Software Engineer, Email & Communications Platform

We're looking for a Software Engineer II 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 and real room to grow. 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 build and ship features end-to-end, from database schema and API work through to the UI that internal teams and dealers interact with, partnering with senior engineers on architecture and design 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.

Here is more of what you'll get to do:

• Build, test, 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.)
• Contribute to modernization efforts — refactoring legacy code, migrating to modern patterns, and improving observability and testability in a production system
• Collaborate with product, senior engineers, and stakeholders to turn business requirements into working, well-built 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
• Learn from senior engineers, seek out feedback, and contribute to a culture of engineering excellence

You'll thrive in this role if you have:

• 2–4 years of professional software engineering experience
• Full-stack development — comfortable working across backend and frontend code
• C# / .NET — solid experience building APIs, services, or backend systems
• Microsoft Azure — some hands-on experience with Azure services (e.g., App Services, Functions, Service Bus, SQL, Storage), or cloud experience you're eager to deepen
• Email delivery concepts — exposure to or strong interest in high-volume email systems; familiarity with concepts like SPF/DKIM/DMARC, bounce management, or deliverability monitoring is a plus (we'll teach you the rest)
• SQL Server — solid experience writing queries and working with relational databases (exposure to PostgreSQL is a plus)
• Comfort in mature codebases — you're willing to read, understand, and improve existing code, not just build greenfield
• Solid fundamentals — API design, testing practices, CI/CD, and a growing interest in distributed systems
• React / Next.js — experience building modern frontend applications
• Digital marketing domain knowledge is a plus — campaign management, lead generation, marketing automation, or dealer/automotive marketing
• Exposure to message queue architectures and event-driven systems is a plus
• Familiarity with email service providers (SendGrid, Mailgun, SparkPost, etc.) is a plus
• Experience working in a multi-tenant SaaS environment is a plus
• Must be fluent in English and Spanish.
• Demonstrated ability to work effectively in a mixed mode (onsite, remote or hybrid) environment, including consistent use of video conferencing, collaboration tools, and proactive communication practices while maintaining a professional on-camera presence.
