Are you a strategic thinker who wants to work on a growing product in one of the most exciting markets? Do you have a strong experience in product management or product ownership roles? If so, this opportunity is for you.

We’re looking for a strong Product Manager to take the lead on one of our projects. You’ll own the product direction — balancing customer needs, internal team capacity, and business goals.

This isn’t just a roadmap or task management role. It’s about leading collaboration across product, design, engineering, marketing, and sales to build something people want — and use.

Excited? Let’s see what it takes 💛

As a Product Manager, you will own:

• Product backlog and roadmap delivery.
• Customer insights and market research to guide priorities.
• User experience and performance tracking.
• Acting as the main bridge between product, design, engineering, marketing & sales teams.

We’re not just looking for a product thinker — we need a calm, clear, collaborative operator.

• You take ownership. You don’t deflect responsibility — you fix things.
• You give honest, respectful feedback — and you welcome it too.
• You don’t wait to be asked — you keep people in the loop before they need to ask.
• You don’t avoid hard conversations — you handle them directly but kindly.
• You write things down — because memory is fragile, and the team moves fast.
• You treat internal teams like marketing, sales, and HR as partners — not as distractions.
• You keep people in check without creating conflict.

What you will do:

• Own and prioritize the product backlog based on business goals and user needs.
• Propose product development directions, launch experiments, and make confident decisions to improve and grow the product.
• Collaborate daily with engineering, design, sales and marketing teams to deliver high-impact features.
• Define and track product milestones, KPIs, and user metrics like activation and retention.
• Gather and analyze feedback from demos, interviews, and support channels.
• Identify product gaps and market opportunities in partnership with marketing and sales.
• Monitor competitor offerings to inform product positioning and improvements.
• Use analytics tools (e.g., PostHog) to understand user behavior and propose enhancements.
• Communicate progress, blockers, and metrics regularly to stakeholders.
• Present roadmaps and feature demos internally and externally.
• Maintain organized documentation, meeting notes, access tools, and help create a knowledge base to support fast, effective work.
• Be initiative-taking, proactive, and able to challenge assumptions.

What you need to succeed in this role:

• 3+ years of experience in product management or product ownership roles.
• At least an Upper-Intermediate (B2) level of spoken English.
• Proven ability to lead projects from idea to shipped.
• Great communication skills — both in writing and in tough calls.
• Strong sense of accountability and clarity under pressure.
• Proficiency in using tools like PostHog, Notion, Jira, or similar.
• Experience working with remote teams and async processes.

Benefits and Perks:

• Small team, high ownership, fast execution.
• Business hours.
• Opportunity to work fully remotely.
• Inclusive international environment.
• Compensation in USD.
• Good bonuses for referring friends.
• Paid intensive training and probation.
• Work-life balance.
• Responsive management interested in your growth and long-lasting cooperation.
• Greenhouse conditions for self-development.
