Loft Orbital is revolutionizing access to space by building reliable, shareable satellites that drastically reduce the time and complexity traditionally required to get to orbit. We operate satellites, fly customer payloads, and handle entire missions from end-to-end. We’re a close-knit team of space enthusiasts, software experts, and cutting-edge technologists, all working together to make space simple for our customers.
As a Senior Security Engineer on our Security and Compliance Team, your mission will be to ensure that our highly automated, containerized, and globally distributed infrastructure remains secure throughout its lifecycle, from architecture to incident response. You’ll be at the heart of our DevSecOps efforts, collaborating directly with infrastructure, software, product, and solution teams to scale Loft’s security maturity while embracing our startup agility and culture.
This is a hands-on, deeply collaborative role, offering broad scope, rapid growth opportunities, and yes, a chance to contribute to space missions
About the Role:
Lead the assembly and integration of RF subsystems and components into the spacecraft.
Ensure proper installation, wiring, and connectivity of RF hardware according to design specifications.
Develop test plans and procedures for RF systems and components.
Conduct comprehensive RF tests to verify system performance, including sensitivity, signal-to-noise ratio, and frequency response.
Troubleshoot and resolve RF hardware issues during testing.
Prepare RF hardware for environmental testing, including thermal vacuum testing, vibration testing, and electromagnetic interference (EMI)/electromagnetic compatibility (EMC) testing.
Analyze and report on environmental test results to ensure RF systems meet specified requirements.
Collaborate with RF system architects and design engineers to perform system analysis and simulations for performance optimization.
Work closely with cross-functional teams, including electrical engineers, mechanical engineers, and system engineers, to integrate RF systems into spacecraft successfully.
Hands-on experience with space hardware and spaceflight antennas, with a strong understanding of design intent.
Proficiency in test engineering, including test design, validation, execution, and troubleshooting.
Experience with tests such as EMI/EMC, GNC GPS testing, and TTNC (tracking telemetry and control).
Knowledge of relevant software for testing and analysis.
Familiarity with electrical check-out procedures and environments, though emphasis lies more on rigorous testing rather than environmental testing.
Must Haves:
Bachelor’s degree in Electrical Engineering, Aerospace Engineering, or a related field. Master’s degree preferred.
Minimum of 5 years of experience in RF subsystem testing and integration.
Proven experience in RF system integration, simulation, and performance analysis.
Experience in payload RF systems, transceiver, and amplifier design.
Proven experience with RF testing tools (VNA, Spectrum Analyzer, RF chamber)
Knowledge in EMI/EMC characterization is a real plus for this position
Excellent communication and teamwork skills.
Nice to Haves:
Experience in Signal Processing algorithms
*Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Loft, we value respectful debate and people who aren’t afraid to challenge assumptions. We strongly encourage you to apply, even if you don’t check all the boxes.
Who We Are
Loft: Space Made Simple.
Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit.
We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 30 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives.
With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure.
