Do you want to turn rocket engine test data into the decisions that make flight hardware real?

PAVE Space is building
LYOBA
, a heavy kick stage moving up to 4-ton payloads from LEO to high-energy orbits in under 24 hours. None of that works unless our propulsion, fluidics, structures, and spacecraft systems are tested, understood, and improved fast. That starts with clean, trusted, actionable test data.

That’s the job.

We are scaling up propulsion and spacecraft test campaigns, from component-level checks to full engine and system tests. Every test generates large volumes of sensor data: pressure, temperature, thrust, flow, vibration, strain, valve timing, DAQ signals, and more.

You’ll build the processing, analysis, and reporting workflows that turn raw data into engineering insight on a timeline measured in hours or days, not weeks.

Your work will directly influence whether hardware is redesigned, accepted, retested, or fired again.

• Build and maintain automated test data processing pipelines
• Clean, synchronize, filter, calibrate, and validate raw test data
• Process data from propulsion, fluidics, structural, thermal, and system-level tests
• Generate post-test plots, dashboards, reports, and engineering summaries
• Detect sensor issues, timing errors, drift, noise, saturation, and anomalies
• Compare test results against models, requirements, and acceptance criteria
• Support hot-fire, cold-flow, pressure, leak, vibration, thermal, and functional testing
• Work with test, propulsion, fluidics, structures, GNC, and systems engineers to interpret results
• Maintain traceable datasets, scripts, reports, and test records
• Help define instrumentation, sampling rates, data channels, and test-data requirements before campaigns

• 2+ years hands-on experience processing engineering test data
• Strong Python and/or MATLAB skills
• Experience with time-series data, filtering, signal processing, and sensor calibration
• Ability to work with real hardware test data, not just clean textbook datasets
• Solid engineering fundamentals in at least some of:
• thermodynamics
• heat transfer
• structural mechanics
• vibration or dynamics
• Experience producing clear plots, reports, and technical conclusions
• Strong attention to detail, traceability, and data quality

• Aerospace, automotive, propulsion, high-pressure, or high-reliability test experience
• Experience with DAQ systems such as LabVIEW, National Instruments, Dewesoft, HBM, Beckhoff, or similar
• Experience with propulsion sensors: pressure transducers, thermocouples, flow meters, load cells, strain gauges, accelerometers, valve position sensors
• Experience with hot-fire, cold-flow, TVAC, vibration, structural, or pressure testing
• SQL, databases, or structured test-data management
• Uncertainty analysis and measurement error propagation
• Familiarity with CFD, FEA, Modelica, Ecosim Pro, Simulink, or system simulation tools

• You like finding the story hidden inside messy test data
• You care about whether a sensor is lying before anyone makes a design decision from it
• You can write scripts that other engineers can actually reuse
• You understand that a plot is only useful if it leads to a decision
• You are comfortable moving between code, physics, instrumentation, and hardware
• You want your work to influence real tests, real engines, and real spacecraft

This is hard, early, and fully on-site in Villeneuve, VD, close to our test site in Chavalon, because we have a strong on-site hardware culture. Some tests will not behave as expected. Some data will be noisy, incomplete, or surprising. That is exactly why this role matters.

What makes it worth it: you will help build the data backbone behind one of the most ambitious propulsion programs in Switzerland.
