Senior Software Engineer - Full Stack

Pearly is a B2B SaaS and payments company with deep product-market fit, a hyper-modern stack, and over 2,500 dental offices on the platform. We're scaling rapidly, and continuously shipping capabilities that impact millions of users. This is a hands-on Senior Software Engineer role weighted toward the backend and data — services, APIs, and the Postgres layer — with React frontend work as a secondary part of the job. You'll write production-grade TypeScript and SQL, owning features and initiatives end-to-end across our product domains, and use AI heavily in your day-to-day workflow. If you're a tenacious builder who thrives on ownership, sets the bar through your own work, and is ready to help define the playbook during the excitement of the LLM era — this is your role. HOW WE BUILD Strict TypeScript, Cloud PostgreSQL, Serverless Functions, Terraform, React, GraphQL, Docker, Bun, and GitHub Actions. Strong test coverage across unit, integration, and E2E. Each engineer works with the latest AI tools — Claude Code, Cursor, MCP, Bugbot — and we stay realistic about what LLMs can and can't do. Humans drive the specs, author collaboratively with AI, and review every layer before code hits production. WHAT YOU'LL OWN PRODUCT & PLATFORM - Build backend services, APIs, and the data layer that power all of our product domains — outreach automation, payments, reporting, and analytics — with reliability and correctness as first-class concerns in a payments-critical domain. - Own data modeling, ETL, and vendor SDK integrations across EHRs, payment processors, and external vendors. - Contribute to the React frontend and internal tooling where your work spans the full stack. CODE QUALITY - Raise the bar through your own example and through rigorous, constructive code review. - Write code and documentation that guides both human engineers and AI agents toward excellence. DEVELOPMENT LIFECYCLE - Partner with Product from ideation through production release to turn business goals int
