We're looking for a technical lead who can do two hard things at once: keep a team of data scientists shipping work that holds up to scrutiny, and stay close enough to the code to know when it doesn't. You'll own the technical direction of data science projects end-to-end --- from framing the problem with the client to signing off on the modeling approach, reviewing the work, and making sure what gets delivered actually runs. This is a hands-on role. You'll still write Python, still challenge model choices, still dig into why the metrics look too good. But your biggest impact will come through others --- setting standards, mentoring the team, and making the technical calls that keep projects on track across platforms like Microsoft Fabric, Palantir Foundry, Databricks, and the major clouds. **What We Offer** AI Grant --- Stop talking about AI and start building it. Our AI Grant gives you dedicated budget and resources to turn your wildest AI idea into a working project, backed by two paid weeks to focus on nothing else. AI Center of Excellence --- Work alongside specialists in agentic AI, sovereign AI, generative and discriminative AI. This isn't a siloed team --- it's the people you'll learn from and build with daily. Your tools, your choice --- Full access to AI-powered development tools including Claude, Cursor, and GitHub Copilot. Pick what works best for you. Real project variety --- From generative AI for legal document compliance, through agentic systems in manufacturing environments, to enterprise-scale AI platforms, computer vision, and autonomous driving. You won't get bored. Conference and speaking support --- Want to attend conferences? We'll back you. Want to speak at them? Even better --- we'll support you with dedicated preparation time and bonuses. ****Your tasks**** * Own the technical direction of data science engagements: solution design, modeling approach, validation strategy, and delivery quality * Lead and mentor a team of data scientists --- code reviews, methodology reviews, career development, and raising the bar on what "done" means * Stay hands-on: prototype approaches, unblock the team on hard modeling problems, and contribute production-grade Python where it matters most * Translate client business problems into scoped, estimable data science workstreams, and push back when the problem doesn't need a model * Set and enforce engineering standards for the team: reproducibility, experiment tracking, testing, and documentation * Guide platform decisions and delivery across cloud/data ecosystems --- Microsoft Fabric, Palantir Foundry, Databricks, Snowflake, and native Azure/AWS/GCP services * Work with AI Architects, data engineers, and client stakeholders to align technical decisions with business outcomes and timelines * Represent the team in front of clients: present results, defend methodology, and manage technical expectations **Requirements** * At least 6 years in data science with a track record of models shipped to production, including a minimum of 2 years leading or mentoring other data scientists * Deep, hands-on Python skills across the standard data stack (pandas, NumPy, scikit-learn, XGBoost) --- you can still review and write the hard parts yourself * Strong statistical and ML foundations: experimental design, validation methodology, and the judgment to spot results that won't survive contact with reality * Familiarity with at least one cloud/data platform and its data science components --- Azure (Microsoft Fabric, Azure Machine Learning), AWS (SageMaker), GCP (Vertex AI, BigQuery ML), Snowflake (Snowpark ML, Cortex), Databricks (MLflow, Mosaic AI), or Palantir (Foundry Code Workspaces, Foundry ML, AIP) * Experience leading delivery in a client-facing or consulting context: scoping, estimation, and managing technical risk * Strong communication skills --- able to defend a methodology to a technical audience and explain its business impact to a non-technical one * Fluent English (both written and spoken) * Fluent Polish required * Residing in Poland required **Nice to have** * Production experience with Microsoft Fabric or Palantir Foundry, or relevant platform certifications * Experience with MLOps at team scale: CI/CD for ML, model registries, monitoring, and governance * Exposure to GenAI/LLM projects and judgment about where they do --- and don't --- belong in a data science solution * Public technical presence: conference talks, publications, or open-source contributions Job no. 260612-02LZT Sii ensures that all hiring decisions are made solely on the basis of qualifications and competence.

We're looking for vision engineers who know that not every problem needs a neural network --- and that some problems can't be solved without one. You'll work across the full spectrum of computer vision: classical geometric methods like camera calibration, stereo, and multi-view geometry, alongside modern deep learning for detection, segmentation, and tracking. Knowing which tool fits which problem is exactly the judgment we're hiring for. Our vision projects are not academic exercises. They run on factory floors, in vehicles, and on edge devices with real latency and accuracy constraints --- from quality inspection in manufacturing through autonomous driving perception to enterprise-scale image and video analytics. **What We Offer** AI Grant --- Stop talking about AI and start building it. Our AI Grant gives you dedicated budget and resources to turn your wildest AI idea into a working project, backed by two paid weeks to focus on nothing else.

You won't get bored. Conference and speaking support --- Want to attend conferences? We'll back you. Want to speak at them? Even better --- we'll support you with dedicated preparation time and bonuses. ****Your tasks**** * Design and implement vision systems combining classical and learning-based approaches --- choosing the right method for the constraints of each problem * Apply geometric computer vision in practice: camera calibration (intrinsic/extrinsic), stereo and multi-view geometry, feature detection and matching, pose estimation, structure-from-motion, and visual SLAM * Build, train, and fine-tune deep learning models for object detection, semantic and instance segmentation, multi-object tracking, OCR, and anomaly detection using PyTorch * Develop image processing pipelines with OpenCV and NumPy: filtering, morphology, thresholding, contour analysis, and color space operations * Optimize models and pipelines for deployment: quantization, pruning, ONNX/TensorRT conversion, and real-time inference on edge devices and GPUs * Own data quality end-to-end: dataset design, annotation strategy, augmentation, and systematic error analysis on real-world imagery * Build evaluation frameworks that measure what matters in production --- not just mAP on a benchmark, but failure modes under real conditions * Collaborate with AI Architects and ML engineers to integrate vision components into larger systems, on-prem and in the cloud **Requirements** * At least 5 years in computer vision engineering, with vision systems shipped to production --- not just research prototypes * Solid grounding in geometric vision: projective geometry, camera models, epipolar geometry, and 3D reconstruction fundamentals * Hands-on deep learning experience: training and deploying CNN- and transformer-based models (e.g., YOLO family, Mask R-CNN, DETR, SAM) for real applications * Strong Python and OpenCV skills; comfort with PyTorch and the surrounding ecosystem (torchvision, Albumentations, ONNX) * Experience optimizing inference for constrained environments --- latency budgets, embedded hardware, or high-throughput video * The judgment to pick a homography over a transformer when the problem calls for it --- and to defend that choice * Ability to work autonomously while collaborating effectively with architects, engineers, and product teams * Fluent English (both written and spoken) * Fluent Polish required * Residing in Poland required **Nice to have** * C++ skills for performance-critical pipelines and integration with existing vision systems * Previous work with visual SLAM, sensor fusion (LiDAR, radar, IMU), or autonomous driving perception stacks * Exposure to vision-language models (CLIP, Grounding DINO) and foundation-model-based labeling or zero-shot pipelines * Experience deploying on NVIDIA Jetson, industrial cameras (GenICam/GigE), or cloud vision services on Azure, AWS, or GCP Job no. 260612-LXSXE Sii ensures that all hiring decisions are made solely on the basis of qualifications and competence.

We're looking for data scientists who turn ambiguous business questions into models and analyses that actually get used. You'll frame the problem, wrangle the data, build and validate models, and --- just as importantly --- explain what the numbers mean to people who don't speak Python. Your day-to-day will revolve around the classic Python data stack: pandas, NumPy, and scikit-learn. You'll also work on modern enterprise data platforms --- running notebooks and lakehouse workloads in Microsoft Fabric, building pipelines and operational applications in Palantir Foundry, and deploying analytics on Azure, AWS, or GCP. The science matters, but so does making it work inside a real organization's data ecosystem. **What We Offer** AI Grant --- Stop talking about AI and start building it.
