About The Position

We’re hiring a .NET Architect to lead architecture and modernization of mission-critical platforms. This is a hands-on role for someone who has built distributed, event-driven systems at scale and can drive AI-enabled engineering across design, delivery, and operations. This is not a “PowerPoint architect” role — you will code, review, prototype, and lead execution.

Requirements

12+ years of engineering experience, including 3+ years of true architecture ownership
Proven production experience building distributed, event-driven systems
Deep expertise in C#, .NET (Core + Framework)
Strong AI adoption mindset — you actively use AI tools to improve delivery velocity and quality
Strong hands-on experience with messaging/eventing patterns (queues/streams, retries, idempotency, DLQs)
Demonstrated success modernizing legacy enterprise platforms through incremental migration strategies
Expert-level performance engineering (memory/threading, API + database tuning, profiling tools)
Azure architecture experience (AKS, Functions, App Services, APIM, Storage preferred

Responsibilities

Architecture ownership for modern .NET platforms (C#, .NET 6/7/8, ASP.NET Core)
Design and evolution of distributed, event-driven systems (messaging, sagas, resiliency, eventual consistency)
Legacy modernization strategy + execution (monolith → modular/microservices via safe, incremental migration)
Performance and scalability engineering (profiling, tuning, latency/throughput optimization, load testing)
AI-first engineering (scale what’s already working): o Strengthen and standardize existing AI-assisted delivery across teams (coding, review, test creation, analysis) o Embed AI into modernization workflows to reduce cycle time, defects, and technical debt o Accelerate quality and operations through AI-enabled automation (impact analysis, regression optimization, faster RCA) o Improve observability using AI-supported insights (signal detection, log/trace summarization, incident learning loops)
Cloud architecture on Azure (preferred) with strong reliability, security, and cost discipline
Engineering guardrails: architecture patterns, reference designs, quality gates, and secure-by-design principles
