We're looking for a Senior Frontend Engineer to shape the user-facing experience of our wellness platform.

You'll collaborate closely with product and design to craft responsive, accessible, high-quality applications used by thousands.

At Assured Allies, frontend is where vision becomes reality. In a space as nuanced as aging and insurance, clarity, accessibility, and empathy matter. If you're excited to build products that help people live better, longer lives, not just ship features, we'd love to meet you.

• Develop and maintain high-quality, responsive frontend applications using
  React
  ,
  TypeScript
  , and modern web technologies.
• Own implementation of pixel-perfect interfaces, taking wireframes and visual designs from our design team and translating them into elegant, functional experiences.
• Ensure consistent user experience across devices and screen sizes, with a strong focus on
  responsive design
  and performance.
• Collaborate cross-functionally with product, design, and backend teams to build
  intuitive and scalable
  features.
• Take full ownership of your work - from development and testing to deployment and monitoring.
• Be a domain expert in frontend development, while also contributing to occasional
  full-stack
  tasks using
  Python
  when needed.
• Continuously improve our frontend architecture and code quality by participating in code reviews and knowledge sharing.
• Leverage modern
  AI-powered tools
  throughout the development lifecycle - from code generation and testing to workflow automation.

What we're looking for:

• 5+ years of hands-on experience
  building modern web applications
  .
• Strong expertise in
  React
  ,
  TypeScript
  ,
  HTML5
  ,
  CSS3, and JavaScrip
  t, plus a deep understanding of responsive design and cross-browser behavior.
• Deep understanding of
  responsive web design principles
  and cross-browser compatibility.
• Proven experience
  optimizing for performance and scalability,
  with a strong UX mindset and attention to detail.
• Proven, real-world experience using AI coding tools
  (e.g., Cursor, Windsurf, Claude Code, Copilot, or equivalent) as part of your production workflow (code generation, tests, refactors, automation).
• Comfortable working in a
  dynamic startup environment
  with high standards for product quality.
• Fluent in
  English
  (spoken and written).

Bonus

• Experience with
  design systems
  at scale (foundations, components, documentation).
• Hands-on experience with
  Storybook
  for component documentation, building and testing UI components in isolation, and supporting a scalable design system.
• Background in B2C, wellness/health, or accessibility standards.

Why Join Us?

• Build something that truly matters - your code will directly impact the lives of older adults, helping them live better, longer lives
• Work at the intersection of consumer-grade UX and clinically-backed wellness - where great design meets real-world outcomes
• Shape how our product
  feels
  to users, not just how it functions - you'll own meaningful parts of the experience from concept to production
• Collaborate with a kind, talented, mission-driven team that values craft, curiosity, and care in everything we build
