Web Engineer – Focus: React (m/f/d)

Your Responsibilities

As an experienced Web Engineer, you will play a key role in building and optimizing our web applications. Your main focus will be creating modern, high-performance user interfaces using React, ensuring smooth API integrations, and translating sophisticated design concepts into clean code.

• Core Development: You develop, maintain, and optimize our responsive web applications, ensuring high performance and a smooth user experience.

• Design Implementation: You have an eye for design and implement our designers' mockups precisely and with great attention to detail.

• API Integration: You seamlessly integrate various 3rd-party APIs and handle reliable data synchronization within our web ecosystem.

• AI-Assisted Tools: We welcome the use of AI-assisted development tools (Vibe Coding, Agentic Coding), but expect you to understand the potential risks and proactively manage code quality and technical debt.

• Quality Assurance: You safeguard the stability of your features through consistent test automation as a natural part of your workflow.

• Infrastructure Support: To ensure our applications run smoothly in production, you contribute to our modern cloud environment and support our deployment setups.

• Collaboration: You work closely with our product and design teams in an agile, iterative environment.

Your Competence

• Web Technologies: Solid experience with modern JavaScript frameworks, specifically React and Node.js. Knowledge of Ember.js is a plus.

• Testing: Strong routine in writing Unit and Integration tests using @testing-library/react and Vitest.

• Data Synchronization: Practical experience handling data layer mechanics via REST APIs, SSE (Server-Sent Events), and WebSockets.

• CI/CD Pipelines: Proven experience creating, maintaining, and supporting robust deployment pipelines.

• Containerization & Cloud: At least basic experience with Docker and the AWS stack, specifically utilizing AWS ECR, ECS, and related services to deploy and manage containerized applications.

• Design & UI: A strong sense of UI/UX mechanics and a passion for pixel-perfect implementations.

• Agile Working: Familiarity with agile methodologies (e.g., Scrum) and iterative development processes.

• Experience: Professional experience as a frontend or full-stack web developer.

• Languages: Fluent in English; German is a plus.

• Location: You are based in or willing to relocate to the Bremen area for regular hybrid collaboration at our headquarters.

Nice to Have (Fully Optional – An interest to learn these is enough!)

• Initial experience or touchpoints with the Web Audio API, Tone.js, or online DAWs.

• Basic knowledge of FFmpeg.

• Experience with End-to-End testing (e.g., Cypress).

• Basic familiarity with Terraform.

Your Personality

You identify with the following qualities:

Initiative

• You are eager to realize ideas.

• You push your ideas forward and inspire yourself and others to do so.

• You are resourceful, persistent and resilient in pursuing your goals.

• You are willing to take risks and take responsibility.

• You can make decisions in critical situations with confidence, value an autonomous way of working, and appreciate your responsibility for our product.

Organizational Talent

• You work in a structured way.

• You keep calm and maintain clarity—also in chaotic situations.

• You help your teammates to work in a well-organized way.

Communication Skills

• Working with people is easy for you.

• You are sensitive to international exchange and cultural differences.

• You make sure that your decisions and actions are aligned with your colleagues.

Joy of Conflict

• It is in your nature to question the status quo.

• You express your opinion and defend it in sparring.

• You know what “agree to disagree” means and can apply it.

Curiosity

• Ideally, you are also interested in music.

• You actively follow technical trends and new developments.

• You are interested in people and their personal development.

• You are interested in modern organization forms and prefer to work in a constantly changing and adapting system rather than in a fixed structure with clearly defined hierarchies.

We’d like you to participate!

Based on our product strategy, you should be able to set your own priorities in a flexible, informal working environment, with short paths and flat hierarchies. You help shape our path and provide new food for thought.

In return, you get the tools and equipment that work best for you (MacBook Pro, Windows laptop etc.) and, if desired, employment benefits to encourage capital formation (“Vermögenswirksame Leistungen”), a company bicycle or an investment in your health (EGYM).
