Software Engineer - Full Stack

About the role

About the Role

As a Software Engineer at K Health, you are the champion of technical excellence for a high-stakes portfolio of clinical AI and a suite of products that serve the patients and the physicians. We don't just build apps; we build, and operate modern, AI-powered, 24/7 virtual clinics for the nation’s largest health systems.

In this role, your mission is to help build a product ecosystem where reliability, privacy, and performance are non-negotiable. You will develop reusable components and resilient architectures that exude trust, ensuring that every patient interaction is seamless and every clinical data point is secure. You will be a "multiplier," creating the foundational frameworks that allow us to deploy 5-star experiences across a portfolio of partners without sacrificing the quality our users depend on.

This role requires onsite presence in our New York City office 4 days a week and does not provide immigration support.

What you will do

- Full-Stack: Support the end-to-end lifecycle of products and features, from multi-platform clients, to the Kotlin/JVM-based backend services that power them.

- Quality as a Feature: Enforce standards for high-stakes engineering—ensuring that performance, accessibility, and data privacy are baked into every feature

- Platform Innovation: Proactively modernize our systems to leverage agentic AI tools that improve developer productivity and team efficiency.

- Technical Stewardship: Act as a stabilizing force in complex technical situations, bringing clarity to ambiguous requirements and making informed decisions that mitigate risk.

- Mentor & Multiply: Level up the engineering organization by fostering an ownership mindset and modeling how to move fast while maintaining clinical-grade quality.

What we are looking for

- Established Expertise: 3-5+ years of professional software engineering experience, with a deep focus on building robust, customer-facing products from front-to-back.

- Full Stack Fluency: Strong professional experience in front-to-back-end development using Node/Typescript with a JVM language (Kotlin or Java) as a major plus.

- Middle Layer Proficiency: You understand how to build resilient APIs that support critical workflows on any user-facing platform. We leverage GraphQL and Typescript heavily in the middle layers.

- Tasteful User Experience: You develop with the customer in mind, and prioritize their experience across the functional and non-functional considerations that shape the overall experience across Web and for Mobile platforms.

- AI-First Mindset: Proficiency with modern agentic development tools (i.e., Claude Code), using them effectively across platforms to deliver high-quality code quickly and reliably.

- Repeatable Patterns Mentality: Experience building reusable frameworks, white-label solutions, or multi-tenant architectures where code quality directly impacts multiple products.
