Senior Account Executive

London, UK

About Us

The world’s most pressing problem requires the world’s best talent to fix it, and here at CarbonChain we’re bringing together a superstar team to tackle decarbonization head on. We’re lean, scrappy and determined to make a massive impact by helping the world’s biggest emitters drive commercial wins by reducing their emissions. We see the climate challenge as a transformative opportunity for the global economy, and a rewarding career opportunity for those willing to take on the challenge in a rapidly growing market.

Our People

CarbonChain’s people are passionate about solving huge challenges, are driven by personal and mutual success, and take extreme ownership for their individual part of getting us to world-changing results. We live and breathe our values every day, and pride ourselves on creating a positive, inclusive and world-class environment for our talent to develop. We have MBAs and PhDs, and experience from various backgrounds leading huge initiatives. Our company includes individuals from some of the world’s best companies and scale-ups, but we know that there’s a lot we don’t know, and we’re hoping you can help fill that gap.

Key Responsibilities

Reporting directly to the Head of Sales, Account Executives at CarbonChain are “CEOs of their own businesses”, given the responsibility to develop their territory including building a plan and executing on that. They will work alongside Business Development & Marketing to design and implement a Pipeline Generation Plan, and will seek to close ARR on a predictable, efficient and scalable basis. They will also be part of our founding commercial team, so we expect this person to be driven both by personal results and invigorated by the idea of contributing to the foundation of the business, helping us iterate our strategy.

This position is for someone who can handle an ambiguous and rapidly changing environment, ramp up very fast on the technology and the climate regulatory market, and help direct the company’s efforts given your regular contact with prospects & customers.

Crucially, they need to be comfortable in uncomfortable situations and thrive on making great decisions quickly.

We need a driven Account Executive who has a track record of over exceeding quota for 6+ years and has the experience of working in a fast-paced start-up or similar business. They should be a Pipeline Generation (PG) wizard, constantly over exceeding outbound PG goals, and should have excellent sales fundamentals, and we’ll help you build on these skills. Experience in the sustainability/climate tech industry is a plus but not required.

Specific responsibilities include:

· Quota achievement against your ARR target (>$1M ARR)

· Creating sales opportunities through inbound and outbound prospecting

· Implementing the highest standards of data hygiene and always keeping the CRM up to date

· Forecasting accurately

· Helping us develop a new market or territory

· Holding the company values to the highest standard
