About The Position

The Senior Solutions Architect is the senior technical authority responsible for the design, integration, automation, and operational success of AppGate's Zero Trust Network Access (ZTNA) platform across U.S. Federal and DoD environments.
This role requires deep, hands-on engineering expertise, not abstract or presentation-level knowledge. The successful candidate must be capable of operating systems, writing and reviewing code, debugging live integrations, and troubleshooting failures at the protocol, OS, and application level. This is a role for practitioners who build, integrate, and operate secure access systems in real-world Federal environments.
Technical Depth Expectations (Applies to All Areas Below)
For every domain listed, candidates are expected to demonstrate operational competence, including the ability to:
Configure and operate systems directly
Debug failures using logs, shell access, packet captures, and code inspection
Write and modify scripts or automation to solve real problems
Explain system behavior based on implementation, not abstraction
Design and Architect systems that align with customer requirements for Appgate ZTNA
Integrate Appgate ZTNA with other 3rd party systems and sources of trust or risk telemetry including Identity Providers (SAML, OIFC, RADIUS, LDAP(s)), NGFWs, Entitlement Automation systems, SIEM/SOAR, ITSM, and many others.
Detailed documentation and information hand-off skills are also required
This role requires engineers who actively operate systems, write scripts, debug APIs, and analyze packet captures. Candidates whose experience is limited to diagrams, presentations, or vendor marketing materials will not be successful.
