RF Firmware Engineer

About the job

Join our Long-Range BU (Business Unit) R&D organisation and help build the firmware that brings Nordic's cellular IoT radios to

life. As an RF Firmware Engineer, you will develop the software layer closest to the radio: the code that configures, sequences,

calibrates and controls the RF transceiver so that every transmission and reception happens exactly when and where the

specification requires.

You will work in a tightly knit team of firmware, physical layer, RFIC and system engineers, taking features from specification

and silicon bring-up all the way to products deployed in millions of connected devices. The role combines low-level embedded

software craftsmanship with real RF and telecommunications understanding, and it gives you direct influence on how our next

generation of products perform in the field. Our technologies span e.g. LTE-M, NB-IoT, NTN, NR+, GNSS, Wi-Fi and eRedCap.

Key responsibilities

• Implement and maintain embedded firmware for RF transceiver control, such as radio state machines, gain and frequency control,

and TX/RX sequencing that follows the 3GPP frame and slot structure.

• Take part in silicon and board bring-up in the lab together with RFIC and physical layer engineers, and help debug RF

performance issues from register level up to protocol behaviour.

• Knowledge of cellular telecommunications, in particular 3GPP LTE/eRedCap/NTN concepts such as frame and slot structure, timing

and synchronisation.

• Experience with RF transceiver control, calibration or front-end control (antenna tuners, switches, PA/LNA control, MIPI RFFE)

is an advantage.

The ideal candidate is a curious and systematic problem solver who is not put off by a 3GPP specification, a schematic or a

register map. You enjoy chasing a problem across the boundary between hardware and software, and you communicate clearly with

colleagues from different disciplines. You are self-driven and pragmatic, able to prioritise and deliver in a dynamic environment,

and interested in understanding why a radio behaves the way it does.

Working at Nordic, you will be inspired and supported to develop yourself. Our teams enjoy a professional and informal working

environment. We value and encourage the continuous development of skills and expertise to the highest levels. We are proud of our

Norwegian heritage, our highly skilled international workforce, and our world-leading innovation.

We offer a variety of tasks and projects, and the possibility to work alongside some of the world’s most renowned experts within

their field. We encourage our employees to question the established and innovate while expecting professionalism, commitment, and

the will to learn.
