Senior Site Reliability Engineer

At The ReWork Group, we partner with high-growth startups and forward-thinking companies to build the future. To support our client's immediate Data Science endeavors, we're on the lookout for a Senior SRE. Our client sits at the intersection of two worlds that have long operated in parallel: the incumbent financial system, with its entrenched rails, opaque pricing, and gate kept access, and the decentralized economy, where programmable money, self-custody, and on-chain transparency are rewriting the rules of ownership and trust. They're scaling from thousands to millions users and they need the infrastructure to match. As a Senior SRE, you're not inheriting a mature system and maintaining the status quo. You're building the reliability foundation from the ground up, architecting resilient infrastructure, designing proactive monitoring that catches problems before users feel them, and standing up on-call processes that actually scale with the team. The challenges are real and immediate: database optimization, async workflow infrastructure, data pipeline reliability. You'll own them. And in doing so, you'll give the engineering team something invaluable — the confidence to ship fast without breaking things. This is the kind of role where your fingerprints end up everywhere. What You'll Do: Lead incident response and establish sustainable on-call practices, including comprehensive runbooks, blameless postmortems, and systematic improvements that reduce MTTR Develop and maintain self-service observability solutions using modern monitoring tools that provide actionable insights for troubleshooting and performance optimization Create and maintain infrastructure as code (using Terraform, CloudFormation) that allows for consistent, scalable, and secure cloud environments on AWS Partner closely with feature teams to architect resilient infrastructure for critical components (databases, networking, async workflows, data pipelines) that scale seamlessly Work closely with DevX to design and implement robust CI/CD pipelines with advanced deployment strategies (blue/green, canary) that enable teams to ship confidently and rapidly Advocate for best practices early in feature design, ensuring we design with reliability in mind and future-proof our services What You'll Bring: 5+ years in SRE or DevOps — or 7+ years in software engineering with a serious infrastructure focus and the scars to prove it You've led incident response for high-availability production systems — you run tight RCAs, you drive blameless postmortems, and you leave every incident with a team that's smarter than before You've designed highly available deployment architectures across multiple targets — EC2, Fargate, and beyond — with real expertise in auto-scaling, health checks, and graceful degradation when things get hard You've implemented monitoring and observability solutions that actually get used — Datadog, Prometheus, ELK, or comparable — and you've made the case internally for why observability isn't optional Deep AWS fluency and a strong infrastructure-as-code practice — Terraform is your default, not your fallback You've built and improved CI/CD pipelines that give engineering teams the confidence to ship fast and reliably #J-18808-Ljbffr
