About us

Celestia Technologies Group (CTG) is an international technology group based on research and development, innovation and deployment of high technology products.  Primarily, the group focuses on R&D, Design Services and Product Development for Aerospace, Defence, Telecommunications and Scientific markets.  There is a rich pedigree of Product Development in Antenna, RF and Modem design for different Satcom & Terrestrial Systems.

The team here at Celestia Technologies Group (UK) Ltd have embarked on a challenging programme to design innovative technologies for High Throughput Satellite communication system.  Part of this includes the well-publicised large contract with the European Space Agency (ESA) to develop a fully electronic scanning ground station, capable of tracking and communicating simultaneously with multi satellites.  A broad range of technical domains are being worked on including Antenna, RF, Signal Processing, Beamforming, Digital Design and Real-time Software.

Given the increasing needs, we are keen to expand our team and hire highly motivated, capable engineers with good inter-personal skills and a positive attitude to tackle the seemingly impossible design requirements.  We are an equal opportunity employer committed to building an inclusive welcoming work environment where everyone is happy, productive and able to maximize their individual potential.

Role & Responsibilities

  • Generate new topologies and architectures to achieve very challenging system requirements

  • Create floorplanning of entire layout and assist in on-chip layout

  • Create design and specification of on-chip blocks such as LNA, phase shifters, up/down conversion, modulators/demodulators (mixers), variable gain amplifiers, LO chains, Baluns, baseband filters, RF switches, attenuators, summing amplifiers and biasing circuits

  • Evaluate the designed on-chip circuits in the lab either in hand- or automated measurements

  • Discuss block and system performance with System Engineers

  • Prepare and participate in design, spec and layout reviews

  • Take ownership of your tasks; plan and execute in line with project needs

  • Document and disseminate your works in line with project wide expectation

  • Report to Technical (Project) Manager

Skills, Knowledge & Experience

  • 5+ years commercial experience designing RF solutions and key blocks such as phase shifters, analogue filters, mixers, LNA, PA, Synthesizers

  • Hands-on experience in the design of complex chips (e.g. transceivers, wireless sensors, PLLs or convertors)

  • Familiar with well-known RFIC design tools, such as Cadence Virtuoso and Assura as well as ADS and SystemVue from Keysight

  • Familiar with standard CMOS, SOI, SiGe, GaAS, GaN and BiCMOS technologies

  • Understanding limitations and solutions of practical RF circuits and packages; e.g., coupling effects, isolation requirements, track and substrate loses, antenna feed calibration, signal loss at interfaces etc.

  • Familiar with lab test setups using signal analyzers, VNAs, signal generators, digital oscilloscopes, power meters, etc.

  • Proficient in MS Office tools and competent working on either Windows or Linux

  • Masters or PhD degree in Electronic Engineering, Computer Science or similar

Please clarify if you require any Permit/Visa to work in the UK. We endeavour to respond quickly to all applications so if interested please submit your CV with a short covering note to jobs@celestia-uk.com.
