How to Apply for Fullstack Developer (US - ET)

at Chooose

🏢 About Chooose

Chooose is at the forefront of the lower carbon fuel value chain, building software that directly contributes to reducing carbon emissions. If you're passionate about using your technical skills to combat climate change and want to work on meaningful projects with real-world impact, this is the place.

About This Role

As a Fullstack Developer, you'll maintain and scale both front-end (React, TypeScript) and back-end (C#/.NET) systems, while also developing Python data pipelines and integrating AI/ML solutions. Your work will directly support commercial teams and customer-facing implementations, making you a key player in Chooose's mission.

💡 A Day in the Life

Start your day with a standup meeting (ET time) to align with the team. Spend the morning coding on a React component for a customer-facing dashboard, then shift to optimizing a Python data pipeline in the afternoon. End the day by reviewing a PR for a C#/.NET API and documenting your work for the commercial team.

🎯 Who Chooose Is Looking For

  • Experienced with React, TypeScript, C#/.NET, and Python, having built and scaled production systems in at least two of these.
  • Comfortable working autonomously in a remote US Eastern Time zone environment, with strong project management skills.
  • Excellent communicator who can translate technical details for commercial teams and customers.
  • Passionate about climate tech and eager to apply AI/ML to real-world problems in the carbon fuel industry.

📝 Tips for Applying to Chooose

1

Highlight any experience with carbon accounting, fuel value chains, or environmental tech in your resume and cover letter.

2

Showcase projects where you built end-to-end features across React frontend and C#/.NET backend, especially if they involved data pipelines.

3

Emphasize any AI/ML integration work you've done, even if it's small-scale, as Chooose specifically mentions this.

4

Tailor your application to demonstrate remote work success: mention time zone alignment (ET) and async communication tools you use.

5

Include links to your GitHub or portfolio with relevant code samples, particularly Python scripts or React components.

✉️ What to Emphasize in Your Cover Letter

["Your passion for climate tech and reducing carbon emissions – connect it to Chooose's mission.", 'Specific examples of scaling complex front-end and back-end architectures in previous roles.', "Your experience with Python data processing and AI/ML, even if it's side projects or coursework.", 'Your ability to work with commercial teams and customers, showing strong communication skills.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • Read Chooose's blog or case studies about their work in the lower carbon fuel value chain.
  • Understand the basics of carbon credits, offsets, and how software tracks fuel emissions.
  • Look into their tech stack: React, TypeScript, C#/.NET, Python – and any open-source contributions.
  • Check their LinkedIn or news for recent partnerships or projects to mention in your interview.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 How would you design a scalable data pipeline for processing carbon fuel data?
2 Describe a time you had to balance front-end performance with complex back-end logic.
3 What experience do you have with AI/ML integration in a production environment?
4 How do you prioritize tasks when working remotely across multiple time zones?
5 Explain a technical concept to a non-technical stakeholder (e.g., carbon credit calculation).

⚠️ Common Mistakes to Avoid

  • Don't submit a generic application – failing to mention climate tech or Chooose's mission shows lack of interest.
  • Avoid overemphasizing one part of the stack (e.g., only frontend) – they need fullstack versatility.
  • Don't ignore the AI/ML requirement – even if you're not an expert, show willingness to learn or past exposure.
