About the Role

As a Front End Engineer at GreenChoice, you will both design and build the web and mobile experiences our users interact with every day. This is a dual role. You will create the designs yourself, in Figma, and then bring them to life in React.js and React Native with Expo. You own the experience end to end, from the first wireframe to the shipped, responsive interface.

We are not looking for someone who only implements other people's mockups. You will be the person deciding how a feature should look and behave: mapping the user flow, designing the screens, prototyping the interactions, and then writing the code that makes it real. That means strong design judgment matters as much as strong engineering skills here.

You will work closely with product and backend engineers to ship features that feel fast, look right, and are genuinely easy to use. This role suits someone who is equally comfortable in a design file and a code editor, cares deeply about the details of the user experience, and wants full ownership of front end features from concept through production.

Key Responsibilities

Design:

• Own the UI/UX for front end features: take a problem or product idea and design the flow, screens, and interactions for it.
• Create wireframes, mockups, and interactive prototypes in Figma, and iterate on them based on feedback.
• Make the call on layout, visual hierarchy, typography, color, spacing, and interaction patterns so the result is clear and easy to use.
• Define and maintain a consistent visual and interaction language across web and mobile.
• Design the full picture, including the states that are easy to forget: loading, empty, error, edge cases, and responsive breakpoints.

Frontend Development:

• Build and maintain web applications with React.js and mobile applications with React Native and Expo.
• Implement your own designs as high-quality, pixel-accurate interfaces.
• Implement responsive design and ensure cross-browser and cross-platform compatibility.
• Manage application state cleanly using Redux, Context API, or similar tools.
• Build reusable, well-structured components and front end patterns.

Integration and Collaboration:

• Work with backend engineers to integrate REST and GraphQL APIs and ensure smooth data flow into the UI.
• Participate in code reviews and front end technical discussions.

Quality and Maintenance:

• Write unit and component tests to keep the interface stable.
• Keep code clean, well-documented, and reusable.
• Debug, optimize, and monitor front end performance, including load times and rendering.

Required Skills and Qualifications

• 3 to 5 years of experience, with a track record of both designing and building front end interfaces.
• Strong design ability: you can create your own designs in Figma (wireframes, mockups, prototypes), not just implement someone else's.
• A real grasp of UI/UX fundamentals: usability, visual hierarchy, typography, color, spacing, and interaction patterns.
• A portfolio or examples of work that show both the design and the built result.
• Strong proficiency in:
  • React.js
  • React Native with Expo
  • JavaScript (ES6+), HTML5, CSS3
• Experience with state management tools (Redux, Context API).
• Solid understanding of responsive design, cross-browser compatibility, and accessibility.
• Proficiency with Git and collaborative tools (Asana, Slack, code versioning workflows).
• Comfortable consuming and integrating REST and GraphQL APIs.
• Able to work independently in a startup environment and own features end to end, from design to deployment.

Nice to Have

• Experience with TypeScript.
• Familiarity with front end testing frameworks (Jest, Cypress, React Testing Library).
• Experience optimizing performance for mobile and low-bandwidth conditions.
• Experience building or maintaining a design system or component library.
• Familiarity with user research, usability testing, or analytics to inform design choices.
• A formal background or training in design (visual, interaction, or product design).
• An interest in sustainability, food systems, or health tech.

What We Offer

• Salary: $15000-$20000 USD per year (based on location & experience).
• Equity options in a growing early-stage startup.
• Flexible working hours and remote work opportunities.
• Mission-driven team with a collaborative and inclusive culture.
• A chance to have a real-world impact on how people eat and live healthier, more sustainable lives.
