Job Description

Full job description

One employer, 3 locations, a unique working environment - excellent opportunities for your personal future

We are a young, owner-managed company that was founded 5 years ago by experienced business intelligence and data warehouse consultants and managers.

Our customers are international corporations in the retail, insurance, banking, media, telecommunications and industrial sectors. The typical clients at the customer are departments such as controlling, marketing & sales, purchasing and planning departments.

Communication with department heads, managing directors and board members is part of the typical project content of time2BI.

Leaving the beaten track, developing employees and their potential, strengthening strengths, demanding customers with technical and professional challenges that go beyond the standard, sharing successes, celebrating successes together - become part of our team!

this is us

Through our many years of experience in the consulting market for information management, we have learned that the balance between high performance and relaxation phases is one of the prerequisites for a positive team atmosphere.

At time2BI we ensure mandatory "on-the-beach" phases after a project that has required your full commitment.

We don't pay overtime, it doesn't even occur.

We address every team colleague, whether junior, intern or management, as "Du". Demanding customer projects in the TOP500, flat hierarchies with a lot of individual freedom to design your working environment require a high degree of personal responsibility.

At time2BI we celebrate our birthdays with gifts, meet up for jogging or in the fitness club. But we also set ourselves ambitious sporting goals, e.g. B. with participation in the Cologne Marathon 2018 as a company relay. In addition to the Christmas party, there is a summer party at time2BI, which has already taken place on a finca in Mallorca, for example.

We are all getting older - we take health restrictions into account when traveling and optimizing the individual workplace beyond the legal requirements.

We also know that children can become ill overnight and daycare centers can be on strike.

Your options with us

Best prospects for your further professional career in a team of BI and DWH experts at 3 attractive locations

We have confidence in the capabilities of our colleagues. We also document this with our salary model. Without exception, our colleagues are paid 100% of the agreed salary from day one.

We share success with the entire team - in a transparent process, our salary model offers each colleague a significant profit share based on individual performance, which increases annually depending on the company's affiliation.

With 3 locations, we ensure project assignments close to the workplace. And if it should be an assignment with travel activities, we ensure a time limit and end a project in cooperation with the customer if we cannot replace a colleague there after a certain time.

Our time2BI CAMPUS ensures that our team receives continuous and regular training offers. There is a fixed quota of 6 training days per employee and year in our company guidelines

anchored. In addition, every employee can think outside the box on 2 "brainstorming" days at events on overarching topics. Excellent work requires maximum support and professional guidance through internal or external training.

And beyond:

  • Comprehensive training by experienced colleagues
  • A mentor at your side ensures rapid integration into our team
