This role requires strong engineering fundamentals, deep SQL/data skills, and the ability to work autonomously, driving delivery from requirements through production release and ongoing support.
RESPONSIBILITIES

Design, build, and maintain internal applications and integrations with third-party platforms across the Microsoft technology stack.
Partner with Business and Operations stakeholders to gather requirements, document them clearly, and produce technical designs/specifications.
Write clean, maintainable, well-tested code; contribute to team standards through code reviews, patterns, and documentation.
Deliver end-to-end through the SDLC: design, development, testing coordination, release/deployment, and post-release validation.
Diagnose and resolve escalated production issues; improve reliability via monitoring, performance tuning, and root-cause remediation.
Contribute to platform modernization initiatives (e.g., upgrades, migrations, infrastructure improvements).
Manage multiple workstreams (new features, integrations, maintenance) by prioritizing effectively and communicating trade-offs.
Collaborate with engineers across the organization; participate in technical discussions to drive the best solution.
Proactively identify and drive improvements in performance, scalability, resiliency, and developer productivity.
Mentor junior developers through pairing, reviews, and technical guidance.

QUALIFICATIONS

Strong backend expertise in C#/.NET, including building and operating production services.
Advanced SQL and data skills: data modeling, analysis, and building/optimizing complex queries; experience with ETL/ELT concepts and tooling.
Strong experience with Microsoft SQL Server and Snowflake, including query design and performance optimization.
Full-stack web development experience with HTML, CSS, and JavaScript (jQuery where applicable).
Hands-on integration experience with REST and/or SOAP services; comfortable working with JSON/XML.
Experience with Azure DevOps, Git, and CI/CD pipelines.
Ability to operate independently with minimal supervision: can take ambiguous problems, propose solutions, and drive them to completion.
Strong communication skills: able to explain technical concepts and trade-offs to technical and non-technical audiences.
Experience working in an Agile/Scrum environment.
Experience using AI-assisted development tools (e.g., GitHub Copilot or similar) responsibly to accelerate delivery while maintaining quality.
High ownership and accountability for delivery quality and production outcomes.
Experience deploying and operating distributed systems on Kubernetes, OpenShift, and/or Azure.
Familiarity with Domain-Driven Design (DDD) and event-driven or service-oriented architecture patterns.
Familiarity with Excel macros and VBA.
