Software Engineer IV

Key Responsibilities: Own the architecture and solution design for your product area, and be accountable for design decisions for new and existing applications, proactively escalating issues and seeking assistance to overcome obstacles. Define and document target-state architecture, system designs, and architecture decision records (ADRs); run design reviews and ensure implementations stay consistent with the agreed architecture. Design for non-functional requirements (scalability, availability, performance, security, and compliance such as PCI DSS) and make the trade-offs between them explicit. Define service boundaries, API contracts, integration patterns (REST, messaging and event-driven), and data models across services and third-party systems. Lead medium and large sized projects end-to-end, from architecture and design through production deployment. Set technical direction, coding standards, and engineering best practices across teams; guide, train, and mentor engineers at all levels, including through code and design reviews. Actively design, develop, and maintain critical services and enterprise applications using .NET Framework, .NET Core, and React, building reference implementations and proofs of concept. Partner with Product Management to consult on solution feasibility, high-level effort estimation, and the technical roadmap. Prepare and provide project status and risk assessments, including technical and architectural risks, to management with appropriate levels of detail to ensure programs stay on schedule. Collaborate with Software Architects and DevOps teams to evaluate tools, processes, technologies, and cloud infrastructure, including build-versus-buy decisions. Make recommendations for technology adoption and framework improvement, analyzing trends, patterns, and best practices for software, including AI-assisted development (AIDLC). Serve as the evangelist and custodian of technology, architecture, and product. Identify systemic performance, reliability, and scalability risks; drive root-cause analysis of production incidents and the architectural fixes that follow. Use a disciplined approach in an Agile environment to assist in analysis and determination of preferred solutions to technical challenges. Troubleshoot, test, and validate software issues; resolve issues with due urgency and maintain thorough documentation of all software solutions. Work with Product Owner to clarify and estimate feature work, and with QA Engineers to develop optimal product test plans and resolve issues found during release stabilization. Own the technical debt roadmap: identify, prioritize, and drive modernization and improvements across teams.

Qualifications: Bachelor’s degree in computer science or related field plus 9+ years’ experience designing, developing, and maintaining software applications in a software product development environment, OR equivalent experience. 4+ years of experience serving as a technical team lead or in an architecture role. Proven track record of designing and delivering distributed, cloud-native systems end-to-end, including microservices, event-driven architecture, and API design. Expert in: .NET Framework, .Net/.NET Core, C#, SQL, ASP.NET, ASP.NET Core, MVC, REST API, React. Strong knowledge of architecture and design principles: design patterns, domain-driven design, SOLID, scalability, resiliency patterns, caching, and messaging (for example, Azure Service Bus). Strong experience with SQL Server and NoSQL data stores (for example, Cosmos DB): data modeling, stored procedures, and query performance tuning. Deep knowledge of C# development including: multi-threading, memory management, async programming, microservices, dependency injection. 3+ years of experience designing and running cloud native applications on Azure (or AWS/GCP): Infrastructure as a Service, Docker/containers, CI/CD, and observability. Understanding of application security and compliance (OWASP, PCI DSS), with experience i
