Business Development Principal

We're looking for someone who thrives in complex, high-value environments where building meaningful partnerships matters more than chasing volume. You'll identify organisations that need a long-term product development and manufacturing partner, uncover opportunities where Tharsus can create genuine value, and convert those opportunities into lasting customer relationships.

Working alongside our senior leadership, marketing, commercial and delivery teams, you'll have the autonomy to shape how we engage the market, identify priority customers and lead conversations that result in transformational partnerships.

What you'll be doing

• Identifying and qualifying new business opportunities across a range of sectors.
• Converting inbound enquiries while proactively creating opportunities through targeted outreach.
• Understanding prospective customers' commercial drivers, funding position, market opportunity and product-scaling ambitions.
• Leading customer engagement and collaborating with internal experts to build compelling solutions and proposals.
• Owning customer relationships through the proposal, negotiation and decision-making process.
• Representing Tharsus with senior decision-makers, industry partners and at key events.
• Strengthening Tharsus' reputation as the partner of choice for businesses scaling complex physical products.

About you

You may have built new business within a start-up or scale-up environment, grown strategic corporate accounts, or sold complex engineering, manufacturing or product-development services. Whatever your background, you'll be commercially astute, naturally curious and motivated by creating opportunities that genuinely deliver value.

You'll bring

• A proven track record of winning valuable new business.
• Strong commercial judgement and the ability to identify genuine opportunities.
• The confidence to engage and influence senior stakeholders.
• Excellent communication skills and the ability to simplify complex propositions.
• A collaborative approach that brings together expertise from across the business.
• The drive, resilience and independence needed to succeed in a highly autonomous role.

Why Tharsus?

As part of the privately owned Tharsus Group, you'll join a business with a reputation for innovation, engineering excellence and long-term thinking. You'll have the opportunity to work with ambitious customers, influence strategic growth and help bring the next generation of products to life.

If you're excited by the challenge of creating meaningful partnerships, opening doors to new opportunities and helping innovative businesses scale their products successfully, we'd love to hear from you.

Apply today and play a key role in shaping the future growth of Tharsus and the products that will define tomorrow.
