## Description

We are hiring a Staff Software Engineer to help lead the next phase of AirPay's technical evolution.

This is a high-impact, high-autonomy role for an engineer who wants to do more than just build features. You will help define architecture, guide major technical decisions, mentor other engineers, and partner closely with leadership on the hardest and most important problems in the business.

You will work across core products, platform, payments, real-time systems, internal tooling, and AI-powered experiences. Some problems are deeply technical. Others are ambiguous and cross-functional. The common thread is leverage where the work you do should make the entire engineering organization and product platform better.

You should be excited about building in an environment where the pace is high, the problems are real, and the best answer is not always obvious.

What you'll work on

AirPay sits at the intersection of:

 * Healthcare infrastructure
 * Payments and financial workflows
 * Real-time event processing
 * Machine learning / LLM driven product experiences

You may work on things like:

 * Designing the systems that power patient payments, billing workflows, and insurance-related operations
 * Building reliable event-driven infrastructure for high-volume, low-latency workflows
 * Improving the architecture, performance, and maintainability of core platform systems
 * Integrating payment providers and building reconciliation, ledger, and transaction infrastructure
 * Bringing ML and LLM capabilities into production in ways that create real product value
 * Reducing complexity across the stack so teams can ship faster and more confidently
 * Raising the quality bar through better technical design, code review, documentation, and engineering standards

What you'll do

 * Set technical direction for major parts of the platform and influence the broader architecture roadmap
 * Lead cross-team initiatives that improve scalability, reliability, and engineering velocity
 * Make strong technical decisions in ambiguous environments, with good judgment around tradeoffs
 * Design and build critical systems end-to-end, from architecture through production
 * Partner with product, design, data, and leadership to translate business goals into technical strategy
 * Mentor senior engineers and help level up the team through hands-on collaboration
 * Improve developer experience, observability, CI/CD, and operational excellence
 * Evaluate new technologies and approaches pragmatically, including where AI can create durable advantage
 * Write clear RFCs, design docs, and technical proposals that help teams align and move faster
