Company

NestAI is a European AI lab for defence delivering the adaptive operating system for modern battlefield operations. We develop adaptive intelligence for unmanned and command systems: AI that continuously learns from operational data and adapts to changing conditions.

NestOS is our open, modular and interoperable platform that enables this at scale and keeps capability evolution under sovereign European control. Founded in 2025 by Peter Sarlin, whose previous company Silo AI became Europe's largest AI acquisition, NestAI brings together over 150 engineers and scientists and partners with leading European defence forces and industry.

The Role

We are looking for a hands-on Cloud ML Engineer to join our team full-time either in Tampere or Helsinki, to bridge the gap between model development and production-grade deployment. In this role, you aren’t just training models; you are building the "industrial engine" that runs them.

In this position, we have two primary paths depending on your strengths and career interests: Internal Product R&D and Forward Deployed Engineering (FDE).

• Internal Product R&D: You will focus on building, scaling, and maintaining the core infrastructure and cloud-based applications that power our long-term product vision. In this path, your mission is to take our researchers' trained models and transform them into scalable, high-performance APIs and services, providing the tools, consistency, and infrastructure (from Cloud to On-Prem) that allow our AI capabilities to work reliably in the physical world.
  

• Forward Deployed Engineering (FDE): Embedded directly in our customer's development environment, FDE squads shorten the path from development to fielded capability, validating product capability where assumptions are tested against operational reality. This path is dynamic and highly impactful, where you will navigate shifting environments, collaborate with external stakeholders, and solve complex engineering challenges where adaptability is key.

Your Day-to-Day

• Architect and deploy inference services using frameworks like KServe, NVIDIA Triton, or Nuclio.

• Design and maintain ML pipelines and workflows to power our evolving ML Platform.

• Manage deployments within Kubernetes environments across diverse settings, from standard Cloud to specialized On-Premise servers.

• Take true ownership of ML Platform components, ensuring governance, traceability, and best practice workflows for all AI developers at NestAI.

What You Bring

• Proven experience in deploying ML/LLM models in production environments

• Strong proficiency in Kubernetes and cloud-native inference frameworks

• Solid backend engineering skills (Python or Typescript)

• Experience with workflow orchestration and a “DevOps mindset” for machine learning

• Growth mindset, that embodies a desire to develop and stay ahead of the curve in a fast-moving field.

• You have the drive to build something from the ground up and see it through to production.

• Excellent analytical and problem-solving skills with strong attention to detail.

• Ability to work collaboratively across domains and disciplines.

Why join NestAI

At NestAI, you’ll build meaningful, real-world technology as part of a world-class team of engineers, scientists, and experienced professionals. You’ll work on systems where reliability genuinely matters, contribute to Europe’s security and resilience, and solve problems that demand depth, trust, and craftsmanship.

If you want to build with purpose — and with leading experts in the field — you’ve come to the right place.
