Propulsion Engineer II - Hardware and Bus Systems

About This Role

As the Propulsion Engineer II – Hardware & Bus Systems, you will be a hands-on technical owner of the propulsion subsystem and propulsion hardware across Varda's fleet of spacecraft. You will help own and maintain the system architecture, generate analysis products, perform component sizing, propulsion software tool development, data review, detailed mechanical design, subsystem test, operations, and more for vehicles both on the ground and in orbit.

You will take ownership of assigned systems and work products within a fast-moving interdisciplinary engineering team. Your work will directly contribute to the development of current and future vehicles key to Varda's growth. You'll thrive in a hands-on environment, building technical breadth and steadily raising the bar on everything you touch.

Responsibilities

Support and maintain the Varda spacecraft propulsion system technical baseline, including P&IDs and system-level documentation

Design, analyze, and test Varda satellite bus propulsion flight hardware and components

Help scope and execute propulsion system block upgrades on operational vehicles — inclusive of both schematic and hardware changes — to increase reliability and launch cadence

Support definition of requirements and high-level propulsion architecture for future Varda vehicles; contribute to project plans, roadmaps, and milestones

Generate propulsion performance analysis products and document key requirements (propellant budgets, pressure ladders, fluid component sizing, structural & thermal limits, and more); deliver your outputs as key inputs to GNC, Mission Operations, Thermal, and other cross-disciplinary partner teams

Build Python scripts and spreadsheet tools to automate recurring analysis and test data review workflows

Execute detailed mechanical design of propulsion hardware and fluid system components; perform structural analysis using ANSYS, NASTRAN, or equivalent FEA tools

Author and review design documentation, engineering specs, build/integration/test procedures, and engineering memos

Support in-flight propulsion operations, including console support under senior engineer oversight

Disposition hardware nonconformances; support anomaly investigations and contribute to corrective actions

Basic Qualifications

B.S. in Aerospace Engineering, Mechanical Engineering, or a related discipline; equivalent professional experience considered (typically 1–3+ years)

3+ years of hands-on experience in propulsion or fluid systems design, build, and/or test for spacecraft or launch vehicles

Working knowledge of flight fluid system hardware: pressurized components, tubing, fittings, seals, valves, and instrumentation

Ability to read P&IDs; experience authoring P&IDs is a plus

Proficiency with CAD tools (e.g., CATIA, SolidWorks, NX) and PLM software

Experience authoring or executing operational procedures for ground test or flight campaigns

Demonstrated ability to take ownership of assigned technical tasks and drive them to resolution

Preferred Skills and Experience

3+ years of spacecraft or launch vehicle propulsion experience, including familiarity with satellite bus-level propulsion architectures (monopropellant, bipropellant, cold gas systems)

Experience building Python scripts or spreadsheet tools to automate propulsion analysis or data review workflows

Exposure to structural analysis using ANSYS, NASTRAN, or equivalent FEA tools applied to propulsion or fluid system hardware

Familiarity with technical drawing review and GD&T per ASME Y14.5 standards

Exposure to spacecraft-grade propellants including cryogenic, hypergolic, or high-test peroxide systems; awareness of cleanliness, handling, and safety requirements

Test, launch site, or in-flight operational experience on spacecraft or launch vehicles

Familiarity with 1D fluid modeling & analysis tools (GFSSP, REFPROP, or similar)

Strong technical communication skills- clarity and precision in work instructions, engineering specs, and engineering memos

Pay Range

Salary Range: Eng II: $119,543-$152,749/per year

This role is on-site in El Segundo, CA

Leveling and base salary is determined by job-related skills, education level, experience level, and job performance

You will be eligible for incentives in the form of stock options and/or long-term cash awards
