About the role

This is a rare opportunity to do foundational analytical work on hardware that will operate in the most unforgiving environment imaginable.
This position will be open until it is successfully filled.
True Anomaly is committed to equal employment opportunity on any basis protected by applicable state and federal laws.

Responsibilities

Own engine balance and cycle modeling: Develop and maintain integrated 1D engine/thruster cycle models in ROCETS, Sinda/Fluint, or equivalent tools to predict system-level performance, identify design sensitivities, and support architecture trade studies from concept through flight.
Lead injector analysis and sizing: Apply first-principles and empirical methods to size injector elements, predict atomization and mixing efficiency, and validate designs against performance targets.
Translate model outputs into actionable design guidance for hardware engineers.
Assess and mitigate combustion instability: Perform stability assessments using analytical and numerical methods - including acoustic mode analysis, Rayleigh criterion evaluation, and sensitivity studies - and recommend design mitigations such as acoustic cavities, baffle configurations, and injector pattern modifications.
Apply CFD to combustion dynamics: Leverage CFD tools (Ansys Fluent, Reacting Flow, or equivalent) to characterize combustion dynamics, flame structure, mixing efficiency, and hot-gas-side heat flux distributions, feeding results back into design and stability assessments.
Develop thrust chamber thermal-fluid models: Build conjugate heat transfer and regenerative cooling models to predict wall temperatures, heat flux profiles, and coolant pressure drop, ensuring hardware margin across the operating envelope.
Partner with designers and suppliers: Work directly with thruster designers and suppliers to interpret test data, validate models against hot-fire results, and close the loop between analysis and hardware performance.
Build lightweight design tools: Create accessible tools and parametric models that allow hardware responsible engineers to quickly size components and evaluate performance without requiring deep analysis expertise.
Define and execute evolutionary analysis plans: Structure the analysis program to mature in lock-step with hardware development and testing - increasing fidelity as data becomes available and design decisions demand it.
Establish analytical best practices: Define processes for in-depth analysis, second-set-of-eyes reviews, and parameter input standards. Build a culture of analytical rigor across the propulsion team.

Requirements

Bachelor's degree in Mechanical or Aerospace Engineering.
12+ years of professional experience in liquid rocket engine or thruster analysis.
Experience with 2-phase fluid modeling in propulsion systems.
Experience with conjugate heat transfer and regenerative cooling analysis.
Familiarity with the full thruster development process, from concept trade studies through hardware qualification.
Excellent written and verbal communication skills, including the ability to present complex analysis clearly to non-specialist stakeholders.
Proficiency across multiple propulsion analysis tools: ROCETS, Sinda/Fluint, Thermal Desktop, GFSSP, Ansys Fluent, Flow-3D, or equivalent.
Direct experience supporting thruster development test campaigns, including pre-test predictions and post-test model validation.
Track record of innovative problem-solving in coupled thermo-fluid-structural problems.
Experience in a startup or similarly resource-constrained, high-tempo environment.
Engine balance and cycle modeling: Demonstrated hands-on experience building and running integrated 1D engine cycle models in ROCETS, Sinda/Fluint, GFSSP, or directly comparable tools.
Injector design and sizing: Significant experience sizing injector elements (e.g., impinging, coaxial, swirl) using analytical methods and CFD, with demonstrated ability to predict and improve mixing efficiency and atomization.
Combustion instability assessment and mitigation: Proven experience identifying instability risk in thruster designs, performing acoustic and stability analyses, and recommending or validating mitigation strategies through analysis and/or testing.
U.S. Citizen, eligible for DoD Secret or TS/SCI clearance.
Combustion CFD: Experience applying CFD (Ansys Fluent, Reacting Flows, or equivalent) to combustion dynamics, including reacting flow simulations and heat flux prediction.

Skills

Master's or PhD in Mechanical or Aerospace Engineering with an analysis focus (advanced degrees count toward years of experience).
ROCETS, Sinda/Fluint, Thermal Desktop, GFSSP, Ansys Fluent, Flow-3D, or equivalent.

Compensation

Base Salary: $175,000 to $305,000
Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, location, and experience.

Benefits

Equity + Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave

Company info

True Anomaly delivers decisive capabilities for space superiority.
We build autonomous spacecraft, advanced payloads, mission software, and space-based interceptors - enabling the U.S. and its Allies to secure the space environment and counter threats from the ultimate high ground.
What would it take? We challenge assumptions to deliver ambitious results.
It's the people. Our team is our competitive advantage and we are better together.
As a Staff Engine Performance Analyst at True Anomaly, you will be the analytical backbone of our propulsion development program s.
You will build high-fidelity models of thruster systems - from propellant feed lines through combustion and nozzle expansion - and work hand-in-hand with thruster designers to optimize hardware before it's ever built.
Your expertise in engine balance modeling, injector design and sizing, and combustion stability will directly determine the performance and reliability of the next generation of in-space propulsion systems.
