About Peace Through Trade (PTT)
Peace Through Trade (PTT) is a regulation-first Layer-1 Proof-of-Work sustainable blockchain built to power real-world commerce. We are building infrastructure for people, governments, and institutions who want secure, transparent, and sustainable digital trade at global scale.
We have been recognized at the United Nations for our SDG leadership in advancing sustainable development. As our technology expands, we are looking for a sharp, builder-minded AI Engineer to help bring intelligence to the systems powering our mission.
Your Mission
You will design, build, and ship the AI that makes our ecosystem smarter, from the search and discovery powering our marketplace to the tools that help millions of people transact, trade, and participate in the global economy.
If you want your work to reach people who have been left out of the systems most of us take for granted, and you would rather build something that matters than optimize ad clicks, this role is designed for you.
What You'll Do
Design and deploy AI and machine learning systems across our products, including search, recommendations, and discovery.
Build and integrate large language model features into our marketplace and streaming app.
Develop tools that improve fraud detection, identity verification, and trust across the network.
Work closely with our product and blockchain teams to turn ideas into shipped features.
Optimize models for performance, cost, and scale across a global user base.
Help shape our AI architecture and the standards we build on as we grow.
Stay close to the frontier and bring the best of what's possible into real products.
What You Bring
3+ years building and deploying AI/ML systems in production, not just prototypes.
Strong command of Python and modern ML frameworks (PyTorch, TensorFlow, or similar).
Hands-on experience with large language models, including fine-tuning, RAG, and API integration.
Solid software engineering fundamentals and the ability to write clean, maintainable code.
Comfort working across the stack and collaborating with product, design, and blockchain teams.
A bias toward shipping, with the judgment to know when something is good enough and when it isn't.
Experience in fast-paced startup or tech environments is a strong plus.
Bonus: familiarity with blockchain, Web3, or building for emerging markets.
What We Offer
The chance to build AI for a globally recognized blockchain project with real-world impact.
A mission-driven team working at the intersection of technology, sustainability, and global trade.
Flexible remote work with a distributed international team.
A role where your work ships and reaches real people, not a backlog that never sees daylight.
If you want to build AI that helps bring the world into the economy, not just make a feed more addictive, we would love to meet you.

About Peace Through Trade (PTT)
A sustainable Layer-1 PoW blockchain powering peace, trade, and human progress. The Peace Through Trade (PTT) Blockchain is reshaping what it means to build with Proof of Work. Traditional blockchains use energy for security alone. PTT turns that energy into something more — a foundation for transparency, resilience, and real global trade. It is one of the world’s first AI-integrated Layer 1 Proof of Work systems, designed for sustainability, regulatory readiness, and accessibility. AI runs at the core of the network, continuously balancing loads, scaling capacity, predicting demand, and securing the system in real time. At the heart of the ecosystem is PTT Coin — a true utility gas token used to power every transaction, contract, and interaction. It is not for speculation. It is built for long-term utility and real-world use. The Infrastructure of Peace Through Trade Built under Singapore’s regulatory framework and interoperable with Ethereum, Polygon, and Binance Smart Chain, PTT connects traditional finance and decentralized systems. It supports a future where peace is powered through trade, not conflict. Developers can launch Layer 2 applications directly on PTT — from decentralized marketplaces to digital ID and trade finance tools — expanding its use across industries and borders. Key Highlights: • Layer 1 Proof of Work: decentralized, secure, and sustainable • AI-powered infrastructure: predictive scaling, autonomous stability, and continuous uptime • Energy-efficient design: up to 10,000× less power than Bitcoin at scale • Community mining: mine from your own computer, no ASICs required • Regulatory-ready: designed for KYC, AML, and ISO 20022 compatibility • Cross-chain utility: works with Ethereum, Polygon, and BNB networks Mining peace. Powering trade. Building permanence.
