Senior Machine Learning Engineer (Robotics & Computer Vision)

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/Vision 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/Vision 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/Vision 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).

* Proven track record of engineering advanced Computer Vision systems within the industrial automation sector.

* 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,

* Prior leadership experience (Lead Engineer, Tech Lead) is a plus, though not required.

What we offer

* Key technical role 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.
