Why pre-screen small satellite engineers before the technical loop
Small satellite programmes accept risk deliberately: commercial parts instead of qualified ones, shorter test campaigns, less redundancy. That makes the engineering judgement about which risks to take and which to buy out, and the answers are visible on orbit. Engineers worth hiring have flown hardware and can tell you what failed and whether they had predicted it. A short screen asks that directly, because designs alone do not produce it.
What actually matters when screening Small Satellite Engineer candidates
- 01
Technical depth
Probe depth on CubeSat subsystems: ADCS algorithms, EPS power budgets, S-band or UHF link budgets, radiation-tolerant COTS selection, and CAD or STK and GMAT modelling they personally built.
- 02
Work that shipped
Ask which flight units reached orbit or integration: mission name, launch vehicle or deployer, their subsystem ownership, and outcomes after commissioning including anomalies seen on the ground station pass.
- 03
Diagnosis under uncertainty
Test troubleshooting of thermal vacuum, vibration, and day-in-the-life test failures: how they traced intermittent bus resets, latch-ups, or attitude determination errors with limited telemetry.
- 04
Working across the org
Assess coordination with launch providers, licensing (FCC or ITU filings, orbital debris plans), payload customers, and AIT technicians under fixed launch manifest deadlines.
Pre-screening questions to ask Small Satellite Engineer candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Spacecraft that flew
3 questions01Explain your experience with the design and integration of satellite subsystems.
Listen forSubsystems they owned through integration, with whether the spacecraft was launched and how it performed.
Design work with no integration involvement, or spacecraft that never reached launch.
02What satellite platform or bus are you most familiar with?
Listen forPlatforms named with their real limitations, and a view on when to buy a bus rather than build one.
Platforms named with no operating experience, or buses treated as interchangeable.
03What is your experience with end-to-end mission design?
Listen forMission requirements traced through to subsystem design, with a capability dropped to keep the mission viable.
Mission design described at concept level, or requirements never traded against what the platform allows.
Tight constraints
4 questions04How do you ensure thermal management on a small platform?
Listen forPassive thermal design worked through with orbit and duty cycle, since active control is rarely affordable here.
Thermal treated as a later analysis, or active control assumed on a platform with no power for it.
05Can you discuss a project where you optimised power systems for a satellite?
Listen forGeneration, storage and duty cycle balanced across eclipse, with degradation over mission life accounted for.
Power budgeted on averages, or end-of-life degradation not included in the sizing.
06What is your experience designing for radiation tolerance in space?
Listen forCommercial parts used deliberately with mitigation such as watchdogs and memory scrubbing, and the risk accepted knowingly.
Radiation ignored because the orbit is low, or commercial parts used with no mitigation at all.
07How do you approach redundancy to ensure reliability?
Listen forRedundancy applied selectively where mass allows, with single point failures identified and accepted explicitly.
Redundancy assumed unaffordable with no analysis, or single point failures never identified.
Testing on a schedule
3 questions08Describe your process for conducting environmental testing.
Listen forVibration and thermal vacuum testing performed with levels justified, and a failure found during a campaign.
Testing cut for schedule with no risk assessment, or no test campaign that revealed a problem.
09Can you provide an example of troubleshooting a critical issue in a satellite system?
Listen forAn anomaly worked from limited telemetry with hypotheses ruled out in order, and the confirmed cause.
Anomalies attributed with no evidence, or investigations closed when the symptom stopped.
10What challenges have you faced during launch preparations?
Listen forReal integration and paperwork constraints named, with a late problem resolved before the launch window.
No launch campaign experience, or preparation described entirely from procedures.
Operations after launch
2 questions11Discuss your experience with ground station operations and data downlink.
Listen forLink budgets and contact windows understood, with data volume matched to what can realistically be downlinked.
Payload data volumes that exceed available downlink, or ground segment treated as somebody else's problem.
12Discuss your experience with regulatory compliance and licensing for satellite operations.
Listen forSpectrum licensing and debris mitigation treated as design constraints, with the deorbit requirement designed for.
Licensing treated as paperwork, or no deorbit plan considered during design.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Technical depth
35%5Quotes their own link and power budget numbers, names bus standards (CubeSat Design Spec, PC/104), and explains subsystem sizing choices.
Work that shipped
30%5Names specific flown or delivered spacecraft, their exact scope, and on-orbit telemetry results including what underperformed against prediction.
Diagnosis under uncertainty
20%5Walks through an anomaly board style investigation, fault tree, isolation steps, and the design or software fix that closed it.
Working across the org
15%5Describes managing ICDs, regulatory filings, and integration campaigns with providers while keeping schedule and mass margins honest.
These platforms accept risk deliberately, so the judgement is which risks to take. A one-way video screen asks what failed on orbit and whether they expected it.

Process basics
How long should a pre-screening round for this role take?
Fifteen minutes across eight to ten questions, answered async. Enough to establish what flew, test their constraint reasoning, and hear one on-orbit failure or anomaly they worked.
How does this differ from a larger spacecraft screen?
Weight cost and schedule constraints, commercial parts and accepted risk far more heavily. Large programme experience is valuable and can bring assumptions about margin that a small platform cannot afford.
Evaluating answers
What is the strongest signal when screening this role?
Something that failed on orbit. These platforms fail more often by design intent, and an engineer who has been through it can say whether the risk was one they knowingly accepted.
How do I judge their constraint thinking?
Ask what they gave up to meet the power or mass budget. Real answers name a capability that was cut. Anyone whose design met every requirement has not worked within a small platform's limits.
