How to apply for Full Stack Developer (60-100%)

About Hyphen Global AG

Hyphen Global AG is a climate-tech company focused on precision emissions verification through real-time atmospheric greenhouse gas monitoring, combining hardware, data science, and software to hold polluters accountable. Working there means your code directly supports environmental impact, not just business metrics, in a mission-driven Zurich-based team. The 60–100% flexibility and remote-friendly setup suit engineers who want meaningful work with autonomy.

About the role

As a Full Stack Developer at Hyphen Global, you'll build the web interfaces and data visualizations that turn raw atmospheric measurements into actionable emissions insights, while also developing pipelines that ingest and process data from sensors and external sources. You'll collaborate with backend engineers on APIs and work across the full software lifecycle, from design to deployment. This role is impactful because your frontend and data work directly enable verifiable climate accountability.

A typical day

You might start by reviewing sensor data ingestion logs and fixing a pipeline issue, then spend the afternoon building a new React component to visualize emissions trends for a client dashboard. Later, you'd sync with backend engineers on API changes and deploy an update to Google Cloud, all while managing your own schedule in a flexible, remote-friendly setup.

Who Hyphen Global AG is looking for

• Strong full-stack engineer with production experience in JavaScript/TypeScript, Python, and SQL, comfortable moving between frontend and data pipeline work.
• Hands-on with React and Next.js, and able to design intuitive data visualizations for complex scientific or environmental data.
• Familiar with cloud infrastructure, ideally Google Cloud (or AWS/Azure), and capable of deploying and maintaining services in a remote setting.
• Self-directed and proactive, able to take initiative, communicate clearly in a distributed team, and translate cross-functional requirements into shipped features.

Tips for this application

• Highlight any project where you visualized scientific, environmental, or sensor data—Hyphen's core product is emissions monitoring, so data-viz relevance matters more than generic dashboard work.
• Show concrete experience with Python data pipelines (ingestion, processing, integration) alongside your frontend stack, since the role explicitly splits time between React/Next.js and backend data work.
• Mention Google Cloud specifically if you have it; if not, explain your AWS/Azure experience and willingness to ramp up on GCP, as they prefer GCP but accept other clouds.
• Demonstrate remote-work self-direction in your application—give an example of a project you drove independently without close supervision.
• Tailor your CV/portfolio to emphasize full software lifecycle involvement (design, implementation, testing, deployment), not just feature coding.

What to cover in your cover letter

["Your motivation to apply your full-stack skills to climate and emissions verification, connecting your work to Hyphen's mission of real-time greenhouse gas monitoring.", 'A specific example of building data visualizations or frontend interfaces that made complex data understandable to non-technical users.', 'Your experience developing data pipelines in Python and integrating data from multiple sources, ideally with cloud deployment experience.', 'Your ability to work proactively and independently in a remote or flexible setup, with a concrete example of taking initiative.']

Research before applying

• Understand Hyphen Global's technology and mission: how they use real-time atmospheric monitoring to verify emissions, and who their customers or partners are.
• Look into the science and challenges of greenhouse gas monitoring and emissions verification, so you can speak credibly about the data you'd be working with.
• Research their tech stack signals—check their website, LinkedIn, or job posts for mentions of React, Next.js, Python, and Google Cloud to align your examples.
• Explore the Zurich/Swiss climate-tech and startup ecosystem to understand the context, funding landscape, and potential competitors or collaborators.

Likely interview topics

Based on the job description, expect questions about:

• How you would design a frontend data visualization to display real-time atmospheric greenhouse gas measurements in a clear, trustworthy way.
• Your approach to building a data pipeline that ingests, processes, and integrates data from heterogeneous sources (e.g., sensors, APIs, databases).
• A deep-dive into your React/Next.js experience, including state management, performance, and API consumption.
• How you collaborate with backend teams to design and consume API endpoints, and how you handle cross-functional requirements.
• Your familiarity with Google Cloud (or AWS/Azure) and how you'd deploy and monitor a full-stack application in a remote team.

Common mistakes to avoid

• Submitting a generic full-stack application without referencing emissions, climate data, or Hyphen's specific mission—this role requires mission alignment.
• Overemphasizing only frontend or only backend experience; the role is explicitly full-stack with data pipeline work, so show both sides.
• Ignoring the remote/independent work requirement—if you only describe team-based, closely supervised work, you may seem unsuited to their proactive remote culture.
