Join to apply for the Senior Machine Learning Engineer role at Compare the Market

Location: Hybrid / London or Peterborough

Team: Data & AI

Why this role matters

At Compare the Market, we’re scaling our AI capabilities to power intelligent, personalised experiences that help millions make smarter financial decisions. As a Senior Machine Learning Engineer, you’ll play a critical role in enabling the deployment, monitoring, and scaling of production-grade ML systems—making sure that our AI ambitions are not only possible, but production-ready.

This role blends hands-on engineering with architectural design, experimentation support, and MLOps best practices. You’ll work closely with data scientists, platform engineers, and product teams to build the infrastructure and tooling that powers our most advanced models. You’ll also contribute to technical standards, advocate for scalable and responsible ML development, and help shape a high-performance ML Engineering function.

What You’ll Be Doing

 ML Engineering & Deployment

  • Own the end-to-end delivery of production ML solutions in collaboration with data scientists and product teams
  • Design and build model pipelines for training, validation, and deployment using modern tooling (e.g. MLflow, Kubernetes, Airflow)
  • Contribute hands-on code to model packaging, deployment, and lifecycle automation
  • Build systems that monitor model performance, drift, and operational health in real time
  • Support both batch and real-time ML workloads depending on use case requirements


Platform & Standards

  • Define and promote best practices for reproducibility, testing, CI/CD, and model observability
  • Help evolve our internal ML platform to support experimentation, governance, and collaboration
  • Develop shared tools and libraries that accelerate safe, efficient, and scalable ML development


Collaboration & Technical Leadership

  • Work closely with data scientists to productionise experimental models and turn prototypes into robust services
  • Act as a technical mentor and code reviewer for other engineers and contributors
  • Provide architectural guidance across multiple ML projects and technical design sessions


Culture & Innovation

  • Contribute to a culture of engineering excellence, collaboration, and learning
  • Stay up to date on emerging tools and approaches in MLOps and applied AI
  • Support responsible AI practices by contributing to explainability, auditability, and fairness initiatives in ML systems


What We’re Looking For

Must Have

  • Strong experience deploying ML models into production in cloud-native environments
  • Solid software engineering skills in Python (and optionally one other language, such as Go or Java)
  • Experience with modern ML tooling (e.g. MLflow, TFX, Airflow, Kubeflow, SageMaker, Vertex AI)
  • Familiarity with CI/CD pipelines and infrastructure-as-code (e.g. Terraform, CloudFormation, GitHub Actions)
  • Experience building robust, maintainable, and testable ML pipelines and APIs, including batch or real-time model delivery
  • Strong understanding of ML lifecycle challenges—versioning, testing, monitoring, governance
  • Excellent collaboration and communication skills; able to work across disciplines


Nice to Have

  • Experience working in regulated sectors such as insurance, banking, or financial services
  • Familiarity with platforms such as Databricks, SageMaker, Vertex AI, or Kubeflow
  • Experience deploying real-time or streaming ML models (e.g. Kafka, Flink, Spark Structured Streaming)
  • Exposure to large language models (LLMs), vector databases, or RAG architectures
  • Passion for automation, tooling, and building reusable systems
  • Interest in responsible AI and ML model governance


Why Join Us?

You’ll be joining a modern, fast-growing ML Engineering team that’s powering real-world AI at scale. With the right tools, support, and technical autonomy, you’ll help shape how we turn experimental models into trusted systems that deliver impact across our platform.

Everyone Is Welcome

We’re committed to building a diverse and inclusive Data & AI team where everyone feels they belong. If this role excites you but you don’t meet every single requirement, we still encourage you to apply. We care about what you can do—not just where you’ve been.

The Future of Machine Learning Jobs: Careers That Don’t Exist Yet

Machine learning (ML) has become one of the most powerful forces reshaping the modern world. From voice assistants and recommendation engines to fraud detection and medical imaging, it underpins countless applications. ML is no longer confined to research labs—it powers business models, public services, and consumer technologies across the globe. In the UK, demand for machine learning professionals has risen dramatically. Organisations in finance, retail, healthcare, and defence are embedding ML into their operations. Start-ups in Cambridge, London, and Edinburgh are pioneering innovations, while government-backed initiatives aim to position the UK as a global AI leader. Salaries for ML engineers and researchers are among the highest in the tech sector. Yet despite its current importance, machine learning is only at the beginning of its journey. Advances in generative AI, quantum computing, robotics, and ethical governance will reshape the profession. Many of the most vital machine learning jobs of the next two decades don’t exist today. This article explores why new careers will emerge, the roles likely to appear, how today’s roles will evolve, why the UK is well positioned, and how professionals can prepare now.
