Software Developer - Control Systems & Heat Pumps

Description

You will help design, build and tune intelligent control and regulation algorithms for modern heat pumps, which support the shift to cleaner energy.

The role sits in a cross-functional team developing the next generation of energy-efficient heating and cooling products.

The team is based in Tranås, Sweden, a town on Lake Sommen, at a site of more than 600 people who make and develop heating solutions.

The team works in an international, agile setup alongside experts in software, electronics, HMI, hydraulics and thermodynamics.

Responsibilities

• Develop control and regulation functions for the latest heat pumps, pushing new algorithms for efficient, resource-saving heating and cooling.
• Guide software functions from requirements and concept simulation through implementation and verification at the MIL, SIL and HIL levels.
• Design and refine model-based software in Matlab/Simulink for closed-loop control of thermodynamic and hydraulic systems.
• Write embedded software modules in text-based languages such as C/C++, using current engineering and AI-assisted tools.
• Commission and test application software on advanced heat pump test benches, supporting rapid prototyping and validation on real systems.

Requirements

• A bachelor's or master's degree in mechatronics, control systems, mechanical engineering, computer science, process engineering or a related technical field, or an equivalent practical engineering background.
• A solid grounding in control engineering, mechatronic systems or thermodynamic processes.
• Practical software development experience, either in model-based development with Matlab/Simulink or in text-based embedded programming with C/C++.
• Working familiarity with software testing or simulation concepts such as MIL, SIL or HIL.
• Working proficiency in English, written and spoken, at business level.
• A solution-oriented approach, genuine interest in clean energy technology, and a willingness to learn and grow in an international team.
• Several years of hands-on industry experience in embedded software or controls engineering.
• Knowledge of HVAC systems, refrigeration cycles or hydraulic systems.
• Experience with bus protocols and communication interfaces such as CAN, LIN, Modbus or MQTT.
• Familiarity with agile practices such as Scrum or Kanban, and with CI/CD tooling such as Git, Jira or Jenkins.

Conditions

Flexible hours and hybrid work options are available.

The role is based at the company's site in Tranås, Sweden.

Benefits

• Work that contributes to decarbonization and climate technology.
• Competitive salary packages, collective agreements with unions and an occupational pension.
• A wellness contribution, smart work arrangements, and on-site gym and yoga classes.
• Access to up-to-date development tools, AI tooling, and technical and language training.
• Laboratory and test bench facilities in an open, international team.
• Support for personal goals such as career development, family time and hobbies.
