ABOUT ASTROBASE SPACE TECHNOLOGIES
Astrobase Space Technologies is an early-stage Bengaluru company building a two-stage orbital launch vehicle. Our engine is a LOX–methane full-flow staged-combustion engine. The Astrobase Propulsion team is looking for experienced and passionate professionals who can own the vehicle's stage fluid and propulsion systems from design to flight.
KEY RESPONSIBILITIES
-
Own the engine P&ID: propellant, cooling, purge, pressurisation, ignition, bleed and instrumentation circuits, with valve functions and failure states.
-
Build and maintain the steady-state power balance of the fuel-rich and oxidiser-rich preburner–turbopump loops; close the pressure schedule and allocate pressure drop to each component.
-
Map the operating envelope: throttle range, mixture-ratio excursions, pump inlet NPSP margins, and stage-interface pressures and temperatures.
-
Model start, shutdown, chill-down, priming and waterhammer transients; set valve timing and sequence constraints with the controls team.
-
Run sensitivity and Monte Carlo studies on component scatter and engine-to-engine variation; size calibration and trim orifices.
-
Write requirement specifications for pumps, turbines, preburners, valves, lines and heat exchangers, and the engine-to-stage and engine-to-stand ICDs.
-
Issue pre-test predictions and redlines; correlate the model with water, LN2 and hot-fire data and keep a model-validity record.
-
Run cycle trades for each engine iteration and record each decision with the analysis behind it.
DESIRED QUALIFICATION
-
B.E./B.Tech/M.E./M.Tech in Mechanical or Aerospace Engineering.
-
Min. 5+ years in liquid rocket engine system analysis or propulsion fluid-system design.
-
Has built a pump-fed engine cycle model (gas-generator, staged-combustion, expander or electric-pump) and correlated it with test data.
-
Turbopump power matching, pump and turbine maps, and real-fluid behaviour of LOX and methane near saturation.
-
Cycle and fluid-network tools: NPSS, ROCETS, EcosimPro/ESPSS or GFSSP; NASA CEA.
-
Python or MATLAB for analysis and test-data reduction.
PREFERRED QUALIFICATION
-
Transient start and shutdown models on hardware that was later fired.
-
Staged-combustion experience, especially oxidiser-rich preburner circuits.
-
Cryogenic line chill-down, two-phase flow and geysering analysis.
-
Model verification and credibility practice per NASA-STD-7009B (Standard for Models and Simulations); NASA SP-125 design methods.
-
Has set test objectives and instrumentation for a component or engine test.
WHAT WE OFFER
-
Salary: ₹24–36 LPA fixed CTC, variable pay based on experience and role fitment.
-
Attractive early-stage stock options (ESOPs).
-
Group health insurance: employee, spouse, children and parents.
-
Insurance: term-life and personal-accident cover.
-
Work environment: Challenging, stimulating, research-driven work solving rocket problems every day with a great team. We have a good time, and unlimited coffee.
