Site Reliability Engineer (SRE)

Core Responsibilities

Reliability & SLOs

• Implement and own SLIs and SLOs across Mithril's API layer and internal orchestration services to ensure customer commitments are met.
• Partner with Product and Platform teams to ensure new features are designed for operability, reliability, and performance from the start.
• Participate in an on-call rotation; drive root cause analysis (RCA) for production incidents and implement durable fixes to prevent recurrence.

Observability & Monitoring

• Build and maintain dashboards, alerts, and distributed tracing within Mithril's monitoring stack to provide high-granularity visibility into our multi-cloud infrastructure.
• Own the tooling that surfaces supply-side signal — GPU availability, provider health, reservation fill rates — to both engineering and operations teams.

Infrastructure as Code & Automation

• Develop and maintain Terraform/Pulumi modules and Kubernetes configurations to manage Mithril's growing multi-cloud provider footprint.
• Write clean, maintainable Python (or Go) to automate repetitive operational tasks — from provider API reconciliation to automated health checks and capacity rebalancing.

Capacity Support

• Assist in managing GPU capacity across providers, ensuring the marketplace can dynamically respond to supply fluctuations and customer demand signals.
• Surface capacity constraints and failure modes early; contribute to the tooling that enables Mithril to make fast, data-driven supply decisions.

Requirements

• 3+ years of experience in SRE, Production Engineering, or Infrastructure roles at a high-growth technology company.
• Hands-on Kubernetes experience: comfortable managing clusters, deployments, and troubleshooting production incidents in a multi-tenant environment.
• Cloud proficiency in at least one major provider (AWS, GCP, or Azure), including practical understanding of cloud networking fundamentals (VPC, DNS, load balancing, security groups).
• Coding ability: proficiency in Python or equivalent (Go, Rust, etc.) — you build tools and services, not just scripts. Willing to pick up new languages as needed.
• Linux fundamentals: strong command of Linux systems, TCP/IP networking, and security best practices.
• Disciplined troubleshooter: calm under pressure during production incidents, with a rigorous approach to RCA and long-term remediation.
• Clear communicator: able to document processes and explain technical trade-offs to engineering and non-engineering teammates.

Nice to Have

• Experience with GPU/TPU-accelerated workloads or AI/ML infrastructure.
• Exposure to multi-cloud deployments or niche/specialized cloud providers (e.g., CoreWeave, Lambda Labs, Nebius).
• Familiarity with distributed systems concepts — service discovery, circuit breakers, consensus protocols.
• Production experience with Prometheus, Grafana, or OpenTelemetry.
• Prior experience in a high-growth startup environment where infrastructure scope expands faster than headcount.

Benefits

• Health, dental, and vision coverage for you and your dependents
• 401k Plan with 4% company match
• 21 days of PTO & 14 company holidays; including 2 floating holidays

Salary Range: $170,000 - $230,000
