Job Description

Spectrum One is Hiring

The Opportunity Spectrum One is a strategic engineering partner for high-growth startups and established corporations. Since 2015, we have helped our clients raise over $150M in funding. We are a profitable business with consistent double-digit year-over-year growth.

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.

Why Engineers Choose Us

  • High-Trust Environment: We hire adults. We don't track keystrokes or enforce arbitrary hours. We care about the quality of your output.
  • Deep Work: We minimize meetings to protect your focus time. We operate asynchronously by default.
  • International Standards: You will work with top-tier international clients, building systems that scale and handle real-world traffic.

Why Join Spectrum One

  • Real Strategic Influence: We expect engineers to drive technical decisions. You will have a direct hand in shaping the architecture and product roadmap.
  • Autonomy by Default: We reject the traditional agency model of churn and burn. We provide the context and the goal, then we trust you to execute.
  • A Culture of Excellence: You will be surrounded by high-performers who push you to be better. We believe in continuous evolution and provide the environment you need to do the best work of your career.
  • Top-of-Market Compensation: High base salary benchmarked against industry standards, plus annual performance-based bonuses.
  • Annual Summit: A fully-funded, company-wide Out of Country retreat to celebrate our wins.
  • Hardware & Gear: We provide the latest tech (MacBook Pro or equivalent) and other equipment to ensure your workspace is ergonomic and productive.
  • Professional Development Budget: We provide an annual budget for courses, certifications, books, and conferences. We want you to stay sharp.
  • Permanent Remote: Work from home or anywhere you are most productive.
  • Time Off & Wellness: Generous paid leave policy, full medical coverage (HMO), and mental health support for you and your dependents.

About The Role


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).

Soft Skills

  • 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.

Time Schedule

  • 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.
