Principal Optimization Engineer

Join Carrier’s Computational Engineering team within the Systems & Controls Center of Excellence in Lund, Sweden and help shape the future of HVAC innovation.

We develop advanced model-based methods, optimization algorithms, and ML-enabled tools that power smarter product design, improved system performance, and efficient real-world operation. Our work directly impacts global products by turning complex engineering challenges into scalable, data-driven solutions.

You’ll collaborate with international product teams, research institutions, and cross-functional experts to bring cutting-edge optimization and control strategies into real-world applications.

Your key responsibilities will be the following

• Design and deploy optimization methods and tools for thermo-fluid systems (chillers, heat pumps, hydronic systems)
• Translate business and engineering needs into mathematical models and decision-making workflows
• Develop and implement optimization-based control strategies (e.g., MPC, real-time optimization)
• Partner with global product teams to embed advanced tools into product development and operation
• Ensure robust, scalable approaches using non-linear and mixed-integer optimization techniques
• Drive adoption of ML/surrogate models in optimization workflows
• Collaborate across modeling, controls, and platform teams to deliver end-to-end solutions
• Mentor engineers, support training initiatives, and contribute to technology roadmap development
