Forward Deployed Site Reliability Engineer (TS/SCI Required)

Own the observability posture for the on-site deployment — dashboards, alerting thresholds, and log pipelines using the LGTM stack (Grafana, Loki, Tempo, Mimir).

Lead incident response on-site: triage, containment, coordination with Arlington, and customer communication.

Maintain and continuously improve runbooks for operational procedures and emergency response protocols.

Serve as the on-call anchor for the customer environment, with clear escalation paths to the engineering team.

Work with the customer deployment team to get Twenty's platform stood up and updated within the restricted environment.

Manage containerized services (Docker, Docker Compose) across deployment lifecycle — configuration, updates, rollbacks.

Apply and validate Terraform-based infrastructure changes within the enclave, in coordination with the DSO engineer who owns IaC policy and guardrails.

Perform capacity planning and flag scaling requirements to the Arlington team before they become incidents.

Serve as the primary technical interface between the government customer and Twenty's engineering team — translating operational requirements, constraints, and issues in both directions.

Represent the operational environment accurately in engineering discussions: what the team in Arlington can't see, you make visible.

Partner with the DevSecOps engineer on compliance, logging, and audit requirements specific to the customer environment.

Provide technical guidance and support to customer stakeholders on system behavior and troubleshooting procedures.

You own reliability outcomes, not just uptime dashboards — you define what "healthy" means and hold the system to it.

You're as comfortable writing a runbook as you are deep in a production incident with limited tooling and no safety net.

You operate well with minimal remote support — ambiguity doesn't paralyze you, and you know when to escalate versus when to solve it yourself.

You build trust naturally with external stakeholders, including government customers, and can translate complex technical situations into plain language under pressure.

You treat toil as a bug: if you're doing something manually more than twice, you automate it.

You communicate with precision — your incident reports and runbooks are read by people who weren't in the room, and they need to be right.

You understand that in a restricted environment, you are the feedback loop — and you take that responsibility seriously.

Experience with NATS or similar pub/sub messaging systems in production.

Background in cyber operations, intelligence systems, or signals environments.

AWS certifications (Solutions Architect, SysOps, or DevOps Engineer).

Must possess and be able to maintain a TS/SCI security clearance with appropriate polygraph

U.S. citizenship required

Willingness to travel occasionally for customer engagements and operational support
