About Multiply Teknik & IT

Multiply Teknik & IT is a Stockholm-based engineering and IT consultancy delivering high-value solutions to customers within the industrial and healthcare sectors. Our mission is to maximize customer value through innovation, technical excellence, and structured delivery.

We provide advanced solutions and services spanning industrial automation, business process consulting, cybersecurity training, cloud technologies, mechatronic design, and proprietary tools such as VisFlow—a leading platform for flow visualization, simulation, and analytics.

Role Overview

Multiply Teknik & IT is seeking a senior Industrial Automation Engineer with strong experience in automation project execution and project management. This role is well-suited for a technically hands-on professional who can both deep-dive into existing automation systems and take ownership of delivery, coordination, and technical leadership in customer projects.

You will work on-site with customer teams, primarily focusing on reverse engineering, debugging, restructuring, and optimizing existing production logic to ensure systems are lean, robust, maintainable, and compliant with best practices. In parallel, you will act as a technical driver in automation projects—supporting planning, coordination, and execution across stakeholders.

The role centers around Siemens TIA Portal, where you will analyze legacy systems, identify inefficiencies, and either refactor or rebuild solutions to meet modern automation and production requirements.

This is a 4-month contract with an immediate start. Freelancers and candidates seeking a short-term assignment are welcome to apply.
