Senior Software Engineer ( SRE )

Responsibilities

• Design, write, and ship production-grade code to fix bugs, improve performance, and increase reliability across multiple services.
• Tackle complex coding challenges in live services - requiring solid understanding of algorithms, data structures, and system architecture.
• Identify and resolve application issues by diving deep across the stack - including backend code, database interactions, and infrastructure components - with the ability to implement code-level fixes where needed.
• Profile APIs and services under load to identify bottlenecks and implement fixes at the code, database, or configuration level.
• Design and evaluate infrastructure solutions - weighing tradeoffs in architecture, tooling choices, and system configuration - and clearly document rationale for decisions made.
• Collaborate effectively with US-based engineering teams, including availability for overlap hours in the late evening IST to support real-time coordination on incidents, design reviews, and cross-functional initiatives.
• Communicate clearly and proactively - write structured updates, flag blockers early, and synthesize technical context for both engineering and non-engineering audiences.
• Build tools, automation, and test frameworks to simulate traffic, validate behavior under stress, and prevent regressions.
• Improve observability by contributing to logs, metrics, dashboards, alerts, and distributed tracing.
• Collaborate on defining and measuring SLIs, SLOs, and SLAs to align reliability goals with business outcomes.
• Contribute to the development and maintenance of incident response runbooks and help improve operational processes to minimize downtime.
• Participate in incident response and root cause analysis and contribute to the engineering on-call rotation.
• Support cost optimization efforts.
• Research and evaluate new monitoring technologies or best practices to continuously improve system visibility and reliability.

Requirements

• 7-8+ years of software development experience, with meaningful time in backend or SRE/infrastructure-adjacent roles.
• Strong coding skills in languages such as Python, Go, or similar.
• Proven ability to write and ship production code - and debug it under real-world conditions.
• Deep understanding of PostgreSQL or similar relational databases, including performance tuning and query optimization.
• Ha

For example, our engineering team in India works primarily from our Gurugram office. Role: Are you a passionate software engineer who thrives on solving tough production problems, writing robust code, and making systems fast, reliable, and observable? We're looking for a Software Engineer to join our SRE team, where you'll work at the intersection of software and infrastructure, improving the reliability and performance of our most critical applications. This is a software engineering role at its core. You'll spend your time writing production code, profiling services, and debugging across the stack, with the leverage of knowing your work improves every service, not just one. You'll collaborate closely with backend and product teams to fix performance bottlenecks, chase down complex issues, and build tooling that supports better observability, cost-efficiency, and operational excellence. You'll also help improve our incident response processes, evolve our monitoring strategy, and contribute directly to high-impact production systems.
