Purpose Of The Role

We’re looking for a Machine Learning Engineer to help build and scale our AI-driven solutions for high-impact clients in the legal and investment banking sectors. This role is part of a growing global engineering team, contributing to the development and delivery of cloud-native, automated AI services that are transforming how regulated industries operate.

As a Machine Learning Engineer, you’ll be hands-on — designing, coding, and deploying ML systems while working closely with DevOps, data science, and platform engineering teams. You'll also play a key role in building out our ML engineering and operations capability, with the opportunity to coach and upskill junior engineers.

We're looking for someone with a solid foundation in engineering, a passion for solving complex problems with AI, and the curiosity to keep learning and pushing boundaries.

Key Responsibilities:

• Machine Learning Development Support: Assist in designing, developing and deploying ML models and algorithms under the guidance of senior engineers to address client challenges across a range of sectors
• Cloud & MLOps Support: Help implement ML solutions on AWS (with emphasis on Amazon SageMaker). Contribute to building and maintaining CI/CD pipelines using infrastructure-as-code tools such as AWS CloudFormation and Terraform to automate model training and deployment
• Algorithm Implementation & Testing: Write clean, efficient and modular Python code using libraries such as pandas, NumPy, and scikit-learn to implement ML algorithms and data pipelines. Conduct model evaluations using metrics like accuracy, precision, and recall. Run experiments, document results, and iterate to improve performance
• Collaboration & Communication: Work closely with data scientists, ML engineers and DevOps teams to integrate models into production. Participate in sprint planning, standups, and and client calls to deliver technical updates in a clear and concise manner
• Quality, Documentation & Compliance: Maintain thorough documentation of data pre-processing steps, model parameters and deployment workflows. Follow data security best practices and ensure compliance with confidentiality requirements for highly sensitive data. Provide guidance and coaching to junior engineers. Share best practices and contribute to scaling our ML engineering capability

Required Qualifications & Experience:

• Education: Bachelor’s degree in Computer Science, Engineering, Data Science or a closely related discipline
• Experience: 2-5 years of professional experience in machine learning, AI engineering, or software development with ML exposure
• Programming & ML Skills: Proficiency in Python (including pandas, NumPy, scikit-learn). Basic understanding of ML concepts and model evaluation techniques
• Cloud & DevOps Familiarity: Hands-on experience with AWS (particularly SageMaker), and an understanding of cloud-based ML workflows. Familiarity with DevOps tools (e.g., Git, Docker) and infrastructure-as-code tools such as CloudFormation or Terraform
• Soft Skills: Strong analytical thinking, problem-solving aptitude and clear written/verbal communication. Demonstrated ability to learn quickly and work in a client-focused setting

Preferred (Additional) Experience:

• Domain Knowledge: Any exposure to regulated industries involving document classification, contract analysis or predictive analytics will be advantageous.
• Tools & Frameworks: Familiarity with version control (Git), experience working in an agile development environment using tools like JIRA, and additional MLOps frameworks (e.g. MLflow, Kubeflow) or data processing technologies (e.g. Apache Spark).

Key Traits For Success

• Strong analytical thinking and a problem-solving mindset
• A naturally curious self-learner who’s comfortable exploring new technologies
• Excellent communication skills and the ability to collaborate across global teams
• A passion for building reliable, scalable, and secure ML systems that deliver real-world value
