From individual chemical samples, it pieces together connections between cases and helps tell whether seemingly unrelated cases are in fact linked. Our data comes from Catcher, our own portable device built on patented UV-Fingerprint technology, which creates a unique profile of an unknown sample within minutes, right in the field. Every measurement feeds a shared database, so we don’t just say what’s in a sample, we can tell where we’ve seen something like it before and what it might connect to. We work with law-enforcement agencies in the Czech Republic, the EU and the U.S.\nAbout the role\nYou will own the path from a measured sample to an answer you can trust: the evaluation algorithms, the quality of the data behind them, and the design of the measurements themselves. Most of the problems you’ll face haven’t been solved before, so solid mathematics and statistics are a must. And we’re a startup: one week you’re tuning a model, the next you’re planning a customer pilot or measuring samples in the lab yourself.\n\nWhat you’ll do\nDevelop and benchmark methods for evaluating spectral data\n\nKeep our measurement database clean and our experiments reproducible\n\nDesign measurement campaigns and pilots, evaluate them and report clearly\n\nMeasure substances yourself from time to time, both in the lab and at partner sites\n\nWho we’re looking for\nA strong foundation in mathematics or physics\n\nAt least 2 years of experience working with data, machine learning or research (a PhD counts)\n\nStrong Python and practical SQL\n\nExperimental design and honest validation\n\nWillingness to travel in Czechia and abroad; fluent English\n\nNice to have\nSignal processing, spectroscopy or chemometrics, lab experience, driving licence (cat. B).\n\nWhat we offer\nReal data from our own instruments, not public datasets\n\nWork with real impact: what you come up with decides what the device recognises in the field\n\nThe whole chain, from measurement to deployment, in one role\n\nA small team, short decision paths and work with law-enforcement agencies\n\nHow to apply\nSend your CV and a few sentences about a project with real (and messy) data.","description_format":"text","description_chars":2223,"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":["Computer Vision","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-10-27T14:40:55Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":3,"expected_fill_days":39,"reasons":["seen:3","win:early"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/lightly-data-scientist","json_url":"https://alion.io/job/lightly-data-scientist.json","meta":{"generated_at":"2026-11-01T04:17:54Z","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":6616,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":679232},"rest":"https://alion.io/mcp/rest/get_company?id=679232"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flightly-data-scientist"},{"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%2Flightly-data-scientist"},{"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%2Flightly-data-scientist"},{"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/lightly-data-scientist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flightly-data-scientist"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3338550}},{"tool":"search_jobs","arguments":{"company":"lightly.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3338550},"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.
