Full Job Posting

Key Responsibilities

  • Core platform development - maintaining and enhancing our flagship product's core business logic, web applications, and databases, including performance tuning and production fixes across the full stack.
  • Next-generation platform development - designing and building features end-to-end on our modern platform, spanning APIs, modern web front ends, and cloud-based infrastructure.
  • Agentic development with Claude Code - using Claude Code as your primary development environment, and building and improving the CLAUDE.md files, skills, agents and workflows the rest of the team relies on.
  • Architecture and technical direction - contributing to design decisions across core and next-generation platforms, reviewing code and setting the standard for quality, including the review of AI-generated code.
  • Mentorship - raising the level of the team through code review, pairing and showing others what AI-first development looks like in practice.

Required Qualifications

  • 8+ years of professional software development experience, with a track record of senior-level ownership: taking features from ambiguous request through design, build, release and support.
  • Deep C#/.NET experience across both generations of the stack:.NET Framework with ASP.NET MVC, and modern.NET / ASP.NET Core.
  • Professional C++ experience and the ability to work productively in a large, long-lived production C++ codebase.
  • Strong SQL Server skills - schema design, T-SQL, stored procedures, query and index performance tuning on production databases.
  • Production React and TypeScript experience building real applications.
  • Full, daily use of Claude Code as your primary development tool. You should be able to show us how you work: CLAUDE.md files, custom skills or commands, subagents, MCP servers, hooks, parallel sessions or worktrees, and how you verify what the agents produce.
  • Experience building agentic workflows beyond your own desk - Claude Code in CI/CD pipelines, automated review, spec-driven or multi-agent development.

Nice to Have

  • Experience building AI features into products - LLM integrations, tool use, retrieval or agent-based functionality on top of application data.
  • Multi-tenant SaaS experience, including tenant isolation and enterprise customer requirements.
  • Kubernetes and Docker experience.
  • IBM Cloud experience, or strong experience with Azure or AWS.
  • Background in fleet, transportation, telematics, GPS, routing or logistics software.
  • Experience supporting both self-hosted and cloud-hosted deployments of the same product.

What We Offer

  • Competitive salary and performance-based bonuses.
  • Full health and wellness benefits.
  • Flexible work hours and remote-friendly setup.
  • Full access to Claude Code and modern AI tooling, and the autonomy to shape how our team uses it.
  • A collaborative team culture focused on modernizing software that drivers, parents and school districts rely on every day.
