We are seeking a Machine Learning Engineering Intern to join our fast-growing Data Science & ML team for 6 months in a fulltime capacity. The targeted start date is March 2026 and since we value long-term growth, exceptional performance during the internship may lead to an offer for a permanent role. In this role, you’ll help build, optimize, and maintain the Python pipelines that power training data generation and FEM simulations for our quantum sensing technology. Your work will enable our ML team to rapidly prototype new ideas and validate models. This internship is an opportunity to work hands-on at the intersection of simulation, machine learning, and cutting-edge quantum sensor development.

QuantumDiamonds is one of the world’s most advanced deep-tech companies, developing quantum-sensing systems that redefine electrical fault localization and yield engineering in modern semiconductor manufacturing. Our technology visualizes current paths inside highly complex multi-layer packages, enabling engineers to understand, debug, and optimize next-generation devices faster and with unprecedented precision.

Backed by leading international investors and major public innovation programs, we are entering a high-growth phase as we prepare to ship our first series devices next year. Headquartered in Munich, Germany, QuantumDiamonds works closely with leading semiconductor manufacturers across Asia, the US, and Europe on the future of HBM, chiplets, advanced fan-out, and system-level integration.

Picture this:

• A machine that catches what others miss – in milliseconds.
• Physics, data, and engineering are working hand in hand to build tools that matter.
• An international team, who loves solving hard problems and where knowledge flows fast.

Still unsure about why joining us?

• You'll get to build a company together with a brilliant and welcoming team on a product that has never been done before.
• Our technology is the cutting edge of tomorrow, starting today and not in 10 years.
• You will work directly with major semiconductor companies from Day 1.
• You’ll be part of a high-growth company backed by top-tier investors.

Let’s make the invisible visible!

• Contribute to the development and integration of training data generation pipelines and the corresponding post-processing.
• Deep dive into FEM simulation and python script automation.
• Collaborate with machine learning engineers on Python codebases for our deep learning projects.
• Assist in testing, debugging, and improving the reliability of our ML codebase.
• Contribute to documentation, version control, and CI/CD workflows (GitHub Actions).
• Learn to understand the pitfalls and challenges of using deep learning for our cutting-edge technology.

• You are willing and able to join us for 6 months starting March 2026 in full time.
• You are a student or recent graduate in Computer Science, Electrical Engineering, Physics, or a related technical field.
• You have programming experience in Python and/or C++.
• You are eager to learn about the physics involved in our projects and building well-written ML codebases.
• You bring a hands-on, proactive mindset and enjoy solving complex technical problems.
• You enjoy working closely with a multidisciplinary team on-site in Munich.

• Mission: At QD, we’re driven by more than just building great products - we aim to make a lasting difference. Joining us means contributing to meaningful work that goes beyond business as usual.
• Impact & growth: This is an exciting stage of our journey, and your voice matters. You’ll have the chance to shape our culture, influence key decisions, and grow alongside a company that’s scaling fast.
• Health & fitness: With a company-sponsored Wellpass membership, you’ll have access to countless gyms, classes, and wellness offers across Germany to stay healthy and active.
• Team & culture: We believe the best ideas come when we connect outside the office. From regular off-sites to team events, you’ll be part of a collaborative and supportive environment
