Our partner is looking for a Senior Back-end Engineer - PHP, Node.js based in Germany. Join a fast-growing global engineering organization building technology that powers commerce at scale. As a Senior Back-end Engineer, you'll help design and deliver reliable, scalable systems that directly impact products and customers worldwide. You'll work within a product-focused engineering team where solving meaningful problems matters more than simply writing code. The role offers significant ownership, from technical design and implementation through prioritization, optimization, and continuous improvement. You'll collaborate closely with product managers and cross-functional stakeholders while contributing to a strong engineering culture. The environment encourages experimentation, knowledge sharing, pair programming, and practical use of AI-assisted development tools. Fully remote across EMEA, this is an opportunity to work with an ambitious international team while maintaining flexibility and autonomy. Accountabilities: * Design, develop, test, and deploy high-quality, scalable back-end software, while continuously improving existing code and architecture. * Contribute to the development of commerce solutions capable of supporting high-load and distributed environments. * Take ownership of technical initiatives from design through execution, ensuring projects are delivered against agreed priorities and business objectives. * Partner closely with product managers and stakeholders to translate business needs into effective technical solutions and challenge requirements when a different approach would create greater user or business value. * Apply sound architectural principles, including Domain-Driven Design (DDD), CQRS, and distributed systems patterns, to build maintainable and resilient services. * Participate actively in code reviews, refactoring, testing, debugging, and pair programming to maintain high engineering standards. * Identify and prioritize bugs, performance issues, and platform improvements, taking ownership of their resolution. * Monitor and optimize application performance, reliability, and overall system quality. * Contribute to a culture of continuous learning through technical knowledge-sharing sessions, mentoring, and best-practice discussions. * Use AI and LLM-based development tools thoughtfully to support architecture exploration, implementation, testing, debugging, documentation, and code quality. ## Related Videos - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [MySQL Protocol Features You Should Be Aware Of](https://www.wearedevelopers.com/videos/100267-mysql-protocol-features-you-should-be-aware-of) - [Local Candidates vs International Talent - Building the Very Best Dev Team](https://www.wearedevelopers.com/videos/1067-local-candidates-vs-international-talent-building-the-very-best-dev-team) - [Branch your database like your code: How schema changes and pull requests go hand in hand](https://www.wearedevelopers.com/videos/350-branch-your-database-like-your-code-how-schema-changes-and-pull-requests-go-hand-in-hand) - [Coding for Good: Achieving social change with an app](https://www.wearedevelopers.com/videos/1645-coding-for-good-achieving-social-change-with-an-app) ## Related Articles - [Backend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/196-backend-developer-salary-in-germany-2023) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Frontend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/195-frontend-developer-salary-in-germany-2023) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs)
