Sr. Software Engineer, Infrastructure

San Francisco HQ, Houston, TX, Ann Arbor, MI$140k - $200kFull-timePosted 2w ago
About the role
Senior/Staff-level infrastructure-focused software engineer responsible for building and operating MarianaOS platform infrastructure, with emphasis on self-service provisioning, observability, Kubernetes management, and cost/identity/secrets handling for on-prem and cloud environments.
Responsibilities
- Own our Kubernetes footprint end to end: the EKS cluster, the on-premises site clusters, cluster upgrades, capacity and autoscaling, ingress and DNS, and the GitOps delivery path that turns a merged commit into a running service.
- Build self-service infrastructure for other engineers, so that provisioning a service, a database, a preview environment, or a scheduled job is a documented path they run themselves so the team can deliver quickly.
- Make observability a default. Every deployed service should emit metrics, ship logs, trace requests, and carry meaningful alerts without its author's writing bespoke plumbing.
- Extend the platform to our sites, running on-premises and edge clusters that host GPU inference and plant data collection over constrained links.
- Own cloud cost as an engineering problem, with the visibility, budgets, and right-sizing to keep a growing platform from growing its bill proportionally.
- Own identity, access, and secrets management, so that scoped access is provisioned and revoked as a matter of course.
- Respond to infrastructure incidents and then remove the class of failure that caused them, including writing the runbook so the fix scales.
Qualifications
- 8-12+ years building and operating production infrastructure, with real depth in Kubernetes: you have run and upgraded clusters yourself and debugged multiple layers below the application.
- Strong software engineering fundamentals. You write code you would be comfortable having reviewed by a product engineer, and you reach for a well-designed tool or abstraction before a runbook.
- Hands-on experience with infrastructure as code (Pulumi, Terraform, or similar) and GitOps-style continuous delivery.
- A track record of building platforms other engineers adopted willingly.
- Practical observability experience with Prometheus, Grafana, and a log aggregation stack, and getting an organization to instrument its services.
- Comfort operating across a broad surface with incomplete context.
- Fluency in Python or TypeScript, and enough familiarity with AWS to make sound cost and architecture tradeoffs.
- Experience supporting ML or data-intensive workloads (GPU scheduling, distributed training, pipeline orchestration) is a strong plus.
- Experience with on-premise or edge infrastructure, industrial networks, or constrained-connectivity environments is a strong plus.
