  • You’ll play a key role in building and running scalable marketing programs that directly support our commercial goals — from generating demand to improving conversion and retention.
  • This role combines strategic thinking with strong execution.
  • You bring a proven track record in growth marketing, a deep understanding of B2B SaaS dynamics, and a hands-on mindset to design, run, and optimize campaigns that deliver measurable results.
  • You’ll work directly with our Co-Founder and collaborate with our in-house Marketing Specialist, who supports execution.
  • Translate business goals into a clear, data-driven growth marketing strategy.
  • Define a repeatable system for demand generation and pipeline acceleration.
  • Lead the marketing roadmap and identify the highest-impact growth opportunities.
  • Work closely with Sales to align efforts and support revenue targets.
  • Own and optimize paid acquisition across LinkedIn, Google, and other relevant channels.
  • Design, launch, and scale multi-touch campaigns focused on lead generation and conversion.
  • Define key metrics and ensure consistent reporting.
  • Test and iterate quickly across channels, audiences, and offers to find traction.
  • Build automated lead nurturing workflows using HubSpot or similar tools.
  • Improve attribution, lead scoring, and campaign tracking.
  • Identify bottlenecks across the funnel and implement solutions to improve conversion.
  • Own and improve the performance of our website (Webflow) as a key acquisition and conversion channel.
  • Use data to increase visitor-to-lead conversion rates.
  • Ensure messaging, SEO, and landing pages are aligned with campaign and product goals.
  • Provide leadership and direction to our B2B Marketing Specialist.
  • Share growth best practices, frameworks, and training to build team capability.
  • Act as a marketing partner to Sales, Customer Success, and Product teams.

Requirements

  • 3+ years of B2B SaaS marketing experience , ideally in growth-stage or fast-moving environments
  • Have owned performance channels (LinkedIn, Google) and know how to scale them
  • Are confident using tools like HubSpot, Webflow, Google Analytics, and LinkedIn Ads
  • Have worked in a lean, fast-moving environment — and delivered results without needing a large team
  • Clear communicator who knows how to prioritize and align stakeholders
  • Comfortable coaching others while being able to jump in and execute when needed
  • Pragmatic, data-driven, and focused on outcomes
Benefits
  • A role with real impact in the transition to clean energy
