The pathway
How you actually get there, here
How you become one varies far more by country than what one does. This is the UK route. Most people take one of these ways in; the right one depends on where you're starting from.
- 1
From AI Engineer (Mid-Level)
2-3 years as an AI EngineerSkills to master
- Independently owning end-to-end model deployments, designing robust CI/CD for ML, troubleshooting complex production issues, and providing informal mentorship.
You're ready to move on when
- Successfully deployed 3+ complex models into production without significant issues.
- Can debug and resolve P2/P3 production incidents independently.
- Has contributed to MLOps best practices or documentation.
- Is regularly sought out by junior engineers for technical advice.
- 2
From Senior Software Engineer (with ML focus)
5-7 years as a Senior Software EngineerSkills to master
- Deepening ML-specific knowledge (model lifecycle, data drift), gaining hands-on experience with MLOps platforms, and understanding the unique challenges of AI in production.
You're ready to move on when
- Has built and deployed production-grade software systems, ideally with some ML components.
- Strong grasp of distributed systems, cloud architecture, and software engineering best practices.
- Demonstrable interest and self-study in machine learning and MLOps concepts.
- Can articulate the differences between traditional software deployment and ML model deployment.
- 3
From Senior Data Scientist (with strong engineering skills)
5-8 years as a Senior Data ScientistSkills to master
- Transitioning from notebook-centric development to production-grade software engineering, focusing on scalability, reliability, and MLOps tooling rather than just model development.
You're ready to move on when
- Has built and prototyped complex ML models and understands their limitations.
- Has a strong desire to focus on the 'how' of deployment rather than just the 'what' of model building.
- Proficient in Python and comfortable with software engineering practices (testing, version control).
- Has some experience with cloud platforms and containerisation.
