Software Engineer Specialist - Data and AI

Description

Based in Barcelona, Spain, this role sits in the OneMesh Platform team of the company's Digital Data Team, which is moving the company toward being AI-first.

You will build the software and application layer that gives people across the company access to data and AI.

The team is creating next-generation data and AI platform services, including internal developer tools, data platform interfaces, AI-powered applications and governance tooling.

The products are deployed globally and aim to reach many patients. The company is a global biopharmaceutical business active in around 100 countries, focused on human health and vaccines.

Responsibilities

• Build full-stack applications and platform services across the OneMesh ecosystem with React, TypeScript, Node.js and Python (FastAPI), covering data platform UIs, internal developer tools, AI applications and operational dashboards.
• Design and maintain REST and GraphQL APIs that let internal teams find, manage and use data and AI capabilities, fitting cleanly into wider the company digital products.
• Implement LLM API usage, Retrieval-Augmented Generation (RAG), agent orchestration and evaluation frameworks, and turn them into reusable platform components other teams can adopt.
• Deploy and run cloud-native applications on OpenShift (Kubernetes) and AWS using GitOps practices, and write infrastructure-as-code in Terraform.
• Add security controls, audit logging, health checks, metrics dashboards and alerts so platform services stay reliable, easy to debug and operationally sound.
• Build and maintain CI/CD pipelines for fast, reliable, automated delivery, and take part in code reviews, architecture discussions and engineering standards.
• Work with data engineers, ML practitioners, product teams and business stakeholders to turn platform capabilities into polished, easy-to-use features.

Requirements

• A Bachelor's degree in Computer Science, Engineering or a related field, or equivalent experience.
• A proven record of building software products, backend systems, platform services or cloud-native applications.
• Being a strong plus: experience in internal platform teams, product engineering or data-driven application development.
• Strong command of Docker, Kubernetes/OpenShift, Python (FastAPI), Terraform, React, Node.js and TypeScript.
• Being a meaningful advantage: familiarity with AWS services (Lambda, API Gateway, ECS, RDS, Bedrock), Snowflake, PostgreSQL, Redis, message brokering, GitHub Actions CI/CD, and GenAI or LLM application patterns.
• A versatile, adaptable approach with strong ownership and a service-minded attitude. You can handle several products at once and do well in ambiguous, fast-moving settings.
• Excellent English communication, including explaining complex technical ideas to non-technical stakeholders, and enjoyment of working with diverse cross-functional teams.
