Role overview
Our client builds some of the world's most powerful electric motorcycles — championship-winning bikes engineered to outperform traditional combustion engines. Based in Barcelona and growing fast, they're a category leader on a mission to make premium motorcycles more sustainable, cutting plastic and CO2 pollution without compromising on performance, design, or the emotional experience riders expect. You'd be helping build the backend and AI systems powering this next stage of growth by helping build the web platform that powers the business end-to-end — a highly-integrated environment delivering consistent data and services across all systems.
Responsibilities
- Act as the main developer for the AI-based solutions, supporting AI engineers with operationalization of python-based AI tools into node.js and python backends.

- Design, develop and maintain web services and APIs in Python/Node.js (or other specialized stacks).
- Enforce coding standards for clean, concise, stable, and extensible code.
- Troubleshoot, debug, and resolve production issues with urgency.
- Collaborate cross-functionally—with AI team, product owners, front-end teams, QA, DevOps, and external partners—to meet business objectives.
- Make high-level architecture decisions, balancing scalability, performance, and maintainability.
- Stay current on industry trends, evaluate new tools, and recommend product-level improvements.
- Serve as a mentor and role model for new and existing team members.
- Own and prioritize your technical backlog, ensuring transparency and alignment.

- Experience creating and maintaining production-grade RESTful APIs; strong grasp of versioning, auth, rate limiting and pagination patterns.
- Proven expertise in scalable architecture patterns (microservices, event-driven systems, CQRS), containerization (Docker/Kubernetes) and CI/CD pipelines.
- Solid SQL skills (schema design, indexing, migrations, performance tuning) on PostgreSQL or MySQL.
- Strong problem-solving skills.
- Proficient in English.
- Growth mindset: open to feedback, committed to continuous learning, documentation and knowledge sharing.
