Senior Data Engineer/Full-Stack Developer

About Scaylor

Scaylor helps mid-market and enterprise companies make sense of their data. Most teams past $20M ARR are stuck with fragmented systems, old databases, and hundreds of spreadsheets that never quite line up. We build the pipelines that clean, normalize, and connect that data so it can actually be used.

Our platform handles everything from parsing financial models and reports to mapping tables across legacy databases and modern APIs. The goal is simple: give companies a single source of truth they can trust.

We’re a small team of four — one backend engineer, one frontend engineer, and 2 founders. We’re looking for our fifth teammate to help us scale the engine behind it all.
