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).
