About this opportunity
Fortastra Corporation lists this Senior RF Engineer opportunity in los angeles, California. Review the employer’s description below for duties, qualifications and application requirements.
Job description
Fortastra designs and delivers resilient, high-performance spacecraft that safeguard critical orbital assets and ensure freedom of action in space. We integrate advanced autonomy, sensing, and control into systems engineered for reliability, speed, and scale.
Our culture values simplicity, accountability, and disciplined execution. We expect leaders to think systemically, act decisively, and take ownership of mission outcomes. Aggressive innovation. Disciplined execution. Strength among the stars.
You’ll join Fortastra’s Engineering Division. The RF and communications function is responsible for getting data to and from our vehicles and between them in orbit. This includes spacecraft TT&C links to the ground, crosslinks between vehicles, and RF payloads that enable resilient operations in contested environments.
The Role
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.
Key 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.
Qualifications and Skills
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.
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.
Ability to work across disciplines with mechanical, digital, software, and systems engineers to deliver integrated RF solutions.
Requirements
5 days on-site in Torrance, CA
Why Fortastra
We are a small, high-impact team building the next generation of autonomous orbital control systems for national security space. At Fortastra, leaders own outcomes from first principles through flight and directly shape the future of resilient, mission-critical spacecraft autonomy.
FORTASTRA TALENT & CULTURE PRINCIPLES
Values Driven by First Principles
We value engineers and operators who prioritize sound judgment, candor, technical rigor, bias for action, and intellectual honesty over corporate consensus. We care about the caliber of the system you build and the speed at which you solve problems.
Talent Density Over Headcount
A high-performing startup is built on dense talent, not organizational bloat. A single exceptional engineer designs, tests, and delivers faster than a bloated committee. We intentionally maintain a lean, elite engineering crew where every contributor directly moves the needle on the mission.
We hire domain experts to execute, not to micromanage them. You own your systems end-to-end, from initial architecture and hardware design to testing and deployment. With absolute ownership comes the responsibility to deliver mission critical reliability.
Mission Context Over Bureaucracy
The best execution happens when teams are provided clear technical objectives, constraints, and operational context, rather than rigid top-down policies. We strip away red tape so builders can iterate, make decisions, and push hardware and flight software forward rapidly.
Disciplined Speed & Flight Rigor
We move fast because we test often and kill artificial bottlenecks, not because we cut corners. Rapid iteration on the test stand and in simulation is how we learn; an uncompromising flight‑ready bar is how we earn trust. Precision without friction, speed without recklessness.
You don’t come to Fortastra to climb a corporate ladder or manage slide decks; you come to build complex, flight‑ready systems from day one. Growth here is organic, driven by the magnitude of technical challenges you solve and the trust you build across the team.
We take care of our employees so they can focus on what matters most: family, well-being, and life outside of work.
