Job description

We are looking for a highly experienced Staff Software Engineer - Backend to design, build, and scale large-scale distributed backend systems that process massive volumes of data.

Location: Remote (India), NOIDA, Bangalore. Job Type: full-time. Minimum experience: 9 years.

This role is ideal for a senior technologist who thrives in complex problem‑solving environments and enjoys working at the core of high‑impact B2B and B2C platforms. You will play a critical role in shaping backend architecture, improving system performance, and enabling data‑driven products at scale.

Key Responsibilities

• Design and develop high‑performance backend systems capable of handling large‑scale data processing and query workloads.
• Build and maintain distributed microservices using Java (or Scala/C++) with a strong focus on reliability and scalability.
• Contribute to the design and optimization of data lakes, search engines, and query platforms.
• Drive architectural decisions for fault tolerance, low latency, and high availability in distributed environments.
• Optimize data storage, indexing, and retrieval mechanisms to support analytics and real‑time use cases.
• Collaborate closely with product, data, and infrastructure teams to translate requirements into robust backend solutions.
• Review code, mentor engineers, and uphold engineering best practices across the backend team.
• Identify bottlenecks in existing systems and lead initiatives to improve performance, efficiency, and stability.
• Ensure systems are secure, observable, and production‑ready with strong monitoring and alerting practices.

What Makes You a Great Fit

• Extensive experience (9-12 years) building and scaling backend systems in production environments.
• Strong expertise in Java (with exposure to Scala or C++) and deep understanding of object‑oriented and distributed system design.
• Hands‑on experience working with large‑scale distributed systems, including data lakes, query engines, or search platforms.
• Proven ability to design systems that handle high throughput, low latency, and massive datasets.
• Solid understanding of data storage technologies, indexing strategies, and query optimization techniques.
• Strong problem‑solving mindset with the ability to debug complex system‑level issues.
• Experience mentoring engineers and influencing technical direction across teams.
• Comfortable working in fast‑paced, high‑impact environments with significant ownership and accountability.
