You will be working very closely with a small team of very high caliber developers with diverse expertise. Positions are in Littleton, MA or San Jose, CA. 

Principal Engineer/Architect

We are looking for a talented software engineer with deep electrical engineering and mathematics expertise to join our team. You will contribute to our core statistical circuit simulation engine. You will:

  • learn our method for simulating spice circuits with statistical variance analytically instead of using sampling.

  • learn our methods and tools for development, database access, debug, profiling and analysis used to develop heavily multi-threaded and massively distributed solutions.

  • be responsible for researching and applying mathematical concepts and prototyping new algorithms and approaches to solve complex non-linear problems.

  • define, develop and test new algorithms into efficient and robust production software using C/C++

  • architect the next generation numerical analysis engine

The ideal candidate has the following skills and experience:

  • Ability to work with a remote/distributed team.

  • Good communication skills a must.

  • Must have extensive C/C++ experience

  • Must have knowledge of BLAS/LAPACK numerical math kernels as well as commercial implementations such as (GOTO/MKL/ACML/etc). MKL and/or ACML are big pluses.

  • Must have extensive numerical analysis background

  • Must have experience implementing SPICE and SPICE-like simulators & algorithms.

  • Must be knowledgeable and have experience using SPICE simulators (Berkeley SPICE, HSPICE, ELDO, etc). 

  • Must have in depth experience with the underlying math, algorithms, etc. of SPICE simulation,

  • Must have familiarity with the BSIM model. Experience with BSIM-CMG or TMI a plus.

  • Must have experience with transistor/RC circuit analysis.

  • Experience with Mathematica for prototyping and experimentation a big plus.

  • Experience with multi-threading and distribution a definite plus.

  • Experience with transistor circuit minimization and optimization a plus.

  • Cell characterization experience a plus

  • Memory characterization experience a plus.

  • Custom memory development experience a plus

  • Knowledge and experience with x86_64 assembly/C/Tcl/Python are pluses.

This position requires a Ph.D. in Applied Mathematics or Computer Science, and 5+ years experience, or a M.S. with 10+ years experience.
