Junior AI Voice Engineer (Germany)

We are hiring Junior AI Voice Engineers to work on AI voice agent systems used by businesses across multiple industries.

This role is based in Germany.
We do not hire through CVs or interviews alone — instead, we hire through real work and performance.

This page explains how we hire.

About the Role

As a Junior AI Voice Engineer, you will work on AI-powered voice agents that handle inbound and outbound calls for real business use cases.

This is a hands-on engineering role focused on building, testing, and improving AI systems, not theory or coursework.

Responsibilities

In this role, you will:

• Build and improve AI voice agent workflows

• Design and test conversational logic for phone calls

• Handle edge cases, failures, and fallback scenarios

• Test and validate AI agent behavior in sandbox environments

• Work with senior engineers on AI system improvements

• Demonstrate completed solutions and explain technical decisions

Salary (Germany)

€3,000 – €3,600 net per month

Final compensation depends on tax class, location, and employment terms.

This compensation applies after hiring, not during the internship.

We do not believe that CVs or interviews alone are enough to evaluate AI engineers.

Instead, we hire through a performance-based internship and evaluation pathway.
This internship is how candidates prove they can deliver real results.

If you want to be hired, you must complete this evaluation path successfully.

How We Hire

Internship & Evaluation Path

To be eligible for a Junior AI Voice Engineer role, candidates must complete our internship program.

Internship details:

• Duration: 4 months

• Commitment: 15–20 hours per week

• Location: Remote

• Type: Unpaid

• Purpose: Skill evaluation and hiring selection

This internship is not a job.
It is a structured evaluation process to be hired for the job.

What You Will Work On During the Internship

During the internship, you will work on production-grade AI voice system projects designed to reflect real business use cases. These projects mirror the type of work required in real client environments, while being executed in sandboxed and controlled setups for evaluation purposes.

This internship is delivery-focused, not observational.
You are expected to build complete solutions independently and demonstrate working results.

Core Responsibilities During the Internship

You will be responsible for:

• Building AI voice agents end-to-end using modern AI voice platforms

• Designing full call flows (greetings, intent handling, fallbacks, transfers, endings)

• Creating automations and backend logic that support AI agent behavior

• Connecting AI voice agents with external systems such as CRMs, calendars, databases, and APIs

• Delivering working, testable solutions for realistic business scenarios

• Debugging failures, edge cases, and unexpected call behavior

• Improving agent reliability, performance, and conversation quality

• Working independently on assigned evaluation projects and internal simulations

AI Voice Platforms

You should be able to:

• Configure AI voice agents from scratch

• Set up prompts, system instructions, and logic

• Handle interruptions, silence, retries, and fallback paths

• Configure call transfers, voicemail handling, and call termination

• Test and iterate agent behavior based on real call scenarios

(Exact platforms may vary. The ability to learn and adapt quickly is mandatory.)

Automation & Workflow Tools

You should be able to work independently with tools such as:

• Make.com

• n8n

• Zapier

You should know how to:

• Build multi-step automation workflows

• Trigger automations from calls, webhooks, or events

• Send and receive data via APIs

• Handle conditions, delays, retries, and errors

• Maintain clean, reliable automation logic

API & System Integration

You should be comfortable with:

• Webhooks

• REST APIs

• JSON data structures

And connecting AI agents to:

• CRMs

• Calendars

• Spreadsheets

• Internal tools

• Simulated client systems

You do not need to be a backend engineer, but you must understand how systems communicate.

Independence & Work Style (Very Important)

This internship is not suitable if you require:

• Step-by-step instructions

• Constant supervision

• Detailed tutorials or hand-holding

You are expected to:

• Read documentation independently

• Test and debug issues on your own

• Deliver working solutions without micromanagement

• Take ownership of tasks and outcomes

What You Do NOT Need

You do not need:

• A formal computer science degree

• Prior corporate job experience

• Perfect knowledge of every tool

What matters is:

• Practical ability

• Speed of learning

• Reliability

• Execution quality

Important Note

This is a performance-based evaluation internship.

The work you complete is designed to reflect real production requirements, and successful performance is the basis for hiring decisions.

If you enjoy building systems that behave like real-world solutions and are comfortable being evaluated on results, this internship is designed for you.

Performance & Rewards

The program is competitive.

• Performance determines continuation

• Not all participants complete the program

• Missed deadlines or low performance may result in removal

During the final month, selected interns may receive:

• Performance-based rewards for successfully completed tasks

These rewards depend entirely on results.

Hiring Eligibility

Only candidates who:

• Successfully complete the internship

• Achieve a 90+ performance score

• Demonstrate consistency and reliability

become eligible for interviews for Junior AI Voice Engineer roles in Germany for Voxero AI.

Who Should Apply

This program is suitable for people who:

• Are actively looking for a job in AI or engineering

• Have basic programming and AI experience

• Can work independently without step-by-step guidance

• Are comfortable with performance-based evaluation

• Can commit consistently for 4 months
