• Job Type: Contract to hire
• Location: Remote working Pacific time. Must be located in Pacific or Mountain time
• Compensation: This job is expected to pay about $60 - $70 per hour plus benefits
• No Visa Sponsorship Available for this role, no C2C

What You'll Do:

• Complete a structured knowledge transfer of the forecasting platform (a VB.NET client over SQL Server with SSRS reporting) from its original developer before year-end, documenting code, data flows, integrations, and business rules as you go
• Own day-to-day support, enhancement, and reporting for the platform and its companion financial applications, working directly with the finance team that depends on them
• Conduct careful impact analysis before changes to production systems, protecting data integrity and the business processes that rely on them
• Establish modern engineering discipline across the codebase: source control, documented build and release, CI/CD, automated testing, and peer code review
• Modernize delivery toward a web-based front end, retiring legacy remote-desktop delivery
• Build and maintain integrations with the company's ERP, reporting, and forecasting layers
• Serve as a core technical voice in the successor-platform selection and, once selected, build and own the governed custom layer on top of it
• Set the standard for AI-assisted development: use modern AI tooling in your own work, and establish the practices (review, testing, security, prompt and context discipline) that make it safe and productive for the team
• Work with a business analyst partner who owns functional requirements and fit-gap decisions, so you can focus on engineering

What Gets You the Job:

Required Qualifications:

• 8+ years of professional full-stack development on the Microsoft stack, with strong C#/.NET, and the ability to read and maintain VB.NET confidently
• Deep SQL Server experience: T-SQL, stored procedures, performance tuning, and SSRS report development and support
• Modern web application experience (ASP.NET Core, Blazor, React, or comparable) building interfaces for data-intensive business workflows
• Experience designing and consuming APIs and building integrations between business systems
• Solid relational data modeling, including experience rationalizing or normalizing an existing production schema
• Hands-on experience with AI-assisted development (GitHub Copilot, Claude Code, Cursor, or similar) as part of your daily engineering workflow, with the judgment to review and test AI-generated code to production standards and the ability to define AI-assisted development best practices for a team
• Prior experience inheriting a production system from a departing developer; legacy-modernization work while keeping the system running strengthens this
• Demonstrated documentation and source-control discipline (Git); you leave systems more understandable than you found them
• Strong written and verbal communication, comfortable explaining technical trade-offs to non-technical business partners

Preferred Qualifications:

• Azure fundamentals (App Service, Azure SQL, Entra ID integrated authentication)
• ETL or data-pipeline experience (SSIS, Azure Data Factory, or similar)
• Reporting modernization experience (SSRS to Power BI or similar)
• CI/CD tooling experience (Azure DevOps, GitHub Actions, or similar)
• Exposure to AI tools for querying data (RAG patterns, Azure AI Foundry, OpenAI, or similar)
• Exposure to real estate, construction, or corporate finance domains (forecasting, entity structures, capital tracking)
• Actual VB.NET authorship experience (a bonus,
