Nalanda is a leading Spanish multinational dedicated to bridging the gap between large companies and their suppliers through an innovative digital platform. We specialize in coordinating activities between contractors and their suppliers, minimizing costs, time, and risks, while fostering transparent and effective business relationships.
We are a dynamic, forward-thinking company committed to building an inclusive workplace where talent thrives. At Nalanda, we believe that the development of people drives organizational success. We are also part of Once For All, an international group with a presence in the UK, France, Latin America, and more than 1,000 people working on digital solutions for supply chain management and regulatory compliance.
We're looking for a Senior Full Stack Engineer with a T-shaped profile: deep backend expertise in Java/Spring Boot microservices and solid TypeScript/SDK engineering capability on the frontend side.
This is not a traditional web app frontend role. The "frontend" work here is a published TypeScript SDK — library bundling, npm packaging,



and API ergonomics for third-party consumers. If you've built or maintained a JS/TS library and know what dual ESM/CJS output means, you'll feel at home.
You'll own complex features end-to-end across the AIV platform — from event-driven backend services through to the SDK that surfaces document data to consuming applications — and contribute to architectural decisions that span the full system.

Backend — your depth
• Design, build, and maintain backend services and APIs using Java 21 and Spring Boot 3.x (Web, Data JPA, Validation, Actuator).
• Build and maintain Kafka producers and consumers on AWS MSK with IAM auth.
• Own database schema design and migrations in PostgreSQL using Liquibase.
• Deploy and operate containerized services on AWS ECS/Fargate, working with S3, SQS, and IAM in a Terraform-provisioned infrastructure.
• SDK & frontend — your second arm
• Develop and maintain the platform'
