Principal Federal Solution Architect

*Remote Position but ideally looking for someone in the DMV area. 

Principal Federal Solution Architect - Zero Trust, Automation & Identity

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 role is intended for practitioners who build, integrate, and operate secure access systems in real-world Federal environments.

Responsibilities

• Serve as final escalation point for the most complex Federal deployments
• Lead deep technical architecture reviews with government and integrator teams
• Mentor senior Solution Architects and engineers
• Influence product direction related to automation, integration, and operability
• Ability to work extended hours or flexible schedules as needed to meet customer needs, deadlines, and escalations
• This role may require more than 40 hours per week

Travel Requirements

• Flexibility and ability to travel to meet project and customer needs
• Travel requirements will vary depending on the project and may exceed 50 percent

Technical Depth Expectations

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 aligned with customer requirements for Appgate ZTNA
• Integrate Appgate ZTNA with third party systems and sources of trust or risk telemetry, including identity providers such as SAML, OIDC, RADIUS, LDAP, NGFWs, entitlement automation systems, SIEM, SOAR, ITSM, and others
• Provide detailed documentation and effective information handoff

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.
