Descripción del empleo

Are you ready to take your skills to the next level in a company that values innovation, precision, and continuous improvement?

With over 3,500 employees and headquarters in Germany, BHS Corrugated operates in more than 20 countries and is a global leader in the corrugated cardboard industry. We offer complete solutions across the full product lifecycle—from mechanical and electrical design to production, installation, predictive maintenance, and digital services. Our projects involve high-tech components such as corrugating rolls, custom-built machinery, full production lines, Industry 4.0 applications, and inline digital printing.

Our vision is focused on the future: we will integrate AI and Automation into our technologies and user experiences around the world!

Since 2024 we are expanding to Spain. If you're based in Spain and looking for a new professional challenge in a tech-driven, international environment, this is your opportunity to join our new team in Málaga – BHS Spain. Contribute to cutting-edge projects with global impact—and grow with a company that is shaping the future of industrial manufacturing.

What You’ll Do

• Design and develop plant-level software and MES/SCADA systems for industrial manufacturing environments.
• Build robust applications using C#, .NET, and industrial communication protocols like OPC-UA, Modbus, and MQTT.
• Integrate REST APIs and industrial data sources to connect factory-floor systems with higher-level platforms.
• Work closely with engineering teams in Germany and China on cross-border automation projects.
• Contribute to clean, maintainable, and automated codebases following software best practices.
• Explore and apply AI-assisted development tools to boost productivity and innovation Using tools like Copilot or Claude)
• Travel to Germany periodically to collaborate on-site with colleagues and visit production facilities.

What You Bring

This is a software engineering role, not an automation engineering role. You won't be programming PLCs or configuring SCADA panels — you'll be building the C#/.NET applications that connect to them. We're looking for developers who write clean, testable, maintainable code AND understand why industrial environments impose different constraints than typical enterprise software.

Our software runs on corrugator lines worldwide, some for over a decade. You'll work with both greenfield projects and existing systems — modernizing legacy code, ensuring backward compatibility, and making thoughtful architectural decisions that will hold up over long product lifecycles. If you enjoy the challenge of evolving a living codebase rather than only starting from scratch, you'll thrive here.

Must have:

• 3–5 years of professional C# / .NET development (not scripting, not configuration — actual software engineering)
• Solid understanding of object-oriented design, clean architecture, and software lifecycle management
• Experience with Git, CI/CD, automated testing, and modern development workflows
• Willingness and ability to work with legacy codebases — refactoring, modernizing, and maintaining long-lived systems
• Fluent English (written and spoken)

Preferred:

• Experience building software that interfaces with physical systems — industrial machines, PLCs, sensors, or IoT devices
• Familiarity with industrial communication protocols (OPC-UA, Modbus, MQTT) or willingness to learn them quickly
• Understanding of what makes industrial software different: long lifecycles, backward compatibility, reliability requirements, deployment to plant environments rather than cloud
• Exposure to SCADA, MES, HMI, or similar plant-level systems — as a developer, not an operator/configurator

What we offer

• Modern offices with a vibrant and collaborative environment.
• Flexible work schedules and models.
• Opportunities for career growth and continuous learning.
• International trips to Germany to connect with colleagues and learn from real production and customer sites.
• Flat hierarchy and a friendly, supportive team.
• After the probation period: private insurance with Sanitas and flexible benefits (restaurants, public transport, and kindergartens).
