Over the past 9 years, we have diligently fostered one of the largest Data Science & AI communities in Europe.

    About the role:
    We are looking for a Computer Vision / Machine Learning Engineer to develop offline CV models for industrial visual inspection.


    Your main task will be to design, train, and evaluate models on inspection data in order to:

     

    • Improve discrimination between good vs. defect samples
    • Provide insights into key defect categories (e.g., terminal electrode irregularities, surface chipping)
    • Significantly reduce false-positive rates, optimizing for either precision, or recall
    • Prepare the solution for future deployment, scaling, and maintenance
    •  

    Key Responsibilities:
    Data Analysis & Preparation
    - Conduct dataset audits, including class balance checks and sample quality reviews
    - Identify low-frequency defect classes and outliers
    - Design and implement augmentation strategies for rare defects and edge cases
    Model Development & Evaluation
    - Train deep-learning models on inspection images for defect detection
    - Use modern computer vision / deep learning frameworks (e.g., PyTorch, TensorFlow)
    - Evaluate models using confusion matrices, ROC curves, precision–recall curves, F1 scores and other relevant metrics
    - Analyze false positives/false negatives and propose thresholds or model improvements
    Reporting & Communication
    - Prepare clear offline performance reports and model evaluation summaries
    - Explain classifier decisions, limitations, and reliability in simple, non-technical language when needed
    - Provide recommendations for scalable deployment in later phases (e.g., edge / on-prem inference, integration patterns)

    Candidate Requirements:
    Must-have:
    - 1-2 years of hands-on experience with computer vision and deep learning (classification, detection, or segmentation)
    - Strong proficiency in Python and at least one major DL framework (PyTorch or TensorFlow/Keras)
    - Solid understanding of:

    • Image preprocessing and augmentation techniques
    • Classification metrics: accuracy, precision, recall, F1, confusion matrix, ROC, PR curves
    • Handling imbalanced datasets and low-frequency classes

    - Experience training and evaluating offline models on real production or near-production datasets
    - Ability to structure and document experiments, compare baselines, and justify design decisions
    - Strong analytical and problem-solving skills; attention to detail in data quality and labelling
    - Good communication skills in English (written and spoken) to interact with internal and client stakeholders

    Nice-to-have:
    - Experience with industrial / manufacturing computer vision (AOI, quality inspection, defect detection, etc.)
    - Familiarity with ML Ops/deployment concepts (ONNX, TensorRT, Docker, REST APIs, edge devices)
    - Experience working with time-critical or high-throughput inspection systems
    - Background in electronics, semiconductors, or similar domains is an advantage
    - Experience preparing client-facing reports and presenting technical results to non-ML audiences

    We offer:
    - Free English classes with a native speaker and external courses compensation;
    - PE support by professional accountants;
    - 40 days of PTO;
    - Medical insurance;
    - Team-building events, conferences, meetups, and other activities;
    - There are many other benefits you’ll find out at the interview.

    • Explore and integrate new technologies such as LLMs, MCP/A2 and AI agents to enhance our products 
    • Explore building a standalone agentic workforce for media operations  
    • Ensure data quality and integrity across multiple sources and processing stages 
    • Communicate findings and insights clearly to technical and non-technical stakeholders 
    • Assist in identifying and implementing SOTA and emerging AI/ML techniques  
    • Contribute to team-wide technical decisions, planning, and long-term strategy 

     

    This role will be a great fit if you have:  

    • 1+ years of experience in data science with a solid foundation in statistics and machine learning 
    • Proficiency in Python (and its core data/ML libraries) and SQL 
    • Hands-on experience with ETL processes, large datasets (1M+ rows), and data cleaning and validation 
    • Knowledge of frameworks like LangChain, Langraph 
    • Ability to design and customize AI agents using RAG and similar techniques 
    • Familiarity with AWS or another major cloud platform 
    • Experience with time-series forecasting, recommender systems, NLP, or optimization problems  
    • Strong communication and presentation skills, with the ability to bridge technical and non-technical perspectives 
    • Self-driven and comfortable handling tasks independently in a remote setup 

     

    We would also appreciate

    • Familiarity with Docker or Kubernetes, CI/CD pipelines, monitoring tools, and Git 
    • Previous experience with setting up MCP/A2 integrations is desired but not required 
    • Background or interest in the advertising or marketing technology space 

     

    Interview Process 

    Candidates can expect the following steps in our interview process: 

    • HR Video Interview (30 minutes): A virtual interview with HR to provide an overview of the company and the role, as well as to gain insight into your experience and background. 
    • Technical Interview with Tech team (1 hour): A virtual interview with the Data Science Team Lead and/or other Team members, focused on your technical expertise, past experience, and problem-solving approach. 
    • Offer: after completing the interview process, successful candidates will receive an offer.
