Software Engineer - Grid Generation 

Exa Corporation is a global innovator of simulation driven engineering
solutions.  We develop cutting-edge simulation and design optimization software
products that apply to a range of industries including ground transportation,
aerospace, motorsports, chemical, biomedical and electronics.

Position Profile:

Exa Corporation’s growing Software Development team is seeking a developer with
a strong background in computational geometry, parallel processing and
object-oriented development in C++. You will be a key member of this team
responsible for developing the PowerFLOW grid generator which supports Exa's
Computational Fluid Dynamics (CFD) simulation technology. The PowerFLOW grid
generator is a unique application that handles extremely complex and variable
quality geometry, automatically generating very large scale grids for fluid flow
simulation, without requiring any geometry simplification. 

Role & Responsibilities:

We seek to dramatically improve the performance of the PowerFLOW grid generator,
and integrate it directly with the simulator to enable new functionality such as
moving geometry and adaptive grid resolution, and your expertise will make a
major contribution to this critical task. The focus of this position will be to
enhance the grid generation technology, including development of a robust
Boolean engine, parallelization of the grid generator and integration with the
PowerFLOW simulator.

You should have a background in developing 3D geometry software, in an area such
as CAE (Computer Aided Engineering) volume/surface meshing, CAD (Computer Aided
Design) modeling, computer graphics, or other computational geometry
implementations. Experience with numerical simulation techniques is a definite
plus. Strong software development skills will be needed to develop, enhance, and
maintain efficient and robust software, including parallelization techniques
(via MPI). The application's geometry components deal with surface
tessellations, Boolean operations on polyhedra, polygon operations, search
optimization, etc. Responsibilities will include software requirements analysis,
design, project planning, implementation and testing.

Requirements:

•MS or PhD in Computer Science, Mathematics, Mechanical, Aerospace,  Electrical
Engineering or related discipline
•1 - 2 years software engineering experience
•Expert C++ coding skills
•A background in developing software implementing 3D geometry methodology,  
e.g. in computer graphics and/or CAE mesh data structures and algorithms.
•Proven experience in deploying object-oriented design (OOD) in the development
of complex software systems
•Strong independent problem solving ability
•Excellent English verbal/written communication skills
•Experience with numerical simulation techniques is a definite plus
•Experience with parallelization techniques (e.g. MPI) a plus

Compensation and Benefits:

Exa offers competitive compensation, stock options  and a dynamic, growing
company environment.  Benefits include comprehensive coverage for medical,
dental, life, disability, flexible spending accounts, 401K savings plan with
company match, vacations and holidays, flexible work schedule and free access to
our on campus fitness club, classes and amenities center.
