Team & Role
As part of the Editorial Tech team, we seek someone who wants to be deeply involved in the editorial product workflow , collaborating with multiple teams to help them build better products faster. You'll act as an enabler and an optimizer for these teams, removing blockers so they can focus on their work.
The role reports to the Editorial Tech team lead, with direct impact across the nine countries where we operate, and close collaboration with C-level executives and other leaders - including Product and Tech.
This is not purely a technical role;
it's a product position with a technical approach. We want a builder with curiosity, logic, and a passion for learning, not someone who only executes tasks.
Your Mission
Your mission is to develop the best solutions for the team so we achieve more ambitious goals faster and with higher quality. To do this, you must deeply understand the editorial workflow, from lesson conception to delivering the product to schools.
Your Daily Life
Learn deeply about our educational products and internal creation workflows, becoming an expert in the product creation journey here at Innovamat.
Partner with multiple product teams (Learning, Linguistics, Illustration, Tech, etc.) to improve the speed and quality of our workflows and develop new approaches to current solutions.
Own and maintain internal tools that will be the base of product building, ensuring they solve real problems and are intuitive, performant and aligned with business priorities.
Enable and train colleagues to use internal tools effectively; we don't stop just at building, we ensure the solution is correct and that everyone can use it effectively.
Coordinate with the multiple Product teams to prioritize and push improvements to all our tools and workflows.
Proactively participate in technology decisions about our systems. Not just execute requests, but help shape what we should be building and how.
Build fullstack tools from scratch: logic, API, MCP, agentic workflows, web clients, CLI clients, agent plugins/skills, infra, ...
Integrate what we build with our tools ecosystem, internal and external.
Present findings through presentations, memos, or workshops, and contribute to external communications when relevant.
Stay curious: follow AI and engineering practices, new methods, and the edtech landscape — always learning and bringing fresh ideas.
What We Are Looking For in You
Good fullstack basics. We mostly work with Typescript, Node, React and Postgres (among others). We value the ability to learn quickly more than a specific tech stack.
Experience integrating LLMs into real-world products and using AI as a daily tool to develop and design solutions.
Product mindset. You start with the problem rather than the solution, measure impact, and know how to say no to things that don't add value. You pause to consider the problem before taking action. You create prototypes to validate hypotheses with the team. You ensure that all solutions are successfully implemented, used correctly, and genuinely solve the problem.
You are comfortable with ambiguity and work in short cycles: hypothesis, prototype, feedback, and starting over.
You know how to communicate with non-technical stakeholders and translate their needs into solutions. You know how to help them work with new technologies and our tools.
Teamwork and communication. We are fortunate that our users are just two desks away, so you need to take advantage of that every day to provide the most suitable solutions.
Proactive and autonomous. You ask "why," not just "how," and take initiative to make things better.
Passion for education, our mission, and a genuine desire to help others learn.
You enjoy maths, logic, and problem-solving — puzzles excite you, not scare you.
Fluent in Spanish and English (Catalan is a plus).
Nice to Have
2–4 years of experience in fullstack engineering, or similar roles (ideally in SaaS or EdTech).
Experience taking products from a blank slate to reality and maintaining them, including everything that entails (design, development, infrastructure, CI/CD, monitoring, etc.).
Experience in building internal products.
Understanding of software architecture concepts for the AI era.
