Our goal is to compress every patient's journey from the first signal of disease to optimal treatment with earlier, easier detection. Backed by Y Combinator, we are a dynamic team across bioscience, engineering, machine learning, and design, building diagnostics from the ground up.\nAbout the role\nThis role owns the measurement chain from sensor to reported result: readout electronics, signal processing, and the algorithms to turn raw sensor data into a quantitative output.\nWhat you'll do\nDefine readout architecture for sensor arrays: excitation, lock-in/demodulation, ADC selection, noise budgeting\nDevelop and validate signal processing and calibration algorithms (drift correction, temperature compensation, baseline estimation, multiplex deconvolution)\nCharacterize noise sources and set instrument specifications from assay requirements.\nImplement algorithms in firmware and/or host software with version control, unit tests, and traceability to requirements\nSpecify and execute analytical verification: precision, linearity, interference, and robustness studies per CLSI guidance\nSupport hardware V&V, design reviews, and DHF content for software and algorithm components (IEC 62304)\nRequirements\nMS or PhD in Electrical Engineering, Physics, or related field\n5+ years developing signal acquisition and processing for medical or scientific instruments, with at least one product through FDA clearance\nLow-noise analog design and mixed-signal system experience\nPython and C/C++ (or Rust)\nExperience defining and running analytical performance studies\nNice to have\nIVD or point-of-care diagnostics experience\nWhy Join Us:\nBe part of a visionary team that is set to change the way diagnostic testing is done.\nWork in a collaborative and innovative environment with leading experts across various fields.\nCompetitive salary and benefits package.\nOpportunities for professional growth and development in a fast-paced startup setting.\nMake a tangible impact on healthcare and improve patient outcomes through at-home diagnostics.\nEven if you feel like you don’t meet all of the qualifications, we encourage you to apply!\nResearch shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Cleancard, we welcome diverse perspectives and people who think rigorously and aren't afraid to challenge the status quo. Cleancard is an equal opportunity employer; we celebrate diversity and are committed to creating an inclusive environment, free from discrimination or harassment, for all employees.","description_format":"text","description_chars":2736,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Biosensors","Diagnostic Tests & IVD","Precision Medicine"],"lifecycle":[{"event":"open","at":"2026-10-27T20:57:25Z"}],"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":28,"reasons":["conf:1","win:early"],"computed_at":"2026-10-31T05:58:55Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/numen-senior-signal-processing-engineer-biosensor-readout","json_url":"https://alion.io/job/numen-senior-signal-processing-engineer-biosensor-readout.json","meta":{"generated_at":"2026-11-01T04:05:03Z","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":6315,"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":1937},"rest":"https://alion.io/mcp/rest/get_company?id=1937"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnumen-senior-signal-processing-engineer-biosensor-readout"},{"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%2Fnumen-senior-signal-processing-engineer-biosensor-readout"},{"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%2Fnumen-senior-signal-processing-engineer-biosensor-readout"},{"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/numen-senior-signal-processing-engineer-biosensor-readout\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnumen-senior-signal-processing-engineer-biosensor-readout"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3359927}},{"tool":"search_jobs","arguments":{"company":"numen.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3359927},"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.
