Résumé du poste

Twenty Technologies is seeking a versatile software engineer to operate on-site at a government customer site in a restricted, air‑gapped environment. The role focuses on building customer-specific features, data integrations, and production resilience for Twenty’s mission‑critical platform.

You will work across the stack, sometimes with Arlington support, and sometimes lead features directly to production. This broad role emphasizes delivery speed, reliability, and learning across the platform.

  • Strong generalist programming ability in Go, Python, or TypeScript.
  • Experience shipping backend services end-to-end: design, implementation, testing, deployment, and operation.
  • Experience debugging production systems under time pressure.
  • Operational fluency: Linux CLI, containerized environments (Docker, Docker Compose).
  • Demonstrated range: delivery beyond core specialty with support from specialists.
  • Experience in forward‑deployed/embedded customer‑facing roles in restricted environments.
  • Ability to work on-site at a government facility with travel to Arlington, VA.

Responsabilités

  • Design and build customer-specific features, extensions, and integrations.
  • Integrate and test new data sources for Twenty’s applications.
  • Deploy and operate software in air-gapped, classified environments.
