Partnerships Lead

About Sirona Technologies

At Sirona Technologies, we are developing direct air capture (DAC) technology to remove CO2 from the air and combat climate change. Our next containerised plant is being built in Belgium and deployed in Norway. We're in the scale-up phase: we learn from the machines we run in the field, build that into the next generation, and move towards series production. Every iteration has to bring the cost per tonne down.

We're looking for a full-time, Brussels-based Partnerships Lead to sign landmark deals for Sirona and support the commercial team in building our growth engine from the ground up.

The role

As part of the Commercial team, you will report to our COO and our Head of Partnerships. We sell to large corporates through long sales cycles, where precision and relationship-building beat volume. This is a role where proactivity, strong relationship-building and flexibility turn leads into market-defining agreements, with massive impact on the company. We are a small, fast-growing company; every team member is expected to shape their role, proactively build a more productive mission-oriented company, take direct ownership and grow in the role.

Responsibilities

• The sales cycle is entirely yours: own your funnel of leads and manage deals across our whole sales cycle, with a strong focus on buyers' needs, from building relationships with senior sustainability decision-makers, to creating compelling DAC purchase proposals, to negotiating and closing contracts
• Own high-touch, buyer-centric events end to end, from pre-event outreach to follow-up and pipeline attribution, with original, out-of-the-box formats
• Contribute to our GTM strategy, building our AI-powered market segmentation tool and developing our marketing strategy as a core member of the (small) commercial team
• Manage our account-based marketing tool and AI-powered outbound engine, from account signals and enrichment to sequencing and personalization, to facilitate team-wide efforts to originate new relationships with corporate buyers
• Contribute to our informative content and inbound strategy (articles, webinars, newsletter, website, SEO, PR and LinkedIn, including for our CEO) so buyers come to Sirona to understand carbon removal

Requirements

• 2+ years in partnership building or growth, with proofs that you owned and closed large complex B2B deals
• Commercial judgment and hands-on B2B sales experience, ideally owning account-based or enterprise deals from first meeting to negotiation
• Demonstrate that you built outreach workflows, tools or campaigns yourself rather than briefing others
• Experience in building a playbook while running it in high-velocity environments, with a focus on fast iteration
• Hands-on with AI beyond a chat window: you build workflows with it and know where it adds value and where it doesn't
• Excellent writer, comfortable with technical topics and confident in front of senior buyers
• Versatile, highly organized and self-directed, comfortable switching between building and selling, with a strong sense of ownership
• Excellent written and spoken English: beyond being our working language, it’s key to building credibility with international buyers
• Strong interest in climate change and carbon removal
• Smart but humble, with a bias for action

Nice to have

• Experience in a climate tech startup, and/or ease in navigating discussions around carbon removal
• Experience in growth and marketing. Ideally we are looking for someone who would strengthen the team's skills and knowledge on driving an ambitious AI-supported marketing strategy, e.g. with design skills (Figma, Canva or similar)
• Hands-on experience with GTM tools like Clay
• Exposure to RFP or procurement-led sales cycles

What we offer

• Real ownership: you own your pipeline, shape the growth function and how Sirona shows up in the market, and help close deals with major corporates
• Direct collaboration with the founders and the commercial team, and a seat at the table on real commercial decisions
• You will work from our offices in Brussels, Belgium, with regular travel to events and customer meetings across Europe and the US (15–25% travel expected)
