Jobs at Rainmaker Technology Corporation

Owns state and local regulatory permitting for domestic cloud seeding programs. Responsibilities include scoping requirements, preparing and shepherding permits and licenses, coordinating environmental and water-resource approvals, managing NOAA and state reporting, maintaining compliance calendars and authorization records, and advising program teams. The role also develops regulatory playbooks, builds agency relationships, supports new-state feasibility evaluations, and drives continuous improvement of regulatory submissions.

Design, prototype, machine, and test high-velocity nozzles, aerosol generators, powder feeders, and pneumatic systems for liquid and dry-powder dispersion. Develop multiphase flow hardware under aerospace size, weight, and power constraints, integrate systems into UAS payloads, characterize particle and droplet sizes, and rapidly iterate designs using experimental data and computational modeling.

Lead end-to-end procurement and sourcing for production parts, including supplier qualification, negotiations, delivery tracking, expediting, and supply chain risk management. Manage supplier relationships, procurement activity in NetSuite and Cofactr, and cross-functional coordination with engineering, production, and logistics. The role requires securing cost, capacity, and lead-time performance while bringing structure and urgency to a growing startup environment.

Conduct satellite remote-sensing research supporting cloud-seeding operations. Develop, reproduce, validate, and improve retrieval algorithms; build automated scientific data products; collocate satellite observations with radar, aircraft, UAS, soundings, surface data, and numerical weather prediction; quantify uncertainty and failure modes; support real-time cloud analysis; and transition reliable workflows into operational systems.

Build and improve data workflows for in-situ, remote, and drone telemetry; support APIs, packages, and operational tools; and transform raw data into reliable internal products. The role requires strong Python skills, comfort with data, APIs, and SQL, debugging ability, and interest in geospatial, atmospheric, or sensor data. Relocation to El Segundo, California is required.

Support accounting operations across accounts payable and accounts receivable, including invoice processing, vendor and customer records, reconciliations, cash application, aging reviews, discrepancy resolution, month-end close, reporting, and internal controls. The role partners with cross-functional teams to improve workflows, maintain accurate financial data, and provide accounting project support.

Design and prototype electrical subsystems for unmanned aerial systems, including PCB schematics and layouts, power distribution, sensor interfaces, payload controllers, and communications modules. Assemble and debug boards, develop testing procedures and fixtures, document designs, and collaborate with mechanical, software, and manufacturing teams. The role supports mission-critical UAS subsystems and incorporates flight-test feedback into rapid hardware iterations.

Lead electrical system architecture and hardware design for UAS, sensing, and payload platforms. Design and prototype PCBs, perform board bring-up and testing, develop documentation, and guide systems through manufacturing. Work with embedded platforms, microcontrollers, high-speed digital systems, power and signal integrity, EMI/EMC, and low-level embedded programming. Mentor engineers and collaborate with mechanical, software, research, and manufacturing teams.

Develop quantitative methods to identify and evaluate cloud-seeding opportunities, analyze meteorological data, design causal and statistical studies, improve forecasting and nowcasting workflows, and establish validation and uncertainty frameworks. Build reproducible decision-support tools using weather observations, numerical models, radar, satellite, and machine learning. Collaborate with scientists, engineers, operators, customers, regulators, and commercial teams to support program design, operational decisions, and performance evaluation.

Develop and extend PX4 firmware and drone autonomy software for autonomous fleets. Build embedded firmware for power, peripheral, and sensing systems; support Gazebo, HITL, and SITL simulation testing; assist with flight tests, log analysis, and debugging. The role requires production Rust development alongside C++ or Python, embedded experience, low-level peripheral buses, real-time pub/sub middleware, and MAVLink autopilot integration knowledge.

Leads business development for California state government customers, owning revenue targets and pipelines tied to appropriations, grants, contracts, and pilot programs. Builds relationships with legislators, agencies, water districts, and industry partners; shapes legislative and budget policies; develops public/private partnerships; supports proposals and procurement compliance; organizes demonstrations and stakeholder events; and reports market intelligence, pipeline forecasts, and strategic recommendations.

Support company planning and strategic initiatives by tracking priorities, budgets, headcount, milestones, and capacity. Coordinate cross-functional work across engineering, science, production, field operations, commercial, finance, and people teams. Develop operational processes, workflows, reporting systems, and decision-ready leadership analysis. Support business reviews and planning cycles while owning high-priority special projects.

Establish Rainmaker’s machine learning strategy and deliver operationally useful models for atmospheric science and cloud-seeding operations. Responsibilities include prioritizing ML opportunities, building forecasting and multimodal models, combining radar, satellite, UAS, and in-situ data, creating datasets and evaluation procedures, assessing uncertainty and failure modes, and collaborating with atmospheric scientists and software engineers to productionize successful research.

Own Rainmaker’s production infrastructure and security, including cloud systems, deployments, CI/CD, observability, identity and access, secrets, vulnerability management, incident response, and recovery. Build reliable 24/7 remote systems that tolerate lost communications, establish deployment and recovery standards, and support rapid software development across engineering, science, aircraft, and field operations.

Own development of airborne atmospheric sensing hardware from scientific requirements through architecture, design, fabrication, calibration, flight testing, validation, and production. Lead delivery of a cloud-particle imaging instrument for UAS deployment, coordinate multidisciplinary engineering and science teams, resolve integration issues, establish verification and acceptance procedures, and develop the company’s atmospheric-instrumentation roadmap.

Build and maintain full-stack software across internal tools, campaign planning, field operations, weather and geospatial data, aircraft operations, and customer-facing products. Work directly with users and cross-functional teams to identify problems, prototype solutions, and own products through deployment and continued development. Improve shared software components and technical patterns across the organization.

Supports mechanical engineering for UAS mission-critical subsystems through rapid hardware prototyping, test fixture design, FEA studies, technical documentation, and fabrication data preparation. Collaborates with electrical, software, manufacturing, and mechanical engineering teams. Uses SolidWorks, FEA, 3D printing, and prototyping methods to iterate designs based on flight-test feedback and mission requirements.
