Description
ABOUT THE COMPANY
America is under sustained cyber attack. Our adversaries infiltrate our networks, steal our IP, and degrade the digital infrastructure that modern life runs on. They’ve learned—correctly—that those attacks rarely produce consequences.
Twenty was founded to change that, by making our adversaries think twice before they attack us. Our vision is American and allied primacy in cyberspace—a future where they cannot contest us, deterrence is assured, and the free world remains secure.
Founded in 2024, Twenty Technologies (www.twenty.io http://www.twenty.io) industrializes offensive cyber operations for the U.S. and its allies. Headquartered in Arlington, Virginia, Twenty has raised $138M from Accel, Caffeinated Capital, Friends & Family Capital, Point72 Ventures, General Catalyst, and In-Q-Tel.
ROLE SUMMARY
You'll be our eyes, ears, and hands on the ground at a government customer site, ensuring the reliability and performance of Twenty's mission-critical platform running in a restricted, air-gapped AWS environment. This role sits at the intersection of deep technical ownership and customer-facing engineering: you'll define how we measure reliability, lead incident response in a constrained environment, and serve as the primary technical link between what's happening on-site and the engineering team back in Arlington. You'll work closely with the DevSecOps engineer to ensure the platform operates within government security and compliance requirements, and with product engineers to translate operational reality into actionable feedback. You'll report directly to the VP of Engineering. If you thrive operating with autonomy in high-stakes environments and find satisfaction in making complex systems provably reliable, this role is for you.
WHO YOU ARE
- 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.
WHAT YOU'LL DO
RELIABILITY ENGINEERING
- Define, track, and report on SLIs and SLOs for platform services running in the customer environment.
- Use error budgets to drive reliability conversations with the Arlington engineering team, translating operational data into prioritized engineering work.
- Identify and eliminate toil: build automation for repetitive operational tasks within the constraints of the secure environment.
- Conduct post-incident reviews, own root cause analysis, and drive durable fixes in partnership with the engineering team.
OBSERVABILITY & INCIDENT RESPONSE
- 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.
DEPLOYMENT & INFRASTRUCTURE OPERATIONS
- Work with the customer deployment team to get Twenty's platform stood up and updated within t
