About the role
- We're looking for a Signal Integrity Engineer to join our hardware team and help ensure our AI-powered devices perform flawlessly at the electrical level.
- In this role, you'll own SI analysis across high-speed interfaces - DDR, PCIe, USB, MIPI - and work closely with our PCB layout, ASIC, and mechanical design teams to solve the unique challenges that come with packing serious compute into compact, thermally constrained form factors.
Responsibilities
- SI Analysis: Perform pre-layout and post-layout signal integrity simulations for high-speed interfaces (DDR4/5, PCIe Gen3/4, USB 3.x, MIPI CSI/DSI).
- PI Analysis: Model and optimize power distribution networks (PDN), including decoupling strategies, plane resonance, and target impedance.
- Channel Modeling: Build channel models for SerDes links, run eye diagram analysis, and validate compliance margins.
- Design Rules: Develop and maintain SI/PI design guidelines and constraint sets for the hardware team.
- Build channel models for SerDes links, run eye diagram analysis, and validate compliance margins.
- Develop and maintain SI/PI design guidelines and constraint sets for the hardware team.
- You'll run simulations, validate designs in the lab, and feed findings back into our design rules as we scale from prototypes to volume production.
- Hark is an artificial intelligence company building advanced, personalized intelligence.
- We're pairing that intelligence with next-generation hardware to create a universal interface between humans and machines.
- Background in RFIC or antenna design for Wi-Fi, Bluetooth, or UWB systems.
Requirements
- Tool Proficiency: Hands-on experience with SI/PI tools such as Ansys HFSS, Keysight ADS/PathWave, Cadence Sigrity, or Simbeor.
- High-Speed Interfaces: Deep working knowledge of DDR, PCIe, USB, and/or MIPI signaling standards and compliance testing.
- Hands-on experience with SI/PI tools such as Ansys HFSS, Keysight ADS/PathWave, Cadence Sigrity, or Simbeor.
- Deep working knowledge of DDR, PCIe, USB, and/or MIPI signaling standards and compliance testing.
Skills
- Expert-level skills with high-bandwidth oscilloscopes, VNAs, TDR equipment, and near-field EMI probes.
- PCB Knowledge: Strong understanding of multi-layer PCB fabrication, materials (Dk/Df), and controlled-impedance routing.
- Bonus Qualifications
- Experience with LPDDR5 or high-speed memory interfaces on mobile/edge compute platforms.
- Familiarity with 3D electromagnetic solvers for package-level or connector modeling.
- Compensation
- The US base salary range for this full-time position is between $120,000 - $300,000 annually.
- The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience.
- This information will be shared if an employment offer is extended.
