Site Reliability Engineer

About Blitzy Blitzy is a Cambridge, MA based AI software development platform on a mission to revolutionize the software development life cycle by autonomously building custom software to unlock the next industrial revolution. We're transforming how enterprises build software, turning enterprise requirements into production-ready code with an agentic software development platform that can autonomously execute 80% of the quantum of software development work. We're backed by multiple tier 1 investors, and have proven success as founders of previous start-ups. Location: Remote (U.S.), with occasional travel for key customer workshops Compensation: $140,000 - $170,000 base salary (bonus + equity commensurate with experience) Eligibility: U.S. citizenship required (customer badging requirement); no security clearance required The Role As a Site Reliability Engineer on Blitzy's Public Sector team, you will be the backbone of our platform's reliability and operational excellence for a dedicated enterprise customer opportunity in a highly regulated industry. You'll deploy and operate Blitzy's self-hosted platform within the customer's secure cloud environment, serving as Blitzy's embedded engineer on the account. You'll work at the intersection of software engineering, infrastructure, and customer success, ensuring our AI-powered development platform remains highly available and performant in one of the most demanding security environments in enterprise software. This is a high-impact, hands-on role for an engineer who thrives in a fast-moving environment and takes deep ownership of the systems they operate. What Success Looks Like In 30 days: You have a deep understanding of Blitzy's self-hosted deployment architecture, have begun customer onboarding, and are actively supporting deployment planning alongside customer infrastructure teams. In 90 days: You are operating inside the customer environment, have stood up and hardened the deployment, and have established monitoring, alerting, and incident response workflows that meet the customer's security requirements. In 6 months: The platform is running reliably at scale with defined SLOs and validated capacity headroom, and you are the trusted technical voice for the customer's infrastructure, security, and platform teams. Areas of Ownership Deploy, operate, and maintain Blitzy's self-hosted platform within a customer-controlled, secure cloud environment. Own the Kubernetes-based deployment: releases, upgrades, capacity planning, and performance benchmarking for compute-intensive AI workloads. Design and maintain observability — logging, metrics, tracing, and alerting — that operates fully within the customer's security boundary. Serve as Blitzy's on-account technical presence: partner with customer infrastructure, security, and governance teams on provisioning, reviews, documentation, and operational escalations. Handle sensitive customer data in accordance with customer security requirements; champion security best practices across the deployment. Feed lessons learned back into Blitzy's product and infrastructure roadmap to strengthen our self-hosted offering for future public sector customers. Required Experience U.S. citizenship (customer badging requirement) and ability to complete a customer background/badging process. 3+ years of experience in Site Reliability Engineering, DevOps, or Infrastructure Engineering roles. Strong proficiency in Kubernetes and container orchestration; hands-on experience deploying software into customer-controlled or restricted environments. Experience operating in isolated, restricted, or otherwise highly regulated network environments (defense, government, financial services, or similar). Hands-on experience with infrastructure-as-code tools (Terraform, Pulumi, or equivalent) and at least one major cloud platform. Deep expertise in observability tooling, incident management, and on-call practices. Strong scripting and automation skills (Python, Go, Bash, or similar). Excellent communication skills — you will work directly with customer engineering, security, and governance stakeholders and represent Blitzy on the account. What Makes You Stand Out Experience deploying or operating software in government-accredited or similarly certified cloud environments. Familiarity with handling sensitive data and security frameworks common to regulated industries. Experience supporting AI/ML workloads or their supporting infrastructure. Prior forward-deployed, residency, or embedded-engineer experience at an enterprise customer site. Prior experience in a high-growth startup environment where you wore multiple hats. What Makes This Role Different You won't be maintaining legacy systems or fighting fires in a sprawling monolith. You'll be a founding reliability engineer for Blitzy's public sector business — operating a greenfield deployment of an AI platform that is redefining how the world creates software, inside one of the most security-conscious enterprises in the country. Your work directly shapes the playbook for the government and defense customers that follow. You'll have direct influence over architectural decisions, work side-by-side with world-class engineers, and see the tangible impact of your work from day one.
