Milton Keynes
Cesium UK – Engineering /
Full-time /
On-site
At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.
CesiumAstro designs and delivers scalable products from discrete modules to complete software defined payloads that work out of the box. The integrated product line ranges from single-beam downlink solutions to multi-beam, full-duplex communications payloads.
Our state-of-the-art products result from our ability to solve complex and challenging design problems. To enhance our team we are looking for ambitious, high-calibre engineers with experience in complex Digital Signal Processing (DSP), communications systems, and control systems algorithm design, targeting high-speed efficient digital implementation in FPGA and ASIC. Strong mathematical skills and a willingness to innovate and ”think out of the box” are essential for the role. The successful candidate will be part of a team delivering complex modem and data processing solutions for state-of-the-art communications systems.
JOB DUTIES AND RESPONSIBILITIES
- The research and design of fast and efficient hardware realisable DSP algorithms to implement functions such as filters, equalisers, timing/carrier recovery loops, multi-rate structures & FFT processing engines.
- The development of models to provide real life stimulus for testing the developed algorithms, including phase and Gaussian noise, non-linear RF effects, Doppler, multipath and other such channel impairments.
- The development of both floating and fixed point models in MATLAB, Python and C/C++ to the extent that data from the fixed point model can be directly used to accurately verify the functionality of the VHDL hardware realisation.
- The successful candidate will be versatile and proactive, a clear communicator and team player with good inter-personal and social skills. They will be capable of generating accurate and concise documentation and design notes, and be able to disseminate critical information and interact with the design team.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
- A Bachelor of Science (BS) or Master of Science (MS) degree in Electrical Engineering or Computer Engineering from an accredited university or institution.
- It is envisaged that the successful candidate will have a minimum of 4 years of relevant experience.
- A strong background in Wireless Communications, with theoretical knowledge of advanced concepts in DSP and digital communication systems, and a detailed understanding of wireless modem design.
- Knowledge of the real-time implementation of complex DSP in both hardware and software.
- Strong modelling skills using MATLAB, Python and C/C++ . Use scripting languages to achieve higher performance and improve testing and productivity through automation.
- Ability to partition design problems and to define block-level hardware architectures, while optimising the designs for area, speed, and power to meet system requirements. Good knowledge of VHDL is essential.
- Competence with MS Office tools to present technical information and generate concise reports.
PREFERRED EXPERIENCE
- Experience of FPGA development using VHDL, simulation, and top-level integration particularly using Xilinx design tools (Vivado)
- Good understanding of well-known Wireless Communications standards, in particular the DVB-S2(X), DVB-RCS(2) and CCSDS standards.
- Understanding of digital and analogue hardware design with some hands-on laboratory experience of bringing-up and validating designs, utilising various lab equipment.
- Knowledge of VITA-49.2 protocols
- Knowledge of the commercial landscape for
- Proven track record of on-time and high-quality project delivery
- Experience working in both start-up environments as well as larger technical organization
