About the role

The ideal candidate is a deeply experienced SRE and exceptional software engineer who thinks strategically about distributed systems, reliability, and operability at a global scale.
At the Staff level, you will act as a force multiplier-architecting resilient systems, driving engineering standards, and solving our most complex infrastructure challenges rather than relying on manual processes or localized fixes.
In this position, you'll provide overarching technical leadership across our SRE practice, bridging traditional site reliability, DevOps, and DevSecOps.

Responsibilities

Design and architect the overarching infrastructure strategy that enables consistent, repeatable, and secure deployments across SimSpace-hosted data centers, customer-provided hardware, and highly restricted air-gapped environments.
Partner with product and engineering leadership to balance feature delivery with platform stability.
Drive the infrastructure security posture at an architectural level.
Drive blameless post-mortems and engineer long-term, systemic, and architectural fixes to ensure classes of failures never repeat.
Drive advanced application packaging, templating, and configuration management strategies using Jsonnet and Grafana Tanka (alongside Kustomize).
Security & Compliance Architecture: Drive the infrastructure security posture at an architectural level.
Incident Command: Act as an Incident Commander during complex, high-severity outages. Drive blameless post-mortems and engineer long-term, systemic, and architectural fixes to ensure classes of failures never repeat.
We believe diversity of thought and experience fuels better solutions, and we're committed to building teams that reflect the communities we serve.

Requirements

You possess expert-level knowledge of Jsonnet and Grafana Tanka for managing complex, scalable Kubernetes configurations and application packaging.
GitOps & IaC Expertise: Extensive experience architecting sophisticated CI/CD pipelines and GitOps workflows using GitHub Actions, ArgoCD, and infrastructure-as-code principles at an enterprise scale.
In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States and to complete the required employment eligibility verification document form upon hire.

Skills

Language agnostic, but highly proficient in at least one modern language (e.g., Go, Python).

Compensation

$165,000 - $230,000 reflecting our confidence in your expertise and impact, with the opportunity for bonuses tied to company performance and individual contributions.
Actual compensation for the position is based on a variety of factors, including, but not limited to affordability, skills, qualifications and experience, and may vary from the range.
