Software Architect job in Atlanta

The EMR Architect is a core architect of Experity’s vision to become the indispensable operating system for on-demand healthcare.

By diagnosing the legacy WPF monolith and mapping a domain-by-domain path to the modern web stack, this role transforms a rigid, single-threaded system into modular, workflow-aligned services that clinicians can move through faster and clinics can build on. This position ensures Experity’s core clinical record isn’t just stable-it becomes the foundation the rest of the platform can modernize around.

We’re modernizing a legacy Windows/WPF-based EMR into a new web stack. This is a hands-on architecture role-you’ll spend real time in the existing codebase, not just reviewing it from above, debugging multi-threaded WPF code paths and tracing real-time data flows to build an accurate picture of what’s actually broken.

You’ll own the architecture story for this migration end to end: diagnosing what’s wrong with the current system, communicating that visually to engineers and leadership, and mapping a domain-driven path from monolith to modular web app aligned to real clinical workflows.

This role demands someone who can go deep on legacy Windows internals one day and present a migration roadmap to executives the next-thriving on ambiguity, incomplete documentation, and a codebase that predates most of the team.

Business impact

· Reduces patient-record risk and clinician downtime by replacing a fragile, single-threaded WPF core with a stable, modular architecture that can scale with clinic volume.

· Speeds care delivery by decomposing the EMR into workflow-aligned domains (vitals, exam, charting), cutting the friction clinicians hit moving between tasks in a shared screen and shared thread.

· Improves engineering velocity and lowers migration risk by producing a domain-by-domain roadmap that lets teams modernize incrementally instead of a high-risk, all-at-once rewrite., · A visual architecture diagnosis (diagrams, not docs) mapping the current WPF/.NET system’s failure points, including thread contention and real-time data flow issues.

Domain boundary mapping

· A domain boundary map splitting the EMR into workflow-aligned pieces (e.g., vitals intake, full exam, charting) instead of one monolithic screen and thread.

Migration roadmap

· A domain-by-domain migration roadmap sequencing the move from legacy WPF to the modern web stack, with near-term stabilization fixes called out separately from the long-term rebuild.

Architecture communication

· A set of before/after architecture diagrams usable at both engineer and executive review, showing tradeoffs at each migration stage.

What you’ll do

· Diagnose and visually communicate problems in the current WPF/.NET architecture (diagrams, not just docs).

· Debug and reason about Windows/WPF applications, including multi-threaded and real-time data (WebSockets, live push) code paths.

· Balance near-term performance and sustainability fixes with a long-term web-stack migration plan.

· Analyze the codebase to identify domain boundaries, and propose splitting the EMR into pieces aligned to workflow personas (e.g., nurse taking vitals vs. PA doing a full exam).

· Bachelor’s degree in one of the STEM fields or equivalent combination of education and experience.

· Hands-on experience with Windows/WPF application development and debugging.

· Hands-on C# multi-threaded debugging experience (race conditions, UI freezes, thread contention).

· Strong visual communication skills-can explain complex architecture and tradeoffs through diagrams at any audience level (engineer to exec).

· Experience with domain modeling and breaking down monolithic systems into bounded domains.

· Solid .NET fundamentals, including async/await and efficient sync-to-async call patterns.

· Experience with WebSockets or real-time data push architectures.

Nice to have

· Prior experience on an EMR, healthcare, or other high-reliability enterprise application.

· Experience leading or contributing to a legacy-to-web-stack migration.

· Solid, hands-on experience with TypeScript, Next.js, and modern web architecture.

· Experience designing for concurrent request handling from UI through to DB in large-scale systems.
