Data Scientist

Every freight train that arrives on time and every passenger trip that ends safely depends on people, equipment, and data working together. At Wi‑Tronix, the models you train here will run on real locomotives in real time, helping crews and customers avoid the incidents that never make the news. We are hiring a Data Scientist who wants their models to leave the notebook and live on the rail.

Wi‑Tronix is the digital platform the rail industry turns to for real‑time IoT data, AI‑powered analytics, and intelligent video. This is not a typical SaaS environment, and it is not a research lab. Our work is connected to critical infrastructure, our 2026 AI roadmap is funded and shared across the company, and quality is a standard we hold each other to.

You will own the full lifecycle of deep learning models that run on locomotives across North America, working with real video and sensor data and shipping to edge hardware where lighting, weather, and equipment variability are constant factors.

• Design and train custom deep neural networks for computer vision, object detection, and time series problems
• Build and refine the labeling and training pipelines that feed model development
• Optimize models for edge deployment using PyTorch, NVIDIA Tensor
  
  RT, and ONNX
• Create the APIs and automated testing that move models into production and keep them healthy
• Partner with ML engineers, data engineers, and product, and translate model behavior for non‑technical stakeholders

• BS or MS in Computer Science, Mathematics, Statistics, or a related field
• 3+ years building and deploying deep learning models on real data, with strong Python and PyTorch fluency
• Computer vision fundamentals, SQL for data access, and experience with regression, classification, and object detection
• Solid foundation in memory model, CPU and GPU architectures, and modular software design; comfort with AWS S3 and Glue
• Agile mindset comfortable with rapid prototyping, feedback loops, and shipping work the team can act on
• Bonus: NVIDIA Tensor
  
  RT, ONNX, YOLO or Detectron2, C or C++ for edge integration, Docker, IoT or safety critical background

• A specific and real mission with locomotive video and sensor data nobody else has access to
• Full lifecycle ownership, a named career path to Senior Data Scientist, Principal Data Scientist, and AI Manager
• Benefits that back your whole life: medical, dental, and vision with HSA (employer contribution), employer‑paid life, AD&D, disability coverage, 24/7 telemedicine, an Employee Assistance Program, and financial wellness resources
• Work environment: hybrid in Bolingbrook, IL – Tuesday, Wednesday, and Thursday in office, with Monday and Friday worked remotely or on site as business needs require, occasional domestic and international travel may be required
