Principal Engineer, Catalog Infrastructure (Founding Team)

About The Role

Attachments King is an eCommerce startup in the Heavy Equipment Industry developing proprietary software that flexibly discovers compatibility between equipment and host machine components.

We’re hiring a Principal Engineer to build and operate the single source of truth for a high‑SKU construction equipment catalog : taxonomy, product ingestion, price / availability pipelines from messy non‑API sources, and the automation layer that allows us to rapidly and maintainably scale SKU count, price discovery, and data quality for a small team with lean headcount.

We believe that, over the next decade, the bulk of online purchases won’t take place on websites with static product pages – and it’s our intention to build a flexible, generative merchandising platform that drives this change for the heavy equipment industry.

This role is based in San Francisco, CA. This will be an in-office role and will extend past the standard 40 hours / week of many 9-5 jobs. We have long hours, weekend work sessions, and prioritize a results-driven culture.
