Senior Frontend Engineer (React + Chrome Extension)

TTEC Digital seeks a Senior Frontend Engineer (React + Chrome Extension) to join our team. This role is a full-time and fully remote opportunity!

The work:

We’re an innovation group inside TTEC (NASDAQ: TTEC), building the next generation of AI CX tools — automated QA, conversational analytics, knowledge assist, and agentic automation — for the world’s biggest brands and the millions of customers they serve. We move like an early-stage startup, backed by the scale, distribution, and enterprise client base of a company that’s been obsessed with customer experience since 1982.

This is the rare seat where getting in early actually matters at scale. TTEC is a public company at an AI inflection point. Ship the right products into thousands of live enterprise deployments and you don’t just move a metric — you move the trajectory of the company and the value of the stock. The leverage is real, and the work compounds.

Who we hire — the DNA:

Self-starters and do-ers with grit — hackers in the best sense, with a startup mentality and a show-me bias: working software over slides, prototypes over proposals.

Want to learn, love new technology. This platform is built on the latest technology, and that technology changes and advances monthly. You adapt to change quickly — new tools, new models, new priorities — without drama.

Master debuggers and problem solvers. You love solving complex problems, you think outside the box, and you multitask across domains without losing the thread.

AI-native. You work with AI on all levels — you understand the technology around you (LLMs, SLMs, RAG, knowledge graphs, agents, training, eval) and you use AI tools daily to exponentially increase your velocity.

Distributed-systems literate. High-efficiency, event-driven, low-latency systems are our world; you understand what that demands.

Innovators who ship. You demonstrate ideas easily, fail fast, and move forward. You make committed timelines and hit them.

You consider yourself exceptional — and you like winning. So do we.

No one will have everything in this description. We're looking for well-rounded, smart people who move fast.

What You Will Do:

The role:

Build the Agent UI shell, the Chrome extension, the slide-out / pill workspace, the Control UI, and the per-module panels.

This is the product wedge — what an evaluator demos in 5 minutes and decides "yes."

Real-time UI over live voice, desktop, and AI event streams, in a startup environment: 1-week sprints, Friday demos, fail fast and move forward.

What you'll own:

• React app + Chrome extension (Manifest V3, content scripts, injected iframe, page-overlay pill)
• WebSocket-driven real-time UI · plugin / module-federation patterns
• Screen-real-estate management
• The design system in code

Your committed timelines.

Who you are:

A self-starter with a show-me mentality — you move from prototype to real-world product quickly and demonstrate ideas with working UI, not mockups.

You love new technology and adapt fast when it changes.

Consistent by discipline: you use shared libraries and established patterns instead of reinventing per feature — consistency is what keeps a small team fast.

You use AI tools daily to multiply your velocity.

You consider yourself exceptional, love solving hard problems, and like winning.

What You Will Bring:

• 7+ years frontend; senior-level React + TypeScript mandatory. HTML5, JavaScript, and graphics skills all ++++ —
• You're a master of the browser platform itself, not just a framework user (canvas/SVG/WebGL, animation, rendering).
• Strong design/UI skills a +++ — you have taste; your UIs look and feel professional without a designer holding your hand.
• Real Chrome Extension experience — Manifest V3, content scripts, the messaging model, injecting UI over a host page. This is core, not a footnote.
• Strong API skills — you design and consume clean APIs, and you understand the backend messaging systems behind them (pub/sub, event streams, WebSocket) well enough to reason about ordering, reconnects, and state sync.
• Heavy WebSocket / real-time UI; you've built interfaces that update from a live event stream.
• Plugin / module-federation or dynamic-component-loading experience.
• Performance as a habit — render profiling, virtualization for dense data, sub-frame updates under a firehose event stream; the UI must never be the latency bottleneck.
• State management under streaming data — optimistic updates, reconnect/replay handling, conflict resolution.
• Extension security fluency — CSP, sandboxing, isolated worlds; we inject UI into other companies' pages and can never break or leak.
• Automated UI testing (Playwright-class) as part of shipping, not a QA handoff.
• Accessibility and keyboard-first flows as defaults — agents live in this UI 8 hours a day.
• A master debugger in the browser — DevTools is an extension of your hands; you see the render bug, the leak, the layout thrash.
• Go literacy is a plus (you'll read it).
