Lead Frontend Engineer (React).

We are looking for a Lead Frontend Engineer for UI CORE, one of three frontend teams at net2phone. The team owns the web side of our cloud communications product: the main web app, the admin console, the supervisor and receptionist consoles, the call queues wallboard, the dialer, and the shared UI platform packages underneath them.

This is a hands-on lead role. You will write code, own technical decisions, and lead a team of three mid-level engineers, one senior engineer and two QA engineers.

Stack: React, TypeScript, micro-frontends, AWS (CloudFront, Lambda@Edge, S3), GitHub Actions, Jira, Scrum.

• Technical direction for the team's applications and the shared UI platform.
• Delivery to production. Our apps ship to ten production pods through CloudFront and Lambda@Edge with a service-worker entrypoint and a versioned CDN. Frontend delivery here is real infrastructure work, not a build step.
• The team's application template, which every new app in the organisation starts from.
• Code review standards, technical debt, and the quality bar.
• The team's scrum process.
• Representing frontend in architecture discussions with backend, platform and product leads.

• Experience leading a small distributed frontend team, including growing engineers. Not only mentoring: owning what the team builds and how.
• Strong React. We are finishing a large migration from Angular, so you have seen legacy and greenfield in one codebase.
• You have owned frontend delivery to production, not just components: builds, caching, CDN, releases, and what happens when a release breaks in production.
• AI-assisted development as daily practice. The team already works this way, with agentic tooling on our own codebases. You should be at least at their level.
• Comfortable running scrum for your team.
• English B1 or above. The team works in Russian, product and stakeholders in English.

• Micro-frontends.
• AWS at the level a frontend owner needs: CloudFront, Lambda@Edge, S3, CloudWatch.
