At TTEC Digital, we coach clients to ensure their employees feel valued, and fully supported, because an amazing customer experience is an employee first process. Our vision is the same, a place where employees know they can thrive.

TTEC Digital seeks a Principal Software Engineer 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:
  • As this group's Principal Software Engineer, you will be the "right-hand" of the engineering leader and part of the org's leadership team.
  • You will be the organization's problem solver. Not an architecture title you hide behind — a coder who jumps into whichever squad is stuck, ships the hard thing, and moves on.
  • You will jointly own the Platform Architect responsibilities for C1 Platform Foundation. This is a fast-moving train in a startup environment: the tech we build on changes monthly, the plan changes with it, and you thrive on that.
  • Show-me mentality — your influence comes from the code you ship, demoed on Fridays like everyone else.
    • What you'll own:
  • The hardest problems in any squad · platform architecture decisions (event bus, plugin lifecycle, multi-tenancy, RBAC, schema registry) jointly with the engineering leader
  • Pattern-setting reference implementations
  • Training up the engineers around you — you raise the whole team's level · unblocking, by writing code, not memos.

    • Who you are:

  • A hacker in the best sense — self-starter, grit, thinks outside the box, loves solving complex problems, likes winning.
  • You quickly envision code and designs in your head, then prove them by building. You use AI throughout your development workflow
  • Code generation, refactoring, test scaffolding, debugging — as a genuine velocity multiplier, and you've embedded AI inside products, not just used it as a tool. Change doesn't rattle you; new technology energizes you.

    • What You Will Bring:

    • 12+ years hands-on, genuinely polyglot — fluent in 7+ languages across your career. Senior-level Go is mandatory; Python and TypeScript expected in the mix; a native/systems language a strong plus.

    • Breadth across multiple technologies and verticals — you've shipped in more than one industry and more than one architectural era, and adapted fast each time.

    • Deep understanding of high-capacity distributed systems and their failure physics — state management, race conditions, locking, contention, ordering, back-pressure. You've debugged these in production, not just read about them.

    • Multiple messaging systems (NATS / Kafka / Redpanda / RabbitMQ-class) and multiple database types and backgrounds — relational, KV, document, columnar, graph — and you know which fits and why.

    • Two clouds minimum, one deep; GCP strongly preferred as the deep one.

    • Strong AI knowledge — LLMs, SLMs, RAG, knowledge graphs, agents, training/fine-tuning, eval — and hands-on experience working AI into code: building AI-powered features and using AI-assisted development to move exponentially faster.

    • Troubleshooting/debugging master — the strongest debugger in the building. Reads unfamiliar code, a stack trace, or a flame graph and sees it. Knows where the breakpoint goes without flailing.

    • Problem-solves quickly and trains up others as a multiplier — pattern-matches instantly on distributed systems, real-time audio, browser internals, AI pipelines, high-throughput data models.

    • Floats by choice. Does not want to own a squad. Wants to own the hard 10%.

    • Sets patterns by shipping the reference implementation, not by writing the doc.
