Job description

About CLER

At CLER, we're redefining clean air. CLER is a deep-tech start-up that is revolutionising global air purification. Our cutting-edge, filter-free purification technology delivers ultra-clean air while requiring no maintenance, consuming less energy, and delivering a much more sustainable solution.

99% of the world’s population breathes air that fails to meet WHO guidelines, causing more than seven million deaths each year.

Indoor air quality is often 2–5x worse than outdoor air, even though we spend 90% of our lives indoors.

CLER's technology is backed by smart Swedish engineering and rigorous innovation. We believe in creating effortless, reliable air quality solutions that work for everyone, without compromise.

We aim to become the new global standard in air filtration. Our ambition is to redefine how the world cleans its air - by cutting waste, reducing CO₂ emissions and protecting public health.

About the Role

As Growth Hacker at CLER, you will own the execution of growth experiments, lifecycle marketing and funnel optimization across our markets. Your mission is to accelerate customer acquisition and activation through rapid testing, automation and smart, data-driven marketing.

This is a hands‑on role where you’ll run fast experiments, improve conversions and activate leads, working closely with sales and marketing to turn insights into measurable growth.

What you will be doing

• Run rapid weekly growth experiments across channels, landing pages and messaging

• Build and optimise landing pages and run CRO tests

• Implement and scale marketing automation: email flows, lifecycle campaigns, activation and nurture

• Support paid acquisition by running experiments and optimising key steps

• Identify and validate scalable channels to reach B2B buyers in each market

• Collaborate with the marketing team on messaging, content and GTM to ensure consistent funnel performance

• Work closely with sales to increase lead activation and shorten sales cycles

• Analyse performance and own dashboards for key growth KPIs (activation rates, conversion rates, CAC drivers)

Whom are we looking for

• 2–3 years experience in growth/performance/lifecycle/CRM roles

• Strong analytical mindset with a bias for experimentation

• Comfortable running tests independently in tools like GA, Framer, CRM etc.

• Hands‑on doer who iterates fast, learns fast, and doesn’t wait for perfect inputs

• Experience with automation and lifecycle marketing

• Experience with paid channels is a plus, not a requirement

What We Offer

• Join an ambition deep‑tech startup at an exciting global expansion.

• Opportunity to grow and develop your product marketing skills in a dynamic environment.

• Centrally located offices in Stockholm

• Most importantly - Making a true impact for the world - contribute to cutting waste, reducing CO₂ emissions and protecting public health through better air quality.
