Senior RF Engineer
About The Position
Fortastra is seeking a Senior RF Engineer to own the end to end design and implementation of RF communications systems for our spacecraft. You will be responsible for TT&C links to the ground as well as RF crosslinks between vehicles, including architecture, link budgets, radio selection or design, and antenna integration. This is a hands-on, system-level role that spans analysis, hardware selection, and integration. You will define RF architectures, perform detailed link analyses, select and integrate COTS radios or design custom solutions where needed, and ensure that our communications systems perform reliably in orbit. Experience with electronic warfare payloads, FPGA-based signal processing, or antenna design is highly desirable.
Requirements
- B.S. or M.S. in Electrical Engineering, RF Engineering, or a closely related field.
- 5+ years of experience in RF system design for spacecraft, satellite communications, defense communications, or similar high-reliability RF systems.
- Strong experience performing link budget analysis for RF communication systems, including space to ground and preferably crosslinks.
- Familiarity with common space communications protocols and standards such as CCSDS and DVB-S2.
- Experience with RF hardware selection and system integration, including radios, LNAs, PAs, filters, and related front-end components.
- Experience with one or more RF design and analysis tools (for example STK, SystemVue, MATLAB, or similar) for link analysis and system trades.
- Ability to work across disciplines with mechanical, digital, software, and systems engineers to deliver integrated RF solutions.
- 5 days on-site in Torrance, CA
- U.S. Citizenship required
Nice To Haves
- Experience with antenna design or integration is a strong plus, including understanding of antenna patterns, gain, and polarization.
- Experience with FPGA based implementation of RF or EW algorithms is a plus.
- Exposure to electronic warfare, RF signal analysis, or payload development is highly desirable.
Responsibilities
- Own the RF architecture for spacecraft TT&C and crosslink communications, from concept through flight.
- Perform detailed link budget analysis for space to ground links and inter-satellite links, including margin assessments and sensitivity to environment and geometry.
- Select, architect, and integrate radios for TT&C and crosslinks, combining COTS hardware with custom designs where required.
- Define and implement communications schemes using common space protocols such as CCSDS and DVB-S2.
- Develop system level RF requirements, interface definitions, and performance budgets for radios, antennas, and front-end hardware.
- Work with mechanical and systems engineers to design antenna placements, mounting, and panel integration, and to account for pointing, blockage, and thermal constraints.
- Support antenna selection or design, including trades on patterns, gain, polarization, and frequency bands.
- Collaborate with digital, FPGA, and software teams to implement waveforms, modulation, coding, and EW related algorithms in firmware and software.
- Support or lead RF test activities including bench characterization, over-the-air tests, and system level validation of links in relevant environments.
- Contribute to resilience in contested environments by informing or developing EW related capabilities where appropriate.
Benefits
- Unlimited Paid Time Off
- Comprehensive Healthcare: Medical, dental, and vision coverage for you and your dependents
- Equity: Share in Fortastra's success with equity in the company you're helping build.
- 401(k)
- Social Events: Regular social events, team outings, and company-sponsored activities
