• Build and own backend systems • Design and build APIs, services, Ethereum data pipelines and indexers, staking and validator infrastructure integrations, and monitoring and operational tooling. • Own system design end-to-end: architecture, implementation, testing, deployment, and observability. • Work across the Ethereum stack, integrating with both execution layer and consensus layer clients. • Contribute to Liquid Collective alongside other staking and blockchain infrastructure projects across Galaxy. • Set and maintain the bar on API design, testing strategies for distributed systems, reliability and fault tolerance, and security and key management practices. • Operate in a spec-first development environment — translate product and protocol requirements into clear technical specs before building. • Leverage AI-assisted development workflows (e.g. Claude Code) and work with emerging paradigms like MCP (Model Context Protocol) and agent-based tooling. • Work cross-functionally with protocol, product, and infrastructure teams. • Mentor engineers through code review, design feedback, and raising the overall quality of what the team ships. • Contribute to how the team evolves its practices — not just executing within the current system, but improving it. • Embrace and champion the thoughtful adoption of AI to improve team performance and business outcomes. • Leverage AI tools (e.g., generative AI, automation platforms, data copilots) to improve productivity, decision-making, and output quality in your day-to-day work.

• Developing and maintaining all server-side network components. • Ensuring optimal performance of the central database and responsiveness to front-end requests. • Collaborating with front-end developers on the integration of elements. • Designing customer-facing UI and back-end services for various business processes. • Developing high-performance applications by writing testable, reusable, and efficient code. • Implementing effective security protocols, data protection measures, and storage solutions. • Running diagnostic tests, repairing defects, and providing technical support. • Documenting Node.js processes, including database schemas, as well as preparing reports. • Recommending and implementing improvements to processes and technologies. • Keeping informed of advancements in the field of Node.js development.

• Design, build, and govern cloud-based data platforms that turn heterogeneous, multi-country life-sciences data into trusted, reusable data products. • The role spans clinical trial data, real-world data (RWD), and omics — harmonising these into standardised, regulatory-grade, analysis-ready assets. • Combines hands-on engineering on Azure and Databricks with technical leadership of a multidisciplinary team.

• Diseñar, desarrollar y mantener funcionalidades end-to-end siguiendo especificaciones funcionales y técnicas. • Diseñar y exponer APIs RESTful. • Escribir pruebas unitarias e integración. • Participar en code reviews y mantener estándares de calidad. • Contribuir a documentación técnica. • Diseñar y desarrollar servicios backend escalables.
