Kolkata's IT industry is one of the most consistently underrated stories in Indian tech. Salt Lake's Sector V remains one of India's largest IT employment clusters, home to tens of thousands of engineers working across global delivery centres, captive IT operations, and a growing layer of product and deep tech companies. The city's lower cost of living, access to a large pool of engineering graduates from institutions across West Bengal, and decades of established IT infrastructure make it a serious location for companies that want engineering depth without Bangalore-level costs.
This list covers companies across three tiers: global IT services firms with major Kolkata delivery centres, established tech and product companies with engineering presence in the city, and emerging startups and scale-ups founded in Kolkata that are hiring. Companies with only registered addresses, sales offices, or support desks are excluded. Every entry has a confirmed technology or engineering presence in Kolkata.
If you are evaluating IT and tech roles in Kolkata specifically, this is a verified starting point, not a ranking, but a map of where the work is actually happening.
