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 responsibilitiesImplement 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.

Write and review code, tests and documentation, and help improve our development tooling.

Help keep the firmware within the memory, latency and power budgets of a low-power cellular modem.

Contribute to the firmware interfaces and test modes used in production test and certification activities.

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.

Work closely with system architects and hardware designers, giving firmware input on new RF related features.

Key Qualification and skillsMaster's degree in Electrical Engineering, Communications Engineering, Computer Science, or a related technical field.

3+ years of experience in embedded software development, preferably close to radio, RF or physical layer hardware.

Strong C program
