About WOLF Qanawat

WOLF Qanawat are reimagining how people connect and engage through interactive audio entertainment and social communities. Our platform brings together live stages, shows, creators, and gaming experiences. We are building a dynamic team to power the next evolution of our web presence, and we are looking for a Senior Frontend Web Engineer to play a key role in that growth.

The Opportunity

They are evolving their core web application into a distinct, rich product experience that stands alongside their mobile apps. This means reaching parity on key product functionality—like live gifting, content creation, and interactive audio/gaming features—while modernizing their technical foundation.

You will join their Web Chapter to lead feature development, drive technical improvements, and help navigate an ongoing, multi-year migration from a legacy Polymer application to a modern React and TypeScript architecture.

About 90% or more of your work will focus on their main user-facing application, alongside occasional contributions to our internal admin panel, marketing pages, and legacy site integrations.

What You’ll Do

• Take Ownership: Lead projects end-to-end from initial concept through to rollout, making architectural choices that balance rapid delivery with long-term code health.

• Modernize the Stack: Contribute directly to their Polymer-to-React migration, introducing modern design patterns, component architectures, and best practices.

• Ship Impactful Features: Build complex, dynamic, and highly interactive user interfaces in cross-functional squads alongside backend engineers, QA, and product teams.

• Maintain Quality & Workflows: Improve development workflows, refine UI consistency, and maintain high standards through constructive code reviews.

• Mentor & Collaborate: Share technical knowledge within the web chapter and collaborate across engineering teams to tackle challenging projects autonomously.

What They’re Looking For

Essential (Must-Have)

• Senior Engineering Depth: Proven track record building complex, highly dynamic, interactive web applications (beyond static websites or basic storefronts).

• Modern Framework Expertise: Mastery of at least one modern frontend framework (React, Vue, Angular, etc.).

• Autonomy & Problem Solving: Demonstrated ability to take ownership of complex technical problems and drive projects to completion with minimal guidance.

• Collaboration & Communication: Clear, effective spoken and written English, with the ability to collaborate smoothly across engineering squads.

• UK Work Authorization: Pre-existing full right to work in the UK.

Desirable (Nice-to-Have)

• React & TypeScript: Direct, hands-on experience with React and TypeScript.

• Legacy Migrations: Experience migrating legacy frameworks (e.g., Polymer) to modern frontend stacks.

• Design Systems: Experience working with structured UI design systems.

• Remote Experience & Stability: A track record in hybrid/remote setups and a stable career history.

What is on Offer

• Competitive Salary: £52,000 – £58,000

• Flexible Hybrid Working: Minimum 2 days per week in our Cramlington office

• Time Off: 25 days annual leave (plus increases for long service) + discretionary holiday break between Christmas and New Year

• Early Finish Fridays

• Perkbox Subscription & Competitive Pension Scheme
