  • Designing and developing machine learning algorithms and models.
  • Collaborating with data scientists to preprocess and analyze data.
  • Testing and validating ML models to ensure accuracy and reliability.
  • Integrating ML models into software systems or products.
  • Monitoring model performance and making improvements over time.
  • Researching new tools and techniques to advance ML capabilities.
  • Documenting processes and communicating findings to stakeholders.

Salary

Salaries for machine learning engineers reflect the demand for their expertise.

  • Entry-level roles: £35,000–£50,000 per year.
  • Mid-level roles: £50,000–£80,000 per year.
  • Senior roles: £80,000–£120,000+ annually.

Specialized skills, such as deep learning or experience with large-scale systems, can command higher salaries.

Working Hours and Environment

  • Working hours: ML engineers typically work standard full-time hours, though deadlines and project demands may require additional hours.
  • Environment:
    • Work is primarily office-based or remote, depending on the company.
