## Job description

🎤 WHY VOIZE? BECAUSE WE’RE MORE THAN JUST A JOB!

At voize, we believe the greatest gift to frontline workers is time - time to care, connect, and be present. Today, that time is lost to busywork and complex systems that pull them away from what matters most: people.

Our vision is to change that by building AI companions that seamlessly take over digital workflows. We don’t replace humans with technology - we amplify their impact.

Our mission is backed with a $50M Series A funding led by Balderton Capital, with support from HV Capital, Y Combinator and other leading VCs. Today, 2,000+ facilities trust voize, and over 200,000 users rely on our AI companion to ease their daily workload.

As a dynamic team, we combine first-in-class technology with meaningful social impact. And now, we’re looking for you to join us on this mission!

## 💡 YOUR MISSION

As a Senior Fullstack Engineer at voize, you will be a co-owner of voize's ML App - the in-house platform for annotation, data exploration, ML training orchestration, model evaluation, and the HIPAA-bearing data flows that move PHI from customer to model. Make in-house tooling good enough that revisiting Labelbox/Encord-style vendors is permanently off the table, and unblock HIPAA-compliant training on US customer data.

🚀 YOUR DAILY BUSINESS - NO TWO DAYS ARE ALIKE

- Co-own the ML App codebase (React/TS SPA + Kotlin services + Kotlin ETL on EKS)
- Design and ship features for data labelling, data exploration, ML training orchestration, model evaluation, model playgrounds, and ML-issue triage
- Drive the next iteration of in-house annotation tooling - UX, throughput, task-type extensibility - to the bar where vendor revisits are unnecessary
- Maintain CI/CD, EKS deploys, and LGTM-stack observability for ML App; triage and fix defects
- Pair with the Platform team on platform-side prerequisites (FGA proxy, OIDC) that the new training flows depend on

🤝 YOUR SKILLSET - WHAT YOU BRING TO THE TABLE

- 5+ years building production fullstack web apps with React + TypeScript
- Excellent Kotlin (or JVM) backend experience - services, ETL/data pipelines, schema design
- Demonstrated ownership of a complex, production-critical system
- Comfortable engineering with regulated / sensitive data (HIPAA, GDPR, BAA, PHI, or similar)
- Strong product / UX instincts (annotation, labeling, data exploration, ops UI)

🌱 GROWING TOGETHER - WHAT YOU CAN EXPECT AT VOIZE

- We are a fast-growing startup, that means you will tackle challenges, grow quickly, and make a real impact, giving frontline workers more time for people
- We foster an open, collaborative culture with regular team events, whether you work from our Berlin office or remotely across Germany
- Become a co-creator of our success with stock options
- Generous perks: 30 vacation days plus your birthday off, Germany Transport Ticket, Urban Sports Club, regular company off-sites, and access to learning platforms such as Blinkist and Audible, plus free language courses
- You decide when you work best, that means flexible working hours and a good hybrid set-up.

## About voize

## Company Overview
- **One-liner**: voize builds an AI companion for nurses that converts spoken notes into structured documentation, synced in real time to Electronic Health Records (EHRs), giving caregivers back up to 30% of their time per shift.
- **Entity Type**: Private (funded: Series A, Winter 2022 Y Combinator batch)
- **Headquarters**: Berlin, Germany
- **Founded**: 2020
- **Founders**: Fabio Schmidberger (CEO), Marcel Schmidberger (COO), Erik Ziegler (CTO)

## Core Business
- **Primary industry/industries**: Healthcare IT, AI-powered clinical documentation, skilled nursing and elder care
- **Target customers**: B2B – skilled nursing facilities, long-term care homes, and other healthcare providers employing frontline nurses
- **Mission or purpose statement**: “Give time back to those who care” – eliminate administrative burden so nurses can focus on people, not paperwork.

## Products & Services
- **[AI Companion for Nurses]**: A voice-based AI solution that runs locally on smartphones (no constant internet connection required). It listens as nurses speak during care, automatically structures and categorizes notes, and syncs them in real time to existing EHR systems. Designed for point-of-care documentation with offline capabilities.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed
- **Key Metric**: Total funding – $50M Series A (announced November 2025)
- **Notable Investors/Partners**: Balderton Capital (lead), HV Capital, Redalpine, Y Combinator (Winter 2022). Primary YC Partner: Nicolas Dessaigne.
- **Growth Signals**: 180,000+ nurses use voize; 1,100+ care facilities in Germany and Austria; 200M+ documented entries; 27% reduction in documentation time per shift; 9% more time on patient care; 15% reduction in staff turnover; care homes feature voize in job ads to attract nurses. The company is expanding into the US market.

## Competitive Advantages
- **Purpose-built for nursing** – developed in-house over tens of thousands of hours in care homes, not a generic AI repurposed for healthcare.
- **Offline-first architecture** – runs locally on smartphones, ensuring high data protection and continuous operation even when Wi-Fi fails, a first in healthcare AI.
- **Language & dialect support** – understands complex medical language, regional dialects, and non-native speakers, empowering diverse care teams.
- **Deep EHR integration** – bi-directional sync with all major EHRs for skilled nursing and long-term care, fitting naturally into existing workflows.

## Strategic Focus
- **European expansion and US market entry** – the $50M Series A will accelerate geographic growth and product development.
- **Expanding beyond documentation** – the AI companion will eventually cover all administrative workflows for frontline workers, starting with nursing.
- **Deepening integration with care facilities** – proven impact on nurse satisfaction and retention makes voize a tool that helps facilities attract and retain staff.

## Why Work Here
- **Culture & values**: Humans First, Aim for Epic, Act with Urgency, Care Always, Own the Outcome, Turn Complexity into Clarity. Emphasis on cross-functional collaboration, empathy, and making a real difference in healthcare.
- **Work policy**: Flexible work arrangements and remote-friendly policies – work from the Berlin office or from home, with the option to work from different EU countries.
- **Perks**: 30 vacation days + birthday off, Urban Sports Club membership, and a team that prioritizes connection and celebration alongside meaningful work.
- **Engineering culture**: “We make the complex simple” – the engineering team works on cutting-edge AI models, speech recognition, and offline mobile tech. High autonomy, iterative experimentation, and focus on results.
