About envelio

envelio builds software for intelligent electricity grids, with the goal of supporting the energy transition worldwide. The company has over 150 employees from more than 20 nationalities and describes its culture as down-to-earth, with a love for coffee, mate, geek humor, and emojis. The role is remote within Germany and full-time.

About the role

This is a senior backend engineering position in the Core Team, focused on system infrastructure and architecture, data modeling, and graph functionality. You will help develop GridHub, the core component that feeds all applications, and design robust interfaces and generalized solutions for complex requirements. The work directly affects users, the organization, and technical procedures.

A typical day

A typical day may involve designing and implementing backend components for GridHub, reviewing code, and collaborating with other engineers on system architecture and data modeling. You might work on cross-application workflows to ensure data integrity for planning and live applications. The exact daily routine is not described in the job details, so ask about team rituals and workflows during the interview.

Who envelio is looking for

• Experienced backend engineer with a strong background in system infrastructure and architecture.
• Skilled in data modeling and graph functionality, with the ability to design robust interfaces and generalized solutions for complex requirements.
• Comfortable developing and extending cross-application workflows that ensure data integrity for planning and live applications.
• Able to take ownership of core functionality for a digital twin and work in a senior capacity within an experienced development team.

Tips for this application

• Highlight specific experience with system infrastructure, architecture, data modeling, and graph functionality, since these are the stated focus areas of the Core Team.
• Mention any work on core components or platforms that feed multiple applications, similar to GridHub.
• Show familiarity with designing robust interfaces and generalized solutions for complex requirements, using concrete examples.
• Address cross-application workflows and data integrity for planning and live applications in your materials.
• Since the job description is in German, consider whether to submit your application in German or English, and check the company's preferred language if unsure.

What to cover in your cover letter

['Your experience with system infrastructure and architecture in a backend engineering role.', 'Concrete examples of data modeling and graph functionality you have implemented.', 'How you have designed robust interfaces and generalized solutions for complex requirements.', 'Your approach to developing cross-application workflows that maintain data integrity for planning and live applications.']

Research before applying

• Read about envelio's GridHub and how it serves as the core component for their applications.
• Look into envelio's mission around intelligent grids for the energy transition and what that means for backend engineering.
• Check the company's engineering blog or tech stack if available, to understand their infrastructure and data modeling practices.
• Find out how the Core Team interacts with other teams and what the development process looks like.

Likely interview topics

Based on the job description, expect questions about:

• How you would design robust interfaces and generalized solutions for a core component like GridHub.
• Your experience with data modeling and graph functionality, including specific tools or approaches.
• How you ensure data integrity in cross-application workflows for planning and live applications.
• Your understanding of system infrastructure and architecture in a backend context.
• How you handle complex requirements and translate them into maintainable backend code.

Common mistakes to avoid

• Submitting a generic backend application without referencing system infrastructure, architecture, data modeling, or graph functionality.
• Ignoring the Core Team's focus on GridHub and cross-application workflows in your materials.
• Failing to address the senior level of the role or provide examples of owning core functionality.
