Cisco Systems is an American networking company founded in 1984 by Stanford computer scientists Leonard Bosack and Sandy Lerner, and headquartered in San Jose, California. It is the largest supplier of enterprise networking equipment in the world, building the routers, switches, wireless access points and optical systems that carry traffic across corporate networks, service providers and data centres, together with the software and silicon that run them. The company has diversified heavily into security, observability through Splunk, collaboration with Webex, and AI infrastructure networking, and now earns a growing share of revenue from software subscriptions rather than hardware sales.

How pay is distributed

Most employers in this selection do not publish a figure, so the range below is Alion's own estimate, derived from 67 comparable listings priced by role, level and country. Across them the middle half of the market sits between $60K and $74K a year, with a median of $62K. Figures are gross annual amounts converted to US dollars, so roles in different currencies stay comparable.

The market right now

Alion currently lists 87 open Backend Developer Salary in Sofia from 40 companies. 22 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. 8 of the 87 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.

Where the work is

The largest concentrations of these roles are Bulgaria (87), Ireland (8), Netherlands (8), Spain (6), and Greece (6). 13% of the listings are fully remote and a further 48% 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 Salary in Sofia right now are SumUp (8), SAP (7), Conga (4), Playtech (4), DXC Technology (4), and Experian (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 CI/CD (43), Kubernetes (40), AWS (38), Agile (34), SQL (33), Java (33), Python (32), and JavaScript (29). 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.
