AI Algorithm Engineer

Company Description

NestAI is Europe’s fastest-growing physical AI lab. We build open, sovereign, and reliable autonomous systems and AI-enabled command capabilities for real-world operations — technology designed for environments where reliability isn’t optional.

Our work strengthens Europe’s ability to remain safe, resilient, and sovereign. At the core of NestAI’s vision is an open, modular and interoperable AI command centre. To this end, it integrates data from multiple sources — including UAV sensors, edge devices and situational intelligence platforms — and uses it to automate operations and decision support in order to drive rapid and efficient action in critical environments.

Rooted in Nordic engineering heritage, we focus on openness, reliability, and systems that earn trust through performance. We work with intent, iterate fast, and build technology that protects what matters most.

Role Description

We are looking for an AI Algorithm Engineer to join the AI / Algorithms Chapter at NestAI. You will design the core logic and decision-making frameworks that allow physical AI to navigate complex environments and execute tasks with precision. This is a high-math, high-logic role where you will bridge the gap between abstract control theory and high-performance execution on the edge.

You’ll work closely with our multidisciplinary teams — including embedded, cloud, and hardware engineers — to turn cutting-edge research into real, high-performance systems.

You will be responsible for developing algorithms, training and optimizing models, building scalable data pipelines, and integrating AI solutions into production environments.

Day-to-day Responsibilities:

• Decision Logic & Control: Designing and implementing algorithms for sequential decision-making, path planning, or autonomous behavior.
• Model Optimization: Developing custom training routines and loss functions to improve model robustness in non-deterministic physical environments.
• Edge Performance: Collaborating with embedded teams to optimize non-vision models (e.g., RL policies, signal processing) for low-latency execution on hardware like NVIDIA Jetson.
• Simulation & Validation: Creating high-fidelity simulations to train and stress-test algorithms before they ever touch physical hardware.
• Cross-Domain Integration: Working with the CV team to ingest perception data and the Hardware team to output precise physical commands.
• Applied Research: Adapting state-of-the-art papers in RL, GNNs, or Control Systems into production-ready code.

Qualifications:

• ML Theory: Strong skills in machine learning theory and deep learning model development.
• Technical Stack: Proficiency in Python and experience with frameworks such as PyTorch or TensorFlow.
• Deployment Knowledge: Understanding of data processing pipelines, model deployment, and performance optimization.
• Engineering Standards: Experience with version control (Git), CI/CD, and Linux-based environments.
• Environment Familiarity: Familiarity with modern computation or edge environments (e.g., GCP, AWS, Azure, SLURM, NVIDIA Jetson).
• Problem Solving: Excellent analytical skills with strong attention to detail and a collaborative mindset.

Preferred Extras:

• Algorithm Specialization: Experience in Reinforcement Learning (RL), Control Systems, or Sequential Decision Making.
• Edge Use Cases: Understanding the unique constraints of physical AI (e.g., power consumption, latency, and "disconnected" environments).
• Industry Experience: Previous experience working within or for DefSec (Defense & Security) companies.
• Hardware-Aware AI: Experience with real-time inference optimization (e.g., TensorRT, quantization, or pruning) for hardware-constrained systems.
• Low-level Skills: Proficiency in C++ or experience with custom CUDA kernels.

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.
