Job Summary
In this position, you will design wireless transceiver architectures, develop signal processing algorithms using MATLAB, and integrate them into system simulations to validate wireless systems at the PHY/L1 level.
Job Technologies
Your role in the team
- Definition and validation of the radio transceiver architecture as well as the associated interfaces within the SoC.
- Translation of wireless and product requirements into PHY-/L1 concepts, algorithms, interfaces, and verification plans.
- Development, integration, and verification of signal processing algorithms with MATLAB.
- Development, maintenance, and enhancement of link-level and system-level simulations for the radio system, particularly at the PHY-/L1 layer and, if relevant, via the interface to MAC/L2.
- Analysis and evaluation of design decisions regarding performance, implementation complexity, latency, memory requirements, chip area, power consumption, and robustness.
- Conversion of floating-point algorithms into fixed-point implementations for realization in ASIC or FPGA environments.
- Definition and further development of the hardware/software division between ASIC, firmware, and higher-level software components.
- Specification and coordination of interfaces between wireless algorithms, digital hardware, analog/RF blocks, and firmware.
- Support for system validation before and after silicon availability, including simulation, emulation, FPGA prototyping, lab testing, and silicon bring-up.
- Analysis of system-wide error patterns as well as identification and narrowing down of causes across algorithms, digital hardware, firmware, and RF/analog boundaries.
- Documentation of algorithms, assumptions, interfaces, simulation results, constraints, and design decisions in a comprehensible form.
- Identification, assessment, and resolution of technical risks throughout the entire product development cycle.
- Development and maintenance of reusable models, test environments, evaluations, and automations for simulation and verification.
- Active participation in shaping technical solutions as well as developing creative and pragmatic approaches to complex system issues.

Our expectations of you
Education
- Completed degree in Electrical Engineering, Communications Engineering, Microelectronics, Computer Engineering, Computer Science, or a comparable qualification.
- Several years of professional experience in Wireless System Engineering, digital communication, signal processing, or a closely related technical field; typically, you bring at least five years of relevant work experience outside of studies and internships.
Qualifications
- Proven technical expertise in wireless communication systems and signal processing, as well as the ability to translate communication theory into implementable algorithms and system architecture decisions.
- Very good understanding of modern wireless communication systems, especially OFDM as well as at least one other area such as MIMO, mobile communication systems, WLAN/Wi-Fi, DECT, or comparable broadband radio systems.
- Solid theoretical and practical knowledge of digital communication and signal processing, for example in several of the following areas: transmitter/receiver architectures, resampling and filtering, synchronization and timing recovery, parameter estimation, channel modeling and estimation, digital front-end design, or channel coding.
- You can analyze trade-offs between algorithmic performance, numerical precision, computational complexity, latency, memory requirements, and power consumption, and translate them into robust design decisions.
- You can systematically analyze system-wide issues and identify causes across multiple technical domains.
Experience
- Extensive practical experience with MATLAB for algorithm development, integration, simulation, and verification.
- Experience in the development or technical review of link-level and system-level models as well as in the critical interpretation of simulation results.
- Practical experience with fixed-point design, quantization effects, numerical stability, and implementation constraints in ASIC or FPGA environments.
- Experience in specifying and coordinating interfaces between algorithms, digital hardware, analog/RF blocks, and firmware.
- Nice-to-have: Experience with modern wireless standards such as DECT NR+, LTE/5G, Wi-Fi, Bluetooth, or Zigbee.
- Nice-to-have: Experience with RAN, PHY/L1, or MAC/L2 software stacks as well as the interfaces between protocol layers.
- Nice-to-have: Experience with the complete development chain of wireless algorithms - from system modeling, fixed-point implementation, FPGA/ASIC realization and verification, to silicon validation.
- Nice-to-have: Programming experience in Python, C, or C++ in addition to MATLAB.
- Nice-to-have: Experience with RF/analog and digital front-end impairments and their compensation, such as ADC/DAC effects, phase noise, IQ imbalance, AGC, synchronization, calibration, and equalization.
- Nice-to-have: Experience with encoding and decoding algorithms, such as Turbo codes, LLR processing, or comparable forward-error-correction methods.
- Nice-to-have: Experience with system verification through simulation, FPGA prototyping, lab testing, and silicon bring-up.
- Nice-to-have: Experience with defining register interfaces, control sequences, diagnostic functions, and calibration concepts for embedded or wireless systems.
- Nice-to-have: Experience in developing test strategies, reference models, automated regressions, or reproducible simulation environments.
- Nice-to-have: Experience working with RF, analog, digital, firmware, and system teams in a semiconductor, ASIC, FPGA, telecommunications, or wireless product environment.
- Nice-to-have: Experience in a start-up or scale-up environment as well as enjoyment of pragmatic decisions and short development cycles.
