  • Set technical direction and defend architecture/design decisions
  • Run design and coding sessions; collaborate with architects and engineering team members
  • Analyze business processes and system requirements to identify technology solutions
  • Manage stakeholder expectations, trade-offs, timelines, risks, and recommendations
  • Write SQL to retrieve and write data within the enterprise data warehouse (Snowflake)
  • Resolve technical conflicts; drive consensus across teams
  • Conduct code reviews; establish coding standards and best practices, including responsible AI-generated code use
  • Troubleshoot complex application and customer issues; implement durable fixes
  • Incorporate user feedback to drive enhancements and new functionality
  • Lead planning, scheduling, implementation, and deployment activities
  • Ensure thorough testing and performance-focused debugging
  • Create and maintain technical documentation (requirements, designs, system changes, processes)

  • Optionally participate in rotating on-call support

Requirements

  • Bachelor’s degree in Computer Science, Management Information Systems, or related field, or equivalent relevant experience
  • 10+ years of professional full stack development
  • Proven ability to gather and define requirements directly with business stakeholders and deliver solutions hands-on
  • Strong hands-on coding skills in Java, Python, or .NET/C# (language agnostic; engineering depth prioritized)
  • Extensive experience building both front-end and back-end components for web-based enterprise applications
  • Demonstrated enterprise solution design and architecture experience
  • Hands-on agentic AI development experience with Claude Code, GitHub Copilot, or similar tools (beyond autocomplete)

  • Experience leading code reviews and establishing enterprise coding standards
  • Experience with testing/QA methodologies, debugging, and system analysis
  • Strong analytical problem-solving and ability to structure ambiguous business problems
