Tomorrow.io builds a weather intelligence and climate resilience platform combining proprietary satellite technology, advanced AI forecasting, and analytics. Our space program operates a weather observation constellation powered by next-generation sensing technologies.

We seek a GNSS Payload Engineer to support development, integration, verification, and on-orbit performance of GNSS payloads for this constellation. You will work at the intersection of GNSS, RF systems, spacecraft engineering, and atmospheric science, translating mission objectives into instrument requirements and supporting payload performance throughout its lifecycle.

What You'll Do

  • Support development, integration, verification, and on-orbit performance assessment of GNSS payload systems
  • Translate mission and scientific data needs into payload requirements, interfaces, performance budgets, and verification plans in collaboration with senior engineers and atmospheric scientists
  • Support GNSS and RF performance analyses, including link budgets, receiver sensitivity, C/N0, signal quality, interference, timing, and measurement-error assessments
  • Support design, characterization, and validation of GNSS receivers, RF front ends, antennas, timing references, and signal-processing interfaces
  • Evaluate payload performance drivers including antenna gain and patterns, multipath, EMI/EMC, oscillator stability, thermal drift, spacecraft pointing and attitude knowledge, and platform interference
  • Demonstrate understanding of payload integration and test activities, including RF signal simulation, hardware-in-the-loop testing, environmental testing, and test-data analysis
  • Demonstrate understanding of space environment effects, including thermal and radiation impacts on RF electronics, oscillators, and receiver performance
  • Work across payload, spacecraft, software, systems, and science teams to identify technical risks and resolve integration and performance issues
  • Establish and maintain clear technical requirements, interfaces, verification documentation, test results, and engineering analyses
  • Support payload activities throughout lifecycle, from design and integration through launch, commissioning, and on-orbit operations

What You Bring

  • 4-7+ years of hands-on engineering experience developing, integrating, testing, or operating GNSS, RF receiver, satellite payload, airborne sensing, or comparable signal-measurement systems
  • Strong fundamentals in GNSS signals and receiver operation, including acquisition and tracking, C/N0, link budgets, sensitivity, observables, and signal-quality metrics
  • Experience with one or more of: GNSS receivers, RF front ends, antennas, timing references, oscillators, or signal-processing interfaces
  • Working knowledge of RF and GNSS performance characterization, calibration, and validation
  • Understanding of measurement-error sources and performance drivers such as multipath, interference, oscillator stability, timing accuracy, thermal effects, and antenna performance
  • Familiarity with RF link-budget, sensitivity, noise, or interference calculations and ability to contribute to and review these analyses
  • Experience supporting complex hardware/software integration and test activities
  • Exposure to RF signal simulators, hardware-in-the-loop testing, environmental testing, or analysis of payload test data is highly valuable
  • Familiarity with environmental qualification concepts for spacecraft, aerospace, or similarly demanding engineered systems
  • Awareness of spacecraft-level considerations including EMI/EMC, antenna field of view and placement, pointing and attitude knowledge, thermal environments, radiation, and platform-generated interference
  • Ability to translate technical and mission-performance goals into clear requirements, interfaces, test approaches, and verification plans
  • Strong collaboration and communication skills, particularly when working across engineering and scientific disciplines
  • Proactive and accountable approach to engineering work, with ability to organize technical activities, identify issues, and drive them toward resolution
  • Sound engineering judgment and willingness to learn, take on increasing ownership, and grow your technical depth
