About EVIQO

EVIQO is one of the fastest-growing smart EV charging brands in the US residential market, serving customers across the US, Canada, and Europe soon.

We are already among the Top-5 market leaders in the US in our segment and continue scaling rapidly.

Our mission is to build a category-defining EV charging brand that competes with major players like Tesla, ChargePoint, and Autel.

Our core product is a premium Level 2 smart home EV charger combined with a mobile app and software platform that allows users to monitor and remotely control charging, manage and optimize energy consumption, automate charging sessions, and reduce electricity costs.

With up to 50 Amps of charging power, strong hardware positioning, premium customer experience, and a powerful D2C + Amazon growth engine, we are building much more than just a charger — we are building a scalable international brand.

We operate at the intersection of hardware, software, IoT, e-commerce, D2C, and international growth.

About the Role

This is not a traditional Head of Marketing role.

We are looking for a strong hands-on digital marketing leader who is ready to build, execute, and scale digital marketing initiatives rather than manage a large internal team.

You will work directly with the founder and take ownership of EVIQO's marketing strategy, brand positioning, customer acquisition, and long-term brand awareness across the US and Canadian markets.

This role requires both strategic thinking and hands-on execution. You will not inherit a large in-house marketing team. Instead, you will execute marketing initiatives yourself, build effective marketing processes, and collaborate with external partners where needed.

We are looking for someone who enjoys rolling up their sleeves and getting things done. In turn, you work for the Amazon Best Seller brand and the product that obtained an Oscar award in design - Red Dot Award 2026, was mentioned in New York Times, Wirecutter, Motortrend, Yahoo and Car & Driver.

Although this role is titled Head of Marketing, we care much more about your ability to build, execute, and drive results than about your previous job title.

This role combines the responsibilities of a hands-on marketing leader, growth marketer, brand builder, and the founder's strategic marketing partner.

You will have a content producer, SMM, community manager and designer subordinated to you.

Key Responsibilities

• Own the overall marketing strategy and execution across digital channels
• Build and scale D2C customer acquisition across the US and Canadian markets
• Develop a clear brand positioning and messaging strategy
• Deeply understand customer pain points and continuously refine EVIQO's value proposition and messaging

• Ability to analyze complex products, identify customer pain points, and develop compelling value propositions (UVP)
• Strong analytical mindset with experience working with key marketing metrics (CAC, LTV, ROAS, Conversion Rate, etc.)
• Hands-on approach with the ability to independently execute marketing initiatives from strategy to implementation
• Experience working with external agencies, freelancers, and contractors
• Strong ownership mindset with excellent execution, prioritization, and organizational skills
• Upper-Intermediate+ English (ability to confidently communicate with US and Canadian partners - including some video calls).

Will Be a Strong Plus

• Experience in consumer electronics or hardware products
• Experience in home energy, smart home, automotive, or EV charging industries
• Experience building educational content ecosystems
