Our Tracking-as-a-Service (TaaS) platform combines a proprietary IoT mesh network, telemetry, and advanced analytics to deliver real-time visibility over physical assets --- track any asset, anywhere --- with no gates, readers, or fixed infrastructure.
Born inside IFCO , the integral market leader in reusable packaging containers for fresh food, TRLLN is now a standalone subsidiary of IFCO : engineered for the world's largest reusable-asset network --- 400 million assets across 50+ countries --- and combining that proven, industrial scale with the agility and focus of a tech company, from our Barcelona HQ.
As a Senior Site Reliability Engineer at TRLLN , you'll join the product engineering team that builds and runs the core of our platform : the backend and infrastructure that ingest, process, and serve high-volume IoT telemetry in near real time, on a multi-tenant, cloud-native architecture on Google Cloud --- GKE, Cloud Run, Managed Kafka, Pub/Sub, AlloyDB and BigQuery, all managed with Terraform.
Today reliability is everyone's job and nobody's specialty:



the team has strong software engineering foundations, an observability stack we are actively maturing, and availability commitments to customers that we want to back with real SLOs, alerting and runbooks . Security is a big part of this role. The platform goes through external security assessments and is preparing for the EU Cyber Resilience Act; the operational side of that --- cloud security posture, vulnerability and supply-chain management, incident readiness, business continuity --- will sit with you.
TRLLN is a startup-like environment backed by a global enterprise : we move fast, iterate with purpose, and care deeply about doing things right, always balancing pragmatism, speed and quality. Strong analytical and problem-solving skills, with a focus on delivery and quality.
Able to explain complex systems and trade-offs clearly, both verbally and in writing.
Proven experience operating high-volume / high-traf
