We are looking for a highly motivated individual to take charge of all paid media, with a focus on digital advertising. This role involves agile advertising planning (media plan), execution, and optimisation by quickly grasping the circumstances, trends, public sentiment, and daily life needs of Japanese consumers. The successful candidate will contribute to the growth and expansion of Octopus and the enhancement of the customer experience.

If the work of an "Octopus Digital Marketer" (which we will detail below), the"Octopus way," and the vision/organisational culture of Octopus align with the workplace and career prospects you are looking for, please contact us even if you do not possess all the skills and experience listed later. Let's have a chat first!

Things you should know about Octopus first:

Usually, this is where we would introduce Octopus as a company, but you may have already done some research by looking at our website. So, we will save the company introduction for the very end (with plenty of detail!) and first introduce some points that we want you to know - which are, in a sense, more important than the company introduction - as a potential future colleague.

We don’t use agencies.

We fundamentally do everything in-house that is physically possible: advertising, sales flyers, UX, development, media buying, etc. By doing so, we can thoroughly grasp and manage all stages of our corporate activities, enabling agile, flexible, and responsible work. You could say we are half "in-house agency," but the kind that doesn't require timesheets or suits.

We’re pretty obsessive.

We think about our customers a lot. A lot a lot. We answer emails from customers, we join in on social media (and I mean we, as leaders do), we think constantly about what makes great experiences, great stories and great reasons for people to join us. We observes, monitors, thoroughly researches society and people, and sometimes directly asks them to deeply consider "what people want right now."

Our daily work might feel, perhaps a bit dramatically, like racing at 200 km/h down an uncharted road with no map, no navigation, and only 50 meters of visibility ahead.

We have to be honest, we find that people from traditional businesses often struggle here. We don’t work to backlogs, we don’t write business cases but we prioritise effectiveness and efficiency above all else. Instead of adhering to Instead of adhering to plans crafted months in advance, we focus on what is needed now - dynamically adjusting priorities in an agile loop. We expect accountability without process, and responsibility without functional shoulder pads. We get stuff done by knowing what’s right, and sometimes that’s hard.

A Digital Marketer at Octopus is:

You’re a grafter, but you’re a smart grafter, you put effort where you know it delivers the most value - writing out an agenda for a meeting kills a little bit of your soul.

You've a burning desire to turn your skills to something meaningful. You enjoy the pace of the commercial world, but you’d rather not flog FMCG any more, you’d want to be delivering something more sustainable, digital experiences that the world and people genuinely need.

We’re looking for someone who knows their way around website and ad performance analysis, campaign optimisation, and acquisition/retention funnels. You can trot out some good metrics, but actually, what you really, really know is humans. You feel what a brand is. You get why people choose it (even when it seems illogical). And you’re just a little bit fascinated by why people make the choices they do in their real, chaotic daily lives- full of self-centered desires, love, loss, stress, and boredom.

About Us

"Octopus Energy" is an EnTech (short for Energy Technology) company founded in the UK in 2016. It has since grown to become the No. 1 electricity company by market share in the UK*1, providing affordable and environmentally friendly electricity to over 10 million customers in 18 countries worldwide.

The company launched its services in Japan in 2021 through a strategic partnership with Tokyo Gas. It is currently chosen by over 500,000 households domestically and is steadily growing at a pace comparable to its home country, having achieved a Google review score of 4.4. Furthermore, from 2022 to 2024, it was announced as the fastest-growing electricity company among Japan's top 40 electricity companies, with a growth rate of 1,137%*2.

One of Octopus Energy's strengths is its proprietary technology platform, "Kraken." Through cloud-based billing systems and the advanced utilization of data science, modeling, and AI, Kraken is redefining the possibilities and future of energy, making a significant contribution to the transformation of energy supply products and services mentioned above.

Upon a foundation supported by technology, Octopus Energy's agile and flexible business operations, combined with a corporate culture as a challenger and reformer, have led to many groundbreaking services.

At the same time, Octopus embraces the motto "Love and Power," a phrase that is the most frequently used within the company. We have a culture where all employees, regardless of job function, engage personally and carefully with each customer, supported by an operational and organizational structure that enables this. We take the lives and circumstances surrounding our customers as our own, imagine their needs, and provide heartfelt support, product/service development, and sales activities (Customer Love).

This might sound contrary to the pursuit of "efficiency" through technology, but it is precisely because advanced technology enables efficiency that we can provide personal, human-to-human customer service and establish a brand as an electricity company that customers become "fans" of.
