About This Job Family
People in this job family build the infrastructure that turns raw data into reliable, accessible information. They design pipelines, maintain data warehouses, and ensure data quality at scale. When done well, their work is invisible—analysts and data scientists just get the data they need, when they need it.
What You'll Do
ML Engineers in the data org build machine learning systems that power data products—recommendation engines, forecasting models, and automated decision systems. They bridge data science and production engineering. Success means ML models that run reliably at scale.
- • Deploy and maintain ML models in production
- • Build training and inference pipelines
- • Implement model monitoring and alerting
- • Collaborate with data scientists on productionization
- • Troubleshoot model performance issues
- • Create ML system documentation
Every responsibility is an accomplishment waiting to happen. The question is: will you own the outcome, or just do the task?
AI as an Accelerator
AI isn't a skill we call out. It's invisible in the accomplishment but easily visible in the velocity and scale of your outcomes. Here's how people in this role are accelerating their work with AI:
- → Drafting ML architectures
- → Analyzing model performance
- → Generating documentation

The Competencies That Matter
Skills fill your toolbox. Competencies are how you wield them. Three matter most at this level:
1. DATA ENGINEERING (2) Strong Data Engineering skills required at this level.
2. SOFTWARE ENGINEERING (2) You're building the fundamentals—writing clean code, understanding the codebase, and shipping features that work.
3. ANALYTICS & BI (1) Strong Analytics & BI skills required at this level.
The radar shows the full picture. These three are where you need to be undeniable.
Your Journey From Here
Going up? Your next Tour of Duty:
→ Senior ML Engineer - ML Engineering (L3) "Lead a project that improves model performance"
The L2 → L3 gap is about OWNERSHIP: • From executing tasks → owning outcomes • From writing code → designing systems • From asking questions → answering them
These are your stretch accomplishments. Start doing L3 work now. When you can prove it with accomplishments, you're ready.
Going sideways? That's valid too.
Up isn't the only direction. It's your career. You own it.
