Marketing Lead - Growth

Somerville, United States | Posted on 08/10/2026

Monaire is transforming how commercial buildings manage HVAC systems through AI-powered automation and insights. We combine sensors, smart thermostats, and machine learning to deliver massive energy savings, operational transparency, and sustainability impact.

We’re growing fast across commercial and enterprise portfolios — and we’re looking for a marketing leader who can build and scale our demand generation engine.

You’ll own a part of Monaire’s funnel end-to-end — strategy, execution, and optimization. This is not a “manage the agency” role. You’ll architect the systems, test relentlessly, and double down on what works.

• Own the strategy — build and continuously optimize a high-ROI funnel that converts awareness into qualified pipeline across commercial building owners, operators, and C-suite facilities teams.
• Design and test campaigns across channels — email, cold outreach, physical mailers, events, digital ads, and content. Find creative angles that cut through.
• Develop the ICP and messaging framework — distill Monaire’s value into simple, sharp narratives that speak to cost savings, operational reliability, and sustainability.
• Run experiments like a scientist — track metrics, analyze conversion paths, and use data to iterate weekly.
• Collaborate cross-functionally with product, sales, and customer success to align messaging and qualify inbound leads.
• Own marketing analytics — instrument the CRM, funnel tracking, and reporting dashboards to identify bottlenecks and double down on what moves the needle.
• Build the foundation — establish our playbook, nurture sequences, and partner ecosystems so we can scale with minimal friction.

You’re a hybrid: analytical and creative, scrappy and strategic. You’ve built marketing funnels before, preferably for a B2B SaaS or climate/IoT company, and you thrive in zero-to-one environments.

• 5+ years in marketing, growth, or demand gen — ideally in B2B SaaS, cleantech, or IoT
• Demonstrated success designing and optimizing multi-channel campaigns
• Proficient in CRM analytics, and A/B testing tools
• Strong copywriting instincts and an ability to translate technical value into business ROI
• Bias toward execution: you test, learn, and iterate faster than others can plan
• Have experience selling to facilities, operations, or energy management professionals
• Have built inbound systems from scratch (tools, workflows, automation)
• Can code in SQL or build dashboards to self-serve your insights
• Have worked in an early-stage startup or energy/proptech environment
• Mission-driven:
  Reduce carbon emissions and operational costs for the built environment
• Early ownership:
  You’ll define how Monaire grows
• Fast feedback loop:
  Your campaigns will have visible, immediate impact on revenue
• Work with a sharp, motivated team of engineers, designers, and operators building category-defining tech
• Competitive base salary and meaningful equity
