Senior PCB Design Engineer

About the Role

Transforming concepts into functional products requires a strong understanding of electrical fundamentals, physical constraints, and manufacturing realities. The PCB is the physical backbone of any hardware product, defining electrical performance, reliability, thermal behavior, manufacturability, and ultimately, the product's form factor and cost. This role is responsible for the design, validation, and manufacturing readiness of PCBs used across CynLr's products. The Product Design team will be your internal customer.

Key Responsibilities

• Supporting CynLr’s Product Design team with all Schematic, Layout, Library management, and hardware development.
• Translating system-level and schematic designs into production-ready PCB layouts.
• Defining board stack-ups, layer counts, and material selections based on electrical and mechanical requirements.
• Performing component placement and routing with focus on SI, PI, EMI/EMC, thermal, and mechanical constraints.
• Preparing and releasing manufacturing and assembly documentation for prototype and production builds.
• Supporting electrical bring-up and validation of manufactured PCBs.
• Debugging board-level issues in collaboration with system and firmware teams.
• Interfacing with PCB manufacturers, assembly vendors, and component suppliers to ensure successful execution and timely delivery.
• Acting as the PCB design knowledge base for design engineers and freshers.
• Contributing to system hardware design involving high-speed interfaces like USB, EtherCAT, PCIE.
• Designing and deploying PCBs for embedded systems.
• Designing evaluation boards for motor, encoder, camera, and similar peripherals.
• Contributing to product assembly and board bring-up and validation.
• Ensuring proper packaging of PCBs for IP-related activities.
• Interacting with vendors for PCB manufacturing, SI/PI, and Assembly.
• Defining and executing verification and validation procedures.
• Supporting prototypes and manufacturing builds.
• Ensuring reliable system behavior in real-world use.
• Focusing on design, integration, evaluation, and system validation.
• Participating in building the process & tool chain.
