Embedded Software Engineer

Rainmaker Technology Corporation, El Segundo, CA

The role

Make it rain. Make Snow. Make Earth Habitable.

Rainmaker builds and deploys audacious technologies that work with nature to create an abundant, habitable planet. We are modernizing proven cloud-seeding science with weather-resistant UAS, radar and satellite observations, numerical weather prediction, novel sensing and validation systems, and sustainable seeding technologies. We are building an integrated system to make more freshwater available to farms, ecosystems, and communities.

What you will do

What You'll Do

- Own the architecture, implementation, and maintenance of all embedded firmware across the vehicle, including flight-controller firmware, power distribution, sensors, and seeding payloads.
Set firmware priorities, identify reliability risks and technical gaps, and drive projects from an ambiguous problem to a validated release.
Bring up new boards with electrical engineers: read schematics, validate interfaces, write drivers, and debug failures at the boundary between hardware and software.
Develop dependable device communication and command handling over CAN, UART, SPI, and I2C, with clear contracts for telemetry, timing, and fault behavior.
Integrate firmware with our vehicle software so commands, device state, and telemetry behave consistently from the microcontroller to the operator.
Design and validate safe startup states, watchdogs, interlocks, and recovery behavior for resets, communication loss, sensor faults, and interrupted updates.
Own firmware builds, versioning, flashing, over-the-air updates, and recovery workflows so deployed vehicles run known, traceable software.
Build automated tests, simulation, and hardware-in-the-loop coverage that catch regressions and exercise failure modes before releases reach the fleet.
Partner with manufacturing and flight operations to make provisioning, calibration, diagnostics, and servicing repeatable and practical.
Investigate bench and field failures using logs, telemetry, and lab instruments; resolve root causes and turn what you learn into better software and tests.

What Success Looks Like In the First 90 Days

You have mapped the vehicle’s firmware, hardware interfaces, build and update paths, and most consequential reliability risks, and the team has a clear plan for what to address first. You can independently build, flash, instrument, and debug the key embedded systems and trace their behavior through our vehicle software. You have delivered a meaningful firmware improvement through bench and integration testing into an operational release, working with flight operations to verify its behavior in the field. You have improved at least one recurring source of friction in testing, provisioning, updates, or diagnostics, and established a practical ownership and release cadence for the firmware stack.

Supporting the Rainmakers behind the mission

Making earth more habitable is ambitious work and we want the people doing it to feel supported:

A stake in what we build: Meaningful stock options and the opportunity to help shape Rainmaker as an early member of the team.
Support for your health: Comprehensive medical, dental, and vision insurance for you and your family.
An investment in your future: A 401(k) with employer matching to help you build long-term savings.
Time to recharge: Unlimited PTO for rest, exploration, and the people and pursuits that matter to you plus a generous paid holiday schedule.
Time for a growing family: Paid parental leave for both parents to welcome a child and spend time together.
Lunch together: Daily lunch provided at our El Segundo headquarters, giving Rainmakers a chance to share a meal and connect with teammates.
Help making the move: Relocation assistance for eligible roles to support your transition to Rainmaker.
