Voice AI Engineer Jobs
The Future Is Conversational.

Voice interfaces are everywhere. Smart speakers, cars, healthcare, enterprise.
Companies need engineers who can build the voice experiences users expect.

Voice AI Is a Different Beast.

Speech recognition, synthesis, and dialog systems require specialized knowledge most AI courses don't cover.

Real-time latency requirements mean you can't just deploy standard ML models. Voice needs sub-200ms response times.

Platform fragmentation across Alexa, Google Assistant, Siri, and custom solutions makes it hard to build transferable skills.

Build Voice AI Skills That Transfer.

Meet Your Mentor

Zen van Riel

My aim has been the same for years: become a world-class AI engineer. Every career move I've made has been measured against that.

I started as a software tester on a $500/month internship in the Netherlands. Taught myself to code, learned to ship real systems, and worked my way to Senior Engineer at GitHub.

Then I left GitHub. I joined an AI research lab as Member of Technical Staff, where I currently build products for secure AI monitoring.

The cohort draws directly from my real experience so you can make progress fast.

I run this special cohort with only a few people because hands-on work with me is what it takes to bring you to become a world-class AI engineer.

"The coaching played a huge part in my success. I focused on AI fundamentals, the certification path, and soft skills like professional writing. Having access to expert guidance gave me confidence during interviews and helped me feel I was on the right path.

I built my own platform (simple but functional) and deployed it on AWS. I used it in my portfolio and showcased it during interviews. The way complex topics were explained, especially the restaurant analogy for AI systems, really stuck with me. Focusing on doing the basics well was absolutely essential."

Frequently Asked Questions

What does a Voice AI Engineer actually do?

Voice AI Engineers build the systems that let humans talk to machines naturally. This includes speech recognition (converting audio to text), text-to-speech (generating natural-sounding voice), dialog systems (managing conversations), and voice user interfaces. You might work on smart speakers, in-car assistants, healthcare documentation, customer service bots, or accessibility tools. The role combines deep learning, audio processing, and real-time systems engineering.

What background do I need for voice AI roles?

Most voice AI engineers come from either ML engineering (adding speech specialization) or audio/signal processing backgrounds (adding ML skills). A CS degree helps but isn't required. What matters more: strong Python skills, understanding of neural network architectures (especially transformers and sequence models), and some exposure to audio fundamentals. Many successful voice AI engineers are self-taught with strong portfolios.

How is voice AI different from general ML engineering?

Voice AI has unique challenges: real-time latency constraints (users expect instant responses), noisy real-world audio, streaming inference (processing audio as it arrives), and subjective quality metrics (what sounds 'natural'?). You also deal with platform-specific requirements (Alexa vs Google vs custom) and regulatory concerns in healthcare/automotive. The upside: it's a specialization that commands premium salaries and has less competition than general ML.

What portfolio projects should I build for voice AI jobs?

Projects that demonstrate real voice AI skills: 1) Custom voice assistant with multi-turn dialog, 2) Real-time transcription app with speaker diarization, 3) Voice cloning or TTS system with natural prosody, 4) Wake word detector trained on custom phrases, 5) Accent-robust ASR fine-tuned on specific domains. Deploy at least one project with real-time streaming. Open-source contributions to projects like Whisper, Coqui TTS, or Rasa also stand out.

Are there remote voice AI engineer jobs?

Yes, many voice AI roles are remote or hybrid. Startups like Deepgram, AssemblyAI, and ElevenLabs hire remotely. Large companies vary by team. The catch: some roles involving hardware integration or on-device optimization may require on-site work. Enterprise and healthcare voice AI often has more remote flexibility than consumer hardware roles.

What's the career path for voice AI engineers?

Voice AI engineers typically progress from individual contributor to tech lead to principal engineer or engineering manager. Specializations include: research (pushing state-of-the-art), platform (building voice infrastructure), product (shipping user-facing features), or ML ops (scaling voice systems). Some move into product management for voice products. The field is young enough that senior roles are attainable within 4-6 years for strong performers.

I've signed up for cohorts before and dropped out. How is this different?

It probably isn't, and you should hold the money. Most cohort dropouts are people who couldn't articulate what they were shipping when they signed up. That's why the consult exists, and why I turn down most applications. If we get on the call and you can't tell me what you'll have shipped at the end of week 8, I'll point you to the AI Native Engineer community until you can.

I'm not pivoting careers. I want to build a product. Does this still work?

Yes, the cohort works for people shipping their first serious AI system whether the goal is to land a senior role or to launch a product. The shipped system serves both equally well.

Do I need prior AI experience?

You need to be able to code in Python or TypeScript. Complete beginners can follow the classroom they get access to before the cohort sessions to come in well-prepared.

How much time will this take?

You'll spend 3 hours every Tuesday in the live session and roughly 3 hours of async work in between, for 8 weeks. The Tuesday session time is fixed.

What does it cost?

It's a four-figure investment that we discuss during the 30-minute consult, alongside whether the cohort is the right fit for your project.

Can I do this while working full-time?

Yes, most attendees do. The live session is one Tuesday a week and the async work fits around your existing schedule, as long as you can carve out roughly 6 hours a week.

I accept those who have the highest chance of success.

In the 30-minute call we discuss your goals and whether you are ready for the program.
