The ideal candidate has shipped production LLVM compiler pipelines at a semiconductor company, has hands-on embedded bring-up experience, and brings formal verification rigour to safety-critical real-time systems.\n\nResponsibilities: \nOwn custom LLVM backend passes, instruction selection (SelectionDAG / GlobalISel), MIR-level optimisations, and register allocator improvements for real-time execution paths.\nBuild compiler fuzzing infrastructure and formal verification frameworks (Alive2 / SMT), with zero miscompilations in safety-critical pipelines.\nImplement device drivers and protocol stacks (USB, SPI, I2C, UART, PCIe, CAN) for real-time biosignal acquisition.\nWork with Linux kernel subsystems, RT-PREEMPT, SCHED_FIFO, and kernel modules for deterministic biosignal scheduling.\nProfile and optimise across CPU / GPU architectures using perf, gdb, Nsight, rocprof, valgrind, and eBPF.\nAuthor SRDs and SDDs; lead design reviews and mentor engineers across C++, LLVM, and embedded systems.\nCollaborate with hardware teams on silicon bring-up and BSP development ahead of tape-out.\n\nRequirements: \n12+ years in system-level C++ spanning GPU compiler engineering, embedded firmware, and kernel-adjacent work.\nDeep LLVM expertise: SelectionDAG, GlobalISel, MIR, register allocator, TableGen, custom pass development.\nEmbedded Linux / RTOS (FreeRTOS, Zephyr) with hard real-time constraints; firmware bring-up across SPI / I2C / USB / PCIe / eMMC.\nGPU programming: CUDA / HIP; GPU execution model expertise (warp scheduling, register files, occupancy).\nCompiler correctness: fuzzing harnesses, formal verification (Alive2 SMT/SAT), differential testing.\nAdvanced debugging: gdb, Lauterbach JTAG, logic/protocol analysers, AddressSanitizer.\n\nGood to have: \nFPGA design (Verilog / VHDL) and assembly-level programming (PTX, GCN, SASS, x86 8051).\nDSP fundamentals or biosignal pipeline experience (EEG, EMG).\nSkills\nC++, LLVM, Linux, RTOS, compiler, embedded, firmware, kernel","description_format":"text","description_chars":2253,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Health Care","Web Design","Neurotech & Neuromodulation"],"lifecycle":[{"event":"open","at":"2026-10-24T16:36:15Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":2,"expected_fill_days":27,"reasons":["seen:2","velocity","win:early"],"computed_at":"2026-10-27T05:46:45Z"},"pay":null,"html_url":"https://alion.io/job/anthriq-principal-compilers-engineer","json_url":"https://alion.io/job/anthriq-principal-compilers-engineer.json","meta":{"generated_at":"2026-10-27T07:13:35Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":7671,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-28T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3795523},"rest":"https://alion.io/mcp/rest/get_company?id=3795523"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fanthriq-principal-compilers-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fanthriq-principal-compilers-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fanthriq-principal-compilers-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/anthriq-principal-compilers-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fanthriq-principal-compilers-engineer"}]}
