Job description

We are the leader in COTS FPGA-based high-performance computing. Our accelerator products employ the latest FPGA and SoC technology to provide computing capabilities far beyond what general purpose processors can provide.
Our firmware design team develops, maintains, and tests interfaces on high-performance FPGA computing systems. Members of the team regularly design both structural and behavioral HDL cores and models and simulate them with the latest simulation tools. Once hardware is available, the designer works to bring the design to life on the actual FPGA, ACAP, or MPSoC. As new boards are developed, design work is centered around interfaces between FPGAs and I/O devices. Of course, supporting data flow and algorithmic cores such as DSP cores are also a part of the design process.
These HDL efforts are then encapsulated and mapped into the Open CoreFire™ design space using Java. This Eclipse-based tool allows for a graphical approach to FPGA design, which empowers users to create powerful designs quickly and efficiently.
Enjoy the benefits of working for a small privately-held company with on-site hardware and software design, as well as on-site manufacturing and test. The close coupling of all aspects of design and production under one roof allows us to create products and systems at a rapid pace while maintaining the highest possible quality. The opportunity to interact with other departments on a daily basis provides a first-rate opportunity to further develop your career as you diversify your experiences.
Unique to the Annapolis experience, all Firmware Engineering Co-ops who work two semester terms back-to-back are offered an opportunity to work one semester with the Firmware team and the other with the Software team.
Essential Duties and Responsibilities
  • Help design and simulate FPGA interfaces to external devices on new platforms including in lab testing
  • Create example applications showcasing features of our FPGA platforms
  • Learn to develop for and utilize our Open CoreFire software tool
  • Create and maintain documentation for the interfaces and applications you develop
  • Strive to continuously improve the quality and reliability of our products
  • Design for the latest and future Xilinx and Intel FPGAs and ACAPs
  • Learn from, and work side-by-side with, the leading FPGA experts!

Requirements
  • Currently pursuing a bachelor's or master's degree in Computer Engineering or related field
  • U.S. Citizenship
  • Availability to work two consecutive terms (Summer/Fall or Spring/Summer)

In compliance with local laws regarding pay transparency, the hourly rate for this role is $24/hr to $31/hr; however, Annapolis Micro Systems considers several factors when extending an offer, including but not limited to, the role and associated responsibilities, a candidate's work experience, education/training, and key skills.
