Senior Data Scientist CV

hace 2 semanas

Greater Madrid Metropolitan Area, España Byte & Code Solutions A tiempo completo

At
Byte & Code
, we don't do volume hiring.

We work with
carefully selected technology partners
and
exceptional professionals
who value depth, ownership, and long-term impact.

This opportunity is part of a
discreet, high-trust search
for a Computer Vision Data Scientist who will design, own, and scale advanced AI solutions used in real-world, production-critical environments.

If you care about
elegant engineering, scientific rigour, and building models that actually ship
, keep reading.

Why This Role Is Different

This is not a research-only position.

And it's not a "model-for-the-sake-of-models" environment.

You'll be operating where
mathematics, computer vision, and production engineering converge
, with real accountability over the solutions you create.

You will:

  • Work alongside a
    small, senior, and highly specialised Computer Vision team
  • Own projects
    end-to-end
    , from concept and experimentation to deployment and continuous improvement
  • Architect
    robust, scalable computer vision systems
    that automate complex operational and compliance-driven processes
  • Design both
    online and offline algorithms
    , optimised for accuracy, performance, and reliability
  • Build on a modern ML stack centred on
    Python
    ,
    PyTorch / TensorFlow
    , and cloud-native tooling
  • Operate in an environment where
    clean code, reproducibility, and maintainability
    are non-negotiable

Your Craft

We're looking for someone who treats machine learning as both
engineering and craft
.

What you bring:

  • A strong foundation in
    mathematics, statistics, and applied ML
  • Advanced experience with
    Python 3
    , including:
  • Scientific and numerical computing
  • OOP and clean architecture
  • Test-driven development
  • Performance-aware, multi-process workloads
  • Confident use of
    SQL
    for analytical and production use cases
  • Hands-on experience with
    deep learning frameworks
    :
  • PyTorch, TensorFlow, Keras
  • Model optimisation and deployment formats (ONNX, OpenVINO)
  • Solid experience with
    computer vision tooling
    :
  • OpenCV, Pillow, Torchvision
  • A production mindset, including:
  • Version control and collaborative workflows
  • Model deployment and monitoring
  • CI/CD pipelines
  • Containerisation with Docker
  • Comfort working in
    cloud-based environments
    supporting ML at scale

Signals That Make You Stand Out

These are not requirements — they are markers of depth:

  • Experience with
    HuggingFace
    ,
    Weights & Biases
    , or similar experiment-tracking platforms
  • Fluency in more than one programming language (e.g.
    Java
    )
  • Exposure to
    system design
    , distributed systems, or large-scale ML architectures
  • Curiosity and practical knowledge around modern architectures such as:
  • Vision Transformers (ViT)
  • Diffusion models
  • Multimodal and large language models
  • RetNets and emerging research directions

Offer

  • Permanent, indefinite contract directly with our client
  • Attractive and well-structured benefits package, aligned with senior-level profiles
  • Salary fully negotiable, based on experience, seniority, and expected impact
  • A dynamic environment with high autonomy, ownership, and visibility
  • Work on real-scale products, with direct influence on core technology and outcomes
