Job description

We’re looking for a full‑stack engineer who thrives at the intersection of product, architecture, and data. This role is for someone who enjoys owning systems end‑to‑end — from the UI layer to backend services, from API design to database performance tuning. If you’re energized by solving complex technical problems and building scalable digital experiences, you’ll feel right at home here.

What You’ll Bring

• 4+ years Strong hands‑on experience with React, NodeJS, and Python
• Ability to design and build RESTful APIs and microservices
• Familiarity with UI/UX principles and modern front‑end patterns
• Experience with MongoDB or any modern database (SQL or NoSQL)
• Comfort working across the full stack: frontend, backend, data, and integrations
• Solid understanding of Git, branching strategies, and code review best practices
• Experience with unit testing, TDD, and automated test frameworks
• Ability to break down complex problems and communicate solutions clearly

What You’ll Own

• Lead the technical design across the entire stack — frontend, backend, APIs, data models, and system integrations
• Ensure the platform is built for scalability, performance, and long‑term maintainability

Frontend Engineering

• Build responsive, high‑performance interfaces using React
• Optimize rendering, bundling, caching, and client‑side performance
• Collaborate with designers to translate UX concepts into production‑ready components
• Develop backend services in NodeJS and Python
• Build synchronous and asynchronous Python APIs using Flask and FastAPI
• Implement RESTful services, authentication flows, and integration endpoints
• Improve and refactor existing APIs for speed, reliability, and clarity

Data Layer & Database Ownership

• Configure, maintain, and optimize MongoDB instances
• Ensure high availability, indexing strategy, and query performance
• Work with multi‑layered data sets and design efficient data flows

Quality, Testing & Reliability

• Write clean, testable code with strong unit test coverage
• Use TDD practices to ensure reliability and reduce regressions
• Validate API behavior, interpret test results, and troubleshoot issues
• Partner with product, design, and analytics teams to build dashboards, tools, and data‑driven features
• Communicate technical tradeoffs and guide stakeholders toward the best solutions
• Participate in sprint planning, code reviews, and architectural discussions
