Sponsors, but it's cap-subject — you still face the weighted lottery (~45% per draw at Level III). Good if you win; have a cap-exempt backup on your list.
Lottery odds assume a STEM candidate.
Personalize to your clock →H-1B wage level
the lottery is wage-weighted — each level is one more entry
$5,305 more — $117,645 — moves this role to Level II and 2 lottery entries. That figure is inside the range the employer already advertised.
Based on the DOL prevailing wage for this occupation and worksite, a base salary of $117,645 would place this position at wage Level II. That figure is within the posted range, and I'd like to target it. This role classifies under "Electrical Engineers" for prevailing-wage purposes.

About the role
- Next, Haven-1 is expected to become the world's first commercial space station when it launches in 2027, followed by additional Haven modules.
- Additionally, the company recently announced Vast Satellite, a high-power satellite product line leveraging its space station components and the heritage of Haven Demo.
- This will be a full-time, exempt position located in our Long Beach location.
Responsibilities
- Own the satellite power system end to end, including architectural trades, functional and technical interface definitions (hardware and software), hierarchical requirements specification, and verification and validation planning and execution
- Serve as the technical authority for the spacecraft power system. Own flight readiness assessment, disposition nonconformances and waivers against the power system, and hold final sign-off authority on power system configuration for launch
- Define ground and flight power modes and own the power budget.
- Build and defend first-principles energy balance models that size generation, storage, and margin across orbit geometries, eclipse profiles, and off-nominal modes to verify power positivity, and justify the model fidelity chosen for the decision being made
- Drive power-relevant design decisions across mechanical, thermal, propulsion, GNC, and flight software. Capture system-level operating modes, constraints, and behaviors and drive their implementation on the power system
- surface the questions others aren't asking, escalate unresolved interface conflicts, and secure convergence on the correct integrated design
- Partner with Responsible Engineers on component-level design and test approach, ensuring component specifications and acceptance criteria trace to system-level power requirements
- Perform system-level failure modes, effects, and criticality analyses to motivate reliability design and validation plans, and architect the resulting vehicle modes, autonomous behaviors, and fault responses
- Keep Power Systems designs consistent with modular platform engineering principles across programs. Maintain system designs, processes, and validation techniques, and feed recurring issues back into design to improve reliability and streamline production
- Own all aspects of documentation for the satellite power systems, ensuring that all trade decisions and ensuing technical specifications are fully documented
Requirements
- Bachelor's degree in electrical engineering, or other engineering discipline
- Experience designing spacecraft power systems from initial requirements
- Experience with high voltage power systems above 100 V
- Experience with lifecycle development as it relates to space systems, including requirement definition, identifying design solutions, integration, validation and verification, qualification, and operation
- Experience with spacecraft power hardware, including lithium-ion battery systems, solar arrays and solar array drive assemblies, peak power tracking and regulation, and power distribution units
- Proficiency building energy balance and power budget models in Python, MATLAB/Simulink, or equivalent, including orbital illumination and eclipse analysis
- Experience designing electronics for the spaceflight environment and verifying workmanship and operability through environmental test, including random vibration, shock, thermal, burn-in, and TVAC
