Who are we? IOG, is a technology company focused on Blockchain research and development. We are renowned for our scientific approach to blockchain development, emphasizing peer-reviewed research and formal methods to ensure security, scalability, and sustainability. Our projects include decentralized finance (DeFi), governance, and identity management, aiming to advance the capabilities and adoption of blockchain technology globally.

By fueling creativity, innovation, and progress within our teams, our products and services are designed for people to be fearless, to be changemakers. What is Bitcoin DeFi: Bitcoin DeFi is about unlocking real utility for the world’s most trusted digital asset without ever compromising user control. For developers and innovators, this means finding a way to use Bitcoin in decentralized finance without forcing holders to hand their BTC to a third party. Until now, most attempts at Bitcoin DeFi have relied on “wrapped” tokens that essentially represent a promise – you send your BTC away and trust someone else to issue a proxy token on another chain. In all these custodial models, users effectively give up custody of their bitcoin to an intermediary in exchange for a tokenized representation. This status quo runs counter to Bitcoin’s core ethos of self-sovereignty and security. What the role involves: Do you thrive on solving complex problems, driving quality at scale, and ensuring world-class software delivery? At IOG, we’re looking for an experienced Senior Software Test Engineer to join our team.

Define and drive test strategy for high-impact projects. Design advanced test frameworks and create automation solutions for complex systems. Champion test automation at scale by building robust test suites and integrating them into CI/CD pipelines. Analyse and optimize test results, recommending improvements at both the code and process level. Troubleshoot and lead root cause analysis, ensuring rapid resolution of critical issues. Manage defects with rigor while mentoring others in QA best practices. Act as the escalation point for technical services and production incidents, driving preventative measures and long-term improvements. Who you are: 5+ years of testing experience with solid expertise in the QA lifecycle. Strong knowledge of testing methodologies and tools (ISTQB/ISEB certification a plus). Hands-on experience with automation frameworks, CI/CD, API testing, and distributed systems. Proficiency in at least one modern programming language (Rust, Python, Haskell, Java, Scala, C#, C++). Experience in performance and security testing (a big plus). Blockchain/Web3 experience Strong analytical, documentation, and communication skills with a real passion for quality. A higher degree in Computer Science, Engineering, Mathematics, Physics, or a related field.

About Story Story is a purpose-built Layer 1 blockchain designed specifically for intellectual property. With Story, creators can register IP on-chain and set usage terms in seconds—dramatically lowering the barrier of today’s complex and antiquated IP legal systems. For example, instead of requiring lawyers and months of negotiation, you could enforce terms like “you owe me 50% of commercial revenue if you use my IP” through the protocol itself. By making IP programmable, Story transforms intellectual property into a transparent, decentralized, global repository—where AI agents, developers, and humans alike can transact, license, and monetize IP with a simple API call. In February 2025, we launched the Story mainnet, and our native $IP token is now listed on major global exchanges. As we build out the next era of programmable IP infrastructure, we’re looking for a Senior Product Manager to drive protocol innovation and ecosystem adoption.
