Company Description

At Enpal, we are pursuing the dream of building the largest renewable community in Europe. How do we make that happen? Enpal finally simplifies providing solar energy: We rent out solar systems, electricity storage, and wall boxes at an all-inclusive rate, supplemented by a favorable green electricity tariff; all intelligently connected to form an integrated overall solution. True to the motto "digital, decentralized, and 100% renewable", our heart beats both for the rapid development of a company and for combating the greatest challenge of our generation - climate change.

 

Job Description

  • Feature Ownership: Take full responsibility for the end-to-end development of new features, from frontend components to backend logic.
  • Frontend Development: Build responsive, high-performance user interfaces using React.js. You will implement complex state management and ensure seamless UI/UX.
  • Backend & Database: Architect and manage data models within Supabase (PostgreSQL). You will write Row Level Security (RLS) policies, manage Authentication flows, and leverage Supabase Edge Functions.
  • API Integration: Connect the frontend with various third-party APIs and internal services to ensure data consistency and real-time updates.
  • Performance Optimization: Profile and optimize frontend rendering and database queries to ensure a snappy user experience.
  • Code Quality: Participate in peer code reviews, write clean and maintainable TypeScript, and maintain technical documentation.
  • Venture Tech: Work directly with the Leadership and Tech Lead to iterate on the product architecture in an agile, sprint-based environment.

Qualifications

  • Education: You are pursuing a degree in Computer Science, Software Engineering, Informatic or a technical field.
  • Core Tech Stack: You have a strong command of React and JavaScript/Typescript (ES6+). 
  • Backend Knowledge: You understand Relational Databases (PostgreSQL). You know how to design schemas, handle joins, and understand the fundamentals of BaaS (Backend-as-a-Service) via Supabase or similar tools.
  • Technical Depth: You understand the "why" behind the code. Concepts like asynchronous programming, hooks, state lifting, and the request-response cycle.
  • Problem Solver: You have a "builder" mindset. You don't just follow instructions; you research solutions and implement the most efficient technical path.
  • Tools: Familiarity with Git/GitHub workflows is essential. Experience with Tailwind CSS, React Query, or Next.js is a plus.
  • Communication: You can articulate technical trade-offs and explain complex logic to both technical and non-technical team members.
  • Mentality: High standards for code quality and a proactive drive to squash bugs and optimize performance.
