Position Summary

The Senior Software Engineer will design, develop, test, and maintain enterprise web applications using a modern .NET Core + React stack. This role combines hands-on full-stack engineering with technical leadership, modern AI-assisted development practices, and mentorship of other engineers. The Senior Engineer will lead software design, conduct code reviews, drive technical planning, oversee quality, and provide guidance across the full Software Development Life Cycle (SDLC), while championing the team's adoption of AI, automation, and modern DevOps tooling across cloud platforms.

Essential Duties and Responsibilities

• Lead the design, development, and modernization of application modules using C# / .NET Core on the backend and React / TypeScript on the frontend, ensuring alignment with service-oriented and modular architecture principles.
• Supervise enhancements and defect resolution across existing modules, improving quality, performance, and integrations with upstream/downstream systems.
• Provide strategic technical leadership and guidance to the development team, ensuring high-quality code and sound architectural decisions.
• Mentor and coach software engineers, supporting their professional growth - including effective use of AI-assisted development tools (GitHub Copilot, Claude Code, MCP servers, custom agents and skills).
• Lead thorough design and code reviews, leveraging AI-powered review tools to maintain consistently high standards.
• Oversee estimation and delivery planning for software projects, ensuring realistic and achievable commitments.
• Lead and actively participate in daily standups, backlog refinement, sprint planning, and release planning, fostering a collaborative team environment.
• Translate complex business requirements into practical, scalable software solutions.
• Collaborate closely with the Engineering Manager, Product Owner, and Architects to analyze user needs and decide between new development versus modification of existing modules.
• Manage and execute the deployment process across Dev Stage Prod environments on cloud platforms (Azure and/or AWS), via modern CI/CD pipelines.
• Develop and maintain automated testing solutions - unit, integration, contract, and end-to-end (e.g., Playwright for UI, API contract tests for the backend) - and integrate AI-assisted test generation into the workflow.
• Lead understanding and management of data outputs from applications, ensuring effective and accurate data utilization.
• Help manage the technical infrastructure of applications - cloud compute, managed databases, identity, and SSO - ensuring stability, observability, and performance.
• Lead troubleshooting of performance and functional issues across the stack, providing fast, durable resolutions.
• Communicate timeline and scope expectations clearly and consistently to the team and to stakeholders.
• Lead efforts to identify and remediate security vulnerabilities - secure coding, dependency hygiene, secret management, and SSO-based authorization.
• Champion an AI-first engineering culture: contribute to and consume reusable Copilot agents, skills, and prompts; help shape how the team uses AI to plan, build, review, document, and ship software.
