Weekend Repo Jobs in California (NOW HIRING)

If you see gaps where others see limits, keep reading.

Mantari is taking a moon-shot swing at modernizing global weather intelligence-owning the full stack from novel sensors to AI-native forecasts to decision products that move markets and militaries. We've raised pre-seed capital and we're scaling fast. But some of the best people don't fit clean job boxes-so we built one just for you.

• Find the biggest lever inside our sensing data model product pipeline and pull it hard-whether that's writing CUDA kernels for a new GPU ensemble, designing a buoy powertrain that survives the Bering Sea, or brokering a data-sharing deal with Space Force.

• Ship early and often. Prototype in weeks, not quarters. Own the win-conditions and the post-mortem.

• Operate founder-level. Challenge strategy, shape roadmaps, and hire/mentor talent as we grow.

• Stretch beyond your lane. If your idea can 10 forecasting (or decision-making) skill, you'll get the runway to prove it.

• An ML engineer who rips apart climate models on JAX-but also tunes RF front-ends on the weekend.

• A systems hacker who's built satellites, sensor nets, or HF comms and wants to aim that skill at weather.

• A go-to-market savage who's closed eight-figure gov-tech deals and can decode FAR acronyms in your sleep.

• A product polymath who turns messy data into dashboards that pilots, traders, and warfighters swear by.

If none of these sound like you, perfect. Prove we missed a category.

• Extreme ownership. You default to "I'll figure it out" across hardware, software, or BD.

• Rate of learning that makes diplomas look slow. You teach us something in the first interview.

• Bias for action in chaotic, zero-hand-holding environments.

• Signal of excellence in any domain: patents, open-source projects, combat deployments, PhD papers, startup exits-show us your spike.

• You've delivered at least one production system or deal that moves Mantari's core metrics (forecast skill, sensor coverage, ARR, or strategic leverage) by an order of magnitude.

• Your work is cited in investor decks and DoD briefings as a reason Mantari wins.

• Mission, not maintenance. We're replacing government-era infrastructure with a private, AI-native platform that restores U.S. dominance in weather intelligence.

• Vertical playground. Sensors, edge compute, deep-learning models, dual-use applications: the whole stack is on the table.

• Talent density. Work alongside ex-SpaceX engineers, former NCAR fellows, and business magicians who care about impact over ego.

• Upside. Competitive cash, meaningful equity, and the chance to write your own role into the org chart.

Send us one artifact that proves you're the outlier we need-code repo, white paper, deal sheet, hardware teardown thread, battlefield story-plus a resume or LinkedIn. Drop it at careers@mantari.com with a two-sentence pitch on why us, why now.

Weather decides wars, markets, and human safety. If you're ready to bend that curve, let's talk.
