- Basic understanding of data analysis and visualization techniques.

- Strong problem-solving skills with a keen attention to detail.

- Excellent communication skills, with the ability to explain technical concepts to diverse audiences.

- Passion for aerospace, autonomous systems, or advanced engineering applications.

- Eagerness to learn and adapt in a fast-paced startup environment.

- Bachelor’s degree in computer science, data science, engineering, math, physics, or a STEM discipline.

BONUS POINTS

- Experience in any of the following: - Aerospace systems, satellite operations, or autonomous vehicle development. - Data streaming technologies or time-series databases (e.g., Kafka, InfluxDB). - SQL and database concepts. - Cloud platforms (e.g., AWS, GCP, Azure). - Software integration challenges in complex systems. - Machine learning or AI applications in engineering.

- Demonstrated ability to quickly learn and apply new technologies.

WHAT WE’RE LOOKING FOR

- Someone with a customer-first mindset who’s excited to solve real-world engineering problems in the field.

- An engineer who thrives in ambiguity and can adapt quickly to evolving customer needs.

- A collaborative team player who can work effectively with customers, engineers, and go-to-market teams to drive impact.

LOCATION & TRAVEL

- This role is located in San Francisco, CA. We collaborate in person four times a week—Monday through Thursday—and come together for a full week every quarter at our HQ in LA. We are open to relocating candidates to LA or our San Francisco office.
