• Participate in technical discussions, bringing ideas, asking questions, and helping your team move from concept to implementation.
• Support the delivery lifecycle, contributing to testing, debugging, and monitoring to ensure smooth releases.
• Learn from senior engineers, gaining experience in cloud infrastructure, system design, and performance considerations.
• Stay curious and experiment, exploring new tools and contributing to continuous improvement in engineering practices.

Requirements

• 2–4 years of professional experience as a backend or full-stack engineer, working with Node.js and TypeScript.
• Solid understanding of backend fundamentals, including asynchronous programming, API development, and data handling.
• Experience working with databases (PostgreSQL or similar).
• Working knowledge of unit testing and code quality practices.
• A collaborative mindset, curiosity, and willingness to ask questions and grow.
• Clear communication skills and a team-oriented attitude.
• Fluency in English, spoken and written.

Nice to Have

• Basic experience with AWS or other cloud environments.
• Exposure to event-driven systems or microservices.
• Some familiarity with frontend frameworks such as Svelte or React.
• Experience with CI/CD pipelines, Docker, or monitoring tools.

We Offer

• Grow quickly with support from experienced engineers who enjoy mentoring.
• Work in a product-focused environment where your contributions matter and reach users.
• Collaborate in a culture built on learning, ownership, and teamwork.
• Experience a flexible remote setup in Spain, with the option to join our Berlin office for collaboration.
• Opportunities to expand your responsibilities over time and influence how we build software.
