Sr. Staff Engineer, DevOps Platform

Location:

San Jose, CA (on-site)

Reporting to the Head of the Data Pillar, the Sr. Staff Dev Ops Platform Engineer owns the internal platforms that power our data and engineering teams. In this role, you’ll improve developer productivity, reliability, scalability, and operational excellence across our infrastructure, deployment systems, observability stack, and cloud‑native services.

You will build the foundational systems — cloud infrastructure, CI/CD, observability, and our data and compute platform — that let engineers across silicon, photonics, firmware, and software move quickly and reliably. You should be comfortable owning systems end to end, from architecture through on‑call.

• Cloud infrastructure: Design, build, and operate cloud infrastructure (mostly AWS) with everything defined as code using IaC tooling.
• Build & Operate the Container Platform: Design and run Kubernetes clusters and the surrounding networking, security, and storage layers that workloads depend on.
• Automate the Path to Production: Build and own CI/CD pipelines and deployment automation that let engineers ship safely and frequently, with Git Ops‑style workflows and repeatable, auditable releases.
• Own Reliability & Security: Implement least‑privilege IAM and guardrails, define and uphold SLAs, instrument end‑to‑end observability, and lead on‑call and incident response — for both the platform and the data flowing through it.
• Drive Efficiency & Self‑Serve: Optimize cloud spend and deliver self‑service paved‑road tooling and environments that let our teams provision and ship safely with low overhead.
• Observability & reliability: Improve observability through metrics, logs, tracing, dashboards, alerts, and incident response practices.
• Data & compute platforms: Contribute and collaborate on the development of our Python‑based data and compute platforms. Data asset pipelines, HPC, ML, and large‑scale simulation.
• Leading & mentoring: Establish and champion best practices for reliability, security, cost efficiency, and infrastructure governance. Mentor engineers and raise the engineering bar through reviews, documentation, and shared standards.

• Bachelor's Degree in Computer Science, Information Systems, or a related field, or equivalent practical experience.
• Minimum of 5+ years across platform/cloud infrastructure and/or data engineering, with a track record of building and operating production cloud platforms.
• Deep hands‑on experience across core AWS services — IAM, VPC and networking, S3, EC2/ECS/EKS, Lambda, Cloud Watch, and managed databases (RDS).
• Strong proficiency with Terraform/Open Tofu — reusable modules, state management at scale, and sound code structure (Cloud Formation a plus).
• Production Kubernetes experience (EKS preferred — Helm, networking, RBAC) and experience designing CI/CD pipelines (Gitlab);
  Git Ops tooling such as ArgoCD or Flux a plus.
• Hands‑on with monitoring/observability tooling such as Datadog, Cloud Watch, Prometheus, Grafana and Pager Duty, plus experience defining SLAs and managing cost.
• Python and SQL skills, as well as experience with cloud data platforms and databases.
• A passion for building scalable, well‑documented platform and data solutions that have a measurable impact; interest in applying AI tools and modern approaches to infrastructure and data problems.
• Excellent written and oral communication skills — you can write a clear status update, design proposal, or post‑mortem that people actually read — and work effectively in a team environment.
• Strong decision‑making, technical versatility, and problem‑resolution skills. Hashi Corp (Terraform Associate) or AWS certifications are a plus.

The base salary range for this role is $150,000 - $180,000, depending on experience, skills, and qualifications.

In addition to base pay, Ayar Labs offers meaningful equity (new‑hire stock options plus an evergreen program), a 401(k) with immediate‑vesting employer match, premium medical/dental/vision coverage (100% paid for employees, 75% for dependents), twelve weeks of paid parental leave, daily lunch, and more.
