Founded in 2018 and backed by leading venture capital, we’ve built a team and a platform focused on real-world mass deployment of TFLN photonics technology.\nAt the core of our work is the TFLN Chiplet™ platform - a modular, integrated architecture designed for scalability, manufacturability, and seamless integration into complex systems. It offers a rare combination of extraordinary performance and industrial readiness, enabling system developers across applications to deploy the technology fast and ready. We partner with our customers and suppliers from conceptualization, design, and prototyping phases, all the way through mass production to ensure smooth and rapid deployment of TFLN photonic technology.\nWe believe our platform is the key, in the golden age of integrated photonics, to empower humanity to the next level. We assembled a world class team covering engineering, business, and operations. We believe in the power of integrity, innovation, collaboration, and pragmatic solutions. Our diverse team thrives on challenges and is united by a shared commitment to excellence. We take pride in tackling complex challenges with curiosity, humility, and a deep sense of care for one another.\nOur growing team is looking for a hands-on Transceiver R&D Engineer to own the design, characterization, and qualification of advanced optical transceiver reference designs. You'll work across firmware, DSP, optics, and hardware to ensure our QSFP/OSFP-based transceivers meet performance and interoperability requirements.\nAs part of your responsibilities, you will be:\nDefine and execute test plans for optical transceivers (IMDD and/or coherent)\nCharacterize transceiver performance for >1.6T modules - BER, eye diagrams, SNR, OSNR, TDECQ, OER, OMA, receiver sensitivity, latency, and more\nValidate TFLN modulator-based transceivers across electrical, optical, and thermal domains\nBring up and debug QSFP/OSFP transceiver modules\nCollaborate with firmware and DSP teams to tune system performance\nSupport compliance testing (IEEE, OIF, CMIS)\nAnalyze failures, drive root-cause resolution, and recommend design improvements\nRequirements\nBachelor's or Master's degree in Electrical Engineering, Physics, or a related field\n5 to 12+ years of relevant experience in high-speed optical transceiver testing and/or design (>400 Gbps)\nExperience with Datacom and/or Telecom transceivers\nHands-on experience with QSFP and OSFP form factors\nSolid understanding of PAM4, TDECQ, BER, OSNR, jitter, eye diagrams, and receiver sensitivity\nProficiency with lab equipment - oscilloscope, DCA, BERT, OSA, VNA, etc.\nStrong debugging skills and a methodical approach to troubleshooting\nClear communicator, able to articulate issues and solutions across teams\nPreferred Qualifications\nExperience with TFLN, silicon photonics, or other advanced modulator technologies\nFamiliarity with PAM4, coherent detection, and DSP-based systems\nExperience with thermal and reliability testing\nExperience building semi-automated test systems\nFamiliarity with the OSFP/QSFP MSA specifications\nKey Skills\nCircuit design & characterization\nSignal integrity (electrical + optical)\nDebugging & product bring-up\nData analysis\nCross-functional collaboration\nWhat Success Looks Like\nTransceivers brought up and validated to meet spec under real-world conditions\nIssues identified and resolved early, with clear root-cause analysis and improvement plans\nCustomers empowered to optimize performance on our modules\nMeasurable performance gains delivered for 1.6T+ systems\nBenefits\nCompetitive market-based compensation and benefits\nProfessional growth and mentorship opportunities","description_format":"text","description_chars":3953,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Optical Communications","Optics & Photonic Components"],"lifecycle":[{"event":"open","at":"2026-09-07T01:34:41Z"}],"visa":[],"liveness":{"score":60,"band":"ok","label":"Likely open","p_open":1,"p_active":0.837,"p_room":0.72,"age_days":110,"expected_fill_days":168,"reasons":["conf:0","win:mid","crowd:"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/hyperlight-senior-optical-transceiver-rd-engineer","json_url":"https://alion.io/job/hyperlight-senior-optical-transceiver-rd-engineer.json","meta":{"generated_at":"2026-11-01T19:31:06Z","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":29921,"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":3370},"rest":"https://alion.io/mcp/rest/get_company?id=3370"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhyperlight-senior-optical-transceiver-rd-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%2Fhyperlight-senior-optical-transceiver-rd-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%2Fhyperlight-senior-optical-transceiver-rd-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/hyperlight-senior-optical-transceiver-rd-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhyperlight-senior-optical-transceiver-rd-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":491857}},{"tool":"search_jobs","arguments":{"company":"hyperlightcorp.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":491857},"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.
