Kurnool, India FixtureLabs Full time

Company Description

FixtureLabs offers an innovative AI-powered practice platform for mechanical engineering graduates to gain verified work experience through daily challenges in CAD, First Principles thinking, DFM, and FEA. The platform helps engineering professionals build a portfolio that showcases their capabilities to recruiters, providing a solution to the experience catch-22 faced by many entry-level engineers.


Role Description

This is a research-focused internship for a Mechanical Research Engineer at FixtureLabs. You’ll help advance our proprietary CAD Comparator—the engine that verifies student models against ground truth—by developing and validating geometry- and drawing-aware algorithms. The work is math-intensive and ideal for someone with strong critical thinking, a mechanical engineering foundation, and a love for turning theory into robust tools.


You will:

  • Develop Python pipelines, unit tests, and benchmarks; profile and harden edge cases (fillet chains, tiny features, near-coincident geometry).
  • Improve feature extraction and matching across CAD files and technical drawings (holes, fillets, GD&T, threads, tolerances, assemblies).


Qualifications

Required

  • BS or MS in Computer Science Engineering (or Mechanical).
  • Strong math: linear algebra, multivariable calculus, numerical methods, optimization, probability and statistics.
  • Programming in Python (NumPy, SciPy, pandas), unit testing, Git, clear code reviews.
  • First-principles problem solving, careful reasoning, clear written communication.


Preferred

  • Experience with OpenCascade or FreeCAD, or a major CAD API (SolidWorks API, Onshape API).
  • 3D geometry or vision tools: Open3D, OpenCV, PCL; basic meshing and FEA prechecks.
  • Light ML for clustering or anomaly detection (scikit-learn), basic optimization tuning.
  • Dev tooling: Jupyter, Docker, simple CI, profiling.
  • Portfolio or GitHub with CAD or geometry projects, small research writeups, or technical blogs.
