      As a Senior Tax Consultant, you will focus on Swiss Individual Tax, working within a high-impact team to deliver comprehensive, tailored solutions that address the complex needs of our global clients. You will be entrusted with increased ownership and responsibility, leading client engagements, mentoring junior colleagues, and contributing to the development of innovative tax strategies.

      • You will have the opportunity to apply your technical knowledge to challenging cases and assist in delivering presentations to clients and colleagues.
      • You will lead complex tax consulting briefings with clients on intricate cross‑border assignments, providing clear, practical advice on Swiss tax and social‑security implications. You will build and maintain client relationships as the primary point of contact, coordinate with international teams on multi‑jurisdictional matters.

      What you bring
      • Strong technical knowledge of Swiss national tax laws and international tax principles, including social security regulations related to cross-border mobility.
      • Curiosity, proactive mindset with a willingness to take ownership and drive projects forward independently.
      • Excellent teamwork and communication skills—both written and verbal—with the ability to explain complex tax matters clearly to clients and colleagues.
      • Great analytical and problem-solving skills, with a keen attention to detail.
      • Proficiency in MS Office applications and familiarity with tax software and digital tools.
      • Ability to work effectively in a team-oriented, multicultural environment and fast-paced environment

      Your profile
      • Bachelor’s or master’s degree in law, business, economics, finance or similar
      • 3–5 years' experience in individual taxation (German: Natürliche Personen) and social security law, gained in a trust/fiduciary practice, tax authority, social security administration or consulting firm.
