IDT is looking for a highly skilled Senior Frontend Developer who can take informal leadership over UI development among Net2Phone projects.

Net2Phone is a UCaaS platform that helps thousands of businesses around the world run their internal and external communications. The Unite Interface team owns the frontend layer of the Net2Phone product — the web app at app.net2phone.com, the Electron desktop client, and the family of embedded micro-apps that live inside them.

The interface group is 7 engineers split across two squads. You'll be joining SPOG — our chats & calls client for B2B users (web + desktop). SPOG is a React + MobX SPA that ships as both a standalone app and as an embedded experience inside the Unite shell, and it's the surface customers spend most of their day in.

Beyond SPOG, you'll touch other UI projects in the ecosystem — the shared component library, embedded micro-apps (dialer, receptionist console, sip trunking, admin), and the infrastructure that delivers them all (CloudFront, S3, Lambda@Edge) via AWS CDK.

Tech stack: React 18, TypeScript, MobX, Vite, Electron, AWS CDK, CloudFront, S3, Lambda@Edge, GitHub Actions, Jest / Vitest, Playwright.

### In this role, you will be responsible for:

Design and build features in SPOG (React 18, Vite, MobX) — and dip into other Unite UI projects where it makes sense.

Own the delivery infrastructure for our UI apps via AWS CDK: CloudFront distributions, S3 origins, Lambda@Edge routing, and the GitHub Actions that glue it all together.

Work on Lambda functions that sit in the request/response path of our UI (pod routing, telemetry ingestion, etc.) and the CDK stacks that deploy them.

Push the bar on UI architecture across the org — share patterns between squads, raise the floor on test coverage, performance budgets, and CI quality gates.

Partner with the PO on shaping work — propose tasks, scope trade-offs, and push back when it matters.

Mentor teammates informally, run internal meetups, and review code with intent.

This is a hands-on Senior role. You'll write code most days, but you're also expected to think a level above your own tickets.

### Requirements:

Strong ECMAScript 2016+ and TypeScript fundamentals.

Solid grasp of OOP and functional paradigms in a frontend context.

Experience with build systems (Vite, Webpack) and modern bundling concerns (code-splitting, tree-shaking, source maps, perf budgets).

Real experience designing responsive, performant interfaces and diagnosing the issues that come with them (re-renders, bundle bloat, network waterfalls, memory leaks).

Hands-on experience with AWS CDK (TypeScript). You've written and deployed at least one non-trivial stack.

Practical familiarity with CloudFront, S3, Lambda, and Lambda@Edge.

Experience with CI/CD pipelines, ideally GitHub Actions.

Good level of English (B2 or higher).

Russian - Native.

### Would be nice to have:

Experience with Electron or other desktop-shell work.

Experience with micro-frontend architectures (module federation, web components, runtime composition).

WebRTC / SIP / real-time communication background.

Docker, Jenkins, or other CI/CD platforms beyond GitHub Actions.

### We offer you:

Remote b2b (Georgia-Moldova) or on-site employment (Belarus-Moldova) work opportunity!

Stable job with long-term growth perspective.

Competitive salary with annual performance review.

Really good hardware.

An exciting and challenging job with talented people around.

Continuous learning and career growth opportunities.

Compensation for professional training, seminars, and conferences.

Referral program – get rewarded for helping us grow the team with talented people.

Company-supported English classes to enhance your professional growth.

More perks for the Minsk and Chisinau office employees.
