Machine Learning Engineer to $4700

You’ll join a modular, data-intensive platform that optimizes large-scale operations (e.g., energy/transport scheduling) via mathematical optimization. The system streams high-quality telemetry, schedules, costs, and alerts - creating ground for ML that enhances forecasting, risk assessment, and decision support. No ML is in production yet; you’ll help design and ship the first wave.

Responsibilities

• Translate business/optimization needs into ML problems
• Design and own end-to-end data/feature pipelines
• Build, validate, and productionize models for forecasting, classification, and anomaly detection on operational data
• Define evaluation metrics and experimentation loops (offline simulation, A/B tests, post-deployment monitoring)
• Integrate models into microservices and optimization workflows (batch/real-time inference, APIs, containers)
• Establish MLOps foundations: versioning, CI/CD, monitoring, and drift detection.
• Collaborate closely with domain/optimization engineers and stakeholders to ensure models drive measurable impact

Personal Profile Overview

• Comfortable owning the full ML lifecycle (problem framing, data, model, deploy, observe)
• Degree in Data Science, Computer Science, Software Engineering or related field
• Stability in previous employment history with a tendency to remain with employers for extended periods
• Experience in managing diverse project activities (not just coding, but also requirements analysis, preparing estimations)
• Clear and effective communication skills, both verbal and written, and ability to convey ideas, information, and messages accurately and efficiently
• Proficiency in fostering effective collaboration and teamwork activities
• Ability to analyze information, assess situations, and make decisions based on sound reasoning and logical evaluation
• Focus on delivering exceptional customer experiences and prioritizing customer satisfaction
• Analytical thinking, problem-solving abilities, and strategic approach to technical challenges
• Transparency in sharing information within a team and company
• Willingness to acquire new knowledge and insights to enhance professional growth and performance

Required skills

• 3+ years of hands-on experience in applied machine learning, particularly with structured and time-series data
• Experience developing models for forecasting, classification, or anomaly detection in real-world production systems
• Strong experience with time-series modeling and feature engineering, including resampling, time-aligned joins, and handling irregular or sparse data
• Proficiency in error analysis and debugging ML models, including use of metrics like MAE, RMSE, F1, ROC-AUC, and calibration curves
• Understanding of model explainability tools and techniques (e.g., SHAP, permutation importance, feature contribution tracking)
• Experience with ML versioning and reproducibility tools (e.g., MLflow, DVC, Weights & Biases)
• Familiarity with cloud-based ML infrastructure (AWS/GCP/Azure).
• English Upper-Intermediate (B2)

As a plus

• Experience with energy/EV charging domain
• Experience with reinforcement learning in optimization settings
