Sr. Systems Engineer II — Observability (6693)

As a Sr. Systems Engineer II , you’ll deploy, operate, and support our observability platform — a containerized monitoring stack (TimescaleDB, OpenSearch, 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.

What You’Ll Do

: Deploy, configure, and maintain the monitoring stack across development and on-prem production environments. Lead network troubleshooting across the environment — isolate and resolve connectivity, latency, routing, and performance issues, often on systems and topologies you have no prior context for. Operate and troubleshoot Linux servers — services, storage, performance, logs, and security hardening.

Manage containerized workloads with Docker / Docker Compose; build and maintain images and service definitions. Manage software delivery into an air-gapped network: offline package/image mirroring, artifact transfer, and controlled update procedures. Diagnose data-flow issues across the network: DNS, routing, firewalls, TLS, load balancing, and switching/routing fabric.

Build and maintain CI/CD pipelines and infrastructure-as-code for repeatable, automated deployments. Write and maintain automation scripts (Bash, Python) for provisioning, monitoring, and routine operations. Manage time-series and search data stores (TimescaleDB/PostgreSQL, OpenSearch): backups, retention, indexing, and query performance.

Monitor system health, set up alerting, respond to incidents, and lead root-cause analysis. Maintain runbooks and documentation; participate in an on-call rotation as needed. What you’ll need to succeed: 8 years of experience Proficiency with network and system diagnostic tools such as Wireshark, tcpdump, dig, curl, traceroute, mtr, ss/netstat, and packet-level analysis.

Strong Linux administration experience (Ubuntu/Debian and RHEL), including shell scripting, systemd, package management, permissions, log analysis, and Bash automation. ), Infrastructure as Code (Terraform, Ansible), and Git-based workflows. Experience designing, deploying, and supporting on-premises, segmented, air-gapped, and disconnected environments, including local registries and package mirrors.

Skills in observability, automation, and security best practices, with experience using Grafana, Prometheus, OpenTelemetry, 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.
