full-stack developer for digital marketing in Berlin

Описание:

At PSI Software SE, we are shaping the future of industrial software infrastructure—with solutions in the areas of Grid & Energy, Manufacturing, and Logistics. As a Senior Full-Stack Developer on the global Digital Marketing team, you’ll bridge the gap between our technological excellence and our global brand presence.

Задачи:

You’ll develop and optimize our custom TYPO3 extension to ensure seamless, high-performance, and secure real-time data transfer to our CRM. Working together with the interdisciplinary web team (comprising design, content, and marketing), you’ll design and implement new, interactive features for our corporate website that reflect PSI’s high technological standards. You’ll identify bottlenecks in lead and data flows and set up automated workflows between the CMS and CRM wherever they reduce manual work and improve data quality. You’ll analyze technical performance metrics and analytics data, derive concrete optimizations for load times, SEO, and the user journey, and implement these directly in the code. You’ll ensure a clean, maintainable backend and a modern, accessible frontend to guarantee a contemporary, future‑proof web presence for a leading B2B software company.

Требования:

• Proven experience in PHP-based backend development and writing custom, maintainable, and secure TYPO3 extensions (ideally using Extbase and Fluid while adhering to current security standards).
• Proficiency in HTML5, CSS/SASS, and JavaScript to implement responsive and accessible user interfaces.
• Hands‑on experience integrating third‑party systems via REST or SOAP APIs, as well as secure handling of data streams.
• In‑depth knowledge of the technical implementation and configuration of Google Analytics 4 (GA4) and Google Tag Manager (GTM).
• Since you’ll be working in an international environment and collaborating closely with global stakeholders, business‑level English (spoken and written) is a mandatory requirement.
• You bring a strongly solution‑oriented mindset to the table.
• When the marketing team has an idea, you take on the challenge, translate it into technical possibilities, and say, “I’ll find a way to make this happen.”
• We value and encourage an active, self‑organized approach to work.
• You don’t wait for detailed task assignments; instead, you proactively drive your projects forward and structure them independently.
• You enjoy explaining complex technical concepts in a way that’s easy for your colleagues in marketing to understand, and you work together as equals to refine the best user experience.
• Будет плюсом: Some prior experience with CRM’s APIs
• Experience with no‑code/low‑code interface tools for rapid workflow automation
• A strong understanding of technical SEO factors (e.g., Core Web Vitals) and user‑centered UX design
• Good German language skills are a plus, but not a requirement

We believe in the power of face‑to‑face interaction, but also in flexibility. You’ll work with us at least two days a week in our modern office in the heart of Berlin (near Alexanderplatz); the rest of the week, you can work flexibly from home—whichever suits you best. You’ll be part of our agile, six‑person web and digital marketing team. We work in an interdisciplinary, flat‑structured environment with short decision‑making paths. We’re in a phase of change. For you, this means: Some processes are already established and running smoothly, while others still have plenty of room for improvement. If you’re looking for rigid, perfectly predefined structures, you may have to adjust to our way of doing things. However, if you love actively shaping processes, setting your own standards, and leaving things better than you found them, you’ve come to the right place. A key role with direct influence on the technological advancement of our global digital presence.

• Flexible work hours
• the option to work partially from home
• a flexible, trust‑based vacation policy to ensure your optimal work‑life balance
• free drinks and a basket of fresh fruit in the office
