About the Company
Stratospheres Inc. is a mission-driven startup focused on developing low-cost, scalable systems to study weather and climate. We launch stratospheric balloons, track and control their movement, and keep them at fixed positions for long duration to collect continuous atmospheric data. We also build physics-based models to simulate and understand weather and climate conditions.
About the Role
We are looking for an RF Communications Engineer to design, develop, and test long-distance wireless communication systems for high-altitude sensing platforms. You will work across RF, antenna, embedded, and systems engineering teams to deliver reliable long-range telemetry, command, and data links.
This role includes RF hardware design, link-budget modeling, antenna development, and signal-processing implementation — along with field testing to validate end-to-end system performance.
Please include a short cover letter explaining your interest and relevant experience.
Applicants must be legally authorized to work in the United States. We are unable to provide visa sponsorship at this time.
Key Responsibilities
- Design and develop RF antenna systems, high-frequency links, and communication payloads
- Build and test receiver chains, demodulators, and RF front-end components
- Develop and optimize signal-processing algorithms for long-range communications
- Perform link-budget analyses, propagation modeling, and system simulations
- Integrate RF hardware with embedded systems, sensors, and flight electronics
- Conduct lab and field testing of communication systems, including validation flights
- Evaluate new RF technologies and integrate them into long-distance communication architectures
- Collaborate with systems, avionics, and software engineers to ensure robust telemetry and command links
Required Qualifications
- Bachelor’s degree in Electrical Engineering (EE) or related field
- Strong understanding of RF engineering, wireless communication, and electromagnetic principles
- Experience with Ka/Ku, W, and/or V band communication systems
- Hands-on experience with RF test equipment (spectrum analyzers, VNAs, signal generators)
- Knowledge of RF signal processing, modulation/demodulation, filtering, and DSP techniques
- Ability to model and simulate RF links (MATLAB, ADS, CST, HFSS, GNU Radio, or similar)
- Programming experience (Python, MATLAB, C/C++)
- Ability to analyze systems from first principles
- Comfortable with field testing and occasional irregular hours during experiments
