Our partner is looking for a Senior Backend Engineer, AI Orchestration based in Spain. Join a highly technical engineering team focused on building the infrastructure that powers reliable AI-driven workflow orchestration. In this role, you'll develop the core execution engine that enables AI agents and large language model workflows to operate efficiently, securely, and at scale. You'll work on backend systems where reliability, observability, and performance are critical, collaborating closely with product and engineering teams to transform complex AI use cases into reusable platform capabilities. This is an excellent opportunity for an experienced backend engineer with a passion for distributed systems and production-grade AI infrastructure. If you enjoy solving challenging technical problems and building foundational technology that enables next-generation AI applications, this role offers significant ownership and impact. Accountabilities Design and develop core execution primitives that enable reliable AI workflow orchestration within the platform's backend engine. Build, maintain, and enhance integrations with large language model providers and AI agent frameworks. Collaborate with product and engineering teams to transform real-world AI use cases into reusable orchestration patterns and blueprints. Ensure AI workflow executions are fully observable, traceable, and easy to debug through robust monitoring and diagnostics capabilities. Improve the reliability, scalability, and fault tolerance of AI execution pipelines by implementing retry strategies, state management, branching logic, and failure recovery mechanisms. Contribute to backend architecture decisions and continuously improve platform performance and maintainability. Stay informed about emerging AI orchestration technologies and recommend improvements to enhance platform capabilities. ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Do TypeScript without TypeScript](https://www.wearedevelopers.com/videos/327-do-typescript-without-typescript) - [Understanding Kubernetes in a visual way](https://www.wearedevelopers.com/videos/100085-understanding-kubernetes-in-a-visual-way) - [Agentic AI Systems for Critical Workloads](https://www.wearedevelopers.com/videos/1592-agentic-ai-systems-for-critical-workloads) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) ## Related Articles - [What is Agentic Programming and Why Should Developers Care?](https://www.wearedevelopers.com/magazine/625-what-is-agentic-programming-and-why-should-developers-care) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [From Prototype to Production: Build AI Agents with This Free 4-Course Learning Path](https://www.wearedevelopers.com/magazine/655-from-prototype-to-production-build-ai-agents-with-this-free-4-course-learning-path) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [What is Software Engineering in the Age of AI?](https://www.wearedevelopers.com/magazine/640-what-is-software-engineering-in-the-age-of-ai)
