Senior Software Engineer
Snail Works 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  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;
Snail Works 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.

Key Responsibilities

Lead and mentor a small engineering team, setting technical direction and elevating engineering practices.

Own feature delivery end‑to‑end—from discovery and architecture to implementation, testing, and release.

Improve the platform’s technical maturity through refactoring, automation, documentation, and observability.

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.

Introduce and champion the use of AI developer tools to increase velocity, consistency, and code quality.

Contribute to architectural decisions, cloud infrastructure improvements, and performance optimization.

What We’re Looking For

5+ years of professional software engineering experience.

Deep expertise in C#, ASP.NET, and related Microsoft web technologies.

Strong experience building and scaling production systems on AWS.

Proven ability to lead small teams or act as a senior individual contributor with leadership influence.

Product‑centric mindset—comfortable working directly with business stakeholders and customers.

Experience designing or maintaining high‑throughput data processing pipelines.

Strong understanding and hands‑on use of AI developer tools (Git Hub Copilot, ChatGPT, Claude models, etc.) to accelerate delivery.

Nice To Have

Experience with ETL pipelines, message queues, or bulk data orchestration.

Background in modernizing legacy systems or migrating monolithic workloads.

Knowledge of analytics tooling, workflow engines, or customer‑facing dashboards.

Why Snail works

Opportunity to influence architecture and team culture at a pivotal growth moment

Profitable, stable business with strong market fit and long‑term customers

High autonomy, minimal bureaucracy, and clear impact on mission‑critical products
