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 (Bellevue), 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.

ABOUT THE OPPORTUNITY

As a Staff Infrastructure Engineer, you’ll own the technical direction and architecture of critical infrastructure that serves as the foundation of the SentiLink platform. You’ll operate as a technical leader across Infrastructure and partner closely with Engineering, Data Science, Analytics, SRE, and Security to design systems that improve developer velocity while increasing the reliability, scalability, security, and efficiency of our platform. This is a highly hands‑on role with cross-team scope and ownership. You’ll lead complex infrastructure initiatives from design through delivery, make architectural decisions across related systems, and help establish the standards and patterns used by engineering teams across SentiLink. You’ll be expected to identify systemic problems, navigate ambiguity and technical tradeoffs, and ensure complex projects maintain technical coherence as they scale across teams. The ideal candidate combines deep infrastructure expertise with strong technical judgment and the ability to influence engineers and teams without relying on formal authority.

TECHNOLOGIES

Python, Aurora PostgreSQL, AWS infrastructure (EC2, S3, RDS, Redshift, etc.), Kubernetes, Docker, Terraform, CICD, observability tooling (e.g., Datadog, Prometheus, SumoLogic), OpenSearch, and Linux

RESPONSIBILITIES

• Own the technical direction and architecture of critical infrastructure domains, establishing scalable patterns and standards across SentiLink.
• Lead complex, multi-team infrastructure initiatives from design and alignment through implementation, migration, and production operation.
• Design and evolve AWS and Kubernetes infrastructure that enables engineering teams to build, deploy, and operate systems reliably at scale.
• Establish best practices for Terraform and infrastructure as code, including reusable patterns, testing, configuration management, and drift prevention.
• Architect and improve CI/CD, developer tooling, and platform capabilities that increase engineering velocity and deployment safety.
• Drive reliability and observability across the platform through effective monitoring, alerting, SLOs, incident response, and operational practices.
• Own and evolve critical infrastructure across cloud networking, IAM, security, Kubernetes, and service mesh, partnering closely with SRE and Security.
• Improve PostgreSQL and Aurora architecture, performance, scalability, and reliability, including migrations and production troubleshooting.
• Lead technical design reviews and provide hands‑on technical guidance, code review, and mentorship across Infrastructure and adjacent teams.
• Partner with engineering leaders to identify systemic problems, navigate technical tradeoffs, and build platform-level solutions that benefit multiple teams.

REQUIREMENTS

• 8+ years of relevant software engineering, infrastructure, platform engineering, or SRE experience, including technical leadership across multiple teams or complex systems.
• Deep experience designing and operating production infrastructure in AWS, including networking, compute, storage, IAM, and highly available architectures.
• Deep hands‑on experience designing, operating, scaling, and troubleshooting Kubernetes in production.
• Deep experience with Terraform and infrastructure as code, including developing reusable patterns and standards adopted by other engineers.
• Experience architecting, scaling, and migrating business‑critical production systems with minimal downtime.
• Strong SRE and observability experience, including monitoring, alerting, incident response, root cause analysis, and reliability engineering.
