Are you passionate about building modern web applications and curious about how things work under the hood of blockchain systems? Join our team and help us develop tools that make interacting with on-chain data and smart contracts more accessible and transparent. We’re looking for a FullStack Developer to help bring them to life! What project you’ll be working on? You may join one of our blockchain projects, such as building tools around the Stellar / Soroban ecosystem, including a smart contract block explorer. Your work will focus on making on-chain data more accessible and understandable - helping developers and users explore transactions, contracts, and blockchain activity in a clear and meaningful way. We don’t expect you to have experience with these particular technologies, as these are quite niche. What we do expect is that you’re eager to learn and explore. At Rumble Fish, we work on a variety of projects across blockchain, cloud, and AI, so depending on the project, you may also have the opportunity to explore different technologies and domains over time. If you're excited about building real products, working with modern technologies, and growing your skills in the Web3 space - let’s talk!
