How to Apply for Software Engineer

at Furbnow

🏢 About Furbnow

Furbnow is a mission-driven company focused on making homes more energy-efficient through retrofit services, directly tackling climate change while helping homeowners save money. Unlike generic tech companies, they work at the intersection of environmental impact, complex energy data, and practical home improvements, offering engineers a chance to build software with tangible real-world benefits. Their focus on cutting carbon emissions and energy bills creates a purpose-driven work environment where technology directly contributes to sustainability goals.

About This Role

This Software Engineer role involves full-stack development with Django to automate admin tasks and improve existing systems, specifically dealing with messy real-world data like energy calculations, supplier pricing, and grant eligibility rules. You'll collaborate closely with non-technical teams like project coordinators and surveyors to understand and solve practical problems in the home retrofit process. The impact comes from building tools that streamline operations, reduce manual work, and ultimately help more homeowners access energy-efficient solutions.

💡 A Day in the Life

A typical day might involve collaborating with project coordinators to understand pain points in their workflow, then designing and implementing Django features to automate those processes. You could be working with energy calculation data to improve accuracy, refactoring existing code for better performance, or building internal tools that help surveyors and coordinators work more efficiently with customer data and retrofit plans.

🎯 Who Furbnow Is Looking For

  • Has hands-on Django platform development experience with proven ability to build features end-to-end from database schema to UI
  • Possesses specific experience with energy calculations and heat loss modeling, particularly familiarity with Home Digital Twin models used in retrofit assessments
  • Demonstrates experience building internal tooling to improve team effectiveness, with examples of automating processes or creating efficiency tools
  • Has worked across customer journeys, project tracking systems, and system integrations, showing ability to connect different parts of a business workflow

📝 Tips for Applying to Furbnow

1

Highlight specific Django projects where you've built features end-to-end, particularly those involving database design and UI implementation

2

3

Showcase examples of internal tooling you've built to improve team efficiency, especially tools that automated manual processes

4

Demonstrate understanding of Furbnow's mission by connecting your experience to how it could help streamline retrofit services

5

Include examples of collaborating with non-technical stakeholders to understand requirements and build solutions

✉️ What to Emphasize in Your Cover Letter
