At Loft, we are dedicated to delivering our innovative hardware products & satellite missions on schedule and within budget. Our company is growing, and globally! That's why the role of Supply Chain Manager is crucial to our success and broadening our support across our locations. As the primary support of our operations and supply chain function in France, they will oversee several of the functions from procurement, inventory, logistics, and processes.

About this Role:

Contribute to the design and development of RF systems for satellite connectivity and payload applications, including architecture, requirements, and technical trade-offs.
Perform RF link budget analysis and evaluate subsystem performance across S-band, X-band, and inter-satellite link (ISL) applications.
Develop and optimize signal processing algorithms for RF payloads using MATLAB and related simulation tools.
Support RF payload development across the signal chain, from antennas and RF frontends to ADCs and SDR systems, including signal detection and geolocation.
Collaborate with FPGA, embedded software, and systems teams to translate RF requirements into implementable solutions and integrate signal processing algorithms.
Define and track system requirements, documenting technical decisions, integration activities, and verification results.
Support RF testing, hardware integration, troubleshooting, and performance verification through AIT and in-orbit commissioning.
Work across engineering and AIT teams to drive successful development and integration of RF systems and payloads.

Must Haves:

2+ years of experience in Radio Frequency (RF) systems engineering, subsystem integration, or a closely related field.
Proven experience with RF system integration, debugging, testing, and performance analysis.
Experience with signal processing algorithms, including the ability to model, analyze, or evaluate RF signal processing approaches.
Knowledge of RF communication systems and subsystems, particularly S-band and X-band communications.
Experience with RF link budget calculations and RF system-level performance analysis.
Hands-on experience with RF hardware, test equipment, and subsystem validation.
Demonstrated ability to independently drive technical activities and collaborate across system and software integration efforts.
Excellent communication, problem-solving, and teamwork skills.

Nice to Haves:

Experience with Software-Defined Radio (SDR) architectures and development.
Familiarity with FPGA-based signal processing, including experience working with FPGA teams to implement digital signal processing algorithms or IP blocks.
Knowledge of key SDR components and technologies, including channelizers, analog-to-digital converters (ADC), and digital-to-analog converters (DAC).
Experience using MATLAB for signal processing, modeling, simulation, or algorithm development.
Experience translating system-level RF and signal processing requirements into FPGA or embedded software implementation requirements.
Experience with antenna systems, RF frontends, and RF payload architecture.
Familiarity with RF geolocation, signal detection, spectrum analysis, or SIGINT-related applications.
Experience with RF testing, integration, and performance verification in an aerospace or satellite environment.

*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.
