We've re-thought the entire stack in pursuit of this goal, from models to product, to create voice agents that feel like they truly understand you, respond emotionally and perform agentic tasks with frontier intelligence.\nOur team includes top-tier AI researchers, international olympiad medalists, and former founders.\nOur customers include companies that are building voice-native AI products in industries such as customer support, healthcare, and logistics. We have raised over $30M from tier 1 VCs.\nAbout the Team\nPhonic has a very talent-dense and close-knit team. We collaborate with high trust and are constantly trying to improve how we work to deliver world-class research and product. Everyone takes ownership in what they do and they aren’t afraid to dive in headfirst into new problems. Our team includes top-tier AI researchers, international olympiad medalists, and former founders and we’re fully in-person in our SF office.\nAbout The Role\nAs a Research Engineer at Phonic, you'll sit at the intersection of cutting-edge ML research and production engineering, working directly on the core systems that make Phonic's voice AI feel genuinely human. You'll design, train, and iterate on models across the voice stack (speech, audio, language, and beyond), while also building the infrastructure and tooling needed to move fast from research idea to deployed product.\nThis is a role for someone who thrives in ambiguity, moves with urgency, and takes full ownership of problems. You'll work closely with researchers and product engineers in a high trust, in-person environment in our SF office to push the frontier of what voice AI can do.\nWhat You’ll Do\nDesign, implement, and iterate on models across the voice stack from audio and speech to language and beyond\n\nBuild the training pipelines, evaluation frameworks, and tooling that let us experiment and iterate quickly\n\nTranslate research results into production-grade systems alongside our engineering team\n\nForm hypotheses, chase down interesting results, and take ownership over the problems you work on\n\nWhat You’ll Bring\nHands-on experience in ML research or research engineering, industry or PhD-level academia\n\nProficiency in Python and PyTorch (or JAX), and the ability to implement models cleanly from papers\n\nExperience running ML experiments end-to-end: data processing, training, evaluation, and iteration\n\nComfort in fast-moving, ambiguous environments - defining the problem is part of the job\n\nThe ability to clearly explain what you tried, what worked, and why\n\nNice To Have\nResearch experience in speech, audio, or language modeling (ASR, TTS, LLMs, codec models)\n\nFamiliarity with diffusion, flow matching, or autoregressive generative models\n\nExperience with distributed training, quantization, or inference optimization\n\nCompetitive programming or olympiad background\n\nBenefits\n Top-tier compensation: in order to get the best talent, we provide salary and equity that recognize your skillset\n\n Meals: free breakfast, lunch, and dinner provided in the office\n\n Healthcare: Comprehensive health, dental, and vision\n\nWe have regular off-sites and team celebrations\n\n 401(k) - Let us help you plan for the future. We’ve got you covered.","description_format":"text","description_chars":3345,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","LLM & Generative AI","Speech & Audio AI"],"lifecycle":[{"event":"open","at":"2026-09-12T22:26:32Z"}],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.209,"p_room":0.28,"age_days":204,"expected_fill_days":42,"reasons":["conf:9","win:tail","crowd:"],"computed_at":"2026-09-25T05:45:01Z"},"pay":null,"html_url":"https://alion.io/job/phonic-research-engineer","json_url":"https://alion.io/job/phonic-research-engineer.json","meta":{"generated_at":"2026-09-26T01:16:53Z","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":1238,"day_limit":5000,"remaining_today":3762,"minute_limit":60,"resets_at":"2026-09-27T00:00:00Z"}}}
