    Job Summary

    Job Type: Full-time

    Job Location: Linthicum, Maryland or Thames Valley, UK



    Isotropic Systems is seeking a Modem Integration Engineer with experience in integrating modems with an antenna to form an integrated SATCOM terminal. Prior experience in integrating a steered or pointed antenna, in particular an electrically-steered antenna, is a critical requirement of the role. The Modem Integration Engineer will be responsible for the requirements, preliminary design, final design, hardware implementation, software support, documentation, and relevant interfaces for the IF or baseband link between the modem and the terminal. Reporting to the Director of Terminal Management, the Modem Integration Engineer will work closely with the rest of the technical team to bring a product to market that satisfies business and technical goals and requirements.


    The successful candidate will be familiar with the common interfaces and standards of commercial SATCOM terminals and modems, and have a strong understanding of the VSAT market and ecosystem. It is expected that the candidate will be familiar with the different modem and antenna vendors within the market, and understand the differences and challenges of integration with a wide variety of disparate systems.


    As a member of the Terminal Management team, the Modem Integration Engineer will contribute to the specification, design, development, and implementation of the command and control systems within the terminal at the electrical, mechanical, and software levels. Background in embedded systems design (hardware and software) will be a strong benefit.



    The Modem Integration 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, assembly, and mass production of a cost-effective Satcom terminal. Monitoring and maintaining trends of performance across multiple product lines and customer development projects is expected.

    Develop requirements for and lead the development of integrated, modular modem bays hosted within the terminal

    Deliver technology and products that meet performance, cost and quality metrics

    Provide effective and efficient design support during the conceptual design, detailed design, integration, and test phases of a product development program, with the goal of achieving on-time and budget completion of assigned tasks

    Prepare and present design and analysis summary material during internal and external design reviews
