On-site
Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge.
For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles.
Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more.
We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet.
Responsibilities:
- Define the requirements of electric or chemical propulsion systems on spacecraft.
- Perform analysis and trades for electric or chemical propulsion systems.
- Define placement and integration of electric or chemical propulsion systems.
- Manage propulsion system budgets (mass, power, volume, etc).
- Work with external vendors in defining chemical propulsion flight systems and their integration on spacecraft.
- Work with external vendors or partners in the development and qualification of electric propulsion systems.
- Develop propulsion system designs and models.
- Conduct analyses and risk assessments to ensure compliance with performance, reliability, and safety requirements.
- Optimize designs for weight reduction, material selection, and manufacturability.
- Evaluate and select appropriate materials and processes for use on a spacecraft.
- Collaborate with cross-functional teams to integrate propulsion systems with other subsystems (e.g., electrical, thermal, structure).
- Participate in the assembly, integration, and testing (AIT) process of spacecraft hardware.
- Perform or manage environmental testing, such as radiation, EMI/EMC, vibration, shock, and thermal vacuum tests.
- Assess supplier capabilities and manage ongoing supplier performance to maintain quality and reliability of system components.
- Prepare technical documentation, including engineering drawings, specifications, and test reports.
- Maintain accurate records of design changes, test results, and other engineering documentation.
- Generate comprehensive reports and presentations to communicate design concepts, analysis results, and recommendations to stakeholders.
- Stay updated with the latest advancements in electric and chemical propulsion.
- Identify areas for improvement in design methodologies, manufacturing processes, and quality control.
- Contribute to research and development projects aimed at enhancing spacecraft performance and capabilities.
- Mentor junior engineers and interns, facilitating knowledge transfer and professional development within the team.
Requirements:

- Familiarity with manufacturing processes for aerospace-grade materials and components.
- Strong understanding of the qualification process of electric propulsion systems and their integration on spacecraft.
- Experience in testing electric propulsion systems. Detailed knowledge of vacuum systems, high-voltage power and fluid delivery systems for ground test, data acquisition systems, thrust stands, and plasma diagnostics, are a plus.
- Working knowledge and experience with chemical propulsion systems.
- Experience operating electric propulsion systems on spacecraft is a plus.
- Excellent problem-solving skills and the ability to work in a fast-paced, collaborative environment.
- Effective communication skills to convey complex technical information to diverse audiences.
- Attention to detail and commitment to delivering high-quality work.
- Familiarity with industry standards and regulations, such as ASME, ASTM, and NASA guidelines.
