Senior Computer Vision Engineer - Six Floor Solutions

About the Position

Hiire is currently supporting Six Floor in hiring a Senior Computer Vision Engineer for their Six Floor Solutions team!

Six Floor Solutions builds technology that lets sports and news organizations unlock the full value of their video. Our platform uses computer vision and machine learning to process live or archived streams - automatically detecting key moments, generating highlights, and producing broadcast-ready content, with no dependency on external data feeds. We work with global broadcasters, professional clubs, and federations across football, tennis, American football, basketball, and more. We are growth-stage, our client list is expanding fast, and the product roadmap demands a stronger, more capable CV/ML team to match.

Responsibilities

• Research, design, and ship production-grade algorithms for real-time video understanding - detection, tracking, classification, segmentation - that work reliably across sports and broadcast conditions.
• Drive the continuous development and improvement of our ML models: evaluation, gap analysis, retraining, and fine-tuning. Model quality is a product priority, not a backlog item.
• Write high-performance, maintainable code in C++ (production) and Python (R&D), to a standard the whole team can build on.
• Collaborate with backend and product teams to ensure the vision pipeline integrates cleanly into the broader platform.

Team Leadership

• Lead and mentor a growing CV/ML team - setting technical direction, reviewing code, and raising the bar for delivery quality.
• Play an active role in hiring: defining roles, assessing candidates, and building a team capable of scaling with the product.
• Create a culture of rigor and curiosity - where research informs engineering and engineers care about outcomes.

Requirements

• 6+ years of hands-on experience building and shipping computer vision and/or machine learning systems in production.
• Strong proficiency in C++ (production) and Python (R&D), with solid engineering practices: version control, CI/CD, testing.
• Deep expertise in OpenCV and at least one major deep learning framework - PyTorch or TensorFlow.
• Strong fundamentals in algorithms, linear algebra, probability, and optimization - you reason from first principles.
• Experience leading or mentoring engineers, with a track record of raising team output and quality.
• Familiarity with Linux, FFmpeg, and/or GStreamer for video pipeline work.
• A Master's degree or equivalent depth in Computer Science, Electrical Engineering, or a related CV/ML field.

Nice to Have

• Experience with real-time or low-latency video at scale.
• Background in sports video, broadcast, or sports analytics.

We Offer

• Hard, unsolved problems - real-time CV and ML at scale across multiple sports and camera environments.
• Direct impact: your models will power content seen by fans of the world's biggest sports properties.
• Competitive, experience-based compensation - flexible for the right person.
• A learning culture: conferences, courses, and personal development are built into how we work.
• Flexible hours, a collaborative hybrid setup, and a tight-knit team in Lisbon that takes the work seriously without taking itself too seriously.
