This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Backend Engineer, Enterprise based in Spain.
This role sits at the core of a high-scale enterprise platform, where backend systems directly enable secure, reliable, and compliant experiences for some of the world's largest organizations. You will design and evolve distributed services that power mission-critical functionality used across enterprise customers globally. The work is highly cross-functional, involving close collaboration with product, security, legal, and infrastructure teams to translate complex requirements into robust technical solutions. You will take ownership of large-scale backend systems operating in production, with a strong focus on observability, reliability, and long-term scalability. Projects often span multiple teams and require breaking down ambiguous problems into clear, iterative delivery plans. This is an opportunity to shape foundational platform architecture in a fast-moving, AI-driven environment where engineering excellence is a priority.
Accountabilities:
Design, develop, and maintain distributed backend services and platform components supporting enterprise customers at scale
Own the end-to-end lifecycle of production systems, including deployment, monitoring, incident response, and continuous reliability improvements
Translate complex business, security, and regulatory requirements into scalable and maintainable technical solutions
Lead the decomposition of large, ambiguous initiatives into structured, iterative engineering deliverables across multiple teams
Build and enhance systems related to security, access control, data handling, multi-tenancy, and enterprise compliance requirements
Collaborate closely with cross-functional partners including product, infrastructure, security, and legal teams
Define and track system health metrics, leveraging observability tools to ensure performance, reliability, and scalability standards are met
Contribute to architectural decisions that ensure long-term platform evolution and support future enterprise growth
