Senior Digital Design Engineer - High-Speed Hardware

SiNIX; Göteborgs kommun; On-site; SEK 600,000 - 900,000; Full time

Job summary

SiNIX are seeking a driven Digital Design Engineer to join our R&D hardware team at our Gothenburg headquarters. You will develop advanced digital electronics for high-performance systems with emphasis on reliability and long product lifecycles.

Bring-up, testing, and full product lifecycle involvement are key parts of the role. We welcome engineers from early career to senior levels who can own their work, collaborate across disciplines, and adapt to diverse company structures.

Qualifications

• B.Sc. or M.Sc. in Electrical Engineering, Engineering Physics or related field.
• Experience with digital electronics design including CPU, FPGA and DDR memory 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 backplane design, VNA, RF/power electronics, ADC/DAC, hi-rel electronics, optics links, and PCB layout.

Responsibilities

• Develop robust, high-performance digital designs on PCB level.
• Design boards 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.
• Implement CPU/SoC, FPGA and DDR memory solutions on PCB 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 results into design rules.
• 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.
• Work with system engineers to bridge system-level understanding into hardware.
• Conduct conceptual investigations addressing future solutions and design principles.
• Drive bring-up activities, testing and verification including Python/MATLAB scripting.
• Characterize channels, interconnects and power distribution with VNA/TDR measurements and compare with simulations.
• Work across the full lifecycle from requirements to deployment and maintenance.
• Utilize Cadence, Siemens or Altium tools for efficient hardware development.
• Thrive in a well-equipped lab environment performing experiments and measurements.
