We're looking for a developer to work on the parsers and compilers at the center of it.\nThe Role\n.txt builds structured generation: we make language models produce output that follows a given format, by deciding at every decoding step which tokens are allowed. We compile a JSON Schema, a regex, a grammar, a list of function definitions or a policy into that decision, fast enough to run inside the decoding loop. This is how .txt builds reliable and safe agents. We're looking for a Rust developer to own the part of it that has to be fast: the automata, indexes and parsers that run at every decoding step. You'd turn what the rest of the team writes into production-ready Rust, with the Python bindings and C++/CUDA glue to put it inside an inference engine, and the benchmarks to prove it stays fast.\nWhat You Will Do\nProject Leadership: Initiate and drive the development of mission-critical Rust projects from conception through deployment.\n\nPerformance Engineering: Write and optimize parsing code with a strong emphasis on performance, supported by automated benchmarking.\n\nData Structures & Algorithms: Ability to design, implement, and readily debug formal grammars, efficient parsers, standard and non-standard automata, and general text-based indexing/search.\n\nCross-Functional Collaboration: Work with other teams to integration their work into production-ready Rust.\n\nTooling & CI/CD: Utilize advanced profiling, debugging, and continuous integration tools to maintain and enhance code quality in non-trivial and consistent ways.\n\nAbout You\nProven Rust Experience: Demonstrated ability to lead and contribute to sophisticated, collaborative Rust projects.\n\nProfessional Development Skills: A track record of developing well-tested, high-performance software.\n\nTooling Expertise: Expertise with code profiling and debugging. Experience with automated workflows in CI.\n\nMulti-language Proficiency: Ability to learn and/or work with the following technologies: CUDA, C/C++, Rust/Python bindings.\n\nA Collaborative Mindset: Excellent communication skills and a proactive approach, ideally suited for an early-stage startup culture.\n\nWhy You Should Join Us:\nThe problem matters\nEvery agent that takes real actions needs a layer that guarantees it can only do what it was asked. The parser and compiler work in this role is what enables this guarantee.\nRemote first\nWork from anywhere in the world. We communicate mostly in writing and favor occasional organic discussions over recurring large team meetings.\nCompetitive compensation and benefits\nMarket-rate salary plus stock options, health and dental insurance, and a 401(k) for US employees. We'll also get you a GPU if you don't have one.\nLocation\n.txt is a fully remote company with the majority of the team in the US and EU.\nFor this role, you must be based in the US.\nApplying\nPlease provide a 1-page resume in English.\nOnly apply to one position at a time.","description_format":"text","description_chars":3291,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Dental insurance","Professional development","Stock options"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Machine Learning","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-09-13T10:56:41Z"}],"visa":[{"country":"US","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"H-1B filings in 12 months: 1","filings_12m":1,"filings_prev_12m":1,"green_card_filings_12m":0,"median_offered_wage_usd":212500,"route":null,"cap_exempt":false,"checked_at":"2026-11-07T07:57:00+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":20,"band":"cold","label":"Long shot","p_open":1,"p_active":0.55,"p_room":0.36,"age_days":65,"expected_fill_days":40,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-11-07T05:47:08Z"},"pay":{"stated_usd_annual":210000,"is_top_pay":false},"html_url":"https://alion.io/job/dottxt-staff-rust-developer","json_url":"https://alion.io/job/dottxt-staff-rust-developer.json","meta":{"generated_at":"2026-11-07T12:36:17Z","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":14300,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":720119},"rest":"https://alion.io/mcp/rest/get_company?id=720119"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fdottxt-staff-rust-developer"},{"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%2Fdottxt-staff-rust-developer"},{"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%2Fdottxt-staff-rust-developer"},{"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/dottxt-staff-rust-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fdottxt-staff-rust-developer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":862464}},{"tool":"search_jobs","arguments":{"company":"dottxt.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":862464},"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.
