Job description

When researching the impact of current and future radio network standards, realistic simulation tools are needed to make technically correct decisions. At Ericsson Research, we extensively use in-house simulator tools with varying levels of details for this purpose. To enable faster simulations for use cases that need less detailed models of radio-related layers, we constantly need to re-evaluate simulator models and produce new models with slightly less accuracy, but faster runtime.

What you will do

• With the help of coding agents, understand existing simulator models
• Propose simplified mathematical models of these features
• Implement the proposed models in the simulator
• Evaluate the accuracy and execution of the new models compared to existing models
• Document and present findings

The skills you bring

• You like to work in an environment where you co-operate closely with your team colleagues, together striving to fulfil common targets.
• You like to communicate with people and find it easy to explain your findings and knowledge to others.
• You have very strong analytical skills and are eager to find innovative solutions to problems.
• You should have a sound understanding of digital and wireless communications with an interest in algorithm development and testing.
• You have strong programming skills in Java, experience of working with AI coding agents, and excellent mathematical knowledge.
• You are an MSc student in electrical engineering, computer science or related fields.

Why join Ericsson?

At Ericsson, you´ll have an outstanding opportunity. The chance to use your skills and imagination to push the boundaries of what´s possible. To build solutions never seen before to some of the world’s toughest problems. You´ll be challenged, but you won’t be alone. You´ll be joining a team of diverse innovators, all driven to go beyond the status quo to craft what comes next.
