## Description

Linchpin Software is looking for a hands-on Senior Solutions Architect to design and deliver enterprise solutions on AWS. You'll set the vision for large, multi-system solutions, then roll up your sleeves and help build them.

You'll design across a wide range of problems: enterprise services, software APIs, how systems interact and integrate, automated developer platforms, and secure cross-domain data transfers. No two problems look the same, and you'll own the architecture for all of them.

This is not a slides-and-diagrams role. You must be able to plan and lead a large solution AND write production code yourself. One day you're whiteboarding with the customer and earning their trust; the next you're pairing with an engineer, writing the proof of concept, or debugging a deployment. We need someone who does both, and knows when each one is called for.

We build software differently. Our team uses AI-assisted development tools (Claude Code, Codex, GitLab Duo) to prototype and deliver faster, and you'll help shape how we use them.

What You'll Do:

 * Architect enterprise solutions on AWS, from vision and design through production
 * Design enterprise services, software APIs, system integrations, and cross-domain data transfer solutions
 * Write code: prototypes, proofs of concept, core components, and infrastructure as code
 * Work hands-on with engineers through code reviews, pairing, and troubleshooting
 * Lead customer-facing technical engagements and turn mission needs into clear designs
 * Set technical direction on quality, security, automation, and scalability
