Senior Fullstack Developer PHP/Laravel (m/f/d) - Remote, 4-Day Week

Do you want to work on a Legal Tech application that functions as a digital legal department for e-commerce companies? Do you think in systems from data model to user interface, enjoy conceptualizing technical solutions, and take responsibility for ensuring they are implemented correctly in the end? Then, as a Senior Fullstack Developer (m/f/d) / Senior Web Developer PHP/Laravel (m/f/d) at Händlerbund, you are exactly in the right place!

With us, you will develop a platform that digitally maps and automates legal processes. From the creation of legal content, through contract and auditing processes, to data protection and security issues. This includes interfaces and plugins through which our content reaches our members' shop systems, as well as integrations with partner systems. The goal is to translate complex legal requirements into reliable, understandable, and efficient digital workflows.

In this role, you will take on the technical leadership of projects that we implement in small project teams: You will conceptualize solutions, be responsible for implementation, guide other developers in the project, and keep all stakeholders informed of the progress. You will independently implement smaller projects completely, and for larger ones, you will work in a team with Laravel and Livewire in the stack.

• Technical Conception: Analysis of requirements, design of solution architecture, definition of data models and interfaces, as well as estimation of effort for features and projects.

• Ownership for Implementation: Responsibility for a project to go from conception to go-live. Assign and prioritize tasks, keep track of progress, make technical decisions, and remove blockers.

• Guidance & Knowledge Transfer: Technical leadership of other developers in the project through clear technical specifications, pairing, and code reviews in both backend and frontend. Knowledge about architecture and decisions lands in the team and in documentation, not just with you.

• Reporting: Regular, understandable reports on status, risks, and next steps to the Team Lead, Product Owner, and stakeholders.

• Fullstack Development: Implementation with Laravel, Livewire, Alpine.js, Flux UI, and Tailwind CSS. Independently implement smaller projects from start to finish, larger ones in a project team.

• Partner Connections & Integrations: Solution evaluation, implementation, and documentation of interfaces to partner and third-party systems.

• Architecture & Technology Evaluation: Contribution to architecture, development standards, and tooling; evaluation of new technologies, frameworks, and AI use cases in terms of their concrete benefit for the product and team.

Technical

• Several Years of Experience with PHP & Laravel: Development of web applications across the entire stack, ideally in the frontend with Livewire, Alpine.js, Flux UI, and Tailwind CSS.

• Conception & Technical Leadership: Experience in developing technical concepts and taking responsibility for their implementation, either alone or as technical lead of a project team.

• Code Reviews Across the Entire Stack: Practical experience in reviewing backend and frontend code and the ability to provide feedback in a way that helps others grow.

• Testing Experience: Proficient use of PHPUnit or Pest and experience with test strategies in larger codebases. For you, tests are part of the implementation, not rework.

• Databases & APIs: Proficient use of relational databases, data modeling, and API design.

• Agile Teamwork: Experience in agile teams, ideally with Scrum, including close collaboration and continuous exchange.

Nice to Have, but Not a Must

• DevOps Experience: Cloud systems, PaaS platforms, containers, CI/CD, or Linux server administration (e.g., DigitalOcean and Laravel Cloud)

• Experience with shop systems and developing plugins or apps for them (e.g., Shopify or JTL)

• A feel for UX and experience in designing user-friendly interfaces

• Experience with event-driven architectures, queues, or asynchronous processing

• Experience with integrating LLM APIs into product features (prompting, evaluation, guardrails)

Personal

• Ownership: You feel responsible for the outcome of a project. From the initial sketch to go-live and beyond, not just for your own tickets.

• Systemic Thinking: You see the impact of changes across component and team boundaries.

• Structured Communication: You prepare the status of a project in an understandable way for technical and non-technical stakeholders, even when things don't go according to plan.

• Pragmatism: You find the balance between a clean solution and pragmatic progress.

• Knowledge Transfer: You enjoy sharing knowledge and making others in the team better, e.g., through reviews, pairings, and documentation.

• AI as a Tool: You naturally use AI tools in your daily development work and soberly assess where they provide real value in the product and where they don't.

Code. Chill. Repeat.

• 4 Days of Code – 3 Days for You: The 4-day week is standard with us. Not a gimmick, but reality. You work remotely or in the Leipzig office – however you perform best. Flexible hours, no micromanagement, full personal responsibility. And yes: unlimited contract from the start.

• Your Stack, Your Style: We love smart solutions, clean code, and people who think along. Do you want to have a say, experiment, and not just tick off tickets? Here you go. Plus: Mentoring, training as needed, and space for real professional development.

• Remote First, Team Always: Despite remote work, team spirit remains. We celebrate releases, grill in the summer, and toast to great ideas. Your office dog is just as welcome with us as your favorite editor.

• Professionalism: Real quality over show-off. We practice agile development with clear iterations and direct feedback. You work with modern, professional tools, with clear roles and responsibilities – you know exactly what your job is and have the freedom to do it the right way. Clean code, smart decisions, and a team that works together. Professionalism here means: You can concentrate on what you do best – developing.

• Snacks, Swag & Soft Drinks: Fruit, muesli, coffee, water – all for free. No dress code. Come as you are. The main thing is that you feel comfortable.

• Perks That Matter: Childcare subsidy, support for retirement provision, Leipzig public transport ticket, or sports activities for your balance – from a home gym to a gym for mind and body.
