Role Overview:

Do you love building software that thrills your customers using AIDLC? Do you insist on high standards for the systems you and your teams design and build? Are you a progressive, hands-on software engineer with an architect’s mindset, an advocate of agile development practices, and a proponent of continuous improvement? Well if this is you, then join an energetic team of engineers building next generation applications for PDI! Software Engineer 4 is our senior-most engineering level and operates at the scope of a Software Architect. You will own the technical architecture and solution design for your product area as we drive to continuously increase our cloud maturity and mobility, defining how services are structured, integrated, secured, and scaled, and making the key design decisions for new and existing applications. You will lead medium and large sized projects, set technical direction and engineering standards across teams, and guide, train, and mentor engineers at all levels. You will partner with Product Management, Software Architects, and DevOps on solution feasibility, estimation, and the technical roadmap, and serve as the evangelist and custodian of our technology, architecture, and product. With the variety of environments, platforms, technologies & languages, you must be comfortable working in both Windows & Linux environments and learning a variety of programming languages.
This is a hands-on architect-level position (~60% hands-on design and coding, ~40% architecture, technical leadership, and mentoring) requiring expert proficiency in .NET Core, React, SQL Server, and cloud-native architecture on Azure, with ownership of system design, architectural decisions, and engineering quality across teams.

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.
