Senior ML Specialist (Data Science) IRC268898

Description

 The Green Power Solution idea is in implementing the Service that will identify delays in trains travel along the routes, caused by Temporary Speed Restrictions (TSRs) and other mid- and long-term issues, and suggest preventive compensations of such delays – to keep trains in timetable without extra accelerations and thus without extra energy consumptions.

Requirements

Job responsibilities

 We are looking for a highly skilled Machine Learning Engineer with strong expertise in classical ML methods, mathematical optimization, and reinforcement learning (RL/DRL). This role is ideal for someone who enjoys working on challenging applied research and engineering tasks involving solvers, optimization techniques, and real-world problem modeling.

Key Responsibilities

• Design, implement, and optimize algorithms for:
• Nonlinear optimization problems (both local and global solvers)
• Linear programming
• Constrained and nonlinear least-squares
• Root finding and curve fitting
• Develop and apply classical ML models as well as custom optimization-driven solutions.
• Implement and experiment with Reinforcement Learning (including Deep RL) techniques.
• Work on Causal Optimization Trees (COT) and decision-based optimization frameworks.
• Collaborate with cross-functional teams (e.g., product, data engineering, domain experts) to integrate algorithms into production systems.
• Document and communicate technical concepts clearly to technical and non-technical stakeholders.
