Principal Ionospheric Physicist

Principal Ionosospheric Physicist

?Remote (U.S.) ? $150k–$200k Base + Significant Equity

We're partnering with an innovative early-stage technology company developing next-generation environmental intelligence software for national security and commercial space applications. They are seeking a Principal Ionospheric Physicist to lead the scientific development of a real-time ionospheric modeling and data assimilation platform, transforming cutting-edge research into operational capability.

This is a rare opportunity to join a founding-level team where you'll own the scientific direction of a flagship product, working directly alongside senior technical leadership to solve some of the most challenging problems in space weather, atmospheric physics, and real-time environmental intelligence.

What You'll Be Doing

• Lead the development of real-time ionospheric reconstruction algorithms using tomographic and sequential data assimilation techniques.
• Advance physics-based models that fuse multiple live data sources into accurate volumetric electron-density estimates.
• Develop methods to distinguish natural ionospheric effects from system anomalies, interference, jamming, or other operational impacts.
• Work closely with software engineers to transition research algorithms into scalable production software.
• Define validation strategies, performance metrics, and scientific benchmarks for operational deployment.
• Collaborate with customers and technical stakeholders to translate scientific capability into mission-focused solutions.
• Produce technical reports, whitepapers, and presentations supporting customer engagements and product development.

What We're Looking For

• Strong background in ionospheric physics, space physics, atmospheric physics, geophysics, or a closely related field.
• Experience developing real-time tomographic reconstruction or volumetric electron-density estimation methods.
• Expertise with Kalman filtering, sequential estimation, ensemble methods, or other data assimilation techniques.
• Experience integrating heterogeneous observational datasets such as GNSS, radio occultation, ionosondes, radar, in-situ sensors, or similar.
• Strong scientific computing skills (Python or similar numerical environments).
• Ability to communicate complex technical concepts clearly to both engineering teams and technical customers.
• Proven ability to take scientific research through to operational or mission-ready implementation.

Nice to Have

• PhD in a relevant scientific discipline.
• Experience with RF propagation, GNSS, SATCOM, radar, or space weather impacts on communications and navigation.
• Background in attribution analytics, anomaly detection, or environmental intelligence.
• Experience deploying scientific or ML-driven products into operational environments.
• Active U.S. Security Clearance or ability to obtain one.

Why Join?

• Founding-level opportunity with significant technical ownership.
• Meaningful equity alongside a competitive salary.
• Direct influence over a flagship technology from research through operational deployment.
• Small, highly technical team with rapid decision-making and direct customer engagement.
• Opportunity to work on problems at the intersection of AI, space weather, atmospheric science, and national security.

Please note: U.S. Citizenship is required due to the nature of the work. Periodic travel to customer and partner sites may be required.
