Physical Security Systems Integration Engineer

Kastle Systems•Falls Church, VA

About The Position

Kastle Systems is a physical access control company. The Systems Integration team connects Kastle’s platform with systems customers and partners already use, including APIs for event delivery, SCIM identity provisioning, and integrations with third-party visitor management, mobile credential, and middleware platforms. As a Junior Systems Integration Engineer, you will support the head engineer and wider team with integration support and implementation work. You will handle a defined share of tickets and projects, learn how integrations work end to end, and build toward owning smaller integrations. The role helps Product and Engineering teams receive clear, reproducible cases rather than unstructured customer reports. The position combines ticket triage, implementation assistance, data validation, API testing, documentation, SDK adoption support, and project and status tracking. You will work in the team’s sprint cycle, alternating between implementation work and operations and support. You will handle customer data in line with the team’s data practices and draft customer and partner communications for review, taking on more direct communication as you gain experience.
