About this role
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.

Turn a broad, stressful search into a focused weekly routine.
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 tuning and testing on the same acquisitions.
Implement a baseline estimator: a data-fit term combined with a regularizing prior.
Investigate additional AI/ML methods only where suitable training or validation data are available; compare them against the baseline rather than assuming they are superior.
Evaluate correction quality, residual fixed-pattern structure, stability across images, runtime, and failure cases.
Package the workflow as a prototype script or notebook with plots, quality checks, and an auditable record of inputs, parameters, and outputs.
Present findings and recommendations to EVP and CAL/VAL stakeholders; document what evidence would be needed before operational use.
The intern will gain experience in:
Radiometric calibration and CAL/VAL for space-based optical imaging.
Push-broom image characteristics and PRNU/DSNU correction.
Applied optimization and, where appropriate, machine learning for image processing.
Experimental design, reference-data limitations, and quantitative performance assessment.
Building reproducible engineering tools and communicating technical evidence to mission teams.
Must Haves:
Student in engineering, applied physics, remote sensing, image processing, data science, or a related field.
Fundamentals of signal or image processing and a strong interest in Earth observation.
Basic programming skills in Python and comfort working with scientific data.
Analytical mindset, rigor, and ability to document assumptions and limitations.
Interest in calibration, validation, sensor behavior, or image quality assessment.
Nice to Haves:
Exposure to satellite imagery or remote-sensing data.
Experience with optimization, statistical estimation, or machine-learning evaluation.
Familiarity with image-analysis libraries and scientific Python tools.
Understanding of radiometric calibration or data-quality assessment.
What Can We Offer?
You will join a stimulating environment, surrounded by passionate engineers, conducive to learning, innovation, and personal and professional development — and help build the future of space infrastructure. With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, USA | Golden, USA | and Toulouse, France.
Some of our awesome internship benefits:
Gratification: €1,300 gross/month.
Lunch vouchers (tickets restaurant), because let's be honest, we love food! (we even have a Slack channel about it: #loft-gourmand)
A genuinely international environment comprising 20+ different nationalities.
A genuine mentoring program to support you on a daily basis throughout the internship.
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.
As an international company your resume will be reviewed by people across our offices so please attach a copy in English.
