Software Engineer, Backend

Candidates typically go through three rounds: a coding and system design interview, a technical deep dive focused on data platform architecture, and an HR interview. The coding round tests data structures, algorithms, and language proficiency, while the system design round evaluates scalability, reliability, and cost‑efficiency considerations. Interviewers often ask about past projects involving big data, observability, or AI tooling. Preparation should include coding practice, system design mock interviews, and reviewing recent data platform trends.

The platform promotes a collaborative environment where engineers are encouraged to experiment and innovate. Continuous learning and cross‑functional teamwork are core values, and the company supports a healthy work‑life balance with flexible schedules and remote options.

Bachelor’s (B.E./B.Tech.) or Master’s (M.E./M.Tech.) or Ph.D. in Computer Science or equivalent. Minimum 3+ years of professional experience in software engineering. Proficiency in at least one of Go, Java, or Python. Experience with AI coding tools and big‑data infrastructure is preferred. No backlog policy applies.

Round 1: Technical interview – coding and system design (30‑45 min) → Round 2: Technical deep dive – data platform architecture and problem solving (45‑60 min) → Round 3: HR interview – culture fit and career goals (30 min)
