Efficient’s patented technology uses 100x less energy than state of the art commercially available ultra-low-power processors and is programmable using standard high-level programming languages and AI/ML frameworks. This level of efficiency makes perpetual, pervasive intelligence possible: run AI/ML continuously on a AA battery for 5-10 years. Our platform’s unprecedented level of efficiency enables IoT devices to intelligently capture and curate first-party data to drive the next major computing revolution\nWe are seeking a Senior Compiler Engineer to join our growing team. The Compiler Engineer will contribute to the design and implementation of an embedded machine learning (ML) system stack and TinyML applications to run on the world’s most energy-efficient programmable processor. This position is a unique opportunity to develop applications for cutting-edge hardware as part of a highly interdisciplinary team, helping to demonstrate the value of Efficient’s breakthrough technology. If you are an engineer who wants to be part of an intensely skilled team and wants to have an immediate impact building the next generation of energy-efficient ML applications, we want to talk with you!\nKey responsibilities\nDevelop new compiler features to improve overall hardware efficiency while maintaining programmability. These may relate to:- Efficient’s new dataflow ISA\n- Memory analysis and ordering Hardware constraints such as timing and power consumption\n- Place-and-route of applications onto Efficient’s fabric\n- Visualization\n- Programmer debugging tools\n\nWrite unit and integration tests to uncover functional- and performance-related compiler bugs.\nWork with various machine-learning frameworks to compile models to our custom hardware.\nDebug and fix functional and performance issues of the compiler system.\nCollaborate with the hardware and physical design team to understand and improve hardware architecture and propose future improvements.\nWork closely with the application development team to understand the problem domain and deliver optimized compiler solutions.\nRequired qualifications & experience requirements\n6+ years of experience with C++.\nBachelor's/Master's degree in CS or related field.\nFamiliarity with compiler frameworks such as GCC, LLVM, and/or MLIR.\nUnderstanding of computer architecture and optimization.\nExperience using industry standard development and debugging tools including GDB.\nStrong attention to detail, good work ethic, ability to work on multiple projects simultaneously, and good communication skills.\nGood problem solving skills.\nAdditional qualifications considered\nFamiliarity with FPGA-compilation and/or PnR algorithms.\nExperience with verilog, system verilog, or VHDL.\nKnowledge of computer architecture.\nWe offer a competitive base salary for this role, generally ranging from $160,000 to $230,000, plus a 10% annual bonus, meaningful equity, and comprehensive benefits. Final compensation will depend on experience, level, and location, with flexibility for the right candidate.\nWhy Join Efficient?\nEfficient offers a competitive compensation and benefits package, including 401K match, company-paid benefits, equity program, paid parental leave, and flexibility. We are committed to personal and professional development and strive to grow together as people and as a company.","description_format":"text","description_chars":3436,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["401k plan","Equity","Parental leave","Professional development"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Hardware","Processors, MCUs & AI Chips"],"lifecycle":[{"event":"open","at":"2026-09-26T15:21:38Z"}],"liveness":{"score":19,"band":"cold","label":"Long shot","p_open":1,"p_active":0.422,"p_room":0.45,"age_days":54,"expected_fill_days":31,"reasons":["conf:0","velocity","win:tail"],"computed_at":"2026-09-27T05:45:00Z"},"pay":{"stated_usd_annual":230000,"is_top_pay":true},"html_url":"https://alion.io/job/efficient-computer-senior-compiler-engineer","json_url":"https://alion.io/job/efficient-computer-senior-compiler-engineer.json","meta":{"generated_at":"2026-09-28T04:51:04Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":3172,"day_limit":5000,"remaining_today":1828,"minute_limit":60,"resets_at":"2026-09-29T00:00:00Z"}}}
