About you (Who you are)

Skills & Experience

You have at least 10+ years of experience in fast growing marketing agencies and/or direct to consumer/e-commerce companies. This is by no means prescriptive, but we operate at the intensity of these types of organisations and are uncompromising on standards.

• Depth in understanding and network: You have a deep understanding of Japanese consumer behaviour, and bring an extensive network to solve nuanced problems within the market.
• Building high performing teams: You have experience building and scaling high performing teams (ideally from <50 to 200+) across topics such as workforce planning, hiring and onboarding, coaching and development, and performance management. You also have experience collaborating extensively with other leaders and supporting them on their development journey whether as peers, or as a manager
• A sharp eye, with a bold heart: You are confident in taking risk when directing creative to produce content that goes beyond boring and safe, stands out from the crowd and occasionally puts people offside, in the pursuit of the greater good and to ensure that the messages we communicate are heard, and felt.
• Creative problem-solver and detail oriented: You are highly organised, and not fazed by complex or ambitious problems. You are able to think critically, and break down big goals into smaller workstreams to empower others to act. You can design, manage and scale processes, adapting them as required at the various scales of the operation, and ensure a high degree of accuracy in your outputs. You can see the forest for the trees, and an expert systems thinker.
• Accountable to the numbers: You are highly literate both financially and in operational data, have a strong understand of the metrics that matter across a variety of business functions. You build systems that hold yourself and others accountable to the numbers.
• Communicate with clarity: You communicate incisively, honestly and often, leveraging the most appropriate mediums for different types of messages. You are able to synthesise complex concepts into clear insights and narratives that resonate with a broad audience
• Executional powerhouse: Strategy is simple, achieving it through flawless execution is what’s hard. Maintaining momentum will require good judgment and acting quickly within a fast-paced environment. You are not afraid to lead from the front, and get your hands dirty when it matters.

You understand that healthcare could be so much better and more accessible for millions of people worldwide, and are excited to relentlessly change the world.
• Craving for curiosity: You are self-motivated to understand the reasons behind the numbers. When metrics are off track, you are not satisfied until you have interrogated the system deeply to determine whether the issue is intermittent or persistent and requires thorough evaluation and improvement of the system. When metrics are ahead of track, you seek to understand whether it can be replicated across the business before celebrating the win.
• Calm, collected and resilient: You thrive in a fast-paced, chaotic, startup environment where you will need to balance quality with velocity and a MVP mindset.
