Our market‑leading advanced radios* are designed to help customers worldwide do their jobs better.

Role
In this post‑graduate role you will be part of Sepura’s Product Definition team. You will receive on‑the‑job training to help define the detailed behaviour of Sepura's advanced radio products and tools.

As you build knowledge and experience you will work with a variety of business stakeholders including Product Managers, Senior Development Engineers, System Testers, Customer Support Engineers and the wider business to:
* understand product requirements
* develop the requirements into a definition of product behaviour
* document the behaviour on behalf of business stakeholders
* maintain the documentation and incorporate change
In time you will become the custodian of the developed requirements, disseminate them to stakeholders throughout the organisation and become a go‑to knowledge expert on our products and features.
You will assist Product Owners (who are also part of our team), helping them understand product functionality. This also offers an excellent opportunity to train as a Product Owner.
Day to Day
Our customer base includes many different industries and markets around the world. Our complete TETRA and LTE solutions have been developed specifically for users in multiple sectors to face their critical communications challenges.
