Site Reliability Engineer

Our Site Reliability Engineering team is growing, and we are looking for a highly experienced Staff Site Reliability Engineer to help shape the future of reliability, scalability, and performance at AlphaSense. This is a hands-on, high-impact role where you will architect core reliability platforms, lead by example in incident response, and drive cultural adoption of SRE best practices across our global engineering organization. Our mission is to engineer our platform to the reliability standards of mission-critical systems, targeting 99.99% uptime, while continuously enhancing our systems and processes. This role is key to that mission and goes beyond traditional system maintenance; it’s about pioneering the platforms, practices, and culture that enable engineering to scale effectively. You will act as a force multiplier, mentoring fellow engineers, influencing architectural decisions, and setting the technical bar for reliability across the company. Who You Are: 8+ years of experience in Site Reliability Engineering, DevOps, or a similar role, with at least 3+ of those years operating in a Senior+ SRE position Strong background in running production SaaS systems at scale. Proficiency in at least one programming/scripting language (Python, Go, or similar). Hands-on expertise with cloud platforms (AWS, GCP, or Azure) and Kubernetes. Deep understanding of networking fundamentals (TCP/IP, DNS, HTTP/S, load balancing). Experience with monitoring & alerting (Prometheus, Grafana, Datadog, ELK). Familiarity with advanced observability (OTEL, continuous profiling). Proven incident management experience, including leading high-severity incidents and postmortems. Strong troubleshooting skills across the full stack. Excellent communication and collaboration skills. What You’ll Do: Architect Reliability Paved Paths: Build frameworks and self-service tooling that let teams own the reliability of their services in a “You Build It, You Run It” culture. Lead AI-Driven Reliability: Drive our AIOps strategy — automating diagnostics, remediation, and proactive failure prevention. Champion Reliability Culture: Embed SRE practices across engineering via design reviews, production readiness, and operational standards. Incident Leadership: Act as Incident Commander during critical events, modeling operational excellence, and ensuring blameless postmortems lead to lasting improvements. Advance Observability: Deliver end-to-end monitoring, tracing, and profiling (Prometheus, Grafana, OTEL, Continuous Profiling) to optimize performance proactively. Mentor & Multiply: Elevate engineers across SRE and product teams through mentorship, technical guidance, and knowledge sharing. AlphaSense is an equal-opportunity employer.
