Senior DevOps Engineer

What if your next role let you shape the future of AI—and do it with empathy, responsibility, and real-world impact? One of the biggest challenges and opportunities with artificial intelligence is around the data used to train AI models, and how to do that responsibly and ethically whilst governing data protection, applying AI regulations, democratizing knowledge, and balancing individual rights with societal benefits.
As a Senior DevOps Infrastructure Engineer in Project Hafnia, you will be responsible for designing, building, deploying, and optimizing our scalable container orchestration architecture. This includes working with orchestration platforms to create hybrid environments combining native cloud services with horizontally scalable clusters. Your expertise in resource optimization, multi-node and multi-GPU management, and high-performance computing will be critical in delivering a robust AI infrastructure. You will collaborate closely with cross-functional teams to ensure best practices, compliance, and operational excellence.
You will join our innovative and entrepreneurial development team at Milestone, a global leader in data-driven video management solutions. Our mission is to build a suite of services centered around a responsible data library, leveraging compliant, high-quality, ethically sourced video data. We follow a long-term strategy, continuously scrutinize emerging AI, and adhere to our ethical tech and responsible technology agenda.
