Job description

Love building client relationships, solving business challenges and turning great ideas into opportunities for growth?

We're looking for a Senior Client Partner to lead and grow a portfolio of B2B clients, combining strategic marketing expertise, commercial drive and exceptional relationship skills.

You'll be the key client partner, working hands‑on with our broader team to develop smart, effective marketing solutions that deliver real business outcomes.

But this role goes beyond great client service. We're looking for someone who has a natural instinct for identifying opportunities, enjoys bringing new ideas to clients and has the confidence and commercial drive to turn those conversations into new business. We're also looking for someone who is a natural doer - familiar with what it takes to move the work from idea to delivery.

If you're a strategic thinker, natural relationship builder and love the thrill of winning work, we'd love to meet you. This role is based in Sydney, four days per week with a plan to grow to fulltime.

About Thinksmart Marketing (TSM)

We're a fast‑moving, smart‑thinking, award‑winning B2B marketing consultancy partnering with enterprise and scale‑up brands across APAC to drive growth.

Part consultancy, part agency, we combine strategic thinking, commercial understanding and creative excellence to develop integrated marketing solutions that deliver results. From brand strategy and positioning through to content, creative campaigns, ABM and demand generation, we connect the dots across the marketing ecosystem to help our clients grow.

We're a small, ambitious team of experienced thinkers and doers who value curiosity, initiative, collaboration and a healthy dose of humour. We work with some of the world's leading B2B brands across technology, financial services, professional services and other complex sectors.

The Role

You'll take ownership of a portfolio of clients, building trusted partnerships, leading strategic conversations and driving account growth.

What you’ll be doing:

• Lead client relationships: Build strong, trusted relationships with senior stakeholders, becoming a valued strategic partner who understands their business and challenges.
• Drive account growth: Take ownership of growing your client portfolio, proactively identifying opportunities, expanding relationships, pitching new work, and converting opportunities into revenue.
• Develop smart solutions: Work with clients and our specialist teams to shape strategic marketing solutions that solve business problems and deliver measurable outcomes.
• Oversee client & program success: Guide the delivery of high‑quality work, ensuring it’s delivered on time and budget, and client expectations, business outcomes and commercial objectives are met.
• Own commercial performance: Manage account plans, revenue forecasts, budgets and profitability, maintaining a healthy pipeline of growth opportunities.
• Collaborate and contribute: Work closely with our talented team, bringing fresh thinking, leadership and initiative to both client work and agency growth.

About You

You're an engaging, confident and commercially minded marketer who genuinely enjoys people and loves making things happen.

You'll bring:

• 8+ years' marketing experience, including at least 3 years in an agency environment, ideally with B2B clients.
• A proven ability to grow client accounts, identify commercial opportunities, develop proposals and win new work.
• Strong strategic marketing skills, with the ability to understand complex business challenges and translate them into effective solutions.
• Exceptional relationship‑building skills and the confidence to engage, influence and present to senior stakeholders.
• Solid commercial acumen, including experience managing client budgets, revenue forecasts and profitability.
• An outgoing, positive and engaging personality, with natural curiosity, energy and enthusiasm.
• An entrepreneurial, proactive mindset. You're comfortable taking ownership, bringing ideas to the table and rolling up your sleeves in a small, collaborative team.
• Above all, you're someone who clients enjoy working with, colleagues value collaborating with, and who gets genuine satisfaction from helping businesses grow.
• Make a real impact: Take ownership of your client portfolio and play a meaningful role in growing the agency.
• Interesting work and clients: Partner with leading B2B brands across APAC, tackling diverse marketing and business challenges.
• Work with experienced thinkers: Collaborate with a senior, talented team across strategy, creative and content.
• Opportunity to grow: Help shape client relationships, new solutions and the future direction of our growing consultancy.
• Flexibility and balance: Enjoy hybrid working and a genuine commitment to work‑life balance.
