Space Systems Engineer
Defense is migrating to space-based ISR, comms, and PNT faster than anything else in the stack. Space systems engineering is where the next decade of platforms live.
Courses for this role
Foundations
Orbital mechanics, spacecraft subsystems, radiation environments, and the rocket-equation realities that constrain every design choice.
Two-body problem, Hohmann transfers, station-keeping budget.
The functional decomposition every smallsat shares.
Vectors, frames, time systems — the unglamorous math.
Defense orbits and solar-event environments will fry commercial-off-the-shelf parts. RAD-HARD (e.g. RH-PowerPC, Vorago) vs RAD-TOLERANT (screened-COTS like Microchip / Frontgrade) vs commercial — the trade you make on every box.

Build the stack
Mission design tools, link math, MBSE modeling, and the smallsat avionics stack used by NewSpace defense companies.
The mission-analysis tools every space SE uses. STK is the gold standard in defense; GMAT is NASA's open-source equivalent.
SDA Tranche 1/2, Space RCO, and most modern defense space programs require MBSE for requirements traceability across constellations of dozens to hundreds of satellites. Document-based SE no longer scales.
OBC, ADCS, EPS — knowing the bus is the job.
The international standards every smallsat's ground link runs against — telemetry, command, file delivery.
You only have a working link if the math closes — path loss, atmospheric attenuation, ground station G/T, interference margin. Every space SE owns the budget for their mission's downlinks.
You only have data if the ground side works.

The de facto standards smallsat hardware ships against.
Field experience
Launch integration, mission operations, anomaly response, and the export-control / launch-licensing world space SEs operate in.
Fit checks, mass properties, random vibe, shock — the "does it actually survive the rocket" side of the job that catches software-heavy engineers off guard.
Pre-launch to end-of-life flight planning.
When something is wrong on orbit, the SE is the one diagnosing it.
Spectrum and remote-sensing licenses must be filed before launch.
Most space hardware is export-controlled.
