Overview: Air pollution is the world’s largest environmental health risk. Every pollution spike has a source — and EMSOL is the technology that finds it. We don’t just monitor emissions; we identify exactly who or what is causing them, giving our clients the evidence to act. From Guy’s Hospital to the London Underground, construction sites to city streets, our platform turns invisible pollution into clear, targeted action.

We’re looking for an Account Executive to join our commercial team and play a central role in growing that impact. This is a hybrid role combining new business development with hands-on account management — you’ll own your accounts end-to-end, from winning new contracts through to renewals, expansions and ongoing client engagement.

We want a confident, experienced operator who already knows how to build a pipeline, close deals and manage customer relationships in a B2B environment. Ideally, you’ll bring sector knowledge from construction, environmental compliance, air quality or sustainability — but the right person with strong B2B technology sales experience and genuine curiosity about our market will also thrive here.

You’ll work closely with our CEO, CTO and a fellow Account Executive in a small, collaborative team where your contribution has a direct and visible impact on the business — and on the air people breathe.

• Revenue Growth: Build and manage a robust sales pipeline to consistently deliver against quarterly revenue targets. Identify and close new business opportunities, particularly in construction and environmental compliance — sectors where pollution is a daily operational reality and our technology delivers measurable results.
• Account Ownership: Take full ownership of a portfolio of allocated customer accounts. Drive renewals, expansions and upsell by understanding each client’s operations, sustainability and compliance objectives, and procurement process. Your accounts won’t just be names on a list — you’ll know their sites, their challenges and their targets.
• Client Engagement: Maintain regular, proactive engagement with clients through review meetings, data-led reporting and ad-hoc on-site visits. Be the trusted point of contact who keeps EMSOL front of mind when budgets and priorities shift. The best opportunities come from relationships, not cold calls.
• Market Development: Help shape EMSOL’s positioning and go-to-market approach by feeding back market intelligence, competitor activity and client needs to the leadership and marketing teams. You’ll have a seat at the table in a business that’s actively building a scalable GTM strategy.

• Sales and Business Development: New business accounts, especially the major top 100 construction firms, are a key focus for the business to win and nurture.
• Manage the full sales cycle from lead qualification through to proposal, negotiation and close.
• Conduct product demonstrations of the EMSOL platform, the associated air quality and environmental data, and the service delivery process we adopt to help prospective clients with their sites and projects — including real-world mitigation options.
• Develop relationships with key decision-makers and budget holders, particularly in sustainability, procurement, estates, quantity surveying and project management functions.
• Be prepared to get on site (hard hat and high viz provided) to discuss projects and equipment siting, and support our installation engineers with contacts and access.
• Maintain an accurate, up-to-date CRM pipeline with reliable forecasting.
• Work with our SDR function and marketing team to convert inbound leads and support outbound campaigns.
• Attend industry events, conferences and client sites, and present EMSOL case studies and product positioning accordingly.

• Account Management and Customer Success: Our consistent growth comes from existing clients. These customers need attentive account management, proactive support and a constant focus on adding value.
• Own and manage a portfolio of active customer accounts, ensuring high satisfaction, retention and growth.
• Deliver regular account reviews, monthly and quarterly reporting, and proactive engagement to surface new opportunities — some contractual, but mainly driven by good account management and creative use of data.
• Support new project onboarding, ensuring a smooth transition from sale to deployment in coordination with our technical operations team.
• Manage contract renewals and negotiate terms that protect margin and strengthen long-term partnerships.
• Coordinate with operations on hardware logistics, installations and support requirements for your accounts. This is a vital element of the role — looking after and understanding our customers includes delivering on contracted or self-imposed SLAs for response times, fixes and availability.

• Data and Insight: You don’t need to be a scientist, but you will learn to read the data that drives our clients’ decisions — and that’s what makes the conversations genuinely interesting.
• Contribute to emissions source tagging and data interpretation for construction and lower-complexity accounts, using EMSOL’s platform to build the insights that underpin client reporting.
• Develop sufficient understanding of air quality and noise data to hold credible, consultative conversations with clients.
• Provide structured client feedback to site operations, and always feed back any platform or product issue — however small — to the engineering team or CTO to support continuous improvement.

• Invoicing and Commercial Administration:
• Raise invoices and chase purchase orders for your accounts, working with finance on payment terms and collections where needed.
• Keep commercial records accurate and up to date, including contract values, renewal dates and expansion opportunities.

• At least 3 years’ experience in a B2B sales or account management role, ideally within a technology, SaaS or IoT business.
• Proven track record of meeting or exceeding revenue targets in a startup, scale-up or SME environment.
• Experience selling to enterprise or public sector clients, with an ability to navigate multi-stakeholder procurement processes.
• Strong commercial instincts: comfortable with proposals, pricing, negotiation and contract management.
• Confident communicator who can present to senior stakeholders and build lasting relationships.
• Self-starter who thrives with autonomy and takes ownership of outcomes.
• Proficient with CRM tools and comfortable working with data and reporting platforms.

• Sector experience in construction, environmental services, air quality, sustainability or environmental/engineering consultancies.
• Familiarity with environmental compliance frameworks, Net Zero targets or ESG reporting.
• Experience with IoT hardware and software solutions, including deployment logistics.
• Existing relationships or network within relevant sectors.
