Efficient is looking to solve the problem of developing the world’s most energy-efficient general-purpose computer processor, using 100x less energy than state of the art commercially available ultra-low-power processors.

Requirements

  • 3+ years of C/C++ experience
  • Deep knowledge of at least one embedded platform, such as MSP430, STM32, Ambiq Apollo, PIC32, or similar
  • Experience developing and deploying applications under resource constraints
  • Experience using non-standard build environments and compiler toolchains, especially for embedded systems
  • Experience using industry standard development and debugging tools for embedded development
  • Experience using LLVM, MLIR, GCC, or a similar compiler framework to develop compiler passes
  • Experience building TinyML models and deploying models under severe resource constraints (e.g. limited memory)

Responsibilities

  • Independently design and implement complex embedded applications based on customer requirements, specifications, and existing code.
  • Drive application optimization using Efficient’s compiler and software stack targeting the Fabric.
  • Deploy and validate applications on the Fabric across software simulation and FPGA emulation environments.
  • Own performance and energy-efficiency analysis, developing benchmarks and methodologies to evaluate applications against customer requirements.
  • Identify, reproduce, and distill issues into minimum-viable test cases, conveying precise feedback to the compiler team.
  • Collaborate deeply with the compiler team to test, debug, and refine compiler features.
  • Contribute advanced optimizations to frameworks and libraries in domains such as DSP and machine learning.

Other

  • Must be an excellent embedded engineer with 8+ years of work experience
  • Strong attention to detail, good work ethic, ability to work on multiple projects simultaneously, and good communication skills
  • Good problem solving skills
  • 401K match, company-paid benefits, equity program, paid parental leave, and flexibility
  • Competitive compensation and benefits package
