Jobbeschreibung

1KOMMA5°

We are looking for you as an addition to our tech team in Berlin. 1KOMMA5° is building Germany's largest one-stop-shop for sale, installation, and services related to solar, heat pumps, electricity, and charging infrastructure. Be a part of our mission!

Your mission

In tech, we have two main work streams:

• Heartbeat: Building a virtual power plant leveraging our energy manager “Heartbeat” and evolving the customer experience app around this.
• Operating System for installation companies: Digitisation of operations and processes from ground operations to rooftop installations.

As an IoT Software Engineer, you will play a crucial role in integrating OEM devices, such as PV inverters, batteries, charging infrastructure, and heat pumps, into our cutting-edge heartbeat platform. Your role involves implementing communication protocols, developing embedded software modules on IoT gateway and controller devices, and conducting testing of our energy management system in our lab in Berlin. You will also be providing expert-level support for both internal and external stakeholders. Collaborating with cross-functional teams, you'll contribute to the entire product lifecycle.

Key responsibilities include but are not limited to:

• Integrate PV inverters, batteries, charging infrastructure, and heat pumps into our heartbeat platform.
• Ensure seamless communication and interoperability between different OEM devices.
• Implement communication protocols such as Modbus TCP, OCPP, MQTT, EEbus.
• Develop, deploy, and maintain embedded software modules on IoT gateway and controller devices using Go programming.
• Maintain and customize embedded Linux distributions using Yocto for IoT gateway devices.
• Conduct testing of our energy management system in our lab in Berlin.
• Collaborate with cross-functional teams to ensure software meets performance and reliability standards.
• Provide expert-level support to both internal and external stakeholders.

Your profile

You have:

• Bachelor's or Master's degree in Computer Science, Electrical/Electronics Engineering, Control Engineering, or related field.
• Proven experience in IoT development and integration, with a focus on integrating diverse OEM devices.
• Hands-on experience in the development of embedded software modules for IoT devices.
• Experience with IoT development using Go programming is highly preferred.
• Experience with Linux build systems, particularly Yocto, is strongly favored and will provide a competitive edge for this role.
• Proficiency in communication protocols such as Modbus TCP, OCPP, and MQTT.
• Understanding of energy management systems and related technologies.
• Familiarity with DevOps practices and tools, including continuous integration and deployment (CI/CD) pipelines.
• Excellent troubleshooting and problem-solving skills.
• Experience quickly finding your way around in cross-functional teams in a fast-paced, interdisciplinary working environment.
• An agile and result-oriented mindset and you consider yourself a team player.
• Very good knowledge of spoken and written English; German is a plus.

Bonus points for:

• Experience in model-based development with Matlab/Simulink.
• Familiarity with cloud platforms (ideally Google Cloud) and their integration in IoT solutions.
• Experience in implementing APIs for complex systems.
• Previous experience in providing support to international stakeholders.
• Certifications related to IoT and energy management.
• Interest in the climate tech industry.

Even if you do not meet all the listed requirements, we still encourage you to apply and reach out to us. We value diverse experiences and believe that the right candidate may bring unique skills and perspectives to the role.

We are an ambitious and dynamic company with a talented team. We require our engineers to be imaginative, enthusiastic, and willing to tackle new challenges as we strive to provide everyone with renewable energy technologies.

Benefits

• Contribute to a dynamic and highly motivated team with people who have proven that they can make things happen and move companies forward.
• With your work, you accelerate the "energy and mobility transition" and make a concrete contribution to the sustainable transformation of our energy infrastructure.
• You move in flat hierarchies and have direct contact with the managing directors as well as short decision-making paths.
• Work with and learn from other skilled engineers and join conferences and exciting meetups.
• You can work remotely (Germany-wide), with offices in Berlin, Hamburg, and Munich.
• See the direct impact of your work on a rapid-scaling user base.
• Create a healthy balance alongside your work and enjoy all the benefits of the EGYM Wellpass.
