Lead Software Engineer - Gov Platforms

WindBorne Systems is supercharging weather forecasts with a unique proprietary data source: a global constellation of next-generation smart weather balloons targeting the most critical atmospheric data. We design, manufacture, and operate our own balloons, using the data they collect to generate otherwise unattainable weather intelligence. Our mission is to eliminate weather uncertainty, and in the process help humanity adapt to climate change, be that predicting hurricanes or speeding the adoption of renewables. We are building a future in which the planet is instrumented by thousands of our microballoons, eliminating gaps in our understanding of the planet and giving people and businesses the information they need to make critical decisions. The founding team of Stanford engineers was named Forbes 2019 30 under 30 and is backed by top-tier investors, including Khosla Ventures and Footwork VC. We're hiring a Senior Software Engineer to own government implementations across multiple WindBorne software platforms. You'll be the technical bridge between our core technology and government customers, ensuring our systems meet rigorous compliance standards while delivering exceptional value. This role requires equal parts technical depth, attention to regulatory detail, and customer communication skills. We’re looking for someone who has built software under the weight of real compliance requirements—FedRAMP, ITAR, NIST 800-53, or equivalent frameworks that don't forgive shortcuts. This person treats compliance as an architectural constraint, not a checkbox exercise, and knows how to design systems that are both secure and performant. Auditable doesn't mean slow in their world. If you thrive in the tension between competing demands, like performance vs. security, speed vs. compliance, and flexibility vs. standardization, we want to hear from you. If you make pragmatic trade-offs, ship solutions that work, and know when a problem needs more hands or a different approach, we want to hear from you. If ambiguity doesn't slow you down, but is the environment where you do your best work, we want to hear from you! RESPONSIBILITIES In this role, you'll architect and implement government-specific versions of our software platforms, ensuring they meet security, compliance, and operational requirements unique to federal customers. This means adapting our data pipelines, APIs, and analysis tools to work within government infrastructure constraints while maintaining performance and reliability. You'll own the entire development lifecycle, working directly with government stakeholders to understand their technical requirements, troubleshooting complex integration issues, and delivering solutions that meet their mission-critical needs.
