Job description

ENVIRONMENT

A fast‑paced FinTech company seeks a passionate Machine Learning Engineer (MLOps focus) to power instant lending decisions—no humans in the loop. Its models drive credit risk, portfolio management and lifecycle decisioning with the biggest challenge being moving models from Data Science into reliable production systems. They’re looking for you to bridge that gap and ensure that every model built makes it into production—fast reliable and cost‑efficient. The ideal candidate will require a Postgraduate Degree in a numerate discipline such as Statistics / Mathematics / Software Engineering or a related field with 3+ years’ experience in ML Engineering, Data Engineering or Software Engineering with focus on ML deployment. You also need a proven track record of deploying ML models into production (SageMaker, Lambda, Step Functions or equivalent), strong SQL, PostgreSQL, Node.js, Python or JavaScript and AWS infrastructure (EC2, ECS / EKS, S3, Lambda, Glue, Step Functions).

DUTIES

Model Deployment & MLOps

  • Take models from Data Scientists (notebooks, prototypes) and productionize them into scalable APIs and pipelines.
  • Build CI / CD pipelines for ML : automated testing, validation, deployment, rollback.
  • Implement monitoring for data drift, model drift and performance decay with automated alerts and retraining triggers.
  • Maintain reproducible environments for training and inference (Docker, SageMaker, Lambda, Step Functions).

Infrastructure & Pipelines

  • Design AWS-native ML infrastructure optimized for cost and scale (ECS / EKS, SageMaker, Lambda, Glue, Step Functions, S3).
  • Build ETL / ELT pipelines that prepare structured and nested JSON data from PostgreSQL (BI reporting) and other sources.
  • Ensure models integrate seamlessly into real‑time decisioning engines.
  • Integration & APIs

  • Collaborate with Backend Engineers (Node.js / JavaScript) to integrate ML services into production systems.
  • Build microservices & APIs for inference, feature engineering and data transformations.
  • Ensure low‑latency, fault‑tolerant services for real‑time lending decisions.
  • Collaboration

  • Partner closely with Data Scientists to understand models, features and assumptions.
  • Work with Software Engineers to ensure production systems can consume models efficiently.
  • Act as the bridge between research and Engineering, ensuring models don’t get stuck in notebooks.
  • REQUIREMENTS

    Qualifications

  • Postgraduate Degree in a numerate discipline such as Statistics, Mathematics, Software Engineering, Computer Science or a related field.
  • Relevant AWS Certifications (e.g., AWS Certified Machine Learning – Specialty, AWS Solutions Architect).
  • MLOps-related Certifications or professional courses (e.g., Coursera, Udacity or equivalent).
  • MUST-HAVEs

  • 3+ Years’ experience in ML Engineering, Data Engineering or Software Engineering with focus on ML deployment.
  • Proven track record of deploying ML models into production (SageMaker, Lambda, Step Functions or equivalent).
  • Experience building CI / CD pipelines for ML.
  • Strong Backend / Service Development skills (Node.js, Python or JavaScript).
  • Deep experience with AWS infrastructure (EC2, ECS / EKS, S3, Lambda, Glue, Step Functions).
  • Strong SQL + PostgreSQL skills, including working with deeply nested JSON data.
  • Nice‑to‑have skills

  • Experience in FinTech, Credit or Risk Modelling.
  • Understanding of multi‑agent AI systems and advanced Feature Engineering (e.g., NLP on bank statements, credit bureau data).
  • Cost‑optimization experience on AWS.
