Sr. Systems Engineer II - Observability (6693) with Security Clearance

As a Sr. Systems Engineer II, you'll deploy, operate, and support our observability platform - a containerized monitoring stack (Timescale DB, Open Search, Telegraf, Promethus) running on Linux hosts in an on-premises, air-gapped environment - and to serve as a strong network troubleshooter for the broader environment. You'll keep data flowing end-to-end: from network telemetry collection, through ingestion and storage, to the dashboards stakeholders rely on.

A significant part of this role is diagnosing and resolving network problems independently, including unfamiliar issues across systems you didn't build or deploy. This is a role for someone equally comfortable reading a packet capture, debugging a systemd unit, and writing a CI pipeline. with the goal to make an impact across the federal government. We know that you can't have great technology services without amazing people.

* Skills in observability, automation, and security best practices, with experience using Grafana, Prometheus, Open Telemetry, Python, SQL/PostgreSQL, secrets management, and SSH administration at scale.
* Knowledge of networking fundamentals, including TCP/IP, DNS, HTTP/HTTPS, TLS, routing, switching, subnetting, VLANs, and firewall configuration.
