Role Summary

This role is a part of TRATON Group R&D, located in Södertälje, Sweden. Internal applicants from TRATON Group R&D are prioritized for this position. Candidates from the broader TRATON Group (including brands) are welcome to apply and may be reviewed based on business needs.

We are strengthening our capability within system modelling, simulation, and advanced control development, and are now looking for a Senior Development Engineer to take a leading role in shaping the next generation of after‑treatment functionality across Traton’s powertrain portfolio. Our group is responsible for the control and diagnostics of catalysts and particulate filters for all engine projects within the organization.

Job Responsibilities

In this role, you will drive the development of a complex system of understanding through modelling, and translate that into robust, efficient, and future‑proof functionality.

Your responsibilities include:

• Leading the development of mathematical and physically based models for after‑treatment components and complete systems.
• Developing and optimizing model‑based control and diagnostic functions using C‑based implementations.
• Driving improvements in methods and tools for model optimisation and validation, data analysis, and system characterization.
• Translating insights from system behavior into design decisions throughout the full development cycle—from concepts to legacy support.
• Interacting with test engineers to design and interpret experimental campaigns for model calibration and system verification.
• Supporting teams across the organization with system insights and modelling expertise.

You will work both on test benches and in vehicles to ensure that the functionality performs as intended under real‑world conditions.

Who You Are

We believe you bring several of the following strengths:

• You have experience working with the calibration of engines, catalysts, or particulate filters in engine test cells, ideally supported by strong modelling competence.
• You have experience and knowledge in software development. Coding in C and MATLAB/Simulink, as well as software testing, is an advantage.
• Ability to build and validate models that explain system behaviour and guide functional decisions.
• Broad experience in simulationdriven development, including datadriven and physicsinformed modelling.
• A background or strong interest in chemistry—particularly related to emissions, materials, or reaction kinetics—is appreciated but not mandatory
• A proactive and creative problemsolving mindset, with the ability to communicate complexity clearly to varied stakeholders.
• You have a Master’s degree in Engineering with a relevant specialization or someone with similar experience.
• You speak and write English. If you don't know Swedish you have a desire to learn it.

But the most important thing is that you have the right attitude and are willing to learn new things. We welcome applicants from all backgrounds – your unique experience and perspectives is valuable to us.
