The Senior Software Engineer is a key technical contributor and team leader who designs, builds, and maintains applications across the full stack—including .

NET/C# applications, and our data services platform.

Working on an Agile team, the Senior Software Engineer consistently delivers well‑engineered, maintainable, and tested solutions on time, while championing user‑centered design, sound architecture, and engineering best practices.

• Principal Responsibilities
• Engineering Execution & Delivery
• Develop features for the compliance management platform on an Agile team, consistently delivering well-engineered, maintainable, and tested solutions within agreed-upon timeframes.
• Build and maintain efficient, reusable code across the stack: message handlers, ASP. NET Core APIs, SQL Server stored procedures and migrations, and Blazor UI.
• Support critical business logic across a suite of robust services and scalable data processing jobs.
• Diagnose production issues in distributed systems: trace requests across services, reason about dependency injection lifetimes in long-running hosted processes, understand retry and dead-letter behavior.
• Practice and promote Test-Driven Development (TDD), participate in sprint planning and code reviews, and adapt to new languages, tools, and frameworks as needed.
• System Design & Architecture
• Lead architectural discussions for mid-to-large systems, designing modular, extensible, well documented components that scale and minimize rework.
• Apply UI principles, cross-browser compatibility, and web standards; advocate for security, reliability, and operational excellence, including e-commerce security principles and current website security patches.
• Model business problems in C#. Clean domain types, well-chosen abstractions, code that reads like intent rather than plumbing.
• Strong object-oriented design instincts. SOLID is a starting point, not a religion. You know when to compose, when to inherit, when to keep things procedural.
• Solid understanding of dependency injection, including lifetimes, scope boundaries, captive dependencies, how DI behaves across long-running hosted services.
• Integrate with external services and SDKs as the business needs them. Ex. Azure Storage, Key Vault, Microsoft Graph, third-party APIs.
• Champion user-centered design processes that address real user needs.
• Web Development & User Experience
• Build and maintain scalable, reusable Razor/MVC components, layouts, and forms.
• Develop site architecture and wireframes; optimize SEO and functionality to meet web standards and major-browser compatibility.
• Analyze, test, and troubleshoot website performance and coding issues; stay current on web technologies, browsers, and mobile platforms.
• Code Review, Quality & Mentorship
• Perform detailed code reviews to uphold engineering standards and grow peers through constructive feedback; champion consistent coding standards and maintainability.
• Mentor and guide other software engineers through coaching, pairing, and knowledge sharing; take ownership of team delivery quality and unblock teammates.
• Lead by example in resilience, collaboration, and a growth mindset, and contribute to peer evaluations and growth planning.
• Cross-Functional Collaboration & Continuous Improvement
• Collaborate with the product team, designers, QA, and stakeholders to understand business requirements and to scope, estimate, and deliver features.
• Communicate user needs through storytelling and data, demonstrating how proposed designs solve those needs for internal teams and senior partners.
• Work comfortably across multiple teams and projects, including remote and local collaboration.
• Identify inefficiencies and lead small to mid-sized engineering efforts (e. g., migrations, tech debt cleanup, platform upgrades); contribute to hiring, onboarding, and engineering culture.

Education, Experience, Skills & Abilities

• Bachelor’s degree in Computer Science, Information Technology, or a related field preferred.
• 8+ years in software engineering or a related field, including 5+ years with dynamic and/or compiled languages and 5+ years in front-end web development.
• Strong understanding of distributed messaging — Azure Service Bus or similar, queue-based workers, idempotency, retry and dead-letter strategies.
• Demonstrated experience mentoring engineers, leading code reviews, contributing to architectural decisions, and working with APIs from concept to completion.
• Strong portfolio including mobile web, desktop, and app experiences; comfortable working on multiple teams and projects simultaneously.
• Proficient in C#, . NET, MVC, j Query, HTML, CSS, AJAX, Java Script, XML, and PHP.
• Very strong proficiency with relational databases, including modeling and performance optimization (My SQL, Postgre SQL, Aurora); familiarity with SQL Server preferred.
• ORM’s (Dapper, EF Core)
• Familiarity with Saa S models and cloud services, preferably AWS; Microsoft Azure a plus.
• Functional expertise with browser debugging tools and clean, maintainable coding practices.
• Believer in Lean and Agile values; strong understanding of user-centered design.
• Strong communication, adaptability, attention to detail, and a collaborative mindset; comfortable with remote and in-office engineering teams.
• Detail-oriented, self-motivated, and willing to learn new technologies.
