Software Engineer, ML Ops and Platform

About the Company:

Tools for Humanity (TFH) designs and builds technology behind World. World is building a real human network designed to accelerate people in the age of AI. As bots and autonomous agents reshape the internet, people, institutions, and applications need a trusted way to confirm who is a real human while preserving privacy. The TFH and World tech stacks make this possible: the Orb verifies real, unique people, World ID proves it privately, and World App puts these capabilities, and more, in people’s hands. Together, they add a human layer to an AI-driven internet.

World is already running at a global scale. More than 17 million people across 160 countries have verified with World ID, and more new Orb verifications take place each week. World App is already among the most used wallets globally. Developers are integrating World ID to build safer online experiences and create spaces where real people can participate, earn, and be recognized in ways AI simply can’t replicate.

Founded in 2019, TFH has more than 400 people across hardware, software, AI, cryptography, mobile engineering, and global operations. Our teams come from OpenAI, Tesla, SpaceX, Apple, Google, Stripe, Meta, Coinbase, Palantir and MIT Media Lab. We’re backed by leading investors, including a16z, Khosla Ventures, Bain Capital Crypto, Blockchain Capital, Variant, Tiger Global, and Coinbase Ventures, as well as prominent operators and founders across fintech and AI.

TFH and World have been featured on the cover of TIME Magazine , highlighted in Fast Company’s Next 5 in Fintech, and explored in a Bloomberg deep dive . The New York Times , Bankless and TechCrunch have all recognized our collective progress in identity, cryptography, AI, and global-scale hardware deployment. Our leadership is also named to the Time AI 100 . Learn more about the newest product launches from our Liftoff event.

About the Team

We are building a planet‑scale biometric recognition system that will serve more than a billion users and enable them to become part of the World protocol. We use cutting-edge Machine Learning models deployed on custom hardware to enable high-quality image acquisition, identification, and fraud prevention, all while requiring minimal user interaction.

We are building a biometric recognition and fraud detection engine that works on the 1bn people scale. Therefore, its performance needs to outperform all the current recognition technologies. We leverage our powerful custom-made iris recognition and presentation attack detection device, the Orb, combined with the latest research from the field of AI and Deep Learning.

To reach our next milestone—continuous, trustworthy ML innovation across millions of edge devices—we’re hiring a Senior ML Platform & Ops Engineer to own the ML lifecycle from data to device. You’ll design and operate production-grade pipelines that transform state-of-the-art ML research into deployed models with clear telemetry, rollback, and reproducibility. If you thrive on building self‑service platforms that turn research ideas into reliable, observable production systems, we’d love to meet you.

Key Responsibilities

• Design, build, and operate reliable, observable infrastructure for training, evaluation, telemetry ingestion, and deployment.
• Maintain CI/CD workflows and automated pipelines.
• Edge‑aware rollout services with staged deployment, A/B experimentation and instant rollback across Orbs, Orb Mini and Mobile Apps.
• Develop secure APIs and backend services that expose governed datasets and model artefacts at scale.
• Implement automated checks, drift detection, and alerting for real-time model monitoring.
• Champion best practices in data lineage, reproducibility, privacy‑by‑design, security and secure edge delivery.
• Collaborate across ML research, product, and firmware teams to streamline delivery and feedback loops.

About You

• 5+ years building ML infrastructure, data platforms, or production ML systems at scale.
• Track record of delivering platforms and CI/CD pipelines used daily by ML or data teams.
• Hands-on experience running large-scale training on multi-tenant GPU clusters to maximize throughput and reliability.
• You’ve built versioned dataset & lineage systems with slice-level provenance and governed access, making every model reproducible to the exact data, features, code, and config used.
• Deep understanding of containerisation (Docker) and orchestration (Kubernetes/EKS) plus Infrastructure‑as‑Code (Terraform/CDK/Cloudformation).
• Strong backend engineering skills in Python and/or Go; you value clean, maintainable code.
• Deep understanding of modern CI/CD, model packaging, and observability practices.
• Comfortable operating production systems, defining SLAs, and handling rollout or incident workflows.
• Comfortable using modern Agentic AI development
