Neuralink Materials Engineer at Neuralink responsible for building and validating explicit dynamics FEA models and owning mechanical testing pipelines for implant reliability. Collaborates with cross-functional teams to ensure implant meets impact, fatigue, and seal integrity requirements.

Responsibilities

We are looking for a Mechanical Engineer who owns the full simulation-to-test loop for implant mechanical reliability. This person will build explicit dynamics FEA models, design and run physical tests, calibrate material models against experimental data, and validate predictions. You will work closely with materials engineers, microfabrication, and cross-functional reliability teams to ensure the implant meets impact, fatigue, and seal integrity requirements.
Build, refine, and validate explicit dynamics Finite Element Analysis (FEA) models (LS-DYNA, Abaqus/Explicit) to predict mechanical response under high-strain-rate impact loading.
Own the in-house mechanical testing pipeline end-to-end: design fixtures, prepare specimens, run tests (servo-hydraulic, drop tower, DIC), and correlate results to simulation using quantitative metrics (CORA, force-displacement overlay, DIC contour comparison).
Translate physical test data into constitutive model inputs: calibrate material cards, optimize parameters, and deliver validated simulation files.
Coordinate test projects (SHPB, DMA, abuse testing) and own data quality from external sources.
Extend validated impact models to adjacent reliability domains: burst/cyclic pressure testing, vibration fatigue, and seal interface simulation.
Support cross-functional reliability programs including thermal modeling, RH/leak modeling, and accelerated lifetime testing as needed

Qualification

MS or PhD in Mechanical EngineeringAbility to work autonomouslyExpected Compensation

Required

MS or PhD in Mechanical Engineering, Materials Science, or related field.
2+ years of hands-on experience with explicit dynamics FEA (LS-DYNA, Abaqus/Explicit, or similar) - not static/modal only.
2+ years of hands-on experience with mechanical testing (tensile testers, DMA, servo-hydraulic frames, or similar equipment).
Experience with polymer or composite material characterization, including rate-dependent and temperature-dependent behavior.
Hands-on experience with mechanical assembly, fabrication, or building and calibrating test equipment.
Proficiency in mechanical design (SolidWorks or similar CAD software).
Familiarity with relevant test standards (ASTM, IEC).
Ability to work autonomously: define test plans, build fixtures, run tests, analyze data, and present conclusions

Preferred

Direct experience with high-strain-rate testing (SHPB, drop tower).
Experience with Digital Image Correlation (DIC) or full-field strain measurement.
Experience with constitutive model calibration and parameter optimization (fitting test data to LS-DYNA material cards such as MAT_SAMP-1, MAT_024, or cohesive zone models).
Medical device or aerospace reliability background (DV/V&V, FDA regulatory context).
Python for data processing and automation.
Experience correlating simulation to physical test data using quantitative metrics (CORA, force-displacement overlay, DIC contour comparison).
Experience calibrating and troubleshooting lab instrumentation.
