Description du poste

Field:Electronic hardware development,analogand digital circuit design, mixed-signal systems, and PCB design.

About the Role

We are looking for a Hardware Design Engineer to develop electronic devices combining analog and digital circuitry. The successful candidate will be involved in the full hardware development cycle, fromanalyzingtechnical requirements, defining system architecture, and designing schematics to PCB design and layout, prototype debugging, and preparation of manufacturing documentation.

We are looking for an engineer with hands-on experience inanalogand digital circuit design, a solid understanding of how these domains interact, and the ability to independently design PCBs while meeting signal quality, electromagnetic compatibility, and reliability requirements.

Location

This is a full-time, hybrid role based in Warsaw, Poland.

Responsibilities

• Design schematics foranalog, digital, and mixed-signal electronic devices.
• Independently design and layout printed circuit boards (PCB layout), including component placement, signal routing, multilayer PCB design, and stack-up definition.
• Designanalogsignal chains, including amplifiers, filters, measurement circuits, sensor interfaces, and signal conditioning circuits.
• Design digital signal chains based on microcontrollers, FPGAs, logic components, ADCs/DACs, and digital interfaces, including interfacing, clocking, and data transfer betweenanalogand digital subsystems.
• Ensure proper interaction betweenanalogand digital signal chains and minimize crosstalk, interference, and signal degradation.
• Design power supply, voltage regulation, filtering, protection, and decoupling circuits foranalogand digital components.
• Ensure signal integrity (SI), power integrity (PI), and electromagnetic compatibility (EMC/EMI).
• Apply best practices for component placement, grounding, return current paths, differential pair routing, and impedance matching.
• Select electronic components based on electrical characteristics, accuracy, noise performance, temperature stability, availability, and cost.
• Perform circuit calculations, simulations, and analysis ofanalogand digital circuits.
• Verify PCB designs before manufacturing, perform design rule checks (DRC), and prepare manufacturing files, including Gerber/ODB++, NC Drill, bill of materials (BOM), and assembly documentation.
• Bring up and debug prototypes, perform laboratory measurements, diagnose hardware issues, and implement corrective actions.
• Prepare technical and engineering documentation.
• Collaborate with embedded software developers, manufacturing teams, and other engineering specialists.

Requirements

• Degree in Electronics Engineering, Electrical Engineering, Radio Engineering, or a related field, or equivalent practical experience.
• Hands-on experience in schematic design and independent PCB layout.
• Strong knowledge ofanalogand digital circuit design, including the principles ofanalogand digital signal chain architecture and their interaction.
• Understanding ofanalogsignal chain characteristics, including gain, bandwidth, noise, offset, linearity, input/output impedance, filtering, and stability.
• Understanding of digital signal chain design, logic levels, timing requirements, clocking, and data transmission.
• Knowledge of ADC/DAC operating principles and the requirements for integrating them into mixed-signal systems.
• Understanding of interfacinganaloginput/output stages with data converters, including filtering, reference voltages, clocking, and noise performance.
• Solid knowledge of PCB layout principles, including component placement, routing, multilayer PCB design, stack-up, copper pours, grounding, power decoupling, and return current management.
• Understanding of parasitic capacitance and inductance, crosstalk, impedance matching, signal integrity, and electromagnetic compatibility.
• Experience with electronic design automation (EDA) tools such asAltiumDesigner, Cadence Allegro/OrCAD,KiCad, or equivalent.
• Ability to read and interpret component datasheets, reference designs, and application notes.
• Hands‑on laboratory experience using oscilloscopes,multimeters, signal generators, and other electronic measurement equipment.
• Ability to troubleshoot hardware issues,identifyroot causes, and justify technical decisions.
