    Description

    Sr. Full Stack Engineer

    ENTER is a profitable, fast-growing AI healthcare fintech company on a mission to revolutionize Revenue Cycle Management (RCM). In the U.S., healthcare makes up nearly 20% of GDP, and providers spend 510% of their revenue just trying to collect money from insurance companies and patients. It's an outdated, painful, administrative mess.

    We're here to change that. Our mission is bold: automate 1% of GDP by eliminating the manual, inefficient workflows that plague financial operations in healthcare. We're building modern systems to replace the legacy software and armies of billing staff that have been the norm for decades.

    At ENTER, we believe better financial infrastructure means better healthcare. By using cutting-edge AI and automation, we empower healthcare providers to focus on what matters most: delivering exceptional care, not chasing payments.

    We're a fully remote, US-based team of engineers, designers, and healthcare experts. We're curious, mission-driven, and product-obsessed. If you're excited about building transformative technology in one of the biggest and most broken industries, we'd love to meet you.

    Location: Remote (US-based preferred)

    Type: Full-time

    Experience working with Redis, AWS infrastructure, and real-time APIs

    Familiarity with LLMs, AI tooling, or interest in integrating smart agent workflows

    A bias toward shipping fast, making pragmatic decisions, and iterating

    A high degree of autonomy and ownershipyou're comfortable architecting, implementing, and scaling solutions from scratch

    Bonus (but not required)

    Experience with HIPAA-compliant systems, healthcare data, or clinical workflows

    Previous work building internal tools, Chrome extensions, or productivity apps

    Familiarity with observability tools like Sentry, PostHog, or Honeycomb
