Software Development Engineer Backend

Juspay’s interview process typically starts with a timed online coding test focusing on data structures, algorithms, and basic system design. Successful candidates move to a technical interview where they solve coding problems in a functional programming language and discuss design of payment‑related services. The final HR round assesses cultural fit, communication skills, and career aspirations. Preparation should emphasize functional programming concepts, concurrency, and real‑world payment scenarios.

Juspay promotes a high‑energy, merit‑based environment where engineers are encouraged to experiment and own end‑to‑end features. The company offers clear growth tracks, regular learning sessions, and a balanced work‑life rhythm despite the fast‑paced product demands.
