Senior Solutions Architect

Position Overview

Arch Systems is seeking a highly technical and hands-on Senior Solutions Architect to design, modernize, and deliver secure technology solutions across our federal portfolio. The Senior Solutions Architect serves as a bridge between customer mission needs, architecture, and engineering delivery. This individual works directly with federal customers, program leadership, developers, DevSecOps engineers, cybersecurity teams, data engineers, and AI specialists to translate business and mission requirements into practical, secure, scalable solutions.

This is a hands-on technical role. The Senior Solutions Architect is expected to design architectures, develop prototypes and reference implementations, evaluate technologies, troubleshoot complex technical issues, review implementations, and, when appropriate, contribute directly to software and infrastructure development.

The ideal candidate combines strong architecture skills with enough engineering depth to help teams turn architecture into working software.

What Success Looks Like

A successful Senior Solutions Architect at Arch does more than create architecture diagrams.

They can design it, explain it, prototype it, help build it, and get it into production.

They are equally comfortable:

• Whiteboarding a solution with a federal customer.
• Designing a cloud architecture.
• Reviewing an API or data model.
• Opening an IDE and debugging a difficult problem with a developer.
• Building a prototype to validate an architectural decision.
• Reviewing a Terraform deployment or CI/CD pipeline.
• Helping a program address security or ATO issues.
• Designing an AI-enabled capability.
• Creating the technical solution for a federal proposal.
• Presenting that solution during an oral presentation.

The Senior Solutions Architect is ultimately responsible for helping ensure that the solution Arch proposes is the solution Arch can actually build and operate.
