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
Data Platform Engineers build the internal platforms that make data accessible—self-serve query tools, data catalogs, and the infrastructure that lets analysts and scientists work independently. Their customers are internal data consumers. Success means data teams that move fast without waiting on engineering.
- • Build platform features that improve data accessibility
- • Implement data catalog and discovery improvements
- • Support data teams with platform adoption
- • Collaborate with data consumers on UX improvements
- • Troubleshoot platform issues independently
- • Create platform documentation and tutorials
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 platform designs
- → Analyzing user friction
- → Generating documentation

Your Journey From Here
Going up? Your next Tour of Duty:
→ Senior Data Platform Engineer - Data Platform (L3) "Lead a project that improves data accessibility"
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.
