## About the role

You'll be on the ground at a government customer site, serving as a generalist engineering presence for Twenty's mission-critical platform in a restricted, air-gapped environment. Twenty builds software for cyber operations, and the applications you'll extend and operate are used by operators and analysts working against hard national security problems.

## What they're looking for

- You have real range. You've shipped across more of the stack than your title suggests, and you get productive in unfamiliar systems quickly. You'd rather be effective at many things than perfect at one
- You know the difference between what you can do alone and what you should do with help, and you actively use Arlington specialists as a resource without being dependent on them for every decision
- You respond with urgency to operational issues and own resolution within your sphere. You're unafraid to call an incident when the signal warrants it
- You proactively create and update runbooks and documentation for the components you own. In an environment the rest of the team can't access, what you write down is what they know
- You understand the customer and the mission well enough to know which work has the greatest impact, and you redirect your focus when what you're doing isn't moving the needle
- You tailor your communication to your audience, whether that's a product engineer in Arlington, a DevSecOps teammate, or a non-technical customer stakeholder, and you proactively share information so the right people stay informed and aligned
