Principal Software Architect | .NET & Distributed Systems

Most "Architect" roles are just a one-way ticket to a life of meetings and whiteboards.

This is the exception.

We are representing a Premier FinTech Leader in the Greater Philadelphia area that has built a massive, proprietary "container" capturing the entire global payment ecosystem. They are growing with a clear vision, and they need a Principal-level leader who hasn't lost their love for the code.

The Mission:

You'll shape the high-level technical vision for a high-throughput, always-on transaction platform handling billions in volume. You won't just draw diagrams; you'll jump into proof-of-concepts, validate frameworks, and solve the "impossible" technical problems that come with massive global scale.

Why this stands out:

· Architect + Builder: Influence a global ecosystem at the 30,000-foot level, then dive in to validate the actual implementation.

· Massive Scale: Event-driven, distributed systems where performance and sub-second uptime are the only metrics that matter.

· Strategic Stability: This isn't "startup chaos." The company is highly profitable, growing steadily, and backed by heavy technical investment.

· Philly Hybrid: Real flexibility for locals who want a high-stakes role without the 5-day center-city commute.

What you bring to the table:

· The Foundation: Deep expertise in Microsoft .NET / C# and distributed system design.

· The Toolkit: Experience with high-volume messaging and caching (Kafka, Redis, Event Hubs) and both SQL/NoSQL platforms.

· The Philosophy: You live by SOLID, DDD, and Clean Architecture, but you know how to balance "architectural elegance" with "practical delivery."

· The Mindset: You prefer execution over governance. You'd rather build a framework than write a policy about one.
