Job description

SiNIX are now looking for a driven and curious Digital Design Engineer to join our R&D hardware team located at our headquarters in Gothenburg, Sweden. You will develop advanced digital electronics for complex, high-performance systems where performance and reliability are critical. We are looking for engineers across experience levels, from early career to senior.

For this role, we expect you to take ownership of your work and enjoy solving challenging technical problems together with others. You need to have a business owner mindset and be able to adapt to many different company organizations.

If you are MacGyver, you have all the qualifications listed below. If you are a mere human like the rest of us and have experience in one or several of the fields and feel that SiNIX is something for you, please apply! We’ll provide you with as much duct tape as possible to excel in this role.

Responsibilities

Digital Board Design:

• Develop robust, high-performance digital designs on PBA level.

• Design boards ranging from signal processing platforms to computer platforms and data links.

• Realize solutions through component selection, schematic design and layout support.

• Design for high reliability in harsh environments, including derating, component selection and long product lifecycles.

High-Speed Design and Signal Integrity:

• Implement CPU/SoC, FPGA and DDR memory solutions on PBA level.

• Design backplanes and high-speed board-to-board interconnects, including connector selection and channel simulations.

• Run SI/PI simulations in tools such as HyperLynx or Ansys SIwave and translate the results into design and layout rules.

Mixed-Signal Design:

• Design mixed-signal front-end boards combining data converters, clocking and RF with digital processing.

• Integrate ADCs and DACs with digital processing on the same board.

• Ensure coexistence between digital, analog, RF and power sections.

System Architecture and Concept Studies:

• Work closely with system engineers, subsystem engineers and domain specialists, bridging system-level understanding into the hardware domain.

• Conduct conceptual investigations and studies addressing future solutions, architectures and design principles.

• Contribute to technical decisions and continuous improvement efforts.

Bring-Up, Testing and Verification:

• Drive board bring-up activities together with stakeholders.

• Perform test and verification activities, including test and integration scripting in Python and/or MATLAB.

• Characterize channels, interconnects and power distribution with VNA and TDR measurements, and correlate the results with simulations.

Full Product Lifecycle:

• Work across the full lifecycle, from early requirements to deployed and verified functionality.

• Provide production support and product maintenance.

PCB Design Tools:

• Utilize Cadence, Siemens or Altium PCB/PBA design tools for efficient hardware development.

Enjoy Working in a Well-Equipped Lab:

• Thrive in a well-equipped lab environment, conducting experiments and measurements.

Qualifications

• B.Sc. or M.Sc. in Electrical Engineering, Engineering Physics or a related field.

• Experience with digital electronics design, including CPU, FPGA and DDR memory implementation on PBA level.

• Hands-on experience with SI/PI simulation tools such as Siemens HyperLynx or Ansys SIwave, including pre- and post-layout analysis of high-speed channels, DDR interfaces and power distribution networks.

• Solid experience with PCB/PBA toolsets such as Cadence, Siemens or Altium.

• Experience with test and integration of PBAs using scripting in Python and/or MATLAB.

• Strong problem-solving skills and attention to detail.

• Ability to work effectively in a collaborative team environment.

• Fluent in English (written and spoken).

• Meritorious with experience of backplane design.

• Meritorious with VNA measurement experience, including S-parameter characterization, de-embedding and simulation-to-measurement correlation.

• Meritorious with experience of Cadence PCB/PBA design tools.

• Meritorious with experience of hi-rel electronics design for demanding environments, such as aerospace or space.

• Meritorious with knowledge of optical transceivers and links.

• Meritorious with experience in RF, analog and/or power electronics.

• Meritorious with mixed-signal experience (ADC/DAC).

• Meritorious with hands-on PCB layout experience.

Certain roles at SiNIX require security vetting, which means applicable verifications will be done in these recruitments.
