Senior Software Engineer, Identity

About Us

Our mission is to be the technology backbone for strategic competition against peer adversaries. These missions – including intelligence, information operations, and special activities – are happening today and their success or failure will determine if we go to war tomorrow.

We've been on the front lines of these missions since 2019, and have grown to support a wide range of missions across all US service branches, multiple combatant commands, partner nations, and interagency stakeholders. We deploy both hardware and software products to support people on the front lines that span collection, planning / assessments, and effects.

We've grown from $3M in run-rate revenue in 2021 to $80M in run-rate revenue today. We've been profitable since 2022 and have raised $91M in venture capital funding through Series B. We're valued at $1.5B as of 2025.
