Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place! E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems. We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life. We are seeking a skilled and detail-oriented PV Design Engineer to be responsible for the design, optimization, and analysis of photovoltaic modules and electrical architectures for space applications.  This role focuses on module layout, electrical interconnection strategies, degradation analysis, environmental robustness, and long-term performance prediction under harsh operating conditions including radiation exposure, thermal cycling, vacuum, and UV exposure. This engineer will work closely with process, manufacturing, and systems teams to ensure photovoltaic products meet mission performance, reliability, and integration requirements. WHAT YOU'LL BE DOING: * Design and optimize photovoltaic module layouts, including series and parallel interconnection architectures.  * Define electrical configurations based on power, voltage, redundancy, and mission requirements.  * Analyze module performance using IV curves, efficiency data, degradation data, and environmental test results.  * Study and evaluate degradation mechanisms caused by radiation, UV exposure, thermal cycling, vacuum exposure, and mechanical stress.  * Support design decisions using modeling, experimental data, and reliability analysis.  * Designs systems that are manufacturable and scalable.  * Develop qualification and validation activities for harsh-environment and aerospace applications.  * Work on tools, models, and simulations for long-term performance prediction and power generation estimation.  * Define design rules, electrical margins, and failure mitigation strategies for PV assemblies.  * Support root-cause analysis related to electrical performance or reliability degradation.  * Document design assumptions, performance calculations, and engineering decisions.  WHAT YOU WILL BRING TO THIS ROLE: * BS or MS in Electrical Engineering, Physics, Aerospace Engineering, Materials Science, or related field.  * Minimum 5 years of experience designing or analyzing photovoltaic systems for aerospace, satellite, or harsh-environment applications.  * Strong understanding of photovoltaic device behavior, module electrical architecture, and system integration.  * Experience analyzing IV curves, degradation mechanisms, and long-term performance data.  * Understanding of environmental effects on photovoltaic systems including radiation, thermal cycling, and UV exposure.  * Experience working with engineering data, simulations, and reliability analysis.  * Ability to work in multidisciplinary engineering and manufacturing environments.  EXTRA POINTS FOR THE FOLLOWING: * Experience with space or satellite photovoltaic systems.  * Experience supporting qualifications or validation for aerospace applications.  * Knowledge of radiation effects on photovoltaic materials and devices.  This is a full time, exempt position, based out of our Arlington, TX office.    We are redefining how satellites are designed, manufactured and used—so we’re looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that’s your experience – then we’ll be immediately wow-ed.   E-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role. Why E-Space is right for you: As a member of our team, you will play a crucial role in driving our success.  Our team members have a strong sense of dedication and responsibility; this includes a strong commitment to our mission to create an entirely new suite of global capabilities to improve lives, business efficiencies and build a smarter planet. This means that there will be times when extra hours, including nights and weekends, may be needed to meet critical deadlines and mission goals.  In return, we offer a dynamic work environment with opportunities for professional growth and development and the chance to make a meaningful impact in a high-growth industry.   We want you to make the most of your journey at E-Space. That’s why we support and invest in the physical, emotional and financial well-being of our team members and their families.
