Few employers in this selection publish pay, so these figures are Alion estimates built from comparable listings by role, level and country. Gross annual, converted to USD.
The market right now
Alion currently lists 21 open Remote Fastify jobs from 15 companies. 1 of them was posted or refreshed in the last seven days. 11 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
Most employers in this selection do not publish a figure, so the range below is Alion's own estimate, derived from 13 comparable listings priced by role, level and country. Across them the middle half of the market sits between $126K and $206K a year, with a median of $173K. 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 (1), United Arab Emirates (1), El Salvador (1), and Morocco (1). 100% of the listings are fully remote, 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 Remote Fastify jobs right now are Clickhouse (5), Classwallet (3), AZX (1), Infinity Constellation (1), Datacor (1), and Teralco (1). 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 JavaScript (21), TypeScript (21), Fastify (21), Node JS (21), PostgreSQL (15), Kubernetes (13), Docker (12), and AWS (10). 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 Remote Fastify jobs, 2 state visa sponsorship, 1 offers a relocation package, and 6 include equity. These are filters on the list above, so you can narrow it to the ones that make a move possible for you.
