    ABOUT SPHINX
    Sphinx builds software to solve complex national security problems in Space. Founded by engineers and technologists with deep experience across commercial and defense technology, we were frustrated by the outdated and insecure technology America's service members are forced to rely on. We're here to do better.
    We're focused on building modern, scalable products with an emphasis on using open source technologies. Expect talented, motivated, and interesting colleagues who emphasize collaboration, transparency, and individual responsibility.

    • Support capture and bid/no-bid decision making by analyzing solicitation requirements, customer needs, competitive landscape, and mission fit
    • Translate complex software, aerospace, and mission capabilities into persuasive, customer-focused proposal narratives and value propositions
    • Design and manage proposal response structures, schedules, workflows, and responsibilities to meet submission deadlines while maintaining high quality and accuracy
    • Ensure all proposal responses adhere to solicitation requirements, internal standards, and proposal best practices
    • Contribute to win strategies, solution positioning, and competitive analysis in support of mission-critical opportunities
    • Build and scale repeatable proposal and capture processes to support business growth in the defense sector
    You might be a good fit if you:
    • Have5+years of experience managing proposals in the defense, space, or government contracting environment
    • Have hands-on experience researching, evaluating, and responding to DoD RFPs, RFIs, and SBIR solicitations
    • Possess strong knowledge of the DoD acquisition process, contract types, and proposal lifecycle
    • Bring experience supporting business development and early-stage growth, particularly within small or emerging defense companies
    • Have direct experience working within the aerospace, defense, intelligence, or space industry
    • Demonstrate familiarity with command and control (C2) systems, mission operations systems, and associated software and infrastructure
    • Are able to coordinate cross-functional teams under tight deadlines in high stakes environments
    • Exhibit exceptional written and verbal communication skills, translating complex technical concepts into clear, compelling narratives
    • Show strong attention to detail, organization, and problem-solving skills in fast-paced environments
