Job description

Thoughtful is pioneering a new approach to automation for all healthcare providers. Our AI-powered Revenue Cycle Automation platform enables the healthcare industry to automate and improve its core business operations.

We are looking for an Exceptional Full Stack Engineer for our Core Platform Engineering team. As a Sr. Engineer, you’ll be a technical anchor across the stack – shaping everything from scalable backend services to responsive, intuitive frontends.

Your Role

• Lead End-to-End Builds: Own projects across the full development lifecycle – from greenfield prototypes to scaling out mature systems. You’ll take loosely defined problems and return well-architected, production‑ready solutions.
• Design for Clarity and Change: Build backend services and user interfaces that are modular, testable, and ready to evolve. You prioritize simplicity, knowing where abstraction helps – and where it just adds noise.
• Drive Pragmatic Scalability: Design for growth without overengineering. You’ll apply best practices in schema design, API modeling, and state management with a clear sense of tradeoffs and long‑term maintainability.
• Collaborate Closely: Partner with product, design, and other stakeholders to understand real‑world needs and shape the right technical solutions. You’ll operate autonomously but never in isolation.
• Continuously Level Up: Bring curiosity and humility. We’re a senior team that shares learnings freely and pushes each other to do our best work.

Your Qualifications

Frontend

• Deep experience building complex, interactive UIs using React, Vue, or Angular.
• Strong grasp of state management patterns and reactive paradigms (e.g., refs, signals, RxJS, or similar).
• Proficiency in TypeScript and JavaScript, with clean, maintainable component architecture.
• Familiarity with frontend performance profiling, accessibility, and design system integration.
• Comfortable working with designers and PMs to turn wireframes and mockups into polished interfaces.

Backend

• Proficiency in Python and TypeScript, with experience across modern backend frameworks (e.g., FastAPI, Next.js, Express).
• Skilled in API design, including versioning, pagination, and error modeling.
• Solid understanding of authentication and authorization protocols (OAuth, JWT, etc.).
• Experience with relational (PostgreSQL, MySQL) and NoSQL (MongoDB, DynamoDB) databases, including schema design, indexing strategies, and performance tuning.
• Familiarity with AWS and infrastructure concepts like CI/CD pipelines, containerization, and cloud deployments.
• Invested in setting up logging, monitoring, and alerting from day one.
• Builds with testability in mind – unit tests, integration tests, and end‑to‑end test frameworks.

What Sets You Apart

• You know how to ship fast without creating tech debt landmines.
• You balance product intuition with a strong technical foundation.
• You default to clarity and modularity, especially when designing for unknowns.
• You’ve worked at early‑stage startups or launched new systems from scratch.
• You value peer collaboration and open sharing of technical learnings.
• You care just as much about why you’re building something as how you build it.

Benefits

• Competitive compensation
• Equity participation: Employee Stock Options
• Health benefits: Comprehensive medical, dental, and vision insurance
• Time off: Generous leave policies and paid company holidays
• California Salary Range: $170,000—$220,000 USD
