Lead Application & Product Architect, Tax, .NET/AI

Role Overview

• Define and drive product and platform architecture for Tax services, with a focus on event driven and workflow orchestrated designs (Temporal) and streaming (Confluent Kafka).
• Lead decisions on patterns, integration contracts, data models, resiliency, and observability.
• Review and guide .NET application code and solution designs (.NET 6/8, ASP.NET Core), elevating code quality, testability, security posture, and performance.
• Partner with teams on upgrade roadmaps and dependency hygiene.
• Own high risk technical spikes and POCs; rapidly validate approaches using VS Code and GitHub Copilot to accelerate engineering feedback loops.
• Provide clear decision records (ADRs) and architectural documentation, and lead design reviews per Architecture CoE policies, champion reuse where practical.
• Lead migration/modernization efforts (modularization, API first, messaging, caching strategies), aligning with the TAA modernization milestones (Temporal orchestration, Kafka onboarding) and platform guardrails.
• Collaborate with Platform Engineering to onboard domains to Confluent Cloud; set partitioning, schema strategy, consumer group patterns, and SLAs.
• Guide performance testing and tuning practices.
• Ensure threat modeling and Security Review / SRTM artifacts are produced and signed off; partner with Security Champions and AppSec CoE to meet standards.
• Translate complex design tradeoffs into concise executive communication and product decisioning.
• Coach squads and tech leads; elevate design maturity across teams via templates, patterns, and learning sessions.

Requirements

• Bachelor's degree in Computer Science, or equivalent work experience.
• 10+ years in software engineering with 5+ years in architecture for SaaS products;
• Strong hands-on depth with .NET (C#, ASP.NET Core, API design), code review, refactoring, and performance profiling.
• Proven delivery of modernization programs (monolith to modular/microservices, event driven patterns, API first, cloud native).
• Practical experience with Kafka (Confluent preferred): topics, partitions, consumer groups, schema registry, connectors, and end to end performance testing/tuning.
• Practical experience with Temporal (or equivalent workflow engines) for long running orchestrations and reliability patterns.
• Fluency with VS Code and GitHub Copilot to accelerate POCs, scaffolding, and code reviews.
• Expertise in architecture qualities/NFRs (availability, scalability, security, resilience, cost) and observability.
• Excellent written & verbal communication—able to dive deep with engineers and rise above for leadership alignment.
