Wanna join the adventure? Loft Orbital is looking for a Backend Engineering Intern to join our Ground Platform, Control Team. The Control team owns the backend services that let Loft operators and customers command, monitor, and automate our satellite fleet through Cockpit, our mission control system. You'll help build and scale the microservices that sit between ground and flight software, turning high-level intent into safe, reliable on-orbit operations. Our team sits in the middle of Flight Software, Satellite Operations, and Test teams, giving you the chance to learn about the full end-to-end systems that go into launching and operating a satellite mission. If you're excited about building backend systems that directly control satellites — and you like the idea of both shipping code and helping fly missions — we'd love to hear from you. Location: Toulouse office, city center (Jeanne d’Arc metro station) Duration: 6-month, end-of-studies internship — target start...

Wanna join the adventure? Loft Orbital is looking for an intern to join the End-to-End Validation & Performance (EVP) team and contribute to image-processing and calibration/validation (CAL/VAL) activities for Earth-observation missions. In this internship, you’ll explore how AIT captures and routine onboard imagery can support optical performance testing and radiometric calibration, and turn that work into an evaluated engineering prototype. Location: Toulouse office, city center (Jeanne d’Arc metro station) Duration: 6-month, end-of-studies internship — target start date: early 2027.   About this role: Review DSNU, radiometric calibration, and relevant EVP processing and CAL/VAL practices. Work with EVP engineers to identify suitable routine images, metadata, and reference calibration data; document data limitations and provenance. Prepare a reproducible dataset and establish reference baselines, including a holdout evaluation strategy that avoids...

Wanna join the adventure? Loft Orbital is making space simple. We build and operate reliable, shareable satellites that give customers a faster, simpler path to orbit. By combining flight-proven spacecraft platforms with our own hardware and software, we make it easier to deploy missions in space. As an RF Systems Engineer, you'll contribute to the design, development, and integration of communication systems across our satellite connectivity and next-generation RF payload programs. You'll work on RF system architecture, signal processing algorithms, and performance analysis, collaborating closely with FPGA , embedded software, systems, and hardware engineers to develop and integrate complex RF technologies. This role is ideal for an engineer who enjoys working at the intersection of RF hardware and signal processing, solving challenging technical problems, and seeing their work go from initial design to in-orbit operation.   About this Role:...

Wanna join the adventure? At Loft Orbital, we're on a mission to make space simple. We develop and operate innovative satellite missions, and our success depends on delivering high-quality hardware and services on time and within budget. As we continue to expand globally, we're looking for a Supply Chain Manager to support our growing operations in France. In this role, you'll take ownership of key supply chain activities, with a particular focus on supplier negotiations, procurement, inventory management, and international logistics. You'll work closely with our engineering, manufacturing, quality, and global supply chain teams to ensure materials and equipment are available when needed, suppliers meet our expectations, and shipments move efficiently across borders. We're looking for someone who enjoys being hands-on, thrives in a fast-paced technical environment, and can balance day-to-day execution with continuous improvement.   About this Role: Supplier...

Wanna join the adventure? Loft Orbital flies other people's payloads on standardized satellites, giving our customers a fast, simple, and reliable path to orbit. Our AI for Space team is looking for a motivated intern to explore how fast, lightweight “System 1” models can boost reactivity, performance, and usability across our satellite operational chains. Reactivity use cases are at the heart of Loft's vision, and we are scaling them: from single-satellite reactive loops, to two-satellite / two-sensor tip & cue (a detection from one sensor automatically cueing an acquisition by another), and ultimately multi-satellite scenarios. Today we mostly rely on “System 2” models — powerful but slow and heavy at inference — from our partners. “System 1” models (fast, intuitive) are coming back strongly and could add value not only on reactivity, but also on performance and ease of use. This internship will assess that added value and prototype it on our reactivity scenarios....

Wanna join the adventure? The RF team at Loft Orbital designs and integrates antennas across frequency bands, from VHF to X-band, onto satellite platforms. Besides single antenna elements, the team also designs arrays for DOA -based RF emitter geolocation from LEO. Loft has already designed and manufactured L/S and S/C antenna arrays and now wants to support X-band. This is where you come in! You will work closely with senior engineers from the  RF team and propose new antenna designs for future missions. Based on papers available in the scientific literature and commercial EM simulation tools, you will have the mission to simulate and validate those antenna concepts. These tasks are critical to saving valuable engineering time for the RF team, and your contributions will directly impact the future of upcoming RF payloads. Location: Toulouse office, city center (Jeanne d’Arc metro station) Duration: 6-month, end-of-studies internship — target start date: early...

BACKGROUND This initiative was announced as part of the “ 50 Years of ESA/100 year Roy Gibson, Session – Roy Gibson – The Golden Age of EO ” session moderated by Volker Liebig, at the ESA Living Planet Symposium in June 2025, and in the presence of ESA Director General, Josef Aschbacher, and ESA Director of Earth Observation Programmes, Simonetta Cheli , with impressive participation from international leaders who shaped space and the golden age of earth observation.   The Fellowship, in honour of Roy Gibson – the first Director General of ESA, serving from 1975 until 1980 – recognises the critical importance of space policy and diplomacy in times of unprecedented geo-political and geo-economic shifts, which also affect space. Its purpose is to harness excellence in research and policy analysis that will contribute to ESPI’s overall vision of building a strong Europe as a Trusted Partner to the World. A joint ESPI-ESA initiative , the Fellowship will :...
