Lead AI Platform Engineer (m/f/d)

About the role

T-Systems Iberia is looking for a Lead AI Platform Engineer to design, build and operate a scalable, production-grade platform for deploying autonomous AI agents, including model serving, tool-calling and state management. The role sits within the AI Foundation Services team, which builds the platform infrastructure powering AI inference at scale, and combines software engineering, distributed systems and AI infrastructure.

Key responsibilities

• Design and own the core platform that builds, deploys and runs autonomous AI agents.
• Build high-throughput, low-latency inference services on GPU/TPU clusters and implement autoscaling with Kubernetes and Knative.
• Create CI/CD and MLOps pipelines for model versioning, canary releases and rollback.
• Define SLO/SLI, set up monitoring (Prometheus, OpenTelemetry) and lead incident response.
• Implement security controls such as IAM, sandboxed execution and data-residency policies.
• Deliver developer-friendly SDKs, CLI tools and documentation for internal teams and external partners.
• Mentor junior engineers and champion best-practice code standards.

Required profile

• 7+ years of software engineering and 4+ years building large-scale distributed systems.
• Hands-on experience with model serving frameworks and GPU/TPU workloads.
• Solid knowledge of LLM concepts, retrieval-augmented generation and tool-use APIs.
• Nice to have: Ph.D. or M.S. in CS or a related field, serverless runtimes, vector databases or agent frameworks, and open-source contributions in AI/ML infrastructure.

Required skills

• Proficiency in Go or Rust and Python; strong Kubernetes, Docker and Helm experience.
• Event streaming (Kafka/Pulsar) and infrastructure-as-code (Terraform/Pulumi).
• Observability (Prometheus, Grafana, OpenTelemetry) and security (IAM, Vault).

What we offer

• Hybrid work model and flexible working hours.
• Customized training via Coursera, weekly language classes and international mentoring sessions.
• Flexible compensation plan covering health insurance, meal vouchers, childcare and transport.
• 26+ working days of vacation per year and free access to specialist services.
