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).
