Job summary

Nscale, the GPU cloud built for AI, seeks a Senior Developer Experience Engineer to own the delivery platform end-to-end across internal developer tooling. You will shape the GitOps, CI/CD, and release architecture that engineers rely on to reach production quickly and safely.

You will lead the internal developer portal, define deployment standards, and drive adoption of Backstage or similar tooling across multiple product teams. This role is based in the US, with on-site work in major hubs.

Qualifications

• 6-10 years in platform engineering, SRE, DevOps, or software engineering, with real ownership of CI/CD or deployment systems used by many engineering teams.
• Strong software engineering skills (Python, Go, or similar).
• Deep experience with GitHub at organization scale (Actions, self-hosted runners, rulesets, permissions and governance) and with GitOps tooling (Argo CD, Flux) on Kubernetes.
• Experience automating change management or release approval against a ticketing system, ideally Jira Service Management.
• Solid command of Kubernetes, Linux, networking, and distributed systems.
• Experience with secrets and identity in pipelines (Vault, short-lived credentials, OIDC) and with artifact and supply chain management.
• Ownership of a build and release system at scale, including build performance, cache strategy, release versioning and promotion, runner fleet capacity and cost, and artifact registry design.

Responsibilities

• Own the delivery platform end to end, from pull request to production. Set the roadmap and the direction, not just respond to what breaks or what gets requested.
• Define the paved road: golden paths, repo and workflow templates, release conventions, and deployment standards that make the safe way to ship also the easy way.
• Own the internal developer portal (Backstage or equivalent) as the front door to the paved road: the service catalog, software templates, and docs, with adoption and ownership data to show it is used.
• Set the technical direction for GitOps across Argo CD and Flux, including multi-cluster promotion, drift detection, and a clear position on when to use which.
• Own the build and release layer and its performance: build tooling, remote caching, container image builds, base images, the artifact registry, and release versioning and promotion, so builds are fast, reproducible, and cheap to run.
• Own local and episodic test environments, including LocalStack, so engineers can test against cloud APIs on a laptop or in CI before anything reaches a shared environment.
• Design and lead change management automation into Jira Service Management, working with Security, audit, and engineering leadership so that evidence, risk tiering, and approvals come from the pipeline instead of from manual tickets.
• Set the SLOs and SLIs for the delivery platform (lead time, deploy success rate, CI queue time, rollback time) and use adoption and developer feedback data to decide what to build next.
• Grow the team, not just the systems. Mentor engineers through design review, pairing, and incident debriefs, and hold the bar for quality and maintainability.
• Get in early on design reviews and architecture decisions across Engineering, so deployability, rollback, and change requirements are built in from the start.
• Lead the hardest delivery platform incidents and the root causes nobody else can crack, and turn each one into a change that keeps it from coming back.
• Influence without authority. Bring other teams onto shared tooling by earning their trust, retiring the old way, and showing the numbers.
