Senior Frontend Engineer

B2spin is currently expanding its engineering division and is seeking a seasoned Senior Frontend Engineer to join their global, remote-first team. This organisation specialises in the Free-to-Play social casino sector, focusing on building high-engagement gaming products that reach players across the globe. By integrating an AI-driven approach into their technical workflows, they are looking for a forward-thinking developer who is comfortable working at the intersection of gaming performance and user experience.

About the role

This position is ideal for a developer who enjoys working across the full software development lifecycle. You will not be confined to siloed coding tasks; instead, you will be deeply involved in everything from initial sprint planning sessions to the final deployment of features. The team operates in a collaborative environment where effective communication between developers and product owners is paramount to success.

The role requires a high degree of technical independence and a commitment to maintaining a robust, scalable codebase. You will be expected to produce testable code that holds up under the demands of a global user base, ensuring that every product release is seamless and high-performing.

As a Senior Frontend Engineer, your daily contributions will impact the technical direction of their gaming suite. Your core responsibilities will include:

• Developing, maintaining, and scaling consumer-facing web and mobile applications.
• Ensuring your code is clean, testable, and optimised for production environments.
• Managing the integration of third-party services, including external APIs and complex analytics tracking.
• Prioritising technical SEO and PageSpeed metrics to ensure the best possible user experience.
• Collaborating with cross-functional teams to translate product requirements into high-quality technical solutions.

What they're looking for

B2spin is looking for a professional with a strong commercial background who understands how to bridge the gap between frontend aesthetics and backend functionality. To be considered, you should possess:

• Expert-level proficiency in React, TypeScript, and Next.js.
• Advanced knowledge of HTML and CSS, with a demonstrated ability to create responsive, cross-browser compatible interfaces.
• Practical experience working with Figma to implement precise UI/UX designs.
• A proven track record in SEO optimisation and site performance tuning.
• An interest in or willingness to expand your skillset into cross-platform development for mobile devices.
• High proficiency in English (B2+ level), ensuring clear communication within a remote, distributed team.

For South African developers, a role of this nature at a global firm often falls within the upper-tier of the local market, particularly when remote work is coupled with high-demand tech stacks like Next.js and TypeScript. In the local gaming and high-performance web sector, companies are increasingly prioritising candidates who can demonstrate end-to-end architectural thinking. Successfully securing a role like this typically paves the way for a career in international remote engineering, which offers excellent exposure to global production environments and competitive, market-leading remuneration packages.

• Strong commercial experience in React, TypeScript, and Next.js;
• Motivation to grow into cross-platform development (web and mobile);
• End-to-end thinking across frontend, backend, and infrastructure;
• Solid expertise with HTML/CSS, including responsive and cross-browser development;
• Experience with third-party integrations (external APIs, analytics);
• Proven track record with SEO optimizations and PageSpeed improvements;
• Strong UI/UX experience with Figma;
• Good English skills in speaking and writing (B2+).
