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.

Let's build the next big everything together!

We are building a digital orthodontics platform with interactive browser-based 3D tools.

This role is primarily focused on frontend and 3D development with TypeScript, Angular, Three.js, and WebGL, with Node.js full-stack development as a secondary responsibility. You will build interactive tools for viewing, editing, and working with complex 3D models directly in the browser.

     You Are

• A software engineer with demonstrable experience building interactive web applications through commercial work, substantial personal projects, open-source contributions, or similar production-quality work.

• Able to work productively with Angular, including components, services, dependency injection, forms, routing, and application state.
• Experienced with RxJS or comparable reactive and asynchronous state-management patterns.
• Experienced with Three.js or a comparable WebGL-based engine, and ready to work directly with Three.js.
• Comfortable working with scenes, cameras, renderers, lights, meshes, materials, and render loops.
• Experienced with BufferGeometry, vertex attributes, index buffers, normals, typed arrays, and binary mesh data.
• Comfortable with 3D mathematics, including vectors, transformation matrices, local and world coordinate systems, rotations, and quaternions.
• Able to implement interactive 3D behavior such as raycasting, object picking, dragging, surface-constrained movement, camera controls, and object transformations.
• Familiar with triangle meshes, bounding boxes, spatial acceleration structures, collision or proximity checks, and common mesh edge cases.
• Able to work with 3D formats such as STL and understand model loading, coordinate systems, units, normals, and transformations.
• Able to profile and optimize browser rendering, CPU usage, GPU resources, and memory when working with large meshes.
• Familiar with Web Workers, ArrayBuffer, transferable objects, or other approaches for keeping expensive work off the main UI thread.
• Comfortable building and consuming REST APIs.
• Experienced with Node.js and Express, or a comparable backend stack.
• Familiar with file uploads, asynchronous jobs, persistent workflow state, authentication, validation, and error handling.
• Able to write unit, API/integration, and end-to-end tests.
• Familiar with Git workflows, pull requests, code review, and collaborative development.
• Comfortable taking ownership of AI-generated code by reviewing, testing, debugging, and validating it before delivery.

Angular experience is strongly preferred. Candidates with strong React or Vue experience may also be considered if they have substantial browser-3D expertise and can become productive in Angular quickly.

     
     Will Be a Plus

• Experience with three-mesh-bvh or similar BVH/AABB acceleration structures.
• Experience implementing mesh collision detection, proximity checks, or closest-point queries.
• Experience with mesh editing, contour manipulation, cutting planes, or CAD/3D-viewer tooling.

Advanced C++ or machine-learning expertise is not required. You will collaborate with engineers responsible for native geometry processing and ML services, but you should be able to understand their inputs, outputs, coordinate systems, and integration requirements.
 

     What We Expect from You

• Use modern AI development tools to work faster while remaining responsible for the correctness and maintainability of the resulting code.
• Make pragmatic engineering decisions that help us deliver quickly without creating unnecessary complexity.
• Investigate unfamiliar parts of the system independently and communicate important assumptions or risks.
