Senior Site Reliability Engineer -AI Infrastructure Operations
About The Position
Nscale is the GPU cloud built for AI. We run high-performance, cost-efficient infrastructure for AI-native startups and global enterprises, from bare metal up through the platform services teams actually build on. Our culture runs on ownership, accountability, and speed. We move with urgency, we tell each other the truth, and everyone here stays close to the infrastructure that makes AI work. This is a senior SRE role for someone who sets the reliability bar and then pulls the rest of the team up to it. You'll own the hardest problems on the platform: the automation other engineers build on, the services that can't go down, and the design decisions that determine whether either holds up at scale. You'll still carry a pager, but the real job is making sure it fires less, for everyone, over time.
Requirements
- 6-10 years in SRE, systems engineering, or software engineering, with real ownership of production at scale in a data center or cloud environment.
- Strong software engineering skills (Python, Go, or similar); you build tools other engineers adopt, not scripts that run once and rot.
- Deep command of Linux, networking, and distributed systems, plus the judgment to know where the real failure modes hide.
- Hands-on with Kubernetes and virtualized or bare-metal environments; comfortable close to the metal, not just the cloud console.
- Experience running AI or GPU workloads, or high-performance computing (HPC); if not, the depth to get there fast.
- Reliability practices you put in place that outlasted you: SLOs, observability and alerting at scale, incident process, on-call that people can actually live with.
- A track record as the senior voice in incidents and design reviews, trusted to make the call under pressure.
- A habit of raising the people around you without being asked to.
Nice To Haves
- Familiarity with high-performance networking (InfiniBand, RDMA).
Responsibilities
- Own reliability for critical production services end to end; set the direction, not just respond to what breaks.
- Grow the team, not just the systems; mentor other SREs through design review, pairing, and incident debriefs, and hold the bar that pulls everyone up to it.
- Set the standards the rest of the team works to: the SLO framework, the incident process, and the on-call practices that keep it sustainable.
- Get in early on design reviews and architecture decisions, so reliability is built in rather than bolted on after the first outage.
- Lead the hardest incidents and the root causes nobody else can crack; turn each one into a change that keeps it from coming back.
- Build the tooling and automation that removes toil for the whole team, not just your own surface area.
Benefits
- Competitive base plus equity, reviewed every 12 months.
- Real ownership from the start, and a direct hand in how reliability works across the platform.
- Flexibility that treats you as an adult; we care that the work gets done, and we trust you to shape your day.
- medical, dental, vision, flexible paid time off, parental leave, and retirement plan participation.
