Role Description

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.

This is a hands-on engineering role with real ownership. Our platform is in an active modernization phase. You'll be working in a mature codebase that serves real production traffic while incrementally upgrading architecture, tooling, and patterns. That means you need to be comfortable holding two things at once: keeping the lights on for a system dealers depend on today, and making deliberate progress toward where the platform needs to be tomorrow.

You'll design and implement features end-to-end, from database schema and API design through to the UI that internal teams and dealers interact with, while identifying opportunities to retire technical debt and modernize along the way.

You'll tackle challenges around deliverability, throughput, sender reputation, and compliance — problems where good engineering decisions have measurable business impact. You'll collaborate closely with product, deliverability specialists, and other engineering teams. We're a remote-first team that values clear communication, pragmatic technical decisions, and shipping work that matters.

• 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

Qualifications

• 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
