About the Role

As a Senior Full Stack Developer at GreenChoice, you will own the design and delivery of end-to-end solutions across our user-facing applications and backend systems. You will work across the stack, building web and mobile experiences with React.js and React Native, and designing the APIs, services, and data pipelines that sit behind them with Node.js and modern databases.

Beyond shipping features, you will set technical direction. You will lead architectural decisions, raise the engineering bar through code review and mentorship, and help shape how the team builds. This role suits someone who has spent years across the full stack, has strong opinions grounded in experience, and wants real influence over the product and the roadmap in a fast-paced, agile environment.

Key Responsibilities

• Architecture and Technical Leadership:
• Lead the design of full stack features, from data model to user interface, and make the trade-off calls that keep systems scalable, secure, and maintainable.
• Drive architectural decisions and document them so the rest of the team can build on them.
• Identify technical debt, performance bottlenecks, and reliability gaps, then plan and execute the work to address them.

Frontend Development:

• Build and maintain web applications with React.js and mobile applications with React Native and Expo.
• Translate Figma designs into high-quality, pixel-accurate interfaces.
• Set patterns for responsive design, state management, and cross-platform consistency that the team can reuse.

Backend Development:

• Design, implement, and maintain RESTful and GraphQL APIs using Node.js and Express.
• Model, query, and optimize data across relational and NoSQL databases (MySQL, PostgreSQL, MongoDB, Redis).
• Own data integrity, performance, and scalability across services.
• Collaboration and Mentorship:
• Partner with product, design, data, and infrastructure teams to scope and deliver features end to end.
• Mentor mid-level and junior engineers through code review, pairing, and design discussions.
• Help define engineering standards, testing practices, and delivery processes.

Quality and Maintenance:

• Write unit and integration tests and hold the team to a high standard for coverage and stability.
• Keep code clean, well-documented, and reusable.
• Debug, optimize, and monitor performance across the stack.

Required Skills and Qualifications

• 4-6 years of full stack development experience, including time owning features or systems end to end.
• Demonstrated experience leading technical design and mentoring other engineers.

Strong proficiency in:

• Frontend: React.js, React Native with Expo, JavaScript (ES6+), HTML5, CSS3
• Backend: Node.js (Express or similar), REST and GraphQL APIs

• Databases: SQL (MySQL or PostgreSQL) and NoSQL (MongoDB or Redis)

• Strong experience implementing Figma designs accurately.

• Proficiency with Git and collaborative tools (Asana, Slack, code versioning workflows).

• Solid grasp of responsive design, cross-browser compatibility, and accessibility.

• Experience with state management tools (Redux, Context API).

• Comfortable working independently in a startup environment and taking full ownership of outcomes.

Nice to Have

• Knowledge of cloud platforms (AWS, DigitalOcean, GCP) and containerization (Docker, Kubernetes).
• Experience with CI/CD pipelines and DevOps practices.
• Experience with search and indexing systems (Elasticsearch, OpenSearch).
• An interest in sustainability, food systems, or health tech.

What We Offer
