We’re looking for a Product Manager for our partner company, Duomo.

Duomo is an app rooted in Christian values, helping people turn Scripture into daily habits and inner peace. We’re building a leading church-tech product for people seeking spiritual renewal.

To achieve this ambitious goal, we’re looking for a Middle Product Manager who will take real ownership of how Duomo evolves and how users experience the product.

What you’ll be responsible for

As our first PM, you will report directly to the Product Lead and:

• Own product areas end-to-end: problem discovery → solution → delivery → outcome.
• Drive the product development plan, balancing quick wins and long-term bets.
• Improve key product metrics (activation, engagement, LTV) through experiments and iteration.
• Translate user needs and insights into clear product goals and measurable outcomes.
• Work closely with Design, Engineering, and Content to turn ideas into business impact.

What we’re looking for:

• 3+ years of experience working as a Product Manager on a B2C product.
• You can break down a vague vision ("make the app more engaging") into a series of testable, measurable hypotheses.
• Before shipping anything, you understand what user behavior you’re aiming to change and how that change impacts key metrics like LTV, activation, or retention.
• Outcome-driven, not output-driven: You feel a physical itch when you see a feature shipped that doesn't move a metric or has a clear hypothesis.
• You thrive in an fast-paced environment with speed, ambiguity, and responsibility.

What will help you succeed in this role?

• You measure success by what changes for users and the business.
• You ask “what problem are we solving?” before building anything.
• You’re comfortable challenging ideas and proposing better alternatives.
• You can execute without heavy processes, but know when structure is needed.
• You’re hungry to grow and continuously improve as a PM.

Why Duomo

• You’ll work on a product with a clear mission and real values.
• You’ll help us transition from a content-rich app into a truly connected spiritual platform.
• You’ll be early enough to influence how product is done at Duomo long-term.

What we offer:

• Competitive salary;
• Significant impact on a rapidly growing business and contribution to how it shapes up;
• Ample career opportunities for ambitious growth and development;
• A possibility to attend internal, external courses, seminars and the access to a corporate library;
• Comfortable working environment. We provide all necessary work equipment for your role and serve complimentary breakfasts, lunches, and snacks in the office;
• 20 days of paid vacation, medical insurance and a variety of sports activities available for employees inside and outside the office.
