Location: Remote / EU
Stage: Early-stage startup
Product: Robotics automation platform
About the role
We are looking for a Lead Machine Learning Engineer (Robotics & Computer Vision) to join the founding technical team of a startup building a cutting-edge automation platform. Working closely with the CTO & Co-founder, you will own the product's ML core and shape its technical direction as the company scales.
To be clear: This is a highly hands-on role, not a corporate, LLM-wrapper, or prompt-engineering position.
We are looking for an ML/Deep Learning practitioner with a strong mathematical background who writes custom training loops, designs architectures (PyTorch/TensorFlow), and optimizes models for edge inference. As a primary builder from day one, your mission is to train deep learning models from scratch, develop robust computer vision pipelines, and integrate these capabilities into a commercially viable, physical robotics product within a high-performing engineering culture.
Your responsibilities
Owning the AI/ML core of the product, working closely with the CTO & Co-founder to align it with the overall technical strategy,
Writing custom training loops, designing and implementing neural network architectures (e.g., in PyTorch), and managing the end-to-end lifecycle from raw data processing to edge deployment,
Building the AI/ML components of the MVP (managing the end-to-end AI/ML model lifecycle, from architecture design to training and fine-tuning and - where relevant - hardware control interfaces),
Proposing and helping define the AI/ML stack and model architecture,
Monitoring AI, computer vision, and robotics trends to maintain a competitive technological edge,
Working closely with the CTO and, as the team grows, mentoring engineers joining the AI/ML function,
Translating customer feedback and market needs into robust AI/ML technical requirements,
Contributing to an internal culture focused on code quality, ownership, rapid iteration, and high execution standards.
Who we are looking for (must-have)
3+ years of end-to-end Deep Learning experience: From data processing and architecture design to training models from scratch and deep fine-tuning (no API prompting).
Advanced framework proficiency: Deep understanding of modern DL tools (PyTorch preferred), including writing custom data loaders and loss functions.
Computer Vision expertise: Hands-on background with CNNs, ViTs, object detection, and segmentation.
Solid software engineering foundation: Proven track record of building and shipping ML components in real, production-ready products.
Startup mindset: Pragmatic, analytical, and comfortable in fast-paced, high-uncertainty environments where rapid execution beats over-engineered code.
Language skills: Fluent Polish and English (spoken and written).
Nice to have
Experience with hardware control/integration of AI models with physical systems (robotics, embedded systems, IoT),
Experience with robotics technologies (ROS/ROS2, simulation environments, control systems),
Experience in robotics automation platforms, cloud-edge architecture, or industrial automation,
Background in deep-tech, robotics, or engineering-driven startups,
Hands-on experience in computer vision,
Prior leadership experience (Lead Engineer, Tech Lead) is a plus, though not required.
What we offer
Key technical role in the founding team of a robotics startup, with real influence over the AI/ML direction of the product,
Opportunity to build the AI/ML core of a robotics startup from scratch,
Remuneration: at least PLN 18 000 net B2B + VAT,
Equity/incentive package as the company and role grow,
Support from an experienced startup studio and capital group,
Access to industry experts and startup-building know-how,
Fast decision-making and a high-impact environment.
