Staff Backend Engineer (Up to $250k)

Senior / Staff Backend Engineer | $140k to $250k + $50k to $80k Equity | Remote, EST Overlap

One of the fastest-growing AI startups in the US, building an AI-native ERP platform for modern finance teams.

Founded in 2024, the business has raised more than $100m from leading venture funds and experienced technology operators. Its platform is already used by businesses ranging from $5m ARR companies through to NYSE-listed organisations.

The team is rebuilding a large, outdated software category from the ground up, automating complex accounting workflows and replacing legacy on-premise systems.

This is an intense, high-output environment. The working culture is comparable to a 996 model, with long days and regular weekend work expected. It will not suit someone looking for conventional hours or strong work-life balance.
