## About the role

If your answer to “the two records disagree” is never overwrite, this role was built for you. As a Senior Data Platform Engineer, you’ll own the durable view of every resolved entity on the platform: the storage layer that holds what we know, where each fact came from, how confident we are in it, and how that picture has changed over time. When two sources disagree, both are kept with their evidence. When someone asks what we believed on a given date, and why, the platform can answer. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Design and build the storage layer that preserves source disagreement and history rather than resolving them away at write time
- Build the first release’s result and evidence store: saved per-person results linked to the originating record, prior results and human feedback retained separately, and configuration versions on every result
- Implement provenance and lineage across every node and edge against the platform’s evidence-record contract
- Store the versioned rule library and configuration, and record on every result the exact rule versions and ordered context supplied to any model-assisted step
- Ensure every write is traceable to its origin and every decision is reproducible
- Carry match confidence and other uncertainty forward through the platform rather than collapsing it into a single value
