  • Design, build, and maintain full-stack features across our email and communications platform
  • Work on systems that handle email delivery at scale — sending infrastructure, queue management, throttling, bounce handling, and deliverability optimization
  • Build and improve APIs, background services, and data pipelines in .NET
  • Develop and maintain cloud-native services in Azure (Functions, Service Bus, Cosmos DB, SQL, Blob Storage, etc.)
  • Drive modernization efforts — refactoring legacy code, migrating to modern patterns, and improving observability and testability in a production system
  • Collaborate with product and stakeholders to translate business requirements into well-architected solutions
  • Participate in code reviews, technical design discussions, and incident response
  • Balance new feature development with incremental improvements to system reliability, maintainability, and developer experience
  • Mentor junior engineers and contribute to a culture of engineering excellence
  • 5–7 years of professional software engineering experience
  • Full-stack development — comfortable owning features from backend to frontend
  • C# / .NET — strong experience building APIs, services, and backend systems
  • Microsoft Azure — hands-on experience with Azure services in production (e.g., App Services, Functions, Service Bus, SQL, Storage)
  • Email delivery at scale — experience with high-volume email systems, including familiarity with concepts like SPF/DKIM/DMARC, IP warming, bounce management, feedback loops, and deliverability monitoring
  • SQL Server — strong experience writing performant queries, designing schemas, and working with relational databases (exposure to PostgreSQL is a plus)
  • Legacy modernization experience — you've worked in mature codebases and know how to improve systems incrementally without breaking what's already working
  • Solid fundamentals — distributed systems thinking, API design, testing practices, CI/CD
  • React / Next.js — experience building modern frontend applications
  • Digital marketing domain knowledge — understanding of campaign management, lead generation, marketing automation, or dealer/automotive marketing
  • Experience with message queue architectures and event-driven systems
