  • Experience with TypeScript and Node.js (our primary stack), or willingness to work extensively in this environment.
  • Experience with AI in developer tooling or internal systems.
  • Familiarity with agentic systems or orchestration frameworks.
  • Experience with production systems (performance, reliability, scalability).

• Technical Product Manager (AI Services team)

  RemoteWarsawPoznań

  22 000 - 28 000 PLN

  We are the company behind CKEditor – an open-source rich text editor used by millions of people around the world. We are part of Tiugo Technologies, a family of API-first developer platforms (CKEditor, TinyMCE, ButterCMS, Uploadcare) focused on content creation and digital collaboration.

  Description:

  As a Technical Product Manager, you will help shape how AI becomes a real product capability across CKEditor. This role sits at the intersection of product thinking, engineering depth, and developer empathy. You’ll work closely with engineers, designers, and business stakeholders to turn AI opportunities into product decisions that are useful, scalable, and worth shipping.

  When this role works well, teams move faster, product decisions get sharper, and AI capabilities feel like a real extension of the product rather than a layer added on top. You won’t just help define features. You’ll help define how we build in this space.

  You’ll work on the backend and platform layer that powers multiple products across CKEditor. This department includes the AI Services team, which focuses on agent harnessing, model management and evaluations, streaming, rate limiting, and permissions, as well as Cloud Services teams responsible for real-time collaboration infrastructure. What those teams share is a platform-first mindset: you need to care about APIs, service architecture, and the reliability that many products and teams depend on every day. On the AI side, you also need to understand what LLMs can and can’t do, and why that matters at the infrastructure level.

  If you have a stronger background with the product surface and the design - and would like to continue growing in that direction - take a look at our counterpart role: Technical Product Manager.

  Key responsibilities:

  • Help shape the product vision and roadmap for our features.
  • Drive prioritization day to day: make clear tradeoffs between user value, technical complexity, speed, and quality. Keep the team focused on what matters most right now.
  • Collaborate with engineering teams to translate business needs into technical requirements.
  • Manage the product lifecycle from conception through release.
  • Define and track product requirements, and ensure delivery of high-quality and scalable solutions.
  • Coordinate with sales, marketing, and support teams to maximize product success.

  To be successful in this role you need the following:

  • Engineers forget you're a PM. You come from a technical background (whether that's software development or another hands-on technical role), and it shows. You can read code, hold your own in architecture discussions, and understand constraints without needing them explained twice.
  • You ship, not just plan. Within 3 months, you'll be expected to be productive in the trenches. This isn't a role where strategy fills your calendar. You own the day-to-day scope and delivery alongside your engineering and design counterparts, and you move at the pace the work demands.
  • You're comfortable owning hundreds of small decisions, every day. High-level strategy will be covered by product and technical leaders, with your help. But the details are yours. You'll make judgment calls constantly, and you won't wait for permission to make them.
  • You take AI seriously and you lead well in high-stakes environments. AI is our top product priority right now. You understand how LLMs work, what makes a prompt engineering approach sound or fragile, and why model behavior matters to the product experience. You'll be in conversations with product leaders, technical leaders, and go-to-market teams, and you can discuss this work credibly with engineers and executives while driving clarity and momentum without formal authority.
  • You communicate clearly across very different audiences, in fluent English. You can explain a technical tradeoff to a non-technical stakeholder and an AI product decision to an engineer, on the same day, without losing either audience.

  Experience that helps:

  We care more about what you’ve accomplished than CV line items. If you’ve shipped products that users and developers love, and can discuss technical tradeoffs, we want to talk regardless of your education or exact years of experience. We’d love to hear about:

  • You’ve worked on platform or backend products that serve multiple teams or product surfaces. You understand the difference between shipping a feature once and building a capability others will depend on every day.
  • You can discuss prompt engineering, model behavior, evaluations, and operational tradeoffs without hand-waving. You know that AI quality is not just about picking a model; it’s about system design, guardrails, iteration, and measurement.
  • You’ve worked with APIs, service architecture, observability, permissions, rate limits, or other platform concerns that determine whether a technical product is reliable at scale.

  Why join CKSource:

  Our people are a huge part of what makes CKSource a great place to work! Aside from a great team, some of our benefits include:

  • B2B contract-based monthly remuneration is 22.000 - 28.000 PLN + VAT or its equivalent on the employment contract.
  • Flexible schedule and the possibility to work fully remotely.
  • Professional development resources (up to 5 days of additional leave and 6 000 PLN yearly).
  • LinkedIn Learning access.
  • Extra leave for Tiugo Day – our company’s foundation day and your birthday.
  • English lessons with a native speaker and an online language platform where you can learn English, Spanish, and German.
  • Access to a mental health and well-being platform with 24/7 dedicated psychological support.
  • Private medical care (Enel Med or Medicover) and Multisport card.
  • 26 days of paid leave for our contractors.
  • 2 weeks of paid parental leave for our contractors.

  Recruitment process:

  • HR interview, ~ 45 min
  • Interview with the Hiring Manager (Senior Technical Product Manager) and the Engineering Manager, ~ 1,5h
  • Interview with the Director of Engineering, ~ 30 min
  • In person deep dive task

CKEditor AI brings AI directly into the editor through capabilities like chat, review, and translation, helping teams create and improve rich text content without leaving their workflow. You’ll work on what is one of the most advanced rich text editing platforms on the market, combining AI capabilities with real-time collaboration for products where content is core to the user experience.

  If you have a stronger background in the platform layer, backend, and APIs - and would like to continue growing in that direction - take a look at our counterpart role: Technical Product Manager.

  • You've worked on enterprise-grade products where quality is non-negotiable and the details are what separate good from great.
  • You understand content processes: how teams create, review, and publish content, and you can see how a product decision in an editor ripples through an entire workflow. Experience with rich text editing, document-centric products, or real-time collaboration is especially relevant.
