As AI writes more of the world's code, the bottleneck in software has shifted from writing code to verifying it works, and AI cannot verify its own work with certainty. Code Metal takes a fundamentally different approach: constrain AI to what it does reliably, verify every step independently of the model using formal methods, and keep engineers in the loop on the decisions that matter. The result isn't code that probably works - it's code that is provably correct, with auditable proof. Customers including the U.S. Air Force, L3Harris, RTX, and Toshiba use Code Metal to modernize legacy code, optimize performance on real hardware, and move prototypes to production, fast. Founded in 2023 with offices in Boston and San Francisco, Code Metal is funded by Accel, Salesforce Ventures, B Capital, Smith Point Capital, J2 Ventures, Shield Capital, Overmatch, RTX, and others. \nLearn more at codemetal.ai.\nThe Role\nWe're building a new generation of translation tools that turn Python algorithm code into correct, deployable C++ for embedded systems. They combine classic compiler techniques with generative AI and modern verification. Analysis and lowering carry most of the work. AI covers the cases analysis can't, and testing and verification check the result.\nYou'll lead the architecture of the translation pipeline, from parsing and semantic analysis through intermediate representation (IR) design to C++ code generation. That means deciding how to keep Python's semantics exact when the output is statically typed C++.\nCore Responsibilities\nDesign and evolve the pipeline's IR, analysis passes and C++ code generation, keeping the core independent of any one source language.\n\nBuild type inference and lowering for dynamic Python features: arbitrary-precision integers, exceptions, generators, containers, and calls to the standard library and third-party libraries.\n\nMake semantic equivalence measurable, through differential testing against CPython, conformance suites and fuzzing.\n\nIntegrate LLM-assisted generation where analysis falls short, with structured outputs and checks that catch its mistakes.\n\nCollaborate with verification and domain specialists to bring static analysis and formal methods into the pipeline.\n\nSet engineering standards for the codebase: tests, CI/CD, reproducible builds and code review.\n\nRequired Qualifications\n7+ years of professional software development in C++ and/or Python, shipping to real users.\n\nHands-on experience building a compiler, transpiler, interpreter or language runtime: the end-to-end pipeline, not just one pass.\n\nDeep understanding of parsing, AST and IR design, type systems, IR transformations and code generation.\n\nExperience with compiler infrastructure such as Clang/LLVM, MLIR, GCC or equivalent.\n\nStrong modern C++: templates, value semantics, undefined behaviour, and how source code maps to the machine.\n\nSolid delivery fundamentals: code review, testing, CI/CD and build systems.\n\nA track record of leading large technical projects in a team, and of turning stakeholder needs into designs.\n\nEligible to obtain and maintain an active U.S. Top Secret security clearance\n\nPreferred Qualifications\nExperience with dynamic-language implementation or analysis (CPython internals, PyPy, Cython, Numba, mypyc, or type inference for dynamic languages).\n\nDifferential testing, fuzzing, symbolic execution, or formal verification (e.g. Z3, Coq, TLA+).\n\nExperience applying LLMs to code generation or program repair.\n\nEmbedded, heterogeneous (FPGA/GPU) or resource-constrained targets.\n\nFamiliarity with DSP, RF, communications or other compute-intensive domains.\n\nA current security clearance, or the ability to obtain one (US citizenship required for cleared work).\n\nBenefits\nPay depends on experience, but we strive to be at the upper end of the salary range\n\nHealth care plan with 100% premium coverage, including medical, dental, and vision\n\n401k with 5% matching\n\nPaid Time Off (uncapped vacation, plus sick and public holidays)\n\nFlexible hybrid or remote work arrangement\n\nRelocation assistance for qualifying employees\n\nWage Transparency - The salary range for this role is not a guarantee of compensation or salary, as the final offer amount may vary based on factors including, but not limited to, individual proficiency, skills, experience, and location.\nWe are an equal opportunity employer. US Citizenship may be required for certain project assignments involving security clearance.\nPursuant to the San Francisco Fair Chance Ordinance, we will consider for employment qualified applicants with arrest and conviction records.","description_format":"text","description_chars":4693,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":true,"languages":[]},"benefits":["401k plan","Relocation assistance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Embedded Software & RTOS","Code Intelligence","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-11-05T02:52:51Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":46,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-11-06T05:58:05Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":false},"html_url":"https://alion.io/job/code-metal-staff-software-engineer-compiler","json_url":"https://alion.io/job/code-metal-staff-software-engineer-compiler.json","meta":{"generated_at":"2026-11-06T23:51:04Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","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":3919,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":716539},"rest":"https://alion.io/mcp/rest/get_company?id=716539"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcode-metal-staff-software-engineer-compiler"},{"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%2Fcode-metal-staff-software-engineer-compiler"},{"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%2Fcode-metal-staff-software-engineer-compiler"},{"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/code-metal-staff-software-engineer-compiler\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcode-metal-staff-software-engineer-compiler"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3784440}},{"tool":"search_jobs","arguments":{"company":"codemetal.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3784440},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
