Machine Learning Engineer - ZAITRA

Career Machine Learning Engineer

Machine Learning Engineer

ZAITRA, established in 2020, is a startup with a primary emphasis on delivering tailored flight software and cutting-edge AI solutions for space missions. Our endeavours encompass projects for both the European Space Agency and commercial customers.

About the role

As a Machine Learning Engineer, you'll design and optimize AI models for deployment on spacecraft and satellites. This entails:

  • Designing, training and optimizing machine learning models for edge devices with limited computational resources.

  • Preprocessing and augmenting multispectral and hyperspectral satellite imagery at various processing levels to ensure high-quality data for ML models.

  • Working with computer vision algorithms for edge devices that serve either as a preprocessing step for ML models or as stand-alone solutions.

  • Collaborating with hardware and software engineers to integrate AI models into embedded systems.

  • Conducting research based on project needs—exploring both emerging and established methods.

  • Contributing to the technical sections of ESA proposals and final project reports (e.g., for ESA or TA CR).

  • Co-authoring our research papers and publications to share findings with the scientific community.

  • Documenting your work and contributing to the development of internal tools and frameworks.

Required qualifications

  • Solid technical background in computer science, machine learning, or a related field.

  • Proven experience in training, optimizing, and deploying machine learning models (e.g., convolutional neural networks).

  • Knowledge of computer vision principles and techniques, including traditional approaches and deep learning-based methods.

  • Strong programming skills in Python, with knowledge of ML frameworks such as TensorFlow, PyTorch, or scikit-learn.

  • Familiarity with edge AI techniques like quantization, pruning, and model compression.

  • Experience with version control systems (Git), including branching, merging, and writing clear commit messages.

  • Strong analytical and problem-solving skills.

  • Enthusiasm for space.

What we offer

  • Hybrid work (preferably with at least 3 days a week in our office).

  • Flexible working hours.

  • Modern offices near the center of Brno.

  • Direct impact on the development and direction of products for space missions.

  • Involvement in the development of solutions to be deployed in Earth's orbit and beyond.

  • 5 weeks of vacation.

  • Meal vouchers.

  • Team-building activities and company events.

What is nice to have

  • Experience in embedded systems or optimizing AI models for constrained hardware.

  • Familiarity with satellite imaging (e.g., hyperspectral, multispectral data).

  • Knowledge of C++ or Rust for high-performance model implementation.

  • Active contribution to open-source projects.

  • Understanding of ECSS.

  • Experience with model deployment frameworks (e.g., ONNX, TVM, OpenVINO, TensorRT).

  • Authorship or co-authorship of published research papers in relevant domains (e.g., AI, computer vision, or remote sensing).

Interview process

  • Submit your CV and short cover letter via email to [email protected].

  • Attend a 30-minute call with the CTO and HR.

  • Complete a short take-home task.

  • Participate in a 60-minute technical screening, including a review of your task.

  • Receive an offer.
