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
The Crypto Platform team builds and operates the foundational services that power products interacting with World Chain. The team owns the full transaction lifecycle, including state reads, calldata construction, smart contract interactions, backend execution paths, transaction submission, and the high-availability infrastructure required to process transactions reliably at scale.
The team also maintains event ingestion and indexing pipelines, using Temporal to provide a consistent, resilient source of truth for downstream systems.
Engineers work closely with product teams to ensure wallet features, Mini App integrations, and ERC-4337-based flows remain robust across regions, providers, and failure domains. The team’s mandate also includes broader crypto infrastructure such as RPC load balancing, transaction simulation, security tooling, and multiprovider redundancy.
About the Opportunity
You will work across crypto platform infrastructure, blockchain engineering, and distributed systems, collaborating closely with product engineers, backend teams, protocol engineers, infrastructure, and security. This role requires strong ownership, sound engineering judgment, and a focus on reliability, as your work will underpin mission-critical features across the organization.
About You
You can reason clearly about complex systems and enjoy working on difficult problems. You learn new domains quickly, take ownership of the systems you build, and drive projects to completion. You are comfortable operating in unfamiliar territory, whether that involves understanding a new protocol, diagnosing a distributed systems failure, or designing a more reliable transaction execution path.
You exercise sound engineering judgment and can turn ambiguity into concrete execution plans. You communicate effectively, collaborate well across disciplines, and maintain high standards for reliability, correctness, and security.
Above all, you are curious, driven, and energized by building foundational infrastructure that supports critical product experiences at scale.
Key Responsibilities
- Write clean, efficient, and maintainable code in Go, Rust, and TypeScript.
- Design and implement highly reliable services for transaction execution, state access, calldata construction, smart contract interaction, and event ingestion.
- Build and extend secure indexing and data processing pipelines using Temporal as the orchestration layer.
- Develop and maintain smart contracts required by product workflows.
- Improve the resilience of blockchain reads and writes through RPC load balancing, failover strategies, multiprovider redundancy, and transaction simulation.
- Own features from design through deployment, including technical design, documentation, testing, observability, and operational readiness.
- Partner with product engineering, protocol, infrastructure, and security teams to deliver scalable, fault-tolerant onchain systems.
- Contribute to monitoring, alerting, incident response, and long-term maintenance of production services.
- Help define platform abstractions that make it safer and easier for product teams to build onchain experiences.
Preferred Qualifications
- Experience building production backend systems in Go, Rust, or TypeScript.
- Experience with distributed systems, reliability engineering, or high-throughput backend services.
- Familiarity with Ethereum, EVM-based chains, smart contracts, account abstraction, or ERC-4337.
- Experience with event-driven systems, indexing pipelines, or workflow orchestration tools such as Temporal.
- Strong debugging skills across service boundaries, external providers, and blockchain infrastructure.
- A pragmatic approach to security, correctness, and operational excellence.

Target roles at the core of the product
Tools for Humanity's sponsorship activity centers on specialized technical positions tied directly to its identity and blockchain platform. Focus your applications on engineering, cryptography, and applied AI roles where your credentials most clearly match the company's core technology stack.
Understand which visa types they support
Tools for Humanity sponsors H-1B, H-1B1 visa, and TN visas, meaning Australians and Canadians have additional pathways beyond the H-1B lottery. If you hold citizenship in a TN-eligible country, highlight that in your application to broaden your options.
Lead with specialty occupation credentials
For H-1B sponsorship at a company like this, your degree must directly relate to the role. Biometrics, computer science, cryptography, and related engineering fields carry the strongest case. Generic software backgrounds without specialization are less likely to progress.
Time your outreach around H-1B registration windows
H-1B petitions must be filed in early April for an October start date. If you're targeting Tools for Humanity, aim to be deep in the hiring process by February so the company has time to prepare your registration before the March window closes.
Look for open roles on platforms that verify sponsorship history
Not every job board confirms whether a company genuinely sponsors visas. Migrate Mate surfaces verified sponsors so you can filter by real sponsorship history, letting you apply with confidence that Tools for Humanity has an active track record before you invest time in the process.
Position yourself as a mission-aligned candidate
Tools for Humanity operates in a highly specialized space combining identity technology and decentralized systems. Sponsorship decisions at focused companies often favor candidates who demonstrate genuine interest in the mission, not just technical fit. Tailor your materials to show you understand what they're building.
Frequently Asked Questions
Does Tools for Humanity sponsor H-1B visas?
Yes, Tools for Humanity sponsors H-1B visas for qualifying specialty occupation roles. Sponsorship is focused on technical positions where the role requires a directly related degree. Given the company's size and specialized focus, H-1B sponsorship is selective rather than broad, so applicants with niche expertise in areas like cryptography, biometric systems, or distributed systems are best positioned.
What other visa types does Tools for Humanity sponsor?
Beyond the H-1B, Tools for Humanity also sponsors the H-1B1 visa and TN visa categories. The H-1B1 visa is available exclusively to citizens of Singapore and Chile, while TN status applies to Canadian and Mexican nationals working in qualifying professional roles under the USMCA. These alternatives bypass the H-1B lottery, which can be a significant advantage for eligible candidates.
Which roles at Tools for Humanity are most likely to receive visa sponsorship?
Sponsorship activity at Tools for Humanity is concentrated in technical disciplines that directly support its biometric identity and blockchain infrastructure. Engineering, software development, applied cryptography, and data science roles are the most likely candidates. Non-technical functions such as marketing, operations, or general management are less commonly sponsored at companies with a focused technical headcount like this one.
How do I find open visa-sponsored jobs at Tools for Humanity?
Migrate Mate is the most direct way to find verified visa-sponsored openings at Tools for Humanity. The platform filters jobs by confirmed sponsorship history, so you can see current listings at the company without guessing whether sponsorship is actually available. This saves time compared to applying broadly and discovering late in the process that a role doesn't support visa candidates.
How do I approach the application timeline if I need H-1B sponsorship at Tools for Humanity?
The H-1B process runs on a fixed federal calendar. USCIS opens registration in early March, with a lottery typically conducted mid-March and petitions filed by April 1 for an October 1 start date. To give Tools for Humanity enough lead time, you should ideally be at the offer stage no later than late January or early February. Starting the process in the fall before your target start year gives you the best chance.
