• Contribution to platform evolution through active involvement in new project definitions, architectural discussions, and long-term technical decisions shaping future services

• Ongoing support for product teams through hands-on contributions across codebases, code reviews, and design discussions to ensure quality, consistency, and shared ownership

• Operational responsibility for production stability including monitoring, incident response, and incremental improvements within a partially migrated legacy-to-modern system landscape

Tech-Stack

• Frontend & Interaction: React, TypeScript, HTML, CSS for feature-rich and interactive customer-facing applications

• Backend & APIs: Node.js services and clean, maintainable server-side logic supporting the event and configurator ecosystem

• Testing & QA: unit tests and end-to-end tests for robust test coverage across frontend features and critical user flows

• Infrastructure & Monitoring: AWS for scalable hosting, Grafana with OTel standards for observability across services and application behaviour

Your benefits 

• We value flexibility: Flexible remote work, part-time options, modern hardware (Macbooks), collaborative office spaces (flex desks)

• We embrace new work: Agile working, fair pay, competency- and leadership models

• We care for your well-being: Nilo.health, Corporate Benefits, JobRad, workations, sabbaticals, 30 days paid vacation, and your personal benefit of choice: Wellpass, Hansefit or DB Jobticket

• We want to grow with you: Internal development, coaching, regular feedback- and growth processes, flexible external learning

• We are one team: Office meals, (voluntary) events, remote team building, furry office friends and exclusive family & friends discounts

Your profile

• +4 years of experience as a fullstack engineer working across frontend and backend in complex, product-driven environments

• Strong expertise in TypeScript, React, and Node.js with solid API design experience and familiarity with modern cloud, CI/CD, and testing practices

• Fluency in English (written and spoken) required for daily operations and team collaboration

Your mindset

• Pragmatic – You focus on practical, reliable solutions, balancing code quality, performance, cost, and complexity when making day-to-day technical decisions.

• Collaborative – You work openly with product, data, and DevOps partners, offering support and feedback while keeping shared goals and priorities in view.
