Arbetsbeskrivning

Are you an experienced simulation engineer with a strong background in exhaust aftertreatment systems and catalyst modeling? Do you enjoy working with high-fidelity models that support real product development within the automotive industry? Then this could be an interesting opportunity for you. ALTEN is now looking for a  1D SIMULATION ENGINEER to support one of our clients within the automotive industry. In this role, you will contribute to model-based development of exhaust aftertreatment systems, supporting both software development and calibration activities. ABOUT THE ROLE As a 1D Simulation Engineer, you will work with the development, calibration, and validation of high-fidelity EATS models. The focus is on  GT-POWER AND SIMULINK, where you will build and maintain models representing catalyst systems and exhaust components under realistic operating conditions. You will integrate these models into a broader simulation environment used by software developers and calibration engineers, enabling concept evaluation, feature development, and virtual calibration. The role combines deep technical modeling work with close collaboration across system, software, calibration, and test teams. MAIN RESPONSIBILITIES Develop, maintain, and enhance 1D exhaust aftertreatment models in GT-POWER and Simulink Model catalyst systems such as DOC, DPF, SCR, ASC, mixers, sensors, and thermal components Calibrate and validate models using data from engine dyno, rig, and vehicle testing Perform parameter identification related to reaction kinetics, thermal behavior, soot loading, and regeneration Integrate models into a Simulink-based system simulation environment Support software and calibration teams with model-based analyses and simulations Participate in root-cause investigations and technical problem solving Document modeling and calibration methodologies YOUR PROFILE You are a structured and analytical engineer with strong domain knowledge in exhaust aftertreatment systems. You enjoy combining theory with real test data and are comfortable explaining complex technical concepts to different stakeholders. We see that you have: Master’s degree (PhD is a plus) in Mechanical Engineering, Chemical Engineering, Automotive Engineering, Applied Physics, or similar Solid experience in EATS simulation and catalyst systems (mandatory) Hands-on experience with GT-POWER and MATLAB/Simulink Strong understanding of catalytic chemistry and aftertreatment performance Knowledge of thermodynamics, fluid dynamics, heat transfer, and chemical kinetics Experience working with test data from engine or rig environments Very good communication skills in English Meritorious: Experience with alternative fuels (e.g. HVO, hydrogen) Experience with automation using MATLAB or Python Familiarity with version control systems (Git, SVN, or similar) Experience from heavy-duty engine or emissions development ABOUT ALTEN Every employee is equally valuable in the success of ALTEN! We believe in growing together by offering opportunities, development and togetherness. ALTEN operates in several different industries, having a wide variety of assignments, coaching managers and training through ALTEN Academy, which means that it will always be possible to develop at ALTEN. Your wishes will guide your way forward. As a consultant, you will get the genuine team feeling at your assignment but also a wonderful togetherness at ALTEN. Through our different internal networks, such as Women@ALTEN and ALTEN Sports you will get the opportunity to drive topics and activities that are close to your heart. At ALTEN, we think it's important to have a balance between work and spare time, which is why we offer three extra days off a year. We have a collective agreement and offer benefits like pension, insurances and wellness grants.
