Staff Software Engineer, Frontend Platform

Modern Health is a mental health benefits platform for employers, offering a comprehensive solution for mental well-being needs. They are seeking a Staff Frontend Engineer to lead the technical foundation for their frontend architecture, focusing on design systems, developer experience, and collaboration with backend engineers.

Responsibilities:

• Set the technical vision and long-term architectural direction for our frontend platform across web (React) and mobile (React Native)
• Design, build, and evolve shared foundations — design system, component libraries, state management patterns, routing, build tooling (Vite), and testing frameworks
• Drive developer experience improvements: CI/CD pipelines, linting, type safety, code generation, MR/PR workflows, and metrics that surface platform health
• Own and advance accessibility (WCAG) and internationalization/RTL standards across the frontend ecosystem
• Partner with backend engineers to design and evolve GraphQL APIs powered by Python services (Django, Flask), and contribute backend changes when needed to unblock platform work
• Engineer efficient and reusable systems that drive complex web and mobile applications
• Maintain HIPAA and GDPR compliance and general security through best-practice implementation
• Lead ambiguous, large, or cross-team initiatives — collaborating closely with design, product, and engineering partners to deliver delightful and consistent user experiences
• Write and maintain technical documentation, unit tests, and integration tests
• Be a thought leader in strategic engineering and tech initiatives, and lead/contribute to cross-team engineering forums
• Mentor frontend and full-stack engineers to scale your impact across the engineering department
• Provide compassionate and impactful reviews of technical project plans and code

Requirements:

• 8+ years of relevant software development experience, with a clear focus on frontend engineering
• Deep expertise in React, TypeScript, and modern frontend tooling (Vite, Webpack, or similar); experience with React Native strongly preferred
• Proven track record designing and scaling frontend platforms, design systems, or shared component libraries used by multiple product teams
• Strong working knowledge of GraphQL (schema design, client tooling) and the ability to contribute meaningfully to backend services in Python (Django/Flask) when needed
• Experience driving frontend architecture decisions — state management, performance, bundling, rendering strategies, and testing
• Strong grasp of web performance, accessibility (WCAG), and internationalization (including RTL is a plus)
• Experience improving developer experience and CI/CD for frontend codebases (linting, type checks, automated testing, MR/PR workflows, metrics)
• Excellent written and verbal communication skills, with the ability to influence across teams
• Ability to work effectively with and mentor a distributed engineering team
• Experience leading and architecting large-scale projects as a technical thought leader
• Passion for building something to improve the lives of others
• Immigration sponsorship is not available for this position. Applicants must be able to maintain work authorization for the duration of employment without employer sponsorship or employer-provided training plans or attestations (including, for example, the Form I-983 required for STEM OPT)
• Native mobile development (iOS/Android) beyond React Native
• Building or contributing to a design system at scale (Figma Code Connect, tokens, theming)
• Real-time messaging and notification flows (including push notifications)
• AI-assisted developer tooling (e.g., agentic coding tools, code generation, LLM-powered DX)
• Working with AWS or other cloud platforms
• SQL, bash, or other scripting languages to facilitate debugging or developer experience contributions
• Working at a high-growth startup, on SaaS software, or in Health Tech / HR Tech
