After a decade of divestments it now concentrates on industry, infrastructure, transport and healthcare, supplying factory automation and control systems, building and grid technology, trains and signalling, and the Teamcenter and NX design software acquired through a long run of software purchases. The Siemens Xcelerator platform ties hardware to software and digital twins, and the group retains a majority stake in the separately listed medical imaging company Siemens Healthineers.

The market right now

Alion currently lists 73 open Backend Developer jobs in Cluj-Napoca from 28 companies. 15 of them were posted or refreshed in the last seven days. 25 of the employers have posted something in the last three months, which is the pool worth watching if you are starting a search now. 1 of the 73 carries 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 is 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.

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Most employers in this selection do not publish a figure, so the range below is Alion's own estimate, derived from 47 comparable listings priced by role, level and country. Across them the middle half of the market sits between $52K and $62K a year, with a median of $57K. By level, the median runs senior at $54K and lead at $62K. 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 Romania (73), Austria (1), Bulgaria (1), Croatia (1), and Czech Republic (1). 15% of the listings are fully remote and a further 45% are hybrid, so a large part of this market is open to you regardless of where you live.

The employers with the most open Backend Developer jobs in Cluj-Napoca right now are Marsh McLennan (11), NTT DATA (9), Garmin (9), RebelDot (4), London Stock Exchange Group (4), and Mindera (4). 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 CI/CD (41), Agile (39), JavaScript (36), Kubernetes (31), Rest API (30), Azure (30), Java (29), and TypeScript (28). 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.
