Our mission is to remove the limits of scale, hardware, and cost that hold back innovation, so the people solving humanity's hardest problems can move faster.\nWe're building a new kind of software stack: a hardware-agnostic platform that makes every system - from a laptop to a supercomputer - feel like one seamless engine. Developers can write once, run anywhere, and get state-of-the-art performance across any chip, any cloud, at any scale. It's a complete rethink of how software and hardware interact - designed for the era beyond Moore's Law.\nWe're not looking for the comfortable or the conventional; we're looking for the bold. The engineers who crave frontier problems, who want to bend the limits of what's possible, who see infrastructure not as a constraint but as a canvas. If you want to build the foundation for the next era of AI and change what humanity can achieve in the process, join us.\nAbout the Role\nAs the founding member of our Developer Experience (DevX) team, you will be instrumental in shaping how engineers interact with our compiler infrastructure. You'll build the tools that give developers deep visibility into system performance-from profiling and debugging capabilities to hardware introspection interfaces. Your work will bridge the gap between our core compiler technology and the engineers who use it, transforming complex system data into actionable insights.\nThis role sits at the intersection of systems programming and developer tooling. You'll work closely with our compiler engineers to surface server-side telemetry through intuitive client-side interfaces, ultimately creating a best-in-class development experience for our users.\n\nWhat You'll Do\nDesign and build developer tools for profiling, debugging, and performance introspection across our compiler stack.\nCreate client-side tooling that transforms server-side compiler telemetry into clear, actionable information for engineers.\nDevelop interfaces that expose hardware performance metrics, and interrupt data in meaningful ways.\nBuild GPU debugging capabilities and visualization tools to help engineers understand execution on heterogeneous hardware.\nDefine formats and protocols for debug information exchange, working with standard debugger formats (DWARF, JTAG) and object file formats (ELF, COFF).\nCollaborate with internal engineering teams to understand their needs and iterate on tooling, with a path toward external customer-facing tools.\n\nEssential Skills and Experience:\n3+ years of professional experience in systems-level software development.\nStrong proficiency in C++ with experience writing performance-critical code.\nWorking knowledge of assembly language and low-level debugging techniques.\nFamiliarity with debugger formats (DWARF, JTAG) and object file formats (ELF, COFF).\nUnderstanding of profiling methodologies and performance analysis tools.\nAbility to work on-site at our Toronto or Santa Clara office.\n\nPreferred Skills and Experience:\nExperience with GPU programming and debugging (CUDA, ROCm, or similar).\nExperience with OS-level interfaces including I/O subsystems and interrupt handling.\nBackground in compiler development or toolchain infrastructure.\nExperience building developer-facing tools or IDEs.\nContributions to open-source debugging or profiling tools.\nWhy Join Lemurian Labs\nWork at the intersection of compilers, hardware, and developer experience - a genuinely rare combination.\nBuild tools that developers will rely on every day, with real ownership from day one.\nCompetitive compensation including equity, medical/dental/vision, retirement savings, and wellness benefits.\nLemurian Labs is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees, regardless of gender identity, race, ethnicity, sexual orientation, disability status, age, or background.\nCompensation depends on experience and geographic location and will be narrowed during the interview process. Additional benefits include equity, company bonus opportunities, medical, dental, and vision coverage, a retirement savings plan, and supplemental wellness benefits.","description_format":"text","description_chars":4261,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Retirement plans"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-10-13T16:15:46Z"}],"visa":[],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.271,"p_room":0.28,"age_days":248,"expected_fill_days":36,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-19T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/lemurian-labs-senior-developer-tools-engineer","json_url":"https://alion.io/job/lemurian-labs-senior-developer-tools-engineer.json","meta":{"generated_at":"2026-10-19T06:36:41Z","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":4180,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-20T00:00:00Z"}},"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":679667},"rest":"https://alion.io/mcp/rest/get_company?id=679667"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flemurian-labs-senior-developer-tools-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%2Flemurian-labs-senior-developer-tools-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%2Flemurian-labs-senior-developer-tools-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/lemurian-labs-senior-developer-tools-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flemurian-labs-senior-developer-tools-engineer"}]}
