6. Key Responsibilities

As a Solutions Architect, you are responsible for the end-to-end design of solutions that enable our workforce to operate more effectively. You will work closely with product managers to define requirements and with engineering teams to ensure those requirements are translated into high-performance, cost-effective code and infrastructure.

A significant portion of your time will involve evaluating existing systems, identifying bottlenecks, and proposing modernizations that align with our long-term digital strategy. You will be expected to lead design reviews, document architectural decisions, and participate in the hands-on tuning of critical performance paths.

7. Role Requirements & Qualifications

We seek candidates who bring a blend of deep technical expertise and a pragmatic mindset.

  • Must-have skills: Profound experience in Azure cloud architecture, strong command of enterprise software integration (e.g., Dynamics 365), and a proven track record in system design and capacity planning.
  • Nice-to-have skills: Experience within the energy or utilities sector, familiarity with modern DevOps practices, and prior experience leading technical migrations.
  • Soft skills: Exceptional ability to translate technical jargon for executive stakeholders, conflict resolution in technical design, and a proactive, collaborative leadership style.

8. Frequently Asked Questions

Q: How much time should I spend preparing? A: We recommend dedicating at least 15–20 hours of focused study, specifically reviewing your past project architecture and practicing how to explain your design decisions.

Q: What is the most common reason candidates struggle? A: Candidates often focus too heavily on the "how" (the specific tool) and lose sight of the "why" (the business goal or the constraint). Ensure your answers always tie back to the project objectives.

Q: Is the culture collaborative or competitive? A: E.ON fosters a highly collaborative, team-oriented culture; we value individuals who share knowledge and elevate the performance of those around them.

Q: Will I be expected to write code? A: While this is an architecture role, you will be expected to demonstrate your ability to perform code-level performance tuning and troubleshooting as part of your design process.

9. Other General Tips

  • Use the STAR method: For behavioral questions, ensure your answers have a clear Situation, Task, Action, and Result.
  • Master the trade-offs: In system design, never provide a "perfect" solution without acknowledging the trade-offs regarding cost, latency, or complexity.
  • Know your resume: Be prepared to discuss any project on your CV in extreme detail, especially regarding the architectural challenges you faced.
