-Responsible Engineering Authority (REA) for a delivery order of 4 satellite propulsion assemblies. Revised engineering drawings, assembly procedures, and test procedures to reflect best practices from previous delivery orders. Conducted pre-integration acceptance testing and post-integration functional testing. Tracked build schedule and cost vs. program targets and provided regular status updates to management.-Refined manufacturing processes by adopting manufacturing part numbers and digitizing work orders (team previously used engineering PNs and paper work instructions). Led all prop build and test activities for the program.-Generated and owned CAD models for multiple NASA science mission proposals. Worked with proposal managers to incorporate inputs from-- and provide essential outputs to -- subsystem responsible engineers.

Long Beach, Ca, Us

-Stage 2 Propulsion (engine + PPMS) primary console operator for LauncherOne. Participated in an 8-month rocket launch ops development test campaign. Responsible for S2 GUIs, procedures, LCC/warnings list creation, & review and approval of all S2-related hardware work, test ops, and flight ops. Sat on console for 25+ major test ops, nominal and mayhem flight sims, and VO’s first Demo Launch attempt.-Led a vibe test campaign for the N4 injector to provide confidence in the assembly for Flight 2 and beyond.-Continued to provide general support for injector, N4 engine, Stage 2, and Rocket build and test operations.

-Continuation of work performed under Virgin Galactic.-Newton 4 (N4) 2nd stage engine Responsible Engineer for the following projects: VO’s first-ever engine ATP campaign, VO’s first Stage Test campaign, and two separate engine development campaigns. Defined test matrices & autosequences, wrote assembly procedures and coordinated article builds, directed mate of propulsion hardware with integrated test articles and with test site GSE, wrote test plans & procedures, sat on console throughout test ops, led TSRR/TRRs and data reviews, and wrote an engine-to-rocket ICD that has since been adopted as the template for ICDs company-wide. -Developed VO’s 1st and 2nd stage injectors (part acquisition, build, checkouts, seal dev, test, and design iterations). Led a Newton 4 injector tuning campaign at NASA MSFC; researched and proposed 5 unique injector configurations, 4 of which demonstrated higher ηc* than the baseline configuration. Follow-up tests on the full N4 engine suggest an ηc* increase of 3-4% over the baseline configuration.-Assigned as primary Stage 2 Propulsion console operator for Virgin Orbit's first launch.-Served as Build Engineer for two development engine builds. Wrote all assembly and checkout instructions and continuously coordinated with technicians & engineers to incorporate layout and process improvements.-Defined propulsion components and instrumentation for rocket stages and engines allotted to VO’s flight test program. Published propulsion flight test assembly configurations in P&ID format.-Used NX and Ansys to design and analyze development and flight-grade propulsion hardware.

Tustin, Ca, Us

-Served as a propulsion development engineer on the LauncherOne program.-Led development of Boost Stage and Second Stage injectors, from piece-part acquisition, build procedure creation, and bench-top development testing (ambient and cryogenic leak and actuation tests; waterflow; seal development tests; etc.)-Served as RE for the Second Stage engine development test campaign. Oversaw test article build and checkouts; coordinated with test site for setup; and supported purge, coldflow, ignition, hotfire, and TEA-TEB chill tests.-Worked closely with vendors to design and secure timely delivery of custom parts (seals, springs, tooling).-Used NX to design tooling for build and test purposes, and to create drawing revs of dev and flight hardware.-Created procedures (build books, test matrices, safety procedures, etc.) to guide component build and test operations.

Falls Church, Va, Us

-Supported mechanical design, manufacturing, and systems verification of the James Webb Space Telescope (JWST) Mid Infrared Instrument (MIRI) cryocooler assembly.-Supported James Webb Space Telescope (JWST) Mid Infrared Instrument (MIRI) cryocooler assembly and delivery.-Determined which S/Ns to use on flight model and flight spare; designed inspection hardware and procedures; performed GD&T analysis of results; and presented findings to program management and the customer (NASA).-Coordinated release, qual, delivery, and requirements verification effort for drawings, tools, data, and flight hardware.-Appeared in company promotional materials.

Mojave, Ca, Us

-Conducted post-test hybrid motor analysis, including fuel regression and burn rate characterization. -Documented motor build process by creating build books and writing assembly, test, and analysis procedures. -Participated in carbon layups, assisted technicians with assemblies, and created a materials inventory system.

Hawthorne, California, Us

-Redesigned a TPS composite-resin system. Developed a test plan, manufactured test coupons, collected data with a LabView DAQ system, and used results to recommend a new resin infiltration procedure.-Provided general support for several R&D composite parts; wrote work orders and coordinated with the composite production team for execution, created build logs, digitized existing data, and assisted with a caul plate layup.

Pasadena, Ca, Us

-Compiled a searchable database of system level parameters from previously flown planetary, Earth orbiting, US, and foreign missions to be used by JPL’s A Team in their low Concept Maturity Level studies. -Supported the development of a new Discovery class interplanetary science mission proposal.

Moscow, Ru

-Worked with 80 international students to develop a mission to send a science probe to the comet Tempel 1; researched and proposed the sensor suite to be used on the probe in accordance with mission science objectives.-Sponsored by Rice University as one of nine American delegates. -Received first prize in the rocket modeling individual competition.
