Job Summary

We are seeking a highly skilled Full-Stack Engineer to join our team and take complete ownership of features from user interface to cloud infrastructure. This is a true full-stack role where you'll be equally responsible for building React web applications, designing Node.js APIs, and architecting AWS serverless infrastructure.

This role requires strong proficiency with AI-augmented development tools (Cursor, Copilot, Claude) - you'll be expected to demonstrate this skill during the technical interview.

Note: This role focuses on web applications and backend infrastructure. Our mobile team handles Flutter development separately, and you'll collaborate with them by designing clean, well-documented APIs.

What Full-Stack Means Here

  • Frontend: Build React/Next.js web applications, dashboards, and user interfaces  
  • Backend: Design and implement Node.js serverless APIs on AWS Lambda  
  • Infrastructure: Architect and manage AWS resources using SAM and CloudFormation  
  • Privacy: Implement end-to-end encryption architecture across all layers  
  • Collaboration: Work alongside mobile team, providing well-designed APIs for consumption

 

Key Responsibilities

As a full-stack engineer, you'll own features end-to-end across the entire technology stack:

  • Build modern, responsive web applications using React/Next.js with excellent UX  
  • Design and implement RESTful APIs with Node.js/TypeScript on AWS Lambda  
  • Architect and manage AWS infrastructure (Lambda, DynamoDB, S3, SQS, CloudWatch, KMS, API Gateway, WAF)  
  • Implement privacy-first architecture with encryption across all layers  
  • Leverage Cursor/Copilot and Claude models for AI-augmented development  
  • Write comprehensive tests across the stack (Jest, React Testing Library, API testing)  
  • Own features from conception to deployment, including UI, business logic, and data layer  
  • Maintain CI/CD pipelines and deployment automation  
  • Create well-documented APIs consumed by web and mobile clients  
  • Collaborate with mobile team on API contracts and integration

  • Experience using Claude models (3.5 Sonnet, 4.x series)  
  • Prompt engineering for code generation and refactoring  
  • AI-augmented debugging and testing  
  • Demonstrated track record of AI-assisted development velocity  
  • Must be able to demonstrate AI usage live during coding interview - candidates will code with AI tools during the technical assessment
