  • • Are you a passionate and driven builder eager to make a tangible impact on a global scale? Tools for Humanity (TFH) is seeking exceptional individuals to join our prestigious TFH Engineering Fellowship program. This is a unique opportunity for early-career engineers to dive headfirst into complex challenges, contribute to groundbreaking products, and grow alongside a world-class team at the forefront of AI and human verification.
  • • At TFH, we are building the future of the internet – a real human network designed to empower individuals in the age of AI. As autonomous agents and bots increasingly reshape the digital landscape, the need for trusted methods to confirm human identity while preserving privacy has never been more critical. Our suite of products, including the Orb for identity verification, World ID for private proof of humanity, and World App for accessing new applications, forms a foundational layer for this AI-powered internet.
  • • The TFH Engineering Fellowship is meticulously designed to provide fellows with hands-on experience and significant responsibility. You won't be just observing; you'll be actively contributing to the development and deployment of products used by millions worldwide. This program is an accelerated path to becoming a full-fledged engineer within our organization, offering mentorship, challenging projects, and exposure to cutting-edge technologies.
  • • As a Fellow, you will have the opportunity to work across various engineering disciplines, gaining exposure to areas such as:
  • • **Software Development:** Contribute to the backend services, mobile applications (iOS/Android), and web platforms that power our ecosystem. You'll be involved in designing, coding, testing, and deploying robust and scalable solutions.
  • • **Hardware Engineering:** Participate in the development and refinement of our unique hardware devices, such as the Orb, which are crucial for our identity verification process. This could involve embedded systems, firmware development, or hardware testing.
  • • **Cryptography and Security:** Engage with the intricate cryptographic protocols that underpin our privacy-preserving identity solutions. You'll learn about secure system design and contribute to maintaining the integrity and security of our network.
  • • **AI and Machine Learning:** Explore the integration of AI technologies within our products, potentially contributing to areas like anomaly detection, user experience enhancement, or data analysis.
  • • **Infrastructure and DevOps:** Work on the systems that ensure our services are reliable, scalable, and performant. This includes cloud infrastructure, CI/CD pipelines, and monitoring tools.
  • • The fellowship emphasizes learning by doing. You will be paired with experienced mentors who will guide you through your projects, provide constructive feedback, and help you navigate the complexities of building at a global scale. You'll be encouraged to ask questions, experiment with new ideas, and take ownership of your work. The goal is to foster an environment where you can rapidly develop your technical skills and professional acumen.
  • • Our team comprises individuals from leading technology companies and research institutions like OpenAI, Tesla, SpaceX, Apple, Google, Stripe, Meta, Coinbase, Palantir, and MIT Media Lab. By joining the fellowship, you become part of this elite group, learning from the best and contributing to a mission that has the potential to redefine digital identity and human interaction in the AI era.
  • • The impact of your work at TFH is profound. You will be contributing to a network that has already seen over 17 million people in 160 countries verify their humanity, with hundreds of thousands of verifications happening weekly. World App is already one of the most utilized wallets globally, and developers are actively integrating World ID to build safer, more equitable online experiences. Your contributions will directly enable real people to participate, earn, and be recognized in ways that AI cannot replicate, fostering a more trustworthy and human-centric internet.
  • • This fellowship is more than just an internship; it's a launchpad for a successful career in technology. We are looking for individuals who are not afraid to tackle ambitious goals, who possess a strong foundation in computer science principles, and who are driven by a desire to build impactful products. If you are ready to take on significant challenges, learn at an unprecedented pace, and contribute to a company shaping the future, we encourage you to apply.
  • • The fellowship program is structured to provide a comprehensive learning experience, including:
  • • **Project-Based Learning:** Work on well-defined projects that have real-world applications and contribute directly to our product roadmap.
  • • **Mentorship and Guidance:** Receive dedicated support from senior engineers and leaders who are experts in their respective fields.
  • • **Cross-Functional Exposure:** Gain insights into different facets of engineering and product development within a fast-paced startup environment.
  • • **Professional Development:** Participate in workshops, tech talks, and learning sessions designed to enhance your technical and soft skills.
  • • **Networking Opportunities:** Connect with a diverse group of talented individuals within TFH and the broader tech community.
  • • We believe in empowering our fellows to become future leaders. This program is designed to identify and nurture top talent, providing them with the resources and opportunities needed to excel.
