• Experience in FPGA high-level synthesis.

• Experience using, developing, or working with Embedded Linux.

​

Software and Simulation Tools

• Proficiency in MATLAB/Simulink.

• Familiarity with other programming and scripting languages such as Python or JavaScript.

​

Communication Protocols

• Experience with communication protocols such as UART, SPI, I2C, QSPI, Ethernet, and USB.

 

Control Systems and Power Electronics

• Knowledge of digital closed-loop control applications.

• Understanding of power electronics; integration within the grid is a bonus.

 

Your benefits:

• Flexible working schedules: You will be based in our modern London offices but will have the flexibility for hybrid work-from-home arrangements. Talk to us at the application stage about any scheduling preferences you may have. 

• Employee Option Plan: You get equity in IONATE, so as we succeed so do you. 

• Company Pension: A competitive, flexible, and sustainable pension product to help you plan for your future. 

• Career Development: It’s important to us that you have the opportunity for ongoing professional development and career growth. 

• Cycle to Work Scheme: Low carbon travel is important for everyone, so we have in place a cycle scheme to help you purchase a bicycle.

• Slow travel: We believe in a low carbon future, so if you wish to travel by a lower carbon method – but it takes much longer than flying - we will give you an extra 2 slow travel days per year
