Founding Account Executive, US

About the RoleThis is the first US sales hire. The US is the biggest opportunity in front of us, and we expect it to become h2x's number one market. The whole company is leaning in.h2x has real traction across the UK, Australia, and New Zealand, used every day by some of the world's largest engineering firms. We've made the product changes the US market needs, and we already have an early customer base in the US. The go-to-market opens up now.There's a playbook in place from the markets we already sell in. It's the starting point, not the answer. The US buyer is different, the channels are different, and the competitive set is different. We need someone who can use what fits, throw out what doesn't, and shape the US version as they sell.You close the deals yourself. Inbound from marketing, outbound into the right accounts, discovery, demos, proposals, close.You're paired with a Solutions Engineer who handles the deep technical calculations during demos. You don't need to be the deepest MEP expert in the room. You do need to run the sale.h2x is a design platform purpose-built for mechanical engineers, with technical depth not matched anywhere else in our category. We aim to be the global standard for building services design. You'll work next to our founder, who lived this problem for years before h2x existed and knows exactly what's broken. MEP engineers, design firm principals and commercial contractors don't respond to generic SaaS playbooks. The reps who win here hold real conversations about how the product works, sit in demos with senior engineers and earn the room, and treat the sale as a craft.How We WorkWe value directness and simplicity. Short, clear answers to direct questions. We reach for tools, systems, and agents to scale ourselves rather than add headcount by default. We expect real craft in how we talk to engineers, not generic SaaS sales dressed in an engineering skin. We hire people who are excited about the work, enthusiastic about the customers, and a pleasure to be around.Key Responsibilities1.
