Janea Systems is looking for a Senior Computer Vision Engineer to join our team and support one of our clients in the sports analytics industry. In this role, you will help design, improve, and scale computer vision systems that transform sports video into actionable insights. The work will focus on video-based detection, tracking, camera calibration, homography, field registration, identity association, and adapting existing models and pipelines to new video sources, camera configurations, stadiums, and video-quality conditions.

This is a highly hands-on technical role for someone who combines strong computer vision fundamentals with practical engineering experience and the ability to drive initiatives from experimentation through production deployment. The ideal candidate is comfortable working independently, identifying weak points in existing systems, designing practical improvements, and collaborating with engineering, data, and platform teams to deliver production-ready solutions.

Location	Fully Remote/ European Residence required
Compensation	Competitive, based on experience
Work Schedule	Full time/ Flexible working hours
Reports to	Head of Engineering
Member of	Engineering Team

To be considered for this position, you must have the following qualifications:

• Strong hands-on experience building and improving production-grade computer vision systems.
• Proficiency with Python and modern machine learning frameworks such as PyTorch.
• Experience with video-based computer vision problems, including object detection, multi-object tracking, event recognition, identity association, or video analytics.
• Strong working knowledge of geometric computer vision, including camera calibration, homography estimation, projective geometry, and mapping image-space detections to real-world 2D or 3D coordinates.
• Experience designing or improving tracking systems that handle occlusions, object interactions, identity preservation, noisy detections, and missing information.
• Experience evaluating model performance, identifying failure modes, and implementing practical improvements.
• Experience adapting models to challenging real-world data where video quality, camera angles, camera placement, and environmental conditions vary significantly.
• Experience with transfer learning, domain adaptation, data augmentation, and fine-tuning models on domain-specific datasets.
• Strong software engineering fundamentals and the ability to write clean, maintainable, production-quality code.
• Ability to work independently, prioritize effectively, and drive technical initiatives to completion.
• Strong communication skills and the ability to collaborate directly with clients and cross-functional engineering teams.

Ideal candidates will also have:

• Experience working with sports video, sports analytics, broadcast video, or American football.
• Experience with multi-camera systems, image fusion, or 3D scene reconstruction.
• Experience with large-scale video processing pipelines.
• Familiarity with FFmpeg, GPU-accelerated video workflows, and inference optimization.
• Experience with OCR, scene-text recognition, jersey-number recognition, or appearance-based re-identification.
• Experience with experiment tracking and model/data versioning tools such as MLflow, Weights & Biases, DVC, lakeFS, or similar.
• Experience deploying machine learning models into production environments.
• Experience with model monitoring, performance tracking, and operational support.
• Experience designing human-in-the-loop workflows for labeling, validation, quality control, or model improvement.
• Experience acting as a technical lead, architect, or principal engineer on computer vision or machine learning initiatives.
• Familiarity with backend systems, cloud infrastructure, DevOps, or MLOps practices.

Responsibilities:

• Develop and improve computer vision models for sports video, including player and ball detection, tracking, event recognition, and identity association.
• Build and improve camera calibration, homography, and field-registration solutions that map image coordinates into normalized field coordinates.
• Analyze existing computer vision pipelines, establish baselines, identify weak links, and recommend practical improvements.
• Improve tracking robustness across different stadiums, camera placements, broadcast styles, video qualities, and environmental conditions.
• Design experiments covering data acquisition, dataset creation, augmentation, model training, fine-tuning, evaluation, and deployment readiness.
• Analyze failure modes and implement improvements that increase accuracy, reliability, scalability, and robustness.
• Adapt existing models and pipelines to support new sports, leagues, camera configurations, and video sources.
• Partner with data teams on labeling workflows, dataset quality, validation processes, and human-in-the-loop improvement cycles.
• Work closely with software, platform, and DevOps engineers to deploy computer vision models and pipelines into production environments.
• Improve inference performance, scalability, monitoring, and operational reliability.
• Establish evaluation metrics, testing processes, and quality controls to ensure model performance remains consistent over time.
• Lead initiatives end-to-end, from early technical discovery and prototyping through production deployment and ongoing improvement.
• Contribute to system design decisions that integrate computer vision, machine learning, backend services, operations, and client workflows.
• Communicate technical tradeoffs clearly with internal teams, client stakeholders, and engineering leadership.

Why join Janea? Because world-class talent deserves world-class opportunities. What we offer:

• Competitive compensation with benefits, paid vacation, and sick leave.
• The opportunity to work with a globally diverse team of top engineering talent on the industry’s toughest engineering challenges.
• Ultra-flexible working conditions – we provide a generous office equipment allowance so you can work from home, we can also provide you with a desk at an office/coworking facility near you, or use both. No business travel necessary.
• An enjoyable, start-up work environment, with excellent opportunities for professional growth and development.
• Flexible working hours – as a remote-first company, our focus has always been on getting the job done well, not when or where it gets done.
