Senior Software Engineer, Email & Communications Platform - Remote

Overview

We're looking for a Senior Software Engineer to join the team that owns our email and communications platform — the system responsible for delivering millions of marketing emails on behalf of our dealer network. You'll work across the full stack, building and scaling the infrastructure that powers campaigns, transactional messages, and automated communications that directly drive revenue for our customers.

In Short

• 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

Requirements

• 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
• Familiarity with email service providers (SendGrid, Mailgun, SparkPost, etc.)
• Experience working in a multi-tenant SaaS environment

Benefits

• Opportunity to work on a modernizing platform with real impact
• Remote-first team that values clear communication
• Collaborative work environment with opportunities for mentorship
• Engagement in meaningful projects that drive revenue
