Senior Software Engineer

SnailWorks is a vertical SaaS platform purpose-built for the direct mail and marketing industry. We provide real-time visibility into USPS-delivered campaigns by ingesting, translating, and enriching scan data at scale. Our customers rely on us for mission-critical tracking—outbound mail, inbound reply workflows, analytics dashboards, alerts, and Informed Delivery integration—all delivered through white-label portals and CRM-connected experiences. We serve political agencies, nonprofits, fundraising teams, and enterprise mailers who require precise timing and attribution. Many of these organizations lack structured visibility into delivery performance; SnailWorks solves that with a turnkey, operations-focused system designed for high-volume, time-sensitive campaigns. As we enter our next chapter, we are investing in technical maturity, platform scalability, and product velocity—and that's where you come in.

We are looking for a Senior Software Engineer to lead a lean, high-impact team responsible for feature delivery, platform scalability, and modernization of our core systems. You will balance hands-on development with technical leadership, helping SnailWorks evolve from a long-proven system into a more modular, resilient, and AI-accelerated platform.

• Scale and parallelize bulk processing jobs that handle large USPS scan ingestion workflows.
• Work closely with product and operations to shape roadmap priorities grounded in customer and partner needs.
