About the role

Tools for Humanity is seeking a Product Security Engineer to safeguard World project products and services at scale. You will lead security across the development lifecycle and partner with engineering teams to embed secure design. You will conduct threat modeling, build automation pipelines with AI agents for vulnerability detection, perform code and infrastructure reviews in Rust/Go/Python, manage vulnerability remediation, and advance the Secure SDLC and bug bounty programs.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
