Job description

WHAT WE ROCK AT!
As consultants and creators, we act at eye level with our clients - and with each other, too: With us, you will find short decision-making processes, flexible room for manoeuvre and plenty of space for your ideas and further development. Whether apprentice or management, your colleagues are real personalities who all learn something new every day through an open exchange on challenging topics and grow beyond themselves together: they are mums and dads, travel enthusiasts, musicians, headbangers, nerds...

What unites us? We are people with team spirit, high self-motivation and enthusiasm for digital topics.

Curious? Then take a look and get to know the team.
WHAT WE OFFER...
  • Advance Your Technical Leadership Develop your solution architecture skills through nexum Academy, technical leadership workshops, industry conferences, and advanced certifications in modern development frameworks.
  • Strategic Impact Lead complex client engagements, shape technical strategies, and drive architectural decisions that directly influence project success and client satisfaction.
  • Work Your Way Flexible hours and remote options that support your analytical thinking process. Choose your preferred setup—Mac or Windows—configured for maximum productivity.
  • Beyond the Code Connect with fellow solution architects and tech enthusiasts through team activities, tech meetups, and our annual nexum summer party.
WHAT YOU WILL DO WITH US
  • Lead Technical Solution Design Transform complex business requirements into scalable technical architectures, owning the complete solution lifecycle from initial analysis to successful deployment.
  • Act as Primary Problem Solver Identify root causes behind technical challenges, team dynamics issues, and project roadblocks - then design practical solutions that address the real problems, not just symptoms.
  • Navigate Complex System Landscapes Evaluate and integrate diverse technologies including headless CMS platforms (Drupal, Storyblok, Magnolia), eCommerce solutions (Shopify, commercetools, Shopware, SAP Hybris), ERP systems, CRM platforms, payment gateways, and various APIs to create cohesive, functional ecosystems.
  • Lead Solution Architecture Design comprehensive technical solutions from initial concept through implementation, creating detailed architectural documentation and managing complex system integrations across multiple platforms.
  • Scale Across Project Sizes Lead both focused website projects and complex multi-system enterprise initiatives, adapting your approach and technical solutions to match project scope, timeline constraints, and business requirements.
  • Champion Requirements Engineering Excel at stakeholder communication, requirement gathering, and translating business needs into clear technical specifications and implementation roadmaps.
  • Architect Full-Stack Solutions Design end-to-end solutions spanning frontend interfaces, backend services, databases, and integrations while ensuring scalability and maintainability.
  • Provide Technical Mentorship Guide development teams through complex technical challenges, share architectural knowledge, and elevate overall team capabilities.
  • Bridge Business & Technology Serve as the key technical advisor for client relationships, providing accurate effort estimations and communicating technical concepts to non-technical stakeholders.
YOU ARE...
  • Solution-Oriented Thinker You excel at breaking down complex problems into manageable components and designing elegant solutions that balance technical excellence with business pragmatism.
  • Technology-Agnostic Problem Solver You understand that technology platforms are tools to solve business problems. While you have experience with various systems, you excel at quickly understanding new platforms and adapting your approach to whatever technology stack the client needs.
  • Transformational Solution Designer You excel at envisioning and architecting complete technical transformations, from analyzing current state challenges to designing future-state solutions that enable business objectives.
  • Strategic Documentation Creator You understand how to create comprehensive technical documentation that serves multiple audiences - from detailed architectural specifications to executive-level transformation proposals.
  • Process and System Integration Expert You see beyond individual technologies to understand how entire business processes can be digitized, optimized, and integrated across multiple systems and stakeholders.
  • Adaptable Project Leader You're equally comfortable leading a small, focused team on a quick integration project as you are coordinating multiple teams on a complex multi-platform solution.
YOU HAVE...
  • Communication Excellence Advanced English proficiency for international collaboration. German knowledge is a plus but not required.
  • Technical Leadership Experience 7+ years of progressive development experience with proven project leadership and solution architecture delivery.
  • Full-Stack Expertise Comprehensive experience across frontend (React, Vue, Angular) and backend technologies (Node.js, PHP, Python), with deep understanding of both domains.
  • Architecture & Patterns Knowledge Strong foundation in software architecture patterns, design patterns, and systems integration with experience in scalable solution design.
  • Systems Integration & Platform Knowledge Broad experience with modern CMS platforms (Drupal, Storyblok, Magnolia, Craft), eCommerce systems (Shopify, commercetools, Shopware, SAP Hybris), ERP platforms, CRM systems, and understanding how different enterprise systems integrate and scale.
Note: The technologies listed represent common platforms in our client projects. We value your ability to quickly master new systems and integrate unfamiliar platforms over deep expertise in any specific tool.

  • Problem Diagnosis & Resolution Proven ability to identify root causes of technical, team, or process issues and implement effective solutions that address underlying problems.
  • Solution Architecture & Documentation Proven ability to design comprehensive technical solutions and create detailed architectural documentation that serves both technical teams and business stakeholders.
  • Cross-Platform Architecture Experience designing solutions that span multiple systems and technologies, with understanding of API ecosystems, data flows, system interdependencies, and business process digitization.
YOU ARE WELL VERSED...
  • Development Technologies Modern frameworks and languages (JavaScript/TypeScript, Node.js, PHP, React, Vue), version control (Git), and CI/CD pipelines.
  • Architecture & Infrastructure Cloud platforms (AWS, Azure, GCP), containerization (Docker), microservices architecture, and scalable system design principles.
  • Project Management & Methodology Agile/Scrum practices, requirement documentation, effort estimation techniques, and cross-functional team coordination.
  • Platform & Integration Expertise Modern CMS platforms (Drupal, Storyblok, Magnolia), headless commerce solutions (Shopify, commercetools, Shopware, SAP Hybris), ERP/CRM system integration, API ecosystems (REST/GraphQL), and enterprise system integration patterns.
  • Problem-Solving Methodologies Root cause analysis, team dynamics assessment, process optimization, and systematic troubleshooting across technical and organizational challenges.
  • Multi-Scale Project Experience Comfortable working on everything from focused website builds and rapid integrations to large-scale, multi-platform enterprise solutions with multiple stakeholder groups and complex system landscapes.
