Frontend Engineer

Software Engineer (Junior-Mid)

We are looking for a Software Engineer (Junior-Mid) in Berlin (hybrid-mode) with a focus on frontend software development to join us remotely or in our office in Berlin. We are growing and need support in our team's mission to engage our users and make more people climate-active!

As an engineer at Ecosia, you will work with a cross-functional team to contribute to the acquisition and retention of users by delivering new product features for our web application and/or browser extensions. Day-to-day, you will dive deep into our frontend tech stack, solving problems from the user interface to the server side of our applications.

Do you want to become part of a fun team, shape a product used by millions of users daily, and help regenerate our ecosystem? Join us!

What You'll Do

1. Build, test, and deploy the frontend user experience of Ecosia (client and server-side).
2. Contribute to the development of new features in our cross-functional product team.
3. Support your team members in backend-focused work-streams, if you are interested.
4. Advance our engineering practices for the frontend within your areas of interest.
5. Share what you know and empower your peers to gain deeper technical knowledge.
6. Strengthen our collaborative and inclusive culture, in alignment with our core values and ways of working.

What You Bring

1. Experience building and deploying production code in JavaScript / TypeScript, ideally (but not required) in Vue.js, NuxtJS, Vite, or equivalent (e.g. React).
2. Motivation to dive deep technically, learn and apply best practices, and grow professionally.
3. Ability to work collaboratively with Product and other engineers.
4. Good communication skills in written and verbal English.

And maybe:

• Experience building browser extensions.
• Basic backend knowledge or even experience with serverless platforms like CloudFlare workers.
• Experience (or interest) in mobile App development (iOS / Android).

The Hiring Process

Our hiring process consists of 3 steps:

1. Quick first call with our recruiter.
2. A mix of tech and cultural conversation with an EM/PM and one of your potential future colleagues.
3. Pair programming session with some hands-on coding.

By default, all steps are done remotely.

About Our Technology Stack

1. Backend: Node.js, Go-lang or Python services using REST and gRPC.
2. Frontend: Vue.js/NuxtJS, JavaScript (Typescript), Astro.
3. Infrastructure: Cloudflare, AWS, Kubernetes (EKS), and Terraform.
4. Tooling: Prometheus and Grafana for monitoring, GitHub and CircleCI for our CI/CD.

We don't expect you to have experience with all of the above, but if you're curious to learn and pair across these technologies, this could be a good match!
