This role works on the pipeline that turns order-book records into validated models, next to more experienced engineers: data preparation, experiments end to end, and the checks that keep the future out of a training set.\nFully remote, from anywhere in the world. Junior.\nBase salary: USD 125,000-155,000 a year.\nTo apply: a link to your résumé, LinkedIn or GitHub, and one sentence on any of our articles.

One market and one horizon at a time, and every measurement written up with its sample and its limits.\nContact Info\nContact: HFT Architecture\nE-mail contact: \nWeb: https://hftarchitecture.com/careers/junior-machine-learning-engineer?utm_source=pythonorg&utm_medium=jobboard&utm_campaign=careers-2026-10","description_format":"text","description_chars":1548,"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":"2026-10-26T20:07:15Z"}],"visa":[],"liveness":{"score":62,"band":"ok","label":"Likely open","p_open":0.85,"p_active":0.811,"p_room":0.9,"age_days":14,"expected_fill_days":25,"reasons":["seen:14","win:mid","comp:remote,junior"],"computed_at":"2026-10-28T05:59:10Z"},"pay":{"stated_usd_annual":155000,"is_top_pay":false},"html_url":"https://alion.io/job/hft-architecture-junior-machine-learning-engineer","json_url":"https://alion.io/job/hft-architecture-junior-machine-learning-engineer.json","meta":{"generated_at":"2026-10-28T23:04:24Z","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":31519,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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":4433997},"rest":"https://alion.io/mcp/rest/get_company?id=4433997"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhft-architecture-junior-machine-learning-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%2Fhft-architecture-junior-machine-learning-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%2Fhft-architecture-junior-machine-learning-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/hft-architecture-junior-machine-learning-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhft-architecture-junior-machine-learning-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3291267}},{"tool":"search_jobs","arguments":{"company":"hftarchitecture.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3291267},"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.
