Senior Software Engineer

Procare Solutions•Atlanta, GA

8d•$107,000 - $130,000•Hybrid

About The Position

As a Senior Software Engineer, you will help build and run Procare Pay, our payments processing platform that powers credit card and ACH transactions for childcare businesses across the country. You'll design and ship services across a modern, event-driven AWS architecture — from ASP.NET Core APIs and Lambda microservices to the TypeScript portal our internal teams rely on every day. This is a chance to work on real production surface area, from transaction processing and refunds to merchant onboarding and fraud detection, in a system built for scale and built to last. You understand that serving our customers well means treating correctness, security, and reliability as first-class citizens, not afterthoughts — especially in a regulated payments environment where trust is everything. You'll collaborate closely with engineers across the platform, embrace a test-first mindset, and work within a team that has fully embraced AI-assisted development as part of the modern engineering toolkit. If you want to grow your skills at the intersection of payments, cloud architecture, and next-generation developer workflows, this role offers plenty of room to make an impact. As a senior member of the team, you'll be trusted to develop complex solutions with minimal oversight and build a deep, lasting understanding of the payments business domain. You'll mentor less-senior engineers, stay current on industry and company patterns and tools, and be a voice we look to when it's time to raise the bar on how we build.

Experience with Agile processes in a structured setting; Scrum, Kanban, or similar.
Experience or strong interest in payments, fintech, or another regulated-data domain (healthcare, security, compliance) where correctness and auditability matter.

Comfort working with CI/CD pipelines and infrastructure-as-code, whether CloudFormation, Terraform, CDK, or similar tooling.
Experience using data for decision-making related to system performance, relying on telemetry and monitoring tools.
Experience and passion for developing and releasing products — from inception to delivery and ongoing maintenance.
Openness to using AI coding tools (e.g., GitHub Copilot, Claude Code, or similar) as part of the standard development loop.
Excellent communication, documentation, and interpersonal skills.

Nice To Haves

Prior experience at a fast-paced SaaS company.
