Role overview

A small cross-functional product team building a B2B marketplace and data platform for the battery lifecycle is hiring a fullstack engineer whose primary strength lies in backend engineering. The role spans architecture, APIs, infrastructure, and production-ready frontend work inside a containerized microservices environment on AWS. It suits someone who wants true end-to-end ownership of features rather than staying inside a backend or frontend silo.

Responsibilities

• Design, build, and operate container-based backend services, APIs, and AWS infrastructure
• Shape solutions for distributed, message-driven, service-oriented systems
• Implement the frontend portion of features in Angular based on product requirements and designs
• Translate business requirements into pragmatic technical solutions while continuously improving performance, reliability, and maintainability
• Write clean, testable code, run thorough code reviews, contribute to engineering standards, and debug issues across the full stack
• Collaborate closely with product, design, and other engineers in an agile setup, including use of AI coding assistants as a regular part of the workflow with critical review of generated code

Requirements

• 5+ years of professional software development experience, the majority focused on backend engineering
• Strong professional experience with PHP and Symfony, or solid experience in Java, Python, or Node.js plus readiness to work in PHP and Symfony from day one
• Deep understanding of REST APIs, message-based systems, microservice architectures, and distributed systems
• Strong experience with relational databases, data modeling, and schema design
• Hands-on professional experience with AWS, containerization, and infrastructure-as-code tooling
• Comfort implementing production-ready Angular features and working across backend, frontend, and infrastructure

Nice to have

• Prior experience leading or mentoring engineers
• Familiarity with AI or LLM tooling, MCP servers, or agent orchestration
• Component libraries, design systems, and frontend performance optimization work
• AWS certifications

Benefits and work setup

• Remote-first within Germany, with a hybrid-friendly modern office offering open spaces, meeting pods, and a coffee bar
• Flexible working hours rooted in a low-hierarchy, open-feedback, results-oriented culture
• Multinational team of 18+ nationalities with English as the working language
• AI coding tools treated as a standard part of the engineering workflow
• Fully paid annual company workation
• Learning and development budget covering conferences, certifications, and language courses
• Monthly lifestyle voucher for sports, takeout, or shopping
