Based only on the listings that state pay. Gross annual amounts, converted to USD so roles in different currencies stay comparable.
The market right now
Alion currently lists 193 open Vitest jobs from 135 companies. 23 of them were posted or refreshed in the last seven days. 116 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
59 of these Vitest jobs state pay directly. Across them the middle half of the market sits between $77K and $199K a year, with a median of $140K. 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 Poland (17), Germany (10), Czech Republic (9), Italy (5), and United States (4). 32% of the listings are fully remote and a further 26% are hybrid, so a large part of this market is open to you regardless of where you live.
Who is hiring
The employers with the most open Vitest jobs right now are Apify Technologies s.r.o. (7), About You (6), Arena (5), SQLI (4), Addepar (3), and General Dynamics Information Technology (3). Each company page on Alion carries its size, funding stage, tech stack and every other position it has open, so you can judge the employer before you spend an evening on the application.
What employers ask for
Reading across the current listings, the tools that come up most often are Vitest (193), JavaScript (184), TypeScript (184), React.js (158), CI/CD (119), Playwright (118), Jest (87), and GitHub (83). The counts are how many of these openings name each one, which is a better guide to what is actually being hired for than a generic skills list.
Relocation, visas and equity
Of the current Vitest jobs, 13 state visa sponsorship, 8 offer a relocation package, and 26 include equity. These are filters on the list above, so you can narrow it to the ones that make a move possible for you.
