Senior Software Engineer

Role Overview

• Lead architectural decisions for migrating a legacy single tenant .NET 8 application into an existing multitenant framework.
• Champion clean code principles and drive technical roadmaps that reduce technical debt while maintaining delivery velocity.
• Evaluate and introduce tooling, libraries, and frameworks that improve developer experience and system reliability.
• Mentor junior and mid-level engineers through pairing, design reviews, and structured knowledge-sharing sessions.
• Conduct constructive code reviews that uphold team standards and serve as teaching opportunities.
• Define and enforce coding standards, naming conventions, and architectural guidelines across the team.
• Identify systemic quality issues through review patterns and proactively propose process improvements.
• Act as a trusted technical reviewer for high-risk or cross-cutting changes before they reach production.
• Partner closely with stakeholders to translate business requirements into accurate technical estimates and clear implementation plans.
• Collaborate with data engineers on warehouse integrations and backend data pipelines, ensuring scalable and maintainable interfaces.
• Work with DevOps and platform teams to define deployment patterns and promote infrastructure-as-code practices.
• Facilitate cross-team alignment through clear written communication, architectural decision records (ADRs), and documentation.
• Apply test-driven development (TDD) as a core engineering discipline, writing unit, integration, and contract tests before implementation.
• Design and maintain test suites that give the team confidence to refactor and deploy frequently.
• Champion a shift-left testing culture by embedding quality practices into every stage of development, not just QA cycles.
• Ensure test coverage benchmarks are defined, tracked, and continuously improved.
• Lead sprint ceremonies including planning, retrospectives, and backlog grooming with clarity and accountability.
• Produce high-quality technical documentation including runbooks, API contracts, and onboarding guides.
• Surface blockers and dependencies early, communicating status and risk proactively to stakeholders.
• Contribute to a culture of psychological safety where candid, constructive feedback is the norm.

Requirements

• 5+ years of professional software development experience with a focus on .NET.
• .NET proficiency, including ASP.NET Core, Entity Framework Core, and the modern .NET runtime ecosystem.
• Demonstrated experience modernizing legacy web applications — refactoring, re-architecting, or re-platforming from older monolithic web applications to modern platform fabrics.
• Solid understanding of CI/CD pipelines, including pipeline design, automated test gating, artifact management, and deployment strategies (blue/green, canary, rolling).
• Clear understanding of single-tenancy vs. multi-tenancy architecture patterns and the trade-offs in security, isolation, scalability, and cost.
• Experience with test-driven development and a strong testing philosophy covering unit, integration, and end-to-end coverage.
• Strong written and verbal communication skills; able to write clear technical documentation and lead design discussions.
