Who Are We?

At HyPrix, we're building attritable payload delivery systems for autonomy. Things that fly quick, we're enabling them with conscious software. Replicating the capabilities of expensive conventional frontline systems, we're building the cheapest micro and cruise missile systems on the planet. Built for a war of attrition, built for the era of software-defined warfare, built to cater to the front lines of battlefields where no man should stand in the future.

What You'll Do

The SI/PI Engineer makes sure that the high-speed interfaces and power delivery networks on HyPrix avionics boards meet their signal quality, timing and noise margins. The position holder runs the simulations, reviews schematics and layouts, and advises the hardware and PCB layout teams on design fixes.

The boards use Ethernet (1G and 2.5G), DDR4, LPDDR4 and eMMC interfaces, and must operate in harsh avionics environments.

• Pre-layout analysis. After schematic release and before layout, simulate each critical interface with IBIS models: topology, termination,



drive strength and timing. Define the layout constraints: impedance, length and skew, spacing, via and reference plane rules.

• Schematic reviews. Review schematics for SI and PI: terminations, AC coupling, decoupling and power rail filters.

• Stack-up. Define and check the stack-up and impedance targets with the PCB layout team and the fabricator.

• Post-layout simulation. Extract each routed board in Ansys SIwave and Ansys Electronics Desktop (EDT). Simulate reflections, crosstalk, insertion and return loss, eye diagrams and BER.

• Memory interfaces. Analyse DDR4, LPDDR4 and eMMC signal quality and timing margins, with the on-die termination and drive strength settings.

• Power integrity. Simulate PDN impedance against the target impedance, and calculate the decoupling capacitor values, quantities and positions. Check DC IR drop on the critical power rails.

• Layout reviews. Revi
