🎤 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
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
