Liquid Barcodes is a SaaS platform helping convenience and foodservice retailers build branded apps, loyalty programs, and subscription programs that drive customer engagement.
We are looking for a strong backend developer with around 5+ years of experience who wants more ownership, more technical influence, and room to grow within a fast-scaling SaaS company.

This is a backend role with real impact. You will help design, build, and improve product features used by leading retail brands, working closely with Product, Engineering, Customer Success, and Support.
Building and owning backend features for retail customers
Contributing to architecture, technical standards, and long-term platform quality
5+ years of software development experience
~ Strong backend experience with .NET and C#
~ Experience with REST APIs, microservices, MySQL or DocumentDB
~ Familiarity with RabbitMQ, GitHub, CI/CD, and modern DevOps practices
~ AWS experience is a plus
~ Strong English skills, both written and spoken





We are actively adopting AI-assisted development across the software development lifecycle.
This could include using AI to explore existing code, speed up implementation, generate and improve tests, support debugging, improve documentation, review approaches, or increase overall code quality.
We care less about hype and more about practical usage: knowing when AI can help, when human judgment matters most, and how to use these tools responsibly and reasonably to build better software.

We have an office in Málaga city centre, but daily office attendance is not required.
We meet in person for trainings, team sessions, and important alignment moments, usually around two times per month on average. You will join a product-led SaaS company with real customers, real scale, and ambitious growth.
This is a great opportunity for someone technically strong who wants to grow into a bigger role, work in a modern AI-enabled software development environment, and have direct impact on both
