Lead Engineer – Material Science


Isotropic Systems is seeking world class candidates to join a fast-paced, proven team working on cutting edge technology in a successful startup company that brings significant opportunity for the right candidate. 

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.


Isotropic Systems is seeking an experienced Material Scientist with a focus on industrial use of microwave and millimeter-wave low-loss dielectrics and associated product development. A successful candidate will have direct background in the design, development, and volume manufacture of engineered and natural materials for use in high-volume enterprise-class products. Understanding of the available options for conventional manufacturing and the interactions between materials and the implications of decisions is a strong requirement.

A core responsibility will be the identification, specification, selection, formulation, characterization, validation and qualification of engineered low-loss dielectric materials for use with high-frequency microwave and millimeter-wave radio applications. This requires a strong understanding of methods for producing low-loss RF dielectric materials using polymer, ceramics, and foams while also meeting mechanical, environmental, manufacturing, and cost requirements. An understanding of how to achieve both large (>10) and small (<2) RF dielectric constants with specific values and low loss (<0.005 loss tangent) is required. Experience in characterizing the RF properties of candidate materials across frequency, temperature, humidity, and other environmental conditions is necessary. Hands-on experience in measuring and characterizing both mechanical and electrical properties is required.

In support for product design and development, the pairing of materials, properties, and manufacturing approaches and trading benefits of each candidate to achieve the best performance and cost available will be a key responsibility of the role. This role requires a working knowledge of the implications (polymer creep, corrosion in harsh operational environments, etc.) and requirements for material selection of common manufacturing techniques (including casting, compression molding, injection molding, machining, 3D printing, etc.).

Some products will be used in an aerospace (high-altitude or vacuum) or marine context, and so impact of material selection (metals, polymers, etc.) on product performance, longevity, and failure modes in different environments must be known and communicated among the team to allow the best design selections to be made. Ability to select materials to meet regulatory and industry standards (i.e., DO-160, MIL-STD-810) is necessary. The Material Scientist will be responsible for providing essential trades and information necessary to satisfy product requirements across all expected environmental and operational modes. Knowledge of expected cost and availability across the industry for key materials and providing input to early design decisions to minimize selection risk is critically important.

The Material Scientist 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, characterization, and mass production of a cost-effective Satcom terminal. In addition, technical leadership and subject-matter expertise is expected in the areas of dielectrics, materials, and fabrication approaches.

Essential Job Duties and Responsibilities:

  • Act as a subject matter expert with respect to all uses of and engineering of materials and their properties within the engineering organization

  • Assist in material selection for all aspects of the product design

  • Interface with internal engineers and design team, vendors, and contract manufacturers on selection and specification of materials to meet product cost, performance, and environmental targets

  • Lead in the specification, design, modeling, and characterization of low-cost microwave and millimeter-wave dielectric materials of use in our optical beamformer products

  • Innovate in material selection and formulation to enable low-cost high-performance volume manufacturing

  • Characterize the frequency, thermal, and other environmental response of the electrical and mechanical properties of RF, microwave, and millimeter-wave dielectrics.

  • Provide design guidance for the selection of materials for electrical and mechanical subcomponents that satisfy environmental and regulatory requirements

  • Interface with RF, mechanical, and manufacturing teams to contributed to development and commercialization of our product lines

  • Look outside the box for new options for achieving product requirements, in formulation, procurement, manufacturing, or fabrication processes

  • Other tasks, as assigned from time to time

Skills and/or Needed Experience:

  • MS or Ph.D. in Material Science or related discipline

  • 5+ years of experience in the fields of Material Science for Industrial Products and High-frequency Dielectrics

  • Extensive experience in working with industry standard modeling and simulation tools

  • Hands-on experience with materials characterization tools and methodologies for electrical and mechanical properties

  • Understanding of failure modes due to material changes over time, temperature, humidity, and other environmental conditions

  • Experienced in writing design and performance reports and summaries

  • Technically proficient in MS Office products

  • Practical understanding of materials and manufacturing approaches and their limits

Other Abilities:

  • Ability to communicate calmly in a well thought out response, verbal and written

  • Must have substantial problem-solving abilities

  • Proficiency with standard scientific computing toolkits, languages, and packages, such as Matlab/Python etc. (Preferred but not essential)

  • Interpersonal skills to effectively work with Isotropic staff internally as well as working effectively with suppliers and customers

  • Ability to effectively present information in team meetings and design reviews as needed

  • Ability for international travel on request (occasional)

Job Details:

  • Full-time

  • Location: United Kingdom

  • Isotropic Systems offers a highly competitive compensation package (salary and equity), excellent benefits (including comprehensive medical/dental/vision benefits, paid vacations, 401k option, stocked pantries, fridges and coffee) and an environment that recognizes and rewards your contributions.
