Job Description
Spacecraft ADCS Engineer Design the Attitude Control Systems Powering the Next Leap in Orbital Infrastructure!
Jacksonville, FL | Onsite
Opportunity Summary
A well-funded seed-stage startup is building the next generation of orbital systems to power a persistent in-space energy network. At the center of this initiative is a spacecraft platform designed to beam power wirelessly between satellites, unlocking a new era of autonomy and capability for commercial and government missions. We're seeking a hands-on engineer with a strong background in spacecraft Attitude Determination and Control Systems (ADCS) to help architect, model, and implement the full ADCS stack. You'll own the development of key flight software, guide hardware selection, and play a critical role in testing and verification of the vehicles navigation and pointing capabilities.
About Us
Were a Jacksonville-based space company on a mission to build infrastructure that enables the in-space economy. Our founding team brings deep technical leadership from successful aerospace ventures and government programs. With early funding secured and aggressive timelines ahead, were growing our core engineering team to deliver the first nodes of an orbital energy network, starting with a small, smart spacecraft designed for near-term flight.
Job Duties
- Own the design and integration of the ADCS subsystem across hardware, software, and test
- Develop real-time embedded algorithms for guidance, navigation, and control
- Define requirements for control systems and guide hardware downselection and procurement
- Simulate spacecraft dynamics using MATLAB, Python, or similar tools
- Support creation of hardware-in-the-loop (HIL) testbeds for ADCS performance evaluation
- Collaborate across mechanical, systems, and software teams to ensure successful integration
- Lead development of the ADCS verification and validation campaign, including environmental and acceptance-level testing
- Ensure subsystem documentation is complete, clear, and traceable
- Track progress against technical goals, timelines, and deliverables
Qualifications
- Bachelors degree in Aerospace Engineering, Mechanical Engineering, Computer Engineering, or a closely related field
- 3+ years of experience working on spacecraft or aerospace control systems
- Proficient in C/C++ for embedded development
- Strong understanding of control theory, including nonlinear and optimal methods
- Familiarity with modeling and simulation tools such as Python, MATLAB/Simulink, or similar
- Demonstrated experience with spacecraft ADCS or GNC systems design and implementation
- Effective communicator with ability to work across technical disciplines
Preferred Experience
- Expertise in spacecraft ADCS tuning, sensor fusion, or advanced estimation methods
- Experience operating or supporting flight systems in a mission environment
- Familiarity with space vehicle testing environments (thermal, vacuum, vibration, etc.)
- Knowledge of relevant spaceflight regulations and standards (safety, reliability, compliance)
- Hands-on experience with building custom test benches or hardware emulation setups
- Background in small satellite programs or fast-paced R&D environments
Why Join Us
- Build a space system from the ground up alongside highly experienced founders
- Contribute to foundational infrastructure for the future in-space economy
- Clear path to ownership over technical direction and long-term architecture
- Flexible, collaborative work environment with room to innovate
- Competitive salary and early equity in a high-growth startup
- Strong health benefits: medical, dental & vision
- Generous PTO and paid holidays
- 401(k) with matching options
