• Get to work

    Our light and airy office is located in the center of Hamburg, in Eimsbüttel, a young and vibrant part of the city. Easy to reach by car and public transport.

    This is where we think, laugh, discuss and work in peace. As we are team players, we need the team to have physical proximity. However, we also offer flexible working hours, and the opportunity to work from home if required.

    Performances are the result of mental rather than physical presence. And only then, can we assess ourselves as a team and individuals.

  • Plan

    We prefer agile development processes like Scrum.

    We purposely do our resource planning offline, which makes it no less effective however: we use LEGO bricks to represent the allocation of employees to projects. One column per day, one row per project, and one color per employee. Clear, intuitive, haptic, modern.

    However, we also use a wide range of software tools. JIRA is our workhorse for task management and tracking, both classically and in agile mode. The most important information from this such as sprint progress, number of open tasks or deployment status is condensed and transparently represented on TV-based wallboards, so-called information radiators.

  • Work

    Our typical workplace, our peaceful, bright office is well-equipped: plenty of space, high-quality office chairs, modern technology (as desired - usually a Mac with two 27” screens).

    Our virtual tools also have to reflect the latest state-of-the-art technology. From the frameworks used (focus on Ember.js for the front-end, Symfony 2 for the back-end), the IDE (PHPStorm) and version management (Git-based with Bitbucket as front-end) to virtualized runtime environments (Docker).

  • Break

    Everyone deserves a break when they work hard. Time to clear the mind and satisfy hunger.

    The Osterstraße area offers a wide variety of lunch options. In terms of small snacks, we provide free coffee, cold drinks and fruit.

    And if you need to switch off for a little while, you can head up to our roof terrace if the weather is good. Or you can challenge a colleague to a match, as our conference table can also be used as a table tennis table.

  • Deliver

    A task is only complete once it has been delivered. Our CI server oversees the process of continuous integration and delivery. Each git branch push gets this started, and implements the automatic software tests, and only once everything is green, and a colleague has reviewed the code in the pull request, can the feature branch be merged (we use git flow).

    The build process then activates the necessary build tasks in order to compile and minify JavaScript/TypeScript and Sass, for example. This is followed by deployment in the respective environment (staging, production etc.). Fully automated of course.

    Release is online. Software tested and running. Happy customer. Happy developer.

  • Learn

    A rolling stone gathers no moss. Even more so for software developers. To prevent this from happening, we attach great importance to continuous learning.

    By learning on the job. By exchanging ideas, e.g. in the form of a Friday workshop. But also by taking part in activities independent from the job. E.g. we organise the Ember.js Meetup Group in Hamburg.

    Because there’s one thing that’s very important to us: we have to do what we do with passion. That’s the only way to deliver excellence.

  • Relax

    Half your life is spent at work. Sometimes even more. Therefore we have to make the time we spend together as pleasant as possible. Both at work, and also beyond for those who want to.

    Whether it’s trying out new sports together, with varying success (curling!), or a more relaxed end to the working week on the roof terrace with a barbecue and cold beer.

Data categories and origin of the data

The website of kaliber5 GmbH can also be used anonymously. Personal data (such as IP addresses) of users of the website are stored in temporary log files at most at short notice. When visiting the website, data (date, time, time spent, viewed pages, navigation, hardware and software used) of kaliber5 are anonymized by an external service provider for the anonymous analysis of user behavior. The anonymization takes place before the data is stored at the service provider.

Purposes of data processing

Should the user in certain cases provide kaliber5 with their personal data, they will be treated confidentially in accordance with the data protection regulations in force at the Company's registered office. If he sends an e-mail to kaliber5 or uses an online form on the kaliber5 website, the personal data provided there (eg name or e-mail address) will be used exclusively for correspondence with the user for the purpose of sending the requested information or for the other purposes mentioned in the individual form. If personal data is processed for a purpose not mentioned here, the user will be informed in advance.

Legal basis for the processing of personal data

All personal data is processed by kaliber5 in compliance with the provisions of the European General Data Protection Regulation (DSGVO), the Federal Data Protection Act (BDSG) and all other applicable laws on the processing of personal data. The respective legal basis for the processing of personal data depends on the context and the purpose of the data processing. The legal basis for the processing of personal data are "legitimate interests of the person responsible for handling the communication" as well as other "predominant legitimate interests".

Data access

Within the responsible person, access to personal data is only given to persons and entities responsible for the data concerned and for the respective transaction. For this purpose, clear business distributions and authorization concepts have been set up.

All personal data are also transmitted to service providers for the above purposes. This integration of service providers is also necessary in the context of the maintenance and administration of IT systems.

In addition, personal information may be transmitted to regulatory authorities or other recipients if required by law or by contract.

Data transmission to a third country

All personal data is processed only within the European Economic Area (EEA).

Measures for data security

kaliber5 uses state-of-the-art organizational and technical measures to protect the security of the data against destruction, willful or accidental manipulation, loss or access by unauthorized persons.

All dialog forms used on the website use SSL (Secure Socket Layer) encryption. This SSL connection protects all personal data in transit from unauthorized third parties.

All users are requested to use the dialog forms for data transmission, since unsecured e-mails with unencrypted data may possibly be acknowledged or changed by unauthorized persons.

Privacy rights of those affected

At the address listed above, any person concerned may request the information, correction, deletion and publication (in a standard, structured and machine-readable format) of the personal data stored about him. He can also claim his right to restrict the processing of the data.

Right to object

If kaliber5 processes users' data to protect legitimate interests, users may object to processing for reasons that arise from their particular situation. kaliber5 will then no longer process such personal data unless kaliber5 can establish compelling legitimate grounds for processing that outweigh the interests of the data subject, rights and freedoms, or the processing serves to assert, exercise or defend legal claims. If kaliber5 processes the data of a victim on the basis of his consent, this consent can be withdrawn at any time with effect for the future.

Possibilities for complaint

Affected parties have the option of complaining to the above-mentioned data protection officer or to a data protection supervisory authority. The data protection supervisory authority responsible for kaliber5 is:

kaliber5 deletes all personal data as soon as it is no longer necessary for the above purposes.

In particular, the legal duties of proof and retention, which are governed inter alia by the Commercial Code, tax laws and the tax code, are taken into account. This results in storage periods of up to ten years. If claims can be asserted against kaliber5 (legal limitation period of three or up to thirty years), personal data can also be kept for this time.

Using Google AdWords Conversion Tracking

kaliber5 is a Google AdWords customer and uses Google Conversion Tracking, an analytics service provided by Google Inc. (1600 Amphitheater Parkway, Mountain View, CA 94043, USA; "Google"). Google AdWords sets a cookie ("conversion cookie") on the user's computer if the user has reached the kaliber5 website via a Google ad.

These cookies are not for personal identification and lose their validity after 30 days. When the user visits certain pages while the cookie has not expired, kaliber5 and Google can detect that a user clicked on the ad and was redirected to the kaliber5 website.

All advertisers receive different cookies. Thus, cookies can not be tracked through the websites of advertisers. Conversion cookie information can be used to generate conversion statistics for advertisers. An AdWords customer learns how many people clicked on an ad and then took an action tagged with a conversion tracking tag. However, an advertiser does not receive information that personally identifies a user.

Any user who does not wish to participate in tracking may object to this use. To do this, he must prevent or disable the installation of the cookies by means of a corresponding setting in the browser. Thus, he is not included in the conversion tracking statistics.

The privacy policy and further information from Google can be found at:http://www.google.de/policies/privacy/

Information encryption and transmission

When using the contact form and all other forms, the transmission of the information uses SSL (Secure Socket Layer) encryption with a key length of at least 128 bits.

Handling emails

kaliber5 uses the e-mail address provided by the user to respond to the requested information by e-mail. As soon as kaliber5 sends an e-mail, the transmission is first tried encrypted (with the help of TLS encryption). If the recipient does not support encryption, we will send the email unencrypted. In doing so, kaliber5 uses the stored e-mail addresses exclusively for correspondence with the respective users and does not forward any e-mail addresses to third parties.

kaliber5 keeps emails related to a contract and does not send unsolicited emails. All unsolicited e-mails claiming to be from kaliber5 are fake and should be deleted.

All unencrypted e-mails are not protected against unauthorized access, falsification, etc. on the Internet. Therefore, the use of the contact form is recommended.
