You’ll collaborate with talented teammates who are passionate about healthcare innovation and committed to each other’s success.
Responsibilities:
We’re looking for a highly autonomous Senior Full Stack Engineer to own and evolve a survey application built on Ruby on Rails. This role is ideal for someone who thrives in a high-ownership environment and is excited to leverage AI as a core part of the development workflow.
You’ll be the primary technical driver of the product—designing, building, and scaling features end-to-end—while using modern AI tools to accelerate development and expand what a single engineer can accomplish.

• Own the full lifecycle of the survey application (design, development, deployment, maintenance)
• Build and maintain features using Ruby on Rails across the full stack
• Architect and deploy cloud-native solutions on AWS (ECS, CloudFormation, load balancers, etc.)
• Design scalable, reliable backend systems and responsive user experiences
• Embrace an AI-first development strategy
• Evaluate and integrate emerging technologies, including voice AI and conversational interfaces
• Monitor performance, troubleshoot issues, and continuously improve system reliability
• Establish best practices for code quality, testing, and deployment as a solo engineer
• Deep experience using AI coding tools (e.g., Augment, ChatGPT, Cursor, Claude, etc.) in daily workflows
  • Ability to guide, review, and validate AI-generated code, not just generate it
  • Strong intuition for when and how to rely on AI vs. manual implementation
  • Interest in integrating AI capabilities (e.g., voice, NLP, automation) into products
• Mindset & Ownership
  • Comfortable operating as the sole engineer on a product
  • Strong problem-solving skills and ability to make architectural decisions independently
  • Eagerness to learn new technologies quickly (especially in AI/voice space)
  • Pragmatic and product-focused—able to balance speed with quality

• Strong experience with Ruby on Rails (5+ years preferred)
• Own and improve CI/CD pipelines and deployment automation for the application
• Strong hands-on experience with PostgreSQL, including schema design, SQL query development, performance tuning, and troubleshooting
• Full stack development experience (frontend + backend)
• Hands-on experience building and deploying applications in AWS, including:
  • ECS (or similar container orchestration)
  • CloudFormation (or infrastructure-as-code equivalents)
  • Load balancers, networking, and scaling patterns
• Experience designing and maintaining production-grade systems

• Experience with voice AI platforms or conversational UX
• Experience with frontend development, especially React and NextJS
• Experience with CI/CD pipelines and DevOps best practices
• Startup or early-stage product experience

• One Team: We win together, support each other, and share credit.
• Inclusion: We respect differences and welcome every voice.
• Transparency: We’re open, honest, and clear about our goals.
• Agility: We move fast, test ideas, and learn as we go.
• Empathy: We listen, care, and anticipate others’ needs.
• Growth Mindset: We stay curious, keep learning, and aim to improve every day.
• Proactivity: We act thoughtfully, own outcomes, and bring our best selves to work.

• Remote work environment
• Health benefits paid for employees
• Flexible Paid Time Off Policy
• 11 company holidays per year
• Paid parental leave
• 401K with matching contributions
• Learning and development allowance
• A diverse, inclusive, and fun team!

We champion and nurture a culture where inclusiveness is instinctive and fuels innovation, connection, and a strong sense of “One Team”.
