Collaboration Overview

Duelbits is seeking to collaborate with a Senior Front End Developer who can take strong ownership of our web interfaces, frontend architecture, and user-facing performance across multiple platforms.

As a Service Provider, you will work closely with Lead Developers, Product, Design, QA, and backend contributors to design, implement, and evolve scalable, high-performance frontend solutions. This role requires deep frontend expertise, strong technical judgement, and the ability to influence standards and best practices through hands-on delivery.

You will be trusted to make frontend architectural decisions, identify improvement opportunities, and contribute meaningfully to the overall engineering direction of the platform.

Technology Ecosystem

You will operate within a modern frontend-focused environment that includes:

• Frontend: React, TypeScript, Angular
• Backend collaboration: Node.js, NestJS (integration-focused), GraphQL
• Data & APIs: RESTful APIs, event-driven systems

Experience across the full stack is beneficial, but this role is frontend-specialised, with an emphasis on architecture, performance, and user experience.

• Lead the technical design and implementation of complex frontend features, views, and workflows.
• Define and evolve frontend patterns, component structures, and state management approaches aligned with Company standards.
• Identify frontend technical debt, performance bottlenecks, or maintainability risks and propose actionable improvements.
• Contribute to tooling, libraries, and architectural decisions that impact frontend scalability and consistency.

Front End Development & Delivery

• Design, develop, test, and deploy high-quality frontend features using React, TypeScript, and related technologies.
• Deliver responsive, performant, and accessible user interfaces across desktop and mobile devices.
• Collaborate closely with Designers to translate Figma designs into accurate, maintainable, and scalable UI implementations.
• Work with backend developers to integrate APIs cleanly and efficiently.
• Break down complex requirements into actionable frontend tasks and provide accurate effort estimates.
• Proactively remove blockers and ensure timely delivery of assigned work.

Code Quality, Testing & Performance

• Set a high bar for frontend code quality, maintainability, and readability.
• Write and maintain unit, integration, and UI tests where appropriate.
• Participate in and lead code reviews, providing clear, constructive technical feedback.
• Ensure frontend implementations meet non-functional requirements, including performance, accessibility, security, and reliability.
• Diagnose and resolve complex frontend issues, including production bugs and performance regressions.

Documentation & Engineering Practices

• Produce and maintain clear documentation for frontend systems, components, and patterns.
• Promote best practices around performance optimisation, accessibility (a11y), observability, and frontend security.
• Participate in internal demos, technical discussions, and continuous improvement initiatives.

Collaboration & Mentorship

• Work closely with Product Managers, Designers, QA Engineers, and Engineering leads to ensure aligned and predictable delivery.
• Provide visibility into frontend risks, dependencies, and technical constraints.
• Offer informal mentorship, guidance, or pair-programming support to other frontend or full stack developers when requested.
• Support onboarding of new contributors by providing frontend system context and documentation.
  

Required Capabilities

The following capabilities are imperative for this collaboration:

• Significant experience as a Front End Developer delivering complex, production-grade web applications.
• Strong expertise in React, TypeScript, and modern frontend development practices.
• Proven experience owning frontend features or areas end-to-end.
