Job description

When On Project (Client Delivery): 

You'll contribute to and progressively lead workstreams on transformation projects (digital, operational, strategic). In practice, this means: 

  • Conducting stakeholder interviews, data analysis, and solution design 

  • Building executive presentations and facilitating workshops, with increased responsibility for structuring narratives 

  • Managing your assigned scope, from project timeline, deliverables and day-to-day client interactions 

At our office size, the jump from contributor to owner will happen faster than in it would be elsewhere. You will be encouraged and pushed earlier, directly supported by Senior internal decision makers.  

Between Project (Business Development & Internal): 

At most firms, consultants will spend years only seeing the delivery portion.  Here, you will be exposed to the full lifecycle of a consulting business (from finding the opportunity to nurturing the relationship that brings the next one), allowing you to build solid business acumen earlier than you would anywhere else. This includes:  

  • Contributing to proposal development and client pitches alongside Partners and Managers  

  • Researching new market opportunities and prospective clients  

  • Building and maintaining relationships with new and existing client stakeholders 

  • Develop thought leadership content 

  • Playing a role in recruitment activities, including initial candidate screening, early-stage interviews and onboarding

Qualifications

Must-Have 

  • 3-8 years consulting experience (strategy, management, or IT consulting) 

  • Native-level Japanese: full fluency in Japanese business culture and communication. JLPT N1 alone is insufficient 

  • Business-level English: daily use with global teams and C-suite reporting 

  • Bachelor's degree from accredited university 

  • Ability to operate independently and drive work forward without close supervision  

  • Willingness to take on projects outside your core expertise based on client and team needs  

Strong Plus 

  • Digital transformation project experience 

  • Business development or proposal writing experience 

  • Experience in Environmental Services, Financial Services, E-commerce, or Logistics 

  • Experience working in small/startup environments 

  • MBA or advanced degree 

Additional information

This Role Is for You If 

  • You are curious and proactive by nature, and you want to understand how the full business works end to end 

  • You learn best by doing it, taking on responsibility progressively, and getting direct exposure to senior decision-makers early 

  • You have an appetite for growth and are willing to step outside your comfort zone 

  • You want to build your own reputation and grow into a solid businessperson without relying on firm's brand name 

  • You are bilingual (native Japanese, business English) and thrive in global teams 

This Role Is NOT For You If 

  • You want Big4 brand name on your resume 

  • You need structured training programs and clear career frameworks 

  • You prefer to specialize in one industry/function only 

  • You work best with clear direction and defined tasks 

  • You want a predictable work-life balance regardless of client commitments 

  • Your Japanese is not native level: JLPT N1 alone is not sufficient for the client environment you will be working in  

Sia is an equal opportunity employer. All aspects of employment, including hiring, promotion, remuneration, or discipline, are based solely on performance, competence, conduct, or business needs.
