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 the data model to the user interface, enjoy conceptualizing technical solutions, and take responsibility for ensuring they are implemented as planned? Then, as a Senior Fullstack Developer (m/f/d) / Senior Web Developer PHP/Laravel (m/f/d) at Händlerbund, you're exactly in the right place!

With us, you'll develop a platform that digitally maps and automates legal processes. From creating legal content to contract and review processes, as well as data protection and security issues. This includes interfaces and plugins through which our content reaches the shops of our members, 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 their implementation, guide other developers in the project, and keep all stakeholders informed about the progress. You will complete smaller projects independently from start to finish, and for larger ones, you will work in a team with Laravel and Livewire in the stack.

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

• Ownership for Implementation: Responsibility for ensuring a project goes from conception to go-live. Assigning and prioritizing tasks, keeping track of progress, making technical decisions, and removing 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 should be shared within the team and in documentation, not just kept by 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. Smaller projects independently from start to finish, larger ones within the 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 possibilities concerning 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 with Livewire, Alpine.js, Flux UI, and Tailwind CSS in the frontend.

• 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 fosters growth in others.

• 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 an afterthought.

• 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 Essential

• 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.

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

• Structured Communication: You clearly communicate the project status to technical and non-technical stakeholders, even when things don't go as planned.

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

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

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

Code. Chill. Repeat.

• 4 Days of Code – 3 Days for Yourself: The 4-day week is standard here. Not a gimmick, but reality. You work remotely or from our Leipzig office – whichever way you perform best. Flexible hours, no micromanagement, full responsibility. And yes: permanent contract from the start.

• Your Stack, Your Style: We value smart solutions, clean code, and people who think along. Do you want to have a say, experiment, and not just work through tickets? Here you go. Plus: mentoring, further training as needed, and room for real development.

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

• Professionalism: Real quality, not show-off. We live 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 Make a Difference: Childcare subsidy, support with retirement planning, Leipzig public transport ticket, or sports offers for your balance – from a home gym to a fitness studio for mind and body.

Don't feel like writing long cover letters? No problem! Just briefly tell us why you want to be part of Händlerbund and why we would be a good fit for you. Use the option to apply online via our application form.

We look forward to receiving your application, including your salary expectations and earliest possible start date.
