Jobs at Rain

Own state and local permitting for domestic cloud seeding programs: scope regulatory requirements, draft and shepherd permits and licenses, manage environmental approvals, maintain compliance reporting (NOAA Form 17-4), and build state-by-state playbooks and stakeholder relationships to ensure authorized, on-time operations.

Support company planning and translate growth plans into operational requirements. Drive cross-functional strategic initiatives, build processes and reporting, produce decision-ready analysis for leadership, support planning and reviews, and own high-priority special projects.

Plan and execute public-facing events and sponsorships to build grassroots awareness. Manage end-to-end logistics, vendor and press relationships, run-of-show, creative activation ideas, and post-event follow-up. Work with Brand and Public Affairs, capture event content, and engage audiences to translate complex technical ideas into accessible stories.

Develop and validate satellite retrievals and automated workflows for cloud, precipitation, and atmospheric state. Collocate and evaluate satellite products with radar, aircraft, NWP, and in-situ data; quantify uncertainty and operationalize data products to support cloud-seeding operations and real-time analysis.

Build quantitative methods and tools to identify, rank, and evaluate cloud-seeding opportunities; analyze historical and real-time meteorological data; design experiments and uncertainty bounds; automate forecasting/nowcasting workflows; develop decision-support combining NWP, radar, satellite, in-situ observations; translate meteorological knowledge for ML and operational systems; communicate results to cross-functional stakeholders.

Lead ML research to prioritize and deliver operational models using multimodal atmospheric, radar, satellite, and in‑cloud data. Build datasets, baselines, uncertainty-aware evaluations, and prototypes that meteorologists and engineers can productionize. Work directly with domain scientists, run experiments, and turn results into operational improvements for cloud‑seeding and related forecasting tasks.

Lead technical development of airborne atmospheric sensing instruments from requirements through design, fabrication, calibration, flight testing, validation, and production transition. Integrate optics, mechanics, electronics, embedded control, and data systems; coordinate cross-functional and vendor work; design verification and calibration plans; and establish instrumentation roadmap and field-support procedures.

Own and build customer-facing geospatial and data-visualization products: interactive campaign visualizations, GIS proposal tooling, demo environments, component library, and instrumentation to drive sales and customer trust. Full-stack ownership from frontend (React/TypeScript) to backend (Python/Node), architecture, and product design.

Design, prototype, and test high-velocity nozzle and multiphase dispersion systems for aerosols and dry powders; develop pneumatic/fluidic architectures, integrate lightweight UAS payloads, iterate based on droplet/particle size data, and perform hands-on machining and fabrication under aerospace SWaP constraints.

Develop and extend PX4 firmware and embedded systems for drone autonomy. Implement custom flight behaviors, support simulation (Gazebo, HITL, SITL), perform flight test support, log analysis, and debugging across sensing, power, and peripherals.

Lead end-to-end recruiting: build scalable sourcing, structured interviews, calibrated debriefs, and closing playbooks; own candidate experience and uphold hiring standards across technical, scientific, and operational roles.

Support AR and AP functions including invoice entry, vendor/customer account maintenance, cash application, reconciliations, month-end close support, reporting, and discrepancy resolution. Partner with cross-functional teams, improve workflows, and provide ad hoc support to the Accounting Manager.

Lead business development with California state government for Rainmaker's water and precipitation programs. Own revenue targets, build pipelines across appropriations, grants, and contracts, cultivate legislative and agency relationships, shape policy and budget engagement, coordinate public/private partnerships, support cross-functional pursuits, and run events and market intelligence to secure funded work.

Lead architecture, PCB design, and rapid prototyping of electrical systems for UAS and payloads. Perform board bring-up, testing, documentation, and cross-functional integration. Mentor engineers and drive designs from concept through manufacturing and flight validation.

Design and analyze aerodynamic configurations for UAS operating in extreme weather using CFD (Ansys preferred), CAD (SolidWorks preferred), wind‑tunnel testing, and composite manufacturing; collaborate with multidisciplinary teams to translate designs into manufacturable prototypes and validate performance.

Build and improve data workflows for in-situ, remote, and drone telemetry; support APIs, packages, and operational tools; transform raw data into reliable internal products. Work with Python, SQL, and debugging across systems. Position requires relocation to El Segundo, California.

Lead state-focused business development in Nevada for precipitation enhancement and water resource programs. Own revenue targets, identify funding pathways (appropriations, grants, contracts), build legislative and agency relationships, shape policy, coordinate public/private partnerships, support proposals with cross-functional teams, organize demonstrations and events, and track market intelligence to convert opportunities into funded programs.

Lead end-to-end procurement for production parts, source and qualify domestic suppliers, negotiate strategic agreements, manage procurement in NetSuite/Cofactr, coordinate logistics for expedited delivery, and partner with engineering and production to mitigate supply chain risk.
