Senior Site Reliability Engineer -AI Infrastructure Operations

About Nscale
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.

The Role
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.

What You'll Do
• 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.

What You'll Bring
• 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 Have
• Familiarity with high-performance networking (InfiniBand, RDMA).

On-Call and Pace
A quick note on the shape of the job. This role sits close to production, so there is an on-call rotation,
and some weeks are busier than others. As a senior on the team, you help set how that rotation runs
and, more to the point, how we make it lighter over time. We share the load fairly, and we treat every
page as a signal worth acting on rather than just an interruption. The goal is to leave the systems
quieter than you found them, so each rotation asks less of the person carrying it. If that's the kind of
ownership you're drawn to, you'll do well here.

What We Offer
• 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.

Salary Range
$170,000 - $265,000 USD. Actual compensation varies with skill set, experience, and location, and the
role may be eligible for bonus and equity.
