1. We are hiring: Front End Developer


    Are you stuck in a boring job? Are you yearning for a chance to spread your wings? Good news: the wait is over!

    Do you want to create elegant and useful interfaces for world-leading brands and cutting-edge web applications such as and Do you feel comfortable carrying an idea from first draft to finished product while working with a closely-knit team of experts? Do you love to turn complex interaction models into beautiful and readable code? Do you want to create products that enable people to be successful doing what they love?

    Still nodding? Then you should apply, provided you can bring along the following:

    • 5+ years of experience in front-end development
    • Fluency in JavaScript, HTML, CSS (SASS), and jQuery
    • Working knowledge of Backbone.js, Bootstrap, and CoffeeScript
    • A sound understanding of Rails
    • Familiarity with GitHub and Heroku
    • EU citizenship or a work permit for Austria

    Whom you’ll work with

    Left to right: Thomas, Nadja, Dave, Christina, Tom, William — and the Riesenrad.

    Thomas is our product guy. He leads all things UI and UX and sets the direction of the ship, with plenty of output from his trusted team of innovators. He also happens to be the founder and CEO of Wollzelle.

    Nadja keeps the wheels turning: whether she’s compiling research, performing miracles in Photoshop or torturing our beta products at the testing stations, her results will surprise you!

    Dave is our resident genius for all things IT. His heart is about as big as his brain, and they have both earned him a central place on the team. He specialises in un-sticking whatever locks up as we develop new products.

    Christina keeps the pace and manages our clients. As COO, she’s in charge of design and project management, personally leads our key accounts, and makes sure we stay on message at all times. She knows the Gucci brand inside-and-out, to the point we sometimes feel she has psychic powers.

    Tom is the back-end magician in charge of continuous integration. He holds all the keys to the engine room and keeps everything on board running smoothly, whatever the weather.

    William performs front-end magic. His are the shoes you are poised to fill, but fret not: he’ll show you the ropes, and, of course, the whole team will rally round to ease your foray into the job!


    We are…

    • Centrally located in Vienna, a world capital with amazing history and a bright future.
    • Passionate about nurturing a diverse team in a forward-looking environment.
    • Flexible with holidays and downtime, provided the work gets done.
    • Committed to offering great health benefits to everybody (Mens sana and all that.)
    • Open to supporting your relocation efforts, provided you are set up to work in the EU.
    • Excited about technology — which is why you’ll be provided with the very best at all times.
    • Generous with our salaries and appreciative of your talents. The salary for this position starts at 35K€ gross per annum. The actual salary will depend on your qualifications.

  2. Infographic on the new EU VAT rules


    New VAT regulations came into effect on 1 January 2015. If you sell digital goods or services (Saas) within the European Union, it is essential that you review your invoices for compliance. As so often, the rules are confusing, and failure to conform could have dire consequences.

    There is so much contradictory information out there, especially for intra-European relationships, that I decided to put together a little flowchart, to facilitate our invoicing. Our friends saw it, liked it, and asked for it, so there it is, for your personal enjoyment. We hope it helps you get back to actual productive work as soon as possible!

    These new VAT regulations are a vast and complex issue. While nothing could replace the personal advice of your accountant, we have compiled a list of links, ranging from official texts to pithy commentary. May they prove as useful to you in your research as they were to us! We wish you the best of luck in this endeavour!

  3. Warmest wishes from Wollzelle


    The Holidays are upon us — time for all to rest, relax, and enjoy the restorative company of friends and family.

    In accordance with our custom, the team will take a few days off to enjoy the festivities, from 22 December to 6 January. Rest assured however that administrators will continue to keep as close an eye as ever on the servers during that time. Ongoing projects will be put briefly on ice, like fine champagne, and will soon resume with a bang.

    Speaking of projects, we at Wollzelle wanted to thank you all for your continued support. You have made 2014 one of our best years ever, and we can’t wait to get started together on the next!

    We are once again celebrating the Holidays by donating to a cause that is dear to our hearts. This year, Wollzelle supports Integrationshaus, a Viennese charity dedicated to providing safety and support to refugees who have faced abuse and ill-treatment in their home country. Donations will be made in the name of our clients and partners, and we hope you can join us in this gift — in thought, if not necessarily in deed.

    May 2015 bring you joy, success, happiness, and fulfilment! Geruhsame Feiertage und einen beschwingten Start ins Neue Jahr!

  4. Say hello to Maiko, a new app from Wollzelle


    Today’s web thrives on a wide variety of devices and networks: laptops, phones, tablets, but also TVs, fridges, and glasses! All these devices have specific requirements in terms of bandwidth and image resolution. Serving the same content in such different circumstances can make your site slow to load, difficult to read, and expensive to download.

    Web designers need a simple solution to serve the right images to the right users, in the fastest, most economical way possible. This is how Maiko, our new image processing service, was born.

    Feeling overwhelmed? We haven’t even discussed Android yet!

    Maiko offers a comprehensive solution: it hosts, processes, and delivers your images transparently. Once your assets have been uploaded to Maiko, you can call them in the right size, resolution, and image format on-the-fly. Maiko generates the requested file in real-time, right from your source. It then distributes it to your end user over its worldwide full-SSD CDN.

    Big screen, big bucks, big Maiko! Please your Pro users…

    This makes changing images on your site as easy as changing a font size or a colour in your CSS. Change the source, and everything updates right away! Maiko accepts designer-friendly formats, such as Photoshop and Illustrator. It serves files in all standard formats, including the super-optimised WEBP. No intermediary exports and no alternate files means no confusion, no time lost, and no compromises in quality.

    The oh-so-cute Maiko is your site’s best friend. But she’s a ninja against bloat!

    Maiko’s intuitive web interface belies its advanced image processing engine, developed in-house by Wollzelle. If you can use the web, you can use Maiko. Fully documented URL parameters, and a complete JavaScript API, are available to all developers. This makes it a snap to integrate Maiko into your own web application. (A REST API is in the works, and coming soon.)

    Just how robust is Maiko? It is already powering high-profile sites like In January 2014 alone, it served 350+ GB of data! Today, by opening it to the general public, we are making this powerful new tool available to freelancers and agencies of all sizes.

    From upload to setup—touring Maiko in 3 minutes:

    Maiko is the latest addition to our portfolio of web applications. Fluxiom pioneered desktop-like interfaces on the web, and continues to offer innovative file management solutions. Maiko builds upon our data processing know-how, and offers the first true end-to-end responsive image management solution.

    We cannot wait to see what you are going to build with it!

  5. Study meeting at Wollzelle


    We all know that creators and artists build upon the accomplishments of their forebears, and we all say how important it is to encourage the creative urges of the younger generation. So when French students from the University of Marne-la-Vallée asked for a meet-and-greet session in our headquarters, as part of a grand tour of Viennese agencies, we immediately baked a poppy seed cake, and jumped at the opportunity!

    We were delighted to share our experience with this smart and energetic group of aspiring creative professionals. They filmed the session for their records, and were kind enough to post it on YouTube, where you will find the Video in all its unrehearsed, off-the-cuff glory.

    Our thanks and best wishes go out to Marianne Cardin, Karim Pierre Chabane and Célia, Julie, Nathalie and Diana. We hope they enjoy Vienna as much as we enjoyed meeting them! If you do happen to read French, we encourage you to read up on their adventures on their travelogue.

  6. Time for the Ho-Ho-Ho-Holidays at Wollzelle


    Can you believe it’s Christmas again? Neither can we, but the frost in the streets of Vienna does not lie, and neither does our calendar.

    Allow us, therefore, to open the festive season in traditional fashion by expressing our sincerest thanks for your continued trust, readership, and support. We at Wollzelle take pleasure and pride in serving you, and look forward to opening exciting new chapters together in the year to come.

    Speaking of serving and services, please note our office will be closed from December 21 to January 6, inclusive. Engineers will remain on call to monitor the servers, and ensure all applications are running smoothly, but our creative and consulting operations will be put on ice, while everyone gets a chance to spend time with friends and family.

    In 2013, we are proud to support Neuner Haus, a Viennese charity dedicated to helping the homeless. This will be in lieu of a more tangible gift, and we shall thus donate the funds in the name of our clients and partners. We hope you can join us in this effort in spirit, if not necessarily in deed.

    Before signing off fully for the year, allow us to recommend you keep a close watch on the blog in January. Our new service, Maiko, is already up and running, and is about to open to the public. (It will serve 400 GB of images in December alone, and that’s only the soft-launch.) And with our new site and the recently refreshed Fluxiom, we shall be able to rekindle this blog, keeping you abreast of interesting and surprising happenings in the worlds of communication, technology, and design.

    Once again, our warmest wishes for the Holidays, and the new year! See you in 2014! Habe die Ehre!

  7. Reddit for the gentleperson


    Reddit lies at the centre of today’s web. A watering hole for geeks, journalists, and trendsetters, it kindles everything from fashion fads to national security debates. Information flows so fast, and so deep, that it’s easy to miss: blink, and your bearings are lost, scroll, and you’ve missed a key comment…

    When Peter Purgathofer, the well-known technologist and educator, asked us to collaborate on a radically different Reddit client, we jumped at the chance. Our goals were threefold: provide an intuitive visual representation of the conversation, highlight contributions from friends and contacts, and facilitate voting. Simply put, we wanted to make Reddit useful again.

    Working with developer Matthias Tretter, Wollzelle tackled the user experience, the design, and the typography. The result is called Biscuit, and it’s available from the App Store today.

    Read, scroll, swipe: have no fear of losing your way
    Dive into Reddit’s rich database

    Built exclusively for iOS 7 on iPad, Biscuit uses an infinite canvas to lay out conversations, and their various branches, endowing each dimension with clear meaning. It invites users to explore threads visually, and to dive into each tangent, without ever allowing them to lose sight of the main topic.

    Comments from friends and contacts are automatically highlighted to emphasise trustworthy opinions. Last but not least, voting, the key ingredient of Reddit’s alchemy, is always but a swipe away.

    A complex engine ticks behind the scenes to enhance the user’s experience, always preloading, caching, and parsing to keep things fluid and up-to-date. Full Markdown support encourages active and constructive participation in the debate, by removing any barriers to the writing of complex comments. (And of course, it wouldn’t be a Reddit client without a ಠ_ಠ button!)

    By focusing on the conversation and its flow, and facilitating interaction with others, Biscuit hopes to turn Reddit’s swamp back into fertile ground for thought. It is an opinionated design, and one we are very proud of.
