When someone proposes a feature, you're already mapping failure modes * Comfortable with ownership: you ship it, you own it, you sleep soundly * Experience with Redis, Docker, Kubernetes, and GitLab CI/CD is a plus ## Description As our Backend Engineer, you'll build the engine behind our platform: designing features that hold up under enterprise traffic, optimizing the paths that can't afford to crack, and partnering closely with Frontend, Product, and Infrastructure to turn business needs into systems that simply work. Reliability doesn't just happen here, we design for it. You care about clean data, resilient systems, and performance that never cracks. Not because anyone will see your code, but because they'll feel it when it fails. At Dyflexis, that's not an option. * Design features that handle enterprise traffic across regions * Optimize critical paths for performance and reliability * Follow patterns for code quality, testing, and release readiness * Partner with DevOps on deployments and monitoring * Champion operational excellence in engineering decisions * Mentor engineers who are growing fast * Work in focused 6-week cycles, a deliberate post-scrum method built for builders ## Related Videos - [MySQL Protocol Features You Should Be Aware Of](https://www.wearedevelopers.com/videos/100267-mysql-protocol-features-you-should-be-aware-of) - [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) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [DevOps Maturity Check – a way to balance autonomy and alignment](https://www.wearedevelopers.com/videos/58-devops-maturity-check-a-way-to-balance-autonomy-and-alignment) - [Accelerating Authentication Architecture: Taking Passwordless to the Next Level](https://www.wearedevelopers.com/videos/733-accelerating-authentication-architecture-taking-passwordless-to-the-next-level) ## Related Articles - [The 7 Most Popular Backend Frameworks for Developers](https://www.wearedevelopers.com/magazine/403-the-7-most-popular-backend-frameworks-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [Mastering Remote Work: Tips for Developers](https://www.wearedevelopers.com/magazine/558-mastering-remote-work-tips-for-developers) - [Backend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/196-backend-developer-salary-in-germany-2023) - [20 Essential Tools For Backend Development](https://www.wearedevelopers.com/magazine/218-20-essential-tools-for-backend-development)
