Make Snow. Make Earth Habitable.\nRainmaker 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.\nOur ambition is bold, but we pursue it with humility. We take on difficult problems in the real world with technical rigor, grit, integrity, and an openness to learning and course-correcting. We are hiring individuals with evidence of exceptional ability. If you want to build systems that endure, restore, and deliver the future we were promised, we want to hear from you.\nThe vehicle software team builds the software that operates Rainmaker’s cloud-seeding vehicles, connecting flight control, onboard computing, sensors, payloads, and ground operations. We work closely with electrical, mechanical, manufacturing, and flight operations teams to turn new hardware into reliable systems that can be built, deployed, and operated at scale. Our goal is to make every vehicle a dependable tool for delivering more freshwater where it is needed.\nAbout the Role\nYou will own embedded firmware across Rainmaker’s vehicle and its integration with our onboard and ground control software systems. Your scope includes flight-controller firmware, power distribution, sensor and payload controllers, and the interfaces connecting those systems to onboard Linux software. You will take work from architecture and board bring-up through testing, manufacturing, deployment, and support in the field. We’re looking for a high-agency engineer who identifies what needs to happen, turns incomplete requirements into a clear plan, and follows through until the hardware works reliably in real operating conditions. This is a hands-on technical ownership role with the autonomy to shape the firmware architecture and the responsibility to deliver it.\n\nWhat You'll Do\n\nOwn the architecture, implementation, and maintenance of all embedded firmware across the vehicle, including flight-controller firmware, power distribution, sensors, and seeding payloads.\n\nSet firmware priorities, identify reliability risks and technical gaps, and drive projects from an ambiguous problem to a validated release.\n\nBring up new boards with electrical engineers: read schematics, validate interfaces, write drivers, and debug failures at the boundary between hardware and software.\n\nDevelop dependable device communication and command handling over CAN, UART, SPI, and I2C, with clear contracts for telemetry, timing, and fault behavior.\n\nIntegrate firmware with our vehicle software so commands, device state, and telemetry behave consistently from the microcontroller to the operator.\n\nDesign and validate safe startup states, watchdogs, interlocks, and recovery behavior for resets, communication loss, sensor faults, and interrupted updates.\n\nOwn firmware builds, versioning, flashing, over-the-air updates, and recovery workflows so deployed vehicles run known, traceable software.\n\nBuild automated tests, simulation, and hardware-in-the-loop coverage that catch regressions and exercise failure modes before releases reach the fleet.\n\nPartner with manufacturing and flight operations to make provisioning, calibration, diagnostics, and servicing repeatable and practical.\n\nInvestigate bench and field failures using logs, telemetry, and lab instruments; resolve root causes and turn what you learn into better software and tests.\n\nWhat We're Looking For\n\n3+ years of hands-on experience developing embedded software or firmware for microcontroller-based systems, including board bring-up, hardware integration, and deployment into production or field use.\n\nDemonstrated ownership of an embedded subsystem from design through release and ongoing support, including making technical decisions independently, validating behavior on hardware, and resolving failures in real operating conditions.\n\nStrong systems programming skills in Rust and/or C/C++, with the ability and willingness to work across both Rust and C/C++ codebases.\n\nPractical experience with peripheral drivers and communication buses such as CAN, UART, SPI, and I2C.\n\nComfort reading schematics and using oscilloscopes, logic analyzers, and hardware debuggers to isolate problems across electrical and software boundaries.\n\nThe ability to reason about system failures and implement robust state machines, fault detection, safe outputs, and recovery paths.\n\nExperience building maintainable firmware with version control, reproducible builds, automated testing, and disciplined release practices.\n\nEvidence of high agency: you surface problems without waiting to be assigned, make sound decisions with incomplete information, ask for help when it matters, and close the loop on results.\n\nClear communication and the ability to work closely with hardware engineers and operators, explain tradeoffs, and document decisions so others can build and service what you ship.\n\nWhat Will Set You Apart\n\nExperience with drones, robotics, aerospace, or other systems where software controls physical equipment in demanding conditions.\n\nFamiliarity with PX4, MAVLink, flight-controller development, or flight-critical software.\n\nWhat Success Looks Like In the First 90 Days\nYou 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.\n\nSupporting the Rainmakers behind the mission\nMaking earth more habitable is ambitious work and we want the people doing it to feel supported:\nA stake in what we build: Meaningful stock options and the opportunity to help shape Rainmaker as an early member of the team.\n\nSupport for your health: Comprehensive medical, dental, and vision insurance for you and your family.\n\nAn investment in your future: A 401(k) with employer matching to help you build long-term savings.\n\nTime to recharge: Unlimited PTO for rest, exploration, and the people and pursuits that matter to you plus a generous paid holiday schedule.\n\nTime for a growing family: Paid parental leave for both parents to welcome a child and spend time together.\n\nLunch together: Daily lunch provided at our El Segundo headquarters, giving Rainmakers a chance to share a meal and connect with teammates.\n\nHelp making the move: Relocation assistance for eligible roles to support your transition to Rainmaker.\n\nRainmaker Is An Equal Opportunity Employer\nEmployment decisions are made without regard to any characteristic protected by applicable federal, state or local law.\nRainmaker provides reasonable accommodations to qualified individuals with disabilities and for other protected reasons as required by law.
