We are scaling our engineering team and looking for multiple developers. We prioritize capability over tenure. We are looking for engineers who can architect and ship production-ready software with high autonomy. We value the quality of your output above the length of your resume.
Who We Are Looking For
You are a Professional. You take ownership of your work. You don't need to be micro-managed to deliver.
You Value Craftsmanship. You write clean, maintainable, and efficient code. You care about the long-term health of the codebase, not just closing tickets.
You Have High Agency. You identify problems and fix them before they are assigned. You are comfortable navigating ambiguity.

We are looking for a Senior Frontend Developer to spearhead the creation of a high-performance, embeddable component using a modern React stack. You will be responsible for the architecture and implementation of this widget, ensuring it is lightweight, fast, and easily integrated into third-party environments.
We need a specialist who focuses on code quality, type safety, and seamless UX. You will work closely with our UI/UX designer to translate high-fidelity mocks into working code, ensuring the embeddable solution functions perfectly across different contexts.
Key Responsibilities
Component Architecture: Architect and build a scalable, embeddable widget using React and TypeScript, utilizing Vite for optimized building and bundling.
Form Handling: Implement robust data entry flows using React Hook Form. You will ensure strict data integrity and user feedback using Yup for schema validation.
UI Implementation: Translate designs into responsive, accessible interfaces using MUI (Material UI). You must ensure styles are scoped correctly to avoid conflicts when the component is embedded on external sites.
Maps Integration: Implement interactive mapping features using React Leaflet, handling markers, popups, and user location data efficiently.
State Management & Data Fetching: Manage server state, caching, and synchronization using React Tanstack Query to ensure the component feels snappy and reactive.
Design Collaboration: Collaborate daily with the UI/UX designer to ensure technical feasibility and pixel-perfect implementation of designs.
Required Technical Skills
Core Stack: Expert proficiency in React and TypeScript with a deep understanding of modern hooks and functional components.
Build Tools: Experience configuring Vite for development and production builds.
Form Management: Deep experience with React Hook Form paired with Yup for validation logic.
UI Framework: Advanced knowledge of MUI (custom theming, overrides, and responsive layouts).
Mapping: Hands-on experience with React Leaflet or similar mapping libraries.
Data Layer: Proficiency with React Query/Tanstack Query for managing asynchronous data.
Embeddable Components: Experience building isolated, embeddable React components using Shadow DOM or other techniques to prevent style conflicts and ensure seamless integration.
Nice-to-Have Skills
Design Tools: Experience working directly within Figma (inspecting elements, exporting assets, and understanding design systems).
Testing: Experience writing unit and integration tests (Vitest, Jest, or React Testing Library).
Design Eye: The ability to spot visual inconsistencies and work with designers to fix them before deployment.
Communication: Clear communication skills to collaborate with the team and discuss architectural trade-offs.
For full-time: Flexible hours, just need to be online or attend calls from 10pm to 2am PH time.
For part-time: 10pm to 2am or 5am onwards PH time.
