About the Company:
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. Our products make this possible: the Orb verifies real people, World ID proves it privately, and World App enables and distributes the new applications made possible by this technology. Together, they form a new layer for AI internet.
Weâre one of the fastest-growing networks in tech. More than 17 million people across 160 countries have verified with World ID, and we complete over 350,000 verifications 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 canât replicate.
World was founded in 2019 and launched globally in 2023. We are 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. Weâre 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.
World has been featured on the cover of TIME Magazine, highlighted in Fast Companyâs Next 5 in Fintech, and explored in a Bloomberg deep dive. The New York Times, Bankless and TechCrunch have all recognized our progress in identity, cryptography, AI, and global-scale hardware deployment. Our leadership is also named to the Time AI 100.

This opportunity is with Tools for Humanity.
Our multidisciplinary teamâs mission is to detect & respond to attacks against the global-scale identity World ID service, which leverages mobile apps (Android and iOS), a unique hardware device (the Orb), cloud-hosted APIs, and operations on the (Ethereum-based) Worldchain blockchain to provide privacy-preserving âproof of humanâ. Together, we apply expertise in mobile devices, hardware, cloud infrastructure, application security, intrusion detection, machine learning/AI, blockchain, incident response, and more to solve these novel challenges.
We are building an entirely new automated detection and response system. Right now it needs to protect the 17 million+ verified World ID users processing millions of identity and financial transactions a day, and it will need to rapidly scale to protect billions of users using trusted and untrusted hardware, much of which we will not own. We will publish audit events to the public blockchain for the highest possible transparency and trust of the World ID system, and build decentralized detection & response using those logs. We need to do all this while maintaining the strongest possible privacy protections.
This team works closely with the teams building the core technologies, because D&R and Privacy are foundational elements of the World Network.
We have a variety of mobile resources that need security controls and detection: apps for users to signup at an Orb and manage their currency wallets, apps for Orb operators to manage their devices and team, and a future Android-based device as a successor to the Orb.
Our user app also contains a âMini Appâ ecosystem that includes 3rd party developers, and is intimately tied to both the digital identity (WorldID) and blockchain transactions.
You will work with our App engineering teams to address app and Mini App risks. You will also work with the Device and Device Security teams on securing the Android operating system of the next-generation Orb device.
Some travel (10-20% maximum) is expected, especially to our office in Munich, Germany where most of the Orb hardware and software teams are located.
5-8 years experience in offensive and defensive Android security. This is a âpurple teamâ role where you challenge the security of the apps and devices, advise and assist Engineering on implementing controls, develop Detection capabilities for mobile devices, and (when on call) drive incident response for any security incidents (not just mobile).
Sound knowledge of Security fundamentals.
Deep knowledge of mobile attacks and defenses.
Some experience developing Android apps (Kotlin).
Analyst-level Python coding (building analysis pipelines in an existing environment).
Willing to participate in an on call rotation and learn incident handling (or relevant experience)
Strong critical thinking, communication, and leadership skills
Comfort working cross-functionally with peer teams to negotiate and reach consensus solutions that improve security and privacy
Energized by working in a fast-paced, collaborative environment
If you don't think you meet all of the criteria but still are interested in the job, please apply. Nobody checks every box, and we're looking for someone excited to join the team.
Engineer-level coding in Kotlin (implementing security frameworks)
Experience hacking or developing iOS apps (Swift)
Reported CVEs (especially for mobile apps and Android)
Collected Bug Bounty awards
Participated in / won CTF (Capture The Flag) competitions
