and tracking subsystems for testing algorithms and control software * Determine tracking architecture, algorithms, and implementation methods * Design pointing and tracking systems to meet requirements * Determine hardware and software requirements * Interface with Active Microwave Circuits team to provide necessary control signals to command and control the beamforming operations * Organize production quality software development supporting the pointing, tracking, and control. Requirements * BS or MS in Electronic, Systems, or related Engineering discipline * 5 years+ commercial or equivalent experience in the design of control systems, ideally for satellite applications * Demonstrated capability in pointing and control techniques and methodologies relevant to SATCOM ground terminals * Demonstrated strong capability in the relevant mathematical techniques and the development of computing algorithms to implement these in real time. * Demonstrated knowledge of satellite orbital dynamics. * A strong understanding of sources of measurement error and noise. * Translation of product requirements and specifications into technical requirement and specifications * Extensive experience in working with industry standard mo
