Embedded HW/SW Engineer

C onfigure long range RF (e.g., subGHz ISM, LoRa/LoRaWAN, FSK/OOK, possibly QAM) and integrate satellite modems (e.g., Iridium/Globalstar); design robust telemetry with retries, compression, and over the air update pipelines.

Deploy onboard processing for filtering, feature extraction, and basic anomaly detection; optimize for low power duty cycles.

Engineer for environmental extremes (humidity, salt fog, thermal cycling); contribute to enclosure/IP sealing choices.

Author test plans, fixtures, and scripts; run HAL/driver unit tests, RF link tests, and environmental performance tests.

Drive DFM/DFT decisions and supplier selection; support pilot builds and yield/debug during production ramp.

Support field deployments and remote troubleshooting; collaborate closely with modeling/forecasting and decision software teams to ensure sensor outputs meet platform needs.

Maintain schematics, BOMs, ICDs, and test reports; contribute to platform standards and best practices across future vehicle types.

Mesh protocols: LoRaWAN, Thread, Zigbee, 6LoWPAN, or custom routing over subGHz.

OTA update frameworks, secure boot, encryption, and key management for edge devices.

Low power design (sleep states, power gating), energy harvesting, or field hardening for harsh environments.

Experience in new space or aerospace hardware programs (e.g., launch/on orbit/avionics environments with rapid iteration and strong reliability culture).

Basic edge ML or DSP for feature extraction; telemetry compression.

Working with contract manufacturers, suppliers, and reliability testing standards (HALT/HASS, environmental).

30 days: Deliver a subsystem plan and component selections; bring up dev boards and a set of sensors

60 days: Demonstrate a single mesh node prototype with RF + satellite backhaul and reliable logging; baseline power profile.

90 days: Expand to multiple mesh elements, exercising the full stack, and prepare for a productionized variant

Weather shapes every decision made on Earth. At Mantari you’ll write code that moves metal, launch sensors that tame storms, and see your work ship in weeks—not years. Join us to build the world’s first private full-stack weather platform and leave your fingerprints on infrastructure that will outlast us all. Apply now—let’s create the future of weather, together.
