Senior Site Reliability Engineer, NetBox Delivery

NetBox Labs is seeking a Senior Site Reliability Engineer for NetBox Delivery, a new team in our Applications group.

NetBox is a product that reaches people in a few ways: our open source community runs NetBox OSS; commercial customers use NetBox Cloud (SaaS) or NetBox Enterprise (self-managed). NetBox Delivery owns everything between a NetBox Core release and a healthy, running instance on Cloud and Enterprise. We ship the software, keep an eye on it in production, and when something breaks, we fix it at the source rather than working around it. You will be one of the first engineers on this team and help shape how it works.

In this role you will:

Own the NetBox build and release pipeline, from base images to downstream availability on Cloud and Enterprise

Build the release handoff between NetBox Core and the Cloud and Enterprise teams, so new releases reach customers quickly and predictably

Make NetBox faster and more reliable in production, from application startup to Postgres performance

Build real observability for the application and the release pipeline, including monitoring, alerting, and SLOs

Act as the escalation point for performance and reliability issues and take fixes back to NetBox Core when the cause is in the code

Strengthen supply chain security and support SOC 2 compliance for the build pipeline

Share on-call duties and lead incident response and postmortems for your area

Requirements:

5+ years in software engineering, platform engineering, or SRE, with proven experience writing robust, maintainable code

Production experience with Django and Postgres at scale, including schema design, migration risk, and query performance under real load

Strong container build skills, including base image design, Python dependency management, and supply chain security practices like vulnerability scanning and image signing

Hands-on experience with our stack or something close to it: AWS (EC2, VPC, IAM, RDS), Kubernetes and Helm, GitHub Actions, ArgoCD or FluxCD, Terraform, and Prometheus and Grafana

Hands-on experience building inside an AI-augmented development harness, including Claude Code and the workflows that make agentic tooling reliable

A track record of driving work across team boundaries, from writing the RFC to getting a cross-team migration done

Nice to haves:

Familiarity with the NetBox ecosystem or network automation

Open source contributions or project involvement

Experience working in a B2B software startup or high-growth organization

Deep experience with supply chain security tooling such as cosign, Sigstore, or SLSA

Experience operating high-throughput or performance-sensitive systems for large enterprise customers
