The market right now

Alion currently lists 2,032 open Backend Developer jobs in Waltham from 793 companies. 247 of them were posted or refreshed in the last seven days. 710 of the employers have posted something in the last three months, which is the pool worth watching if you are starting a search now. Every listing links straight to the employer, so you apply on their own board rather than through an intermediary.

What these roles pay

1,011 of these Backend Developer jobs in Waltham state pay directly. Across them the middle half of the market sits between $174K and $250K a year, with a median of $205K. By level, the median runs junior at $140K, middle at $170K, senior at $201K, staff at $240K, and lead at $225K. The step from junior to lead is worth about 1.6x on median pay. Figures are gross annual amounts converted to US dollars, so roles in different currencies stay comparable.

Where the work is

The largest concentrations of these roles are United States (135), France (6), Spain (6), Georgia (3), and Canada (3). 100% of the listings are fully remote, so a large part of this market is open to you regardless of where you live.
