We are Leaply — an ecosystem of interconnected digital and physical products designed to help build healthy habits and improve quality of life. We’re developing a range of B2C products for global markets, including the US, Tier 1, Europe, and beyond.
 

This past June, we launched a new product — an app focused on habit-building with a subscription-based monetization model and a performance-first marketing approach through channels like Meta (Facebook, Instagram), Google, and TikTok. In just the first two months, we achieved positive unit economics and are on track to grow our revenue tenfold by the end of this year.

Our team is embarking on our third business venture together and has a proven track record of successful exits. We possess unique market insights that significantly enhance our chances of success — this isn’t our first time working with this business model, and we’ve already built products for this audience. Our core values are straightforward communication, quick decision-making, and aggressive, ambitious goals.
 

We’re hiring a Head of Engineering / Chief Technology Officer to lead our next phase of growth.
 

As we scale, we’re looking for a technical and strategic leader who will build a world-class engineering function across key domains — web, app, and AI — and pioneer a new frontier for us: hardware. You’ll have the rare opportunity to shape the company’s technological foundation, recruit exceptional talent, and define the gold standard for engineering and execution.

This is not just a tech role — it’s a business-critical leadership position. We’re looking for someone who can build systems, teams, and products — and help turn technical excellence into real-world value.

What you’ll do:

– Build and lead a high-performing engineering organization, rooted in excellence across web, mobile, and AI.

– Launch and scale our hardware engineering function, managing the full lifecycle of digital & physical product development.

– Hire, structure, and manage a world-class team of engineers — from early hires to future leaders.

– Define and champion an engineering culture focused on ownership, velocity, and innovation.

– Partner closely with product, design, and business leaders to co-own the roadmap and translate vision into scalable architecture.

– Ensure strong technical governance and decision-making aligned with long-term business goals.
 

What we’re looking for:

– A hands-on engineer with a strong technical foundation (experience in Back-End is preferable) and a love for solving complex problems.

– A mature engineering leader with a proven track record in hiring, growing, and managing engineering teams.

– Deep understanding of team dynamics, org design, performance management, and career development in technical teams.

– A product-oriented mindset and a collaborative leadership style — you're not just executing on specs, you're helping shape them.

– Comfortable operating in fast-paced, high-ambiguity environments, with a bias for action.

– English proficiency at B1+ level (we’re actively building a global team and hiring internationally).
 

Bonus points for:

– Experience in hardware startups: understanding the lifecycle of building and shipping physical products.

– Experience with AI / ML / data science systems — from prototypes to production (would be a plus)

– Previous experience in a high-growth product company or startup environment.
