You will own problems end-to-end, from shaping model behavior, to building the systems around it, to ensuring it performs reliably in production. This role sits at the intersection of machine learning, systems, and product, focusing on making AI actually work for users, not just in demos, but in real-world usage. Sounds great - what will I do? Build and ship AI features end-to-end (model, system,user experience) Design and iterate on prompts, tools, memory, and agent workflows \u0002 Turn raw model outputs into structured, reliable, and predictable behaviors \u0002 Debug issues across the full stack (model, orchestration, infra, UX) \u0002 Optimize for latency, cost, and production reliability \u0002 Develop lightweight evaluation frameworks to measure real-world performance \u0002 Work closely with product and engineering to translate ambiguous problems into working systems\nWhat you'll bring\nTech Stack \u0002 Python \u0002 PyTorch / JAX \u0002 LLMs (OpenAI-style APIs, LLaMA, Qwen, etc.) \u0002 Inference / serving (e.g. vLLM) Vector DB Ideal Experience \u0002 Strong foundation in machine learning and modern neural network architectures. \u0002 Hands-on experience with training, fine-tuning, or deploying ML models \u0002 Ability to write clean, production-quality code \u0002 Comfort working across abstraction layers (model, infra, product) \u0002 Strong problem-solving skills in ambiguous, fast-moving environments \u0002 Bias toward shipping, iteration, and continuous improvement","description_format":"text","description_chars":1531,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-26T02:34:11Z"}],"liveness":{"score":40,"band":"fade","label":"Fading","p_open":1,"p_active":0.448,"p_room":0.9,"age_days":10,"expected_fill_days":21,"reasons":["conf:10","agency","velocity","win:mid"],"computed_at":"2026-09-27T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/hackertrail-applied-ai-engineer","json_url":"https://alion.io/job/hackertrail-applied-ai-engineer.json","meta":{"generated_at":"2026-09-28T03:21:59Z","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":2104,"day_limit":5000,"remaining_today":2896,"minute_limit":60,"resets_at":"2026-09-29T00:00:00Z"}}}
