SentiLink supports a variety of ways to work, ranging from fully remote to in-office. We operate as a digital-first company with strong collaboration across the U.S. and India. We maintain physical offices in Austin, San Francisco, New York City, Seattle, Los Angeles, and Chicago in the U.S., and in Gurugram (Delhi) and Bengaluru in India. If you’re located near one of these offices, we would love for you to spend time in the office regularly. Some roles are hybrid or in-office by design. 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. 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
