We’re changing the rules of the game. If you are not suitably prepared, it’s best you stay in your comfort zone.

Team First. No Ego

If your marketing ego comes in the XL size, sadly it won’t fit in our trophy cabinet. We are looking for a team player who is conscious of just how many people contribute to a single success story.

Coach Ability

We don’t need hour-long meetings and brainstorming sessions to give each other feedback. At Harbingers, feedback is given in the kitchen over a cup of coffee, at a desk, by means of Slack, Asana and by mail. It’s impossible to predict the direction it will be coming from next. However, we can promise you that the feedback will be substantive and constructive – it will refer specifically to your work and enable you to do it better.

Work Ethic

Working for a marketing agency is certainly not a picnic with sandwiches and tea. You will be given tasks to carry out within a specific deadline. Not to worry though, as you won’t be left to your own devices – your team will always be there to provide you with necessary support.


“I’ve got an idea!” – this is one of the most frequently heard sentences at HBGR. If after hearing an idea of your team member you fail to come up with 3 ways of putting it to use or improving it, don’t waste out time by applying.


“The impossible we do immediately. Miracles take a little longer.” If you tend to be satisfied with a meagre 100%, better give it a rest. When you join Harbingers, you must have an appetite for more!

If you still want to get to know us better

We always have justification for all the actions we undertake in our projects. If we do not invite you to one of the stages of the recruitment process, there will also be specific reasons for the above. We want to make sure that we work with people who understand the essence of Harbingers and share our core values.

Ania, Piotr and Kuba

The HBGR team comprises almost 40 people. Although it seems hard to believe, such outstanding individuals go by quite ordinary first names. The most common names are: Ania, Piotr and Kuba. If your name is in this list, your chances of successfully completing the recruitment process might have just become much more favourable. And if the opposite is the case, you might just have to be the best at what you do.

Carrot flute

Naturally, our heroes also like to pursue ordinary hobbies such as running, cycling or travelling; however, some of us are passionate about meditation, making instruments out of vegetables or tap-dancing. So don’t forget to share your passions when sending us your CV. Of course, only if you can outplay our after-work pursuits.

Relay race

We do not want to follow industry trends with blinkers on our eyes. Instead, we want to create and change these trends! That’s why we give you the opportunity to dedicate 10% of your working time to other innovative projects which are not linked to your field of expertise. To date, we have begun working on projects related to sports, charity work and music. Stay tuned!

Several things which make working much easier

A man does not live by work alone – at Harbingers, we are well aware of this fact. And since we spend several hours a day changing the face of e-commerce, we care about our development in its every aspect. Discover the benefits reserved for our #GameChangers!

We do not limit ourselves to one field of expertise. Under the Dream Team’s in-house initiative, you will be able to dedicate 10% of your working time to a separate, creative project.

We recommend English lessons to expand our marketing vocabulary, which – by the way – is already quite impressive.

Our team members and their families are provided with a comprehensive medical package. We do not take health-related matters lightly.

At Harbingers, we steer clear of rigid training budgets. In order to offer development opportunities to our specialists and managers, we provide them with in-house training workshops, external courses and the potential to participate in conferences.

Multisport card – to limit the devastating effects of a sedentary lifestyle.

Harbingers organises both informal and slightly more formal team building events where we like to sing together – even the songs you are embarrassed to admit you know.

Where others provide fruit once a week, in our kitchen you’ll find a variety of snacks and beverages all week long.

We also give you access to modern equipment, to allow you to work quickly and efficiently for the greater glory of Harbingers.

Other positives include flexible working time and the ability to work remotely. Anything to contribute to your effectiveness.

It is thanks to working with our partners that we are winning awards.

If we decide to
work with someone...

We guarantee access to a full range of modern marketing tools.

Black Friday – how to do it better?

How to gain in excess of 3000 B2B leads in 5 months?

Is it possible to obtain 3000 leads and 5000 fans on Facebook in the space of 5 months?

A well-thought-out strategy, planning of actions to be undertaken and a spectacular result – how did we manage to exceed the expectations of our partner and ours?

How to migrate your store safely without losing visibility
