About the role
- We're looking for a world-class Site Reliability Engineer to ensure the reliability, performance, and scalability of our AI infrastructure platform.
- Your mission: keep our ultra-low-latency, stateful, serverless compute engine rock-solid as we serve billions of agent requests for the most sophisticated AI teams in the world.
- This role is highly technical and execution-heavy.
Responsibilities
- Collaborating closely with the founders, the infra team, and the dev team-and leveraging AI wherever it creates leverage-you will architect and operate the systems that keep Blaxel fast, resilient, and secure.
- Build and evolve our observability stack (metrics, traces, logs), ensuring we detect issues before users do.
- Define, monitor, and drive SLOs/SLIs across key system surfaces to maintain world-class reliability.
- Lead incident response with rigor: root cause analysis, post-mortems, and driving systemic fixes.
- Design and implement self-healing, automated operational systems to eliminate toil and scale ops.
- Build automation and tooling-often with AI agents-to streamline operations, debugging, capacity planning, and failure prediction.
- Own security best practices at the infrastructure layer, from sandboxed compute to network isolation.
- Partner with platform engineers to ensure reliability is designed into new features from day one.
- You want to invent new reliability systems-not just maintain existing ones.
- We want you to design new reliability systems, push the boundaries of automation, and continuously evolve the platform to meet the demands of next-generation AI workloads.
Requirements
- High-velocity execution: You have a strong bias for action and a track record of shipping reliable systems quickly with excellent judgment.
- Experience with bare-metal servers and datacenter operations (PXE/iPXE provisioning, IPMI/BMC, RAID/NVMe, SR-IOV, high-throughput networking)
- Experience with infrastructure-as-code tools such as Terraform or Pulumi
- Knowledge of service mesh or API gateway technologies
- Prior experience in high-growth or high-availability environments
Nice to have
- Serverless compute systems
- Sandboxed execution environments
- Ultra-low-latency runtime engineering
- Distributed key-value stores and databases
- Chaos engineering
- Rust, Go, or systems-level programming
- Deep generative AI infrastructure
- Experience with any of the following is a plus (not required):
Skills
- 3+ years in SRE, DevOps, or infrastructure engineering roles
- Strong proficiency in at least one programming language such as Go, Rust, or Python
- Hands-on experience with a major cloud provider (AWS, GCP)
- Solid knowledge of Linux systems, networking fundamentals, and distributed systems
- Experience with Kubernetes or similar orchestrators
- Familiarity with observability stacks (Prometheus, Grafana, ELK, Datadog)
- Strong debugging, problem-solving, and incident-management skills
- Fluent across systems, cloud, networking, and distributed computing.
- Blaxel is AWS for AI agents.
- Founders choose us when they hit the limits of general-purpose clouds.
Benefits
- You'll own our reliability posture end-to-end-observability, performance tuning, incident ops, infrastructure health, and the automation systems that keep everything running smoothly.
