Job description

We are the company that stands behind the spectacular success of CKEditor, used by millions of people around the world.

At CKSource we produce software components that other developers use to build their applications (WYSIWYG editor, file manager, document converters, etc.). Our flagship product is CKEditor 5 – an open-source, modern TypeScript rich text editor with a custom data model and virtual DOM – check our GitHub repository.

We are part of Tiugo Technologies, a launchpad for new developer platforms, helping software companies accelerate growth, increase operating efficiency, and scale their business. Tiugo’s current family of brands includes CKEditor, TinyMCE, ButterCMS, and Uploadcare. Together, our products power millions of software applications and websites – enabling content and communication for teams from Microsoft to NASA. You might not know our name, but you’ve probably used our software.

Your new role:

As a Technical Product Manager, you will play a key role in scaling up our product capacity and shaping the developer experience for CKEditor 5 – both for our open-source community and enterprise customers. You’ll work closely with our Platform team and collaborate with developers who build the foundational tooling and development environments that power CKEditor.

This role sits at the intersection of engineering and product, and we’re specifically looking for someone with strong technical experience (particularly in JavaScript ecosystems, SaaS, CMS, developer tooling) who can bring a product-oriented mindset to solve real developer pain points. You will contribute to initiatives like our CKEditor Builder and help us deliver intuitive, efficient ways for other developers to adopt, set up, and extend our software.

• Define and track product requirements, ensure delivery of high-quality and scalable solutions.
• Act as the voice of our developer users, both internal and external – understand their challenges, pain points, and feedback.
• Coordinate with sales, marketing, and support teams to maximize product success.

To be successful in this role you need the following:

• At least 3 years of hands-on software development experience (JavaScript, frontend frameworks, SaaS platforms):
• You are an ex-dev turned Product Manager,
• Or a developer with strong product thinking that is willing to convert to the product management path.
• Willingness to take up the challenge of working on products used by millions of users.
• Strong understanding of modern web ecosystems, open-source development, and developer experience.
• Product thinking: ability to see the bigger picture, understand business goals and user needs.
• Excellent communication skills – able to clearly express ideas, listen to different perspectives, and collaborate across teams.
• Comfortable leading discussions, presenting proposals, and driving consensus.
• Fluent English – spoken and written.

What would be nice to have:

• Previous experience as a Product Manager or Product Owner.
• Experience working on open-source projects, release processes or developer platforms like CI.
• Familiarity with content management systems or editing technologies.
