Vollständige Stellenbeschreibung

Zixio develops software for complex, business-critical processes in pharma, clinical trials, medicine and industry. Our systems are used in real operational environments where stability, security, traceability and maintainability matter.

We are a technology-driven team based in Berlin. We are looking for a Senior or strong Mid-Level Backend Engineer who solves problems independently, challenges technical decisions constructively and strengthens our engineering team.

What you will work on

You will mainly work on backend systems for complex B2B applications. Depending on the project, you will also be involved in architecture, data modelling, API design, deployments, testing, security topics and technical documentation.

Typical topics include:

backend development with PHP and relational databases
roles, permissions, workflows and business logic
API integrations and interfaces to external systems
architecture discussions with our CTO and project team
automated tests, debugging and quality assurance
deployment and operational topics
security aspects around data, authentication and interfaces
AI integrations, such as internal AI hubs or assistant systems

We care about speed, but not at the expense of structure, quality and maintainability.

What we are looking for

You are a good fit if you:

have several years of backend development experience, ideally with PHP and a common framework
work confidently with relational databases and APIs
understand design patterns, clean architecture and maintainable code
analyze problems systematically instead of only fixing symptoms
take web application security seriously
enjoy learning new technologies and technical concepts
like discussing technical decisions constructively
work independently, take ownership and collaborate well with a team

We are looking for someone who genuinely enjoys technology and wants to understand how systems can be improved.

Nice to have

Yii2, Laravel, Symfony or similar PHP frameworks
experience with complex B2B or long-running business applications
experience in regulated environments such as pharma, medicine, GxP, ISO or data protection
understanding of OWASP, logging, audit trails, roles and permission concepts
experience with automated testing, Docker, Linux, CI/CD or deployments
interest in AI integration, LLMs, RAG or automation
basic HTML, CSS and JavaScript skills

What we offer

a small, technically strong team with direct communication
hybrid work and flexible working hours
budget for training, conferences, certifications or coaching
room to shape technical topics and take responsibility
challenging projects instead of generic websites
work on systems that are actually used in production
close involvement in architecture and product decisions

Our engineering culture and stance on AI

We are building a solid, ambitious engineering team. We care deeply about technical quality: architecture, maintainability, security, testing, documentation and stable operation.

We also want our developers to keep growing. That means learning time, training budget, conferences, certifications and active support for technical development are part of how we work. We want people to stay close to new technologies and to have the space to become better engineers over time.

We have worked with AI technologies since 2017 and understand them beyond ready-to-use tools. We see AI as a way to empower engineers, not replace them. We follow current research, test new approaches critically and apply AI where it creates real value: internally in our own workflows and externally in customer systems. We are looking for someone who shares this mindset: curious about new technologies, but grounded enough to use them responsibly.
