This role focuses on optical engine integration, characterization, and manufacturing readiness rather than device design. The successful candidate will work closely with photonic device designers to integrate EML transmitters, high-speed modulators, and waveguide photonic components into robust optical engine products suitable for high-volume production.\n\nKey Responsibilities\nLead Transmit Productization: Drive the end-to-end development of optical engine transmit modules, managing the transition from prototype validation to high-volume manufacturing.\nTranslate Specifications: Convert device-level capabilities into comprehensive optical engine performance specs and rigorous validation plans.\nComponent Characterization: Develop and execute characterization plans for EMLs, high-speed modulators, and photonic waveguide structures.\nEvaluate Key Metrics: Analyze critical transmitter parameters, including optical output power, extinction ratio, modulation bandwidth, and temperature dependence.\nSystem Integration: Collaborate with design teams to integrate laser sources and modulators into complete, high-performance optical engines.\nManufacturing Strategy: Establish engineering and production test flows specifically tailored for transmit module screening and validation.\nYield & Reliability Analysis: Utilize production data to pinpoint performance variations, yield detractors, and potential reliability risks.\nAutomated Data Workflows: Implement automated data analysis and reporting tools to identify root causes of transmitter performance limitations.\nCross-Functional Technical Support: Partner with packaging and sales teams to provide technical insights for product documentation and market-facing specifications.\nRequirements\nBachelor’s degree in Electrical Engineering, Photonics, Physics, or a related field.\nMaster’s or PhD in photonics and optoelectronics preferred.\n8–12+ years of experience in photonics, optical communications, or semiconductor optoelectronic product development.\nExperience with optical transmitter or optical engine products used in optical transceivers.\nProficiency in data collection and analysis using Excel is required; experience with JMP, Python, C/C++, MATLAB, LabVIEW, R, or similar tools is preferred.\nExperience with mask layout tools (e.g., KLayout, LayoutEditor) and simulation tools (e.g., Lumerical FDTD, RSoft, ZEMAX, SolidWorks) is an advantage.\nStrong analytical, problem-solving, and strategic thinking abilities with excellent communication and cross-functional collaboration skills.\n\nSkills\nJMP, Master Control, Optoelectronics, Optical Technologies, Development of Test Plans, communications performance, laser development, Optical Communications, Optical Long Haul 1600, Electronic and Electrical Engineering, MATLAB, Great communications skills, Performance Data, Module Testing, Electrical Engineering, Low Volume Manufacturing","description_format":"text","description_chars":3079,"description_truncated":false,"requirements":{"experience_years_min":8,"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":"2026-10-02T04:00:08Z"}],"visa":[],"liveness":{"score":77,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":0.9,"age_days":12,"expected_fill_days":31,"reasons":["seen:12","velocity","win:mid"],"computed_at":"2026-10-14T06:34:16Z"},"pay":{"stated_usd_annual":112500,"is_top_pay":false},"html_url":"https://alion.io/job/poet-technologies-principal-engineer-transmit","json_url":"https://alion.io/job/poet-technologies-principal-engineer-transmit.json","meta":{"generated_at":"2026-10-14T14:29:19Z","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":17850,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":2104401},"rest":"https://alion.io/mcp/rest/get_company?id=2104401"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpoet-technologies-principal-engineer-transmit"},{"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%2Fpoet-technologies-principal-engineer-transmit"},{"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%2Fpoet-technologies-principal-engineer-transmit"},{"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/poet-technologies-principal-engineer-transmit\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpoet-technologies-principal-engineer-transmit"}]}
