About the Product:
Our client is a product technology company developing a cloud-native platform that enables organizations to build, integrate, and operate secure applications leveraging blockchain and distributed ledger technologies. The platform provides scalable backend services, APIs, and infrastructure components designed for high-performance, production-grade environments.
The engineering team focuses on building resilient backend systems, distributed architectures, and blockchain-enabled services while addressing challenges related to scalability, reliability, performance, and security. Engineers collaborate closely across product, platform, and infrastructure teams to deliver robust software solutions used in mission-critical environments.
About the Role:
As a Senior Full Stack Engineer with a strong backend focus, you will design, develop, and maintain scalable backend services while also contributing to modern web applications where needed. You’ll work with microservices, APIs, asynchronous architectures, blockchain integrations, and React-based frontend components, collaborating closely with cross-functional engineering teams.
This role offers end-to-end ownership of product features from architecture and implementation through deployment, monitoring, and continuous improvement, with the primary focus on backend services.
Key Responsibilities: * Design and build scalable backend services supporting blockchain-enabled applications and distributed systems. * Contribute to frontend features and modern React-based applications when required, ensuring a seamless end-to-end user experience. * Develop and maintain backend services, APIs, and platform components throughout the software lifecycle. * Integrate backend services with blockchain networks, third-party platforms, and external infrastructure. * Evaluate emerging blockchain technologies and architectural approaches to improve platform capabilities. * Optimize production systems for scalability, reliability, security, and performance. * Collaborate with product, platform, infrastructure, and security teams to deliver production-ready solutions. * Take ownership of features from design through deployment and ongoing optimization.
Required Competence and Skills: * 7+ years of professional experience as a Full Stack or Backend Engineer. * Strong commercial experience with Node.js, TypeScript, and React. * Experience designing scalable backend services, APIs, and production-grade microservices. * Solid understanding of distributed architectures, asynchronous communication, and event-driven systems. * Commercial experience working with multiple blockchain ecosystems, including EVM-compatible chains, as well as non-EVM chains * Good understanding of blockchain fundamentals, transaction processing, smart contracts, and decentralized architectures. * Strong understanding of secure software design and building reliable production systems. * Experience using AI-assisted development tools (Claude Code, Cursor, GitHub Copilot, or similar) as part of the engineering workflow. * Bachelor’s degree in Computer Science or a related technical field (or equivalent practical experience). * Proven ability to deliver software from design through production deployment.
Nice to Have: * Experience building products in high-scale distributed platforms, fintech, or cloud-native products. * Experience with cloud-native infrastructure, containers, and Kubernetes.
