Across them the middle half of the market sits between $101K and $117K a year, with a median of $106K. By level, the median runs middle at $89K, senior at $107K, and head+ at $116K. The step from middle to head+ is worth about 1.3x on median pay. Figures are gross annual amounts converted to US dollars, so roles in different currencies stay comparable."},{"title":"The market right now","text":"Alion currently lists 83 open Backend Developer Salary in Belfast from 33 companies. 21 of them were posted or refreshed in the last seven days. 31 of the employers have posted something in the last three months, which is the pool worth watching if you are starting a search now. 3 of the 83 carry the marks of a stale or abandoned posting - open far beyond the usual time to fill, reposted, or on a board that mostly never closes a role - and are marked as likely inactive; the list can hide them. Every listing links straight to the employer, so you apply on their own board rather than through an intermediary."},{"title":"Where the work is","text":"The largest concentrations of these roles are United Kingdom (9), Ireland (1), Spain (1), and Portugal (1). 13% of the listings are fully remote and a further 53% are hybrid, so a large part of this market is open to you regardless of where you live."},{"title":"Who is hiring","text":"The employers with the most open Backend Developer Salary in Belfast right now are Citi (21), Kainos (5), Deloitte (5), Slice (4), TP ICAP Group (3), and Allstate Corporation (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."},{"title":"What employers ask for","text":"Reading across the current listings, the tools that come up most often are CI/CD (51), AWS (37), Java (35), Agile (34), Python (33), JavaScript (28), Kubernetes (26), and TypeScript (25). 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."},{"title":"Relocation, visas and equity","text":"Of the current Backend Developer Salary in Belfast, 2 include equity. These are filters on the list above, so you can narrow it to the ones that make a move possible for you."}],"faq":[{"question":"How many Backend Developer Salary in Belfast are open right now?","answer":"There are 83 open Backend Developer Salary in Belfast on Alion from 33 companies. The list was last refreshed on October 23, 2026."},{"question":"Are all of these Backend Developer Salary in Belfast still being filled?","answer":"Probably not all of them. 3 of the 83 show the marks Alion reads as a likely inactive posting: open far longer than employers usually take to fill such a role, reposted several times, or sitting on a board that rarely closes anything. They stay listed with a warning, and the list can hide them with one switch."},{"question":"What do Backend Developer Salary in Belfast pay?","answer":"The median is $106K a year, and the middle half of the market falls between $101K and $117K. Few of these employers publish a figure, so this is Alion's estimate based on 81 comparable listings."},{"question":"Are any of these roles remote?","answer":"11 of the 83 listings (13%) are fully remote, and you can filter the list down to them in one click."},{"question":"Which companies are hiring?","answer":"The most active employers right now are Citi, Kainos, Deloitte, Slice, TP ICAP Group, and Allstate Corporation.
