How to apply for Senior Python Developer (w/m/d) - Remote

About node energy

node.energy builds software that optimizes energy systems for real estate to cut CO2 emissions and costs. Their SaaS product opti.node aggregates data for commercial operations of wind and solar plants and automates administrative and energy industry processes. Over 14,000 wind and PV plants, producing more than a third of German green electricity, rely on opti.node.

About the role

As a senior Python developer, you will be part of an in-house development team, independently implementing tickets and supporting team members with code structure and software architecture. You will help deliver robust features quickly that provide direct value to customers and users. Your work contributes to the success of opti.node and the energy transition.

A typical day

A typical day might involve reviewing tickets, writing and testing Python code for opti.node, and collaborating with team members on architecture decisions. You could also spend time supporting colleagues with code structure questions and ensuring features are delivered robustly. The exact routine is not specified, so ask about daily workflows during the interview.

Who node energy is looking for

• Several years of professional experience in Python development, ideally in a SaaS or energy-related environment.
• Strong skills in software architecture and code structure, able to guide other developers.
• Experience with the full software development lifecycle, from requirements analysis to implementation.
• Ability to work independently and take ownership of tickets in a remote setting.
• Interest in energy systems, renewable energy, or real estate optimization is a plus.

Tips for this application

• Highlight specific Python projects where you implemented features end-to-end, from requirements to deployment.
• Show experience with SaaS products or data-intensive applications, as opti.node handles large datasets from energy plants.
• Mention any background in energy, renewable energy, or real estate if you have it, to align with the company's domain.
• Demonstrate how you have supported other developers with code structure and architecture in previous roles.
• Since the role is remote in Germany, confirm your ability to work remotely and your familiarity with remote collaboration tools.

What to cover in your cover letter

['Your experience in Python development and software architecture, with concrete examples.', 'How you have contributed to robust feature delivery in a team setting.', 'Any exposure to energy systems, renewable energy, or real estate optimization.', 'Your motivation to work on software that supports the energy transition and reduces CO2 emissions.']

Research before applying

• Study the opti.node product and how it serves wind and solar plant operators.
• Learn about the German renewable energy market and the role of commercial operations for wind and PV plants.
• Research node.energy's clients and the scale of their operations (14,000+ plants, one third of German green electricity).
• Check the company's website and any public materials for their technology stack and development practices.

Likely interview topics

Based on the job description, expect questions about:

• Your approach to designing and implementing a new feature in a SaaS product like opti.node.
• How you handle code reviews and mentor junior developers on code structure.
• Experience with processing and aggregating large datasets, similar to energy plant data.
• Your understanding of the energy industry and renewable energy operations.
• How you prioritize tasks and work independently in a remote team.

Common mistakes to avoid

• Not demonstrating hands-on Python coding experience with specific examples.
• Ignoring the energy domain and failing to show any interest in renewable energy or real estate optimization.
• Applying without addressing the senior aspect, such as experience in architecture or mentoring.
