- Familiarity with multiple sales models and sales qualification methodologies (BANT, MEDDIC, etc.), ideally in an aerospace or B2B SaaS setting.
- Strong understanding of social media best practices and platform-specific audience engagement.
- Unrestricted social media accounts (or ability to generate and grow them) for use in business development efforts.
- Sufficient technical aptitude to understand and convey the basics of OpenC3 COSMOS to target audiences and personas.
- Strong work ethic and ability to remotely work independently and as part of a team.
- A proactive mentality that doesn't wait for inbound leads, with a proven track record of inserting yourself into the right conversations and opening doors that others find locked.
