Junior Product Manager ⚡
Help build the tech that powers millions. Join Onoff as a Junior Product Manager and grow your product career at the heart of our backend systems.
We’re looking for a hands-on, curious and technically-minded Junior Product Manager to join our Core and Traffic teams. These teams are the backbone of our platform, building and maintaining the backend systems that power multiple products across the company.
You will work closely with our Senior Product Manager and highly skilled backend engineers, helping turn ideas and requirements into well-defined, actionable tasks. Because this role supports backend development, a certain level of technical knowledge is required (or will be a significant advantage) — understanding APIs, system integrations, databases or backend workflows.
This is a unique opportunity to shape the foundation of our technology, support cross-team needs, and grow into a more senior product role over time. Our platform powers a set of products in the telecoms industry, processing millions of transactions daily. We’re scaling our core systems to support the next phase of growth.

Ensure increased engineering capacity is fully leveraged through clear task definition and planning.
Proactively identify opportunities to improve processes, alignment, and delivery efficiency.
🛠 What You Bring
Experience in product ownership, business or system analysis (backend/infrastructure experience is a strong plus).
Ability to write clear requirements, user stories and acceptance criteria for technical teams.
Comfortability reading API documentation, understanding request/response flows, and ideally being able to collaborate with engineers on system design trade-offs.
Familiarity with UML or process flow diagrams and ability to understand system behaviour.
Strong organisational and communication skills; ability to coordinate across multiple stakeholders.
Collaboration, eagerness to learn, proactiveness and comfortability in a fast-paced environment.
✨ Bonus Points For
