Principal Software Architect, Platform Engineering

• Work with product teams to find the highest-leverage places to modernize onto the platform, and shape the future-state architecture together.
• Prototype and build. Write the proof-of-concept, the reference implementation, and the code that de-risks the hard calls.
• Pair with product teams and forward-deployed architects on their toughest problems, contributing designs and maintainable code others build on.
• Own how systems compose on the platform - the cross-cutting dependencies, sequencing, and interfaces - and keep it coherent in the code, not just the design docs.
• Own outcomes as a DRI: take on-call for what you help ship, mentor the engineers you work with, and hold reliability, observability, and performance as systems move.
• Feed what you learn on the hardest problems back into the platform, so the golden paths get better and the next team has it easier.
• Bring agents into the work where they earn it: the migration and integration they can own, and the guardrails for the parts they can't.

What we're looking for

• A builder-architect, software engineer at the core. You've re-architected large, complex systems and shipped the code to prove it, not just drawn the target state.
• AI-native. You've shipped production software with generative AI and agents, and you know where to point them so they carry the work that used to eat engineers' time.
• The judgment to take on a high-stakes modernization with a team and sequence it safely, built on deep distributed-systems, microservices, and cloud fundamentals (Azure a plus).
• You do your best work embedded with a team, close to the code and close to the people who know the domain.
• The credibility to shape architectural direction across teams as an individual contributor, earned through what you design and ship.

• Bachelor's Degree in Computer Science or related technical field AND 8+ years technical engineering experience coding in languages such as C, C++, C#, Java, JavaScript, or Python - OR equivalent experience.

Other Requirements

• Ability to meet Microsoft, customer and / or government security screening requirements are required for this role. These requirements include, but are not limited to the following specialized security screenings: Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud Background Check upon hire / transfer and every two years thereafter.

Additional or preferred qualifcations

• Master's Degree in Computer Science or related technical field AND 12+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR Bachelor's Degree in Computer Science or related technical field AND 15+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience.
• Hands-on experience using generative AI and agents to build production software.
• Experience building and operating complex systems, platforms, or cloud infrastructure at scale, including hands-on re-architectures or migrations.
• Depth in distributed systems, microservices, and cloud infrastructure, including CI/CD (Azure a plus).

Come build the platform that makes every engineer ship faster - and help define what a developer platform even is in the age of agents.
