How to Apply for Junior Backend Developer

at Qwello

🏢 About Qwello

Qwello is at the forefront of Europe's electric vehicle revolution, designing user-focused EV chargers to accelerate the continent's transition to sustainable transportation. Working here means contributing to meaningful climate goals while being part of a remote-first, collaborative team that values innovation and impact.

About This Role

As a Junior Backend Developer, you'll design and implement backend services and serverless code in Python and Rust, directly shaping the architecture that powers Qwello's charging network. Your work will enable seamless integrations with partners and help scale the system to meet growing demand, making a tangible difference in the EV ecosystem.

💡 A Day in the Life

Your day might start with a stand-up meeting with your remote team, discussing progress on a new serverless endpoint for charging session data. You'll then dive into writing Python code for a partner integration, followed by a code review session where you provide feedback on a colleague's Rust module. In the afternoon, you might brainstorm architectural improvements for scaling the system, then wrap up by documenting your changes and updating the team on your progress.

🎯 Who Qwello Is Looking For

  • A developer with 2-3 years of professional experience, strong in Python, and eager to learn Rust (even if not yet proficient).
  • Someone who enjoys driving architectural improvements and can balance hands-on coding with strategic thinking about scalability.
  • A collaborative team player who actively participates in code reviews, planning sessions, and cross-team discussions.
  • A problem-solver who thrives in a remote environment, communicating clearly and taking ownership of their work.

📝 Tips for Applying to Qwello

1

Highlight any experience with serverless architectures (e.g., AWS Lambda, Azure Functions) and microservices, as Qwello specifically mentions serverless code.

2

Showcase your willingness to learn Rust by mentioning any personal projects, coursework, or contributions to open-source Rust repositories, even if small.

3

Emphasize your experience with EV-related or IoT systems if you have it—Qwello is in the EV charging space and values domain familiarity.

4

In your resume, use concrete metrics (e.g., 'Reduced API response time by 20%') to demonstrate impact in previous roles.

5

Tailor your cover letter to mention Qwello's mission of accelerating Europe's electric transition and how your skills align with that goal.

✉️ What to Emphasize in Your Cover Letter

["Your passion for sustainability and the EV industry, linking it to Qwello's mission.", "Specific examples of Python projects you've built or contributed to, especially those involving backend services.", "Your enthusiasm for learning Rust and any steps you've already taken (e.g., online courses, small projects).", 'Your experience with collaborative development (code reviews, pair programming) and remote work.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read about Qwello's product lineup and their user-centric design philosophy for EV chargers.
  • → Understand the European EV charging landscape and regulatory environment (e.g., EU's Alternative Fuels Infrastructure Directive).
  • → Look into Qwello's tech stack (if publicly available) or typical backend tools for EV charging networks (e.g., OCPP protocol).
  • → Check Qwello's blog or press releases for recent updates on partnerships or expansions.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Design a simple REST API for an EV charging station (e.g., start/stop charging, get status) and discuss trade-offs.
2 How would you approach migrating a monolithic backend to microservices?
3 Explain your experience with serverless computing and when you'd choose it over containers.
4 Describe a time you had to learn a new language or technology quickly for a project.
5 How would you ensure reliability and scalability in a system that handles real-time charging data?

⚠️ Common Mistakes to Avoid

  • Downplaying the importance of learning Rust—Qwello explicitly requires willingness, so show eagerness.
  • Submitting a generic application without mentioning EV or sustainability—Qwello's mission is core to their identity.
  • Neglecting to discuss remote work experience or self-discipline—since the role is remote, show you can work independently.
