You will take ownership of the optical discipline across the company's products, working on the full development lifecycle of optical systems. Your responsibilities will include system architecture and trade-offs, optical design, modelling and simulation, optical error budgets, integration and test, optical ground support equipment, model-to-test correlation, supplier management, and technical leadership. A Master's degree or PhD in Optics, Photonics, Physics, Optical Engineering or a related discipline is required, along with significant experience in the design, analysis, integration, and validation of complex optical systems.\nMissions\nParticiper à l'analyse au niveau système et aux compromis d'architecture, y compris les budgets de liaison et radiométriques.\nConcevoir des trains optiques et produire des prescriptions optiques complètes adaptées à la fabrication ou à l'approvisionnement.\nDiriger la transition de la conception au matériel, y compris la sélection des composants et des fournisseurs, la définition des procédures d'assemblage et d'alignement.\nProfil recherché\n* **Education:** Master’s degree, Engineering degree or PhD in Optics, Photonics, Physics, Optical Engineering or a related discipline.* **Professional Background:** Significant experience in the design, analysis, integration and validation of complex optical systems. You have ideally delivered an optical system end to end-from design and modelling through to manufactured hardware, alignment and testing.\n* **Technical Expertise:**\n* Strong command of at least one professional optical design and analysis software package: **FRED**, **Zemax OpticStudio**, **Code V** or equivalent.\n* Solid grounding in geometrical and physical optics, including beam propagation, diffraction, coupling, radiometry and polarisation.\n* Experience in non-sequential modelling, stray-light analysis, Monte Carlo tolerancing and the definition of realistic compensators.\n* Experience in optical prescription writing, thin-film and coating specification, as well as manufacturing tolerances.\n* Programming and scripted-analysis skills, particularly in **Python**; familiarity with Mathematica is a plus.\n* Good command of optical metrology techniques, including interferometry, wavefront sensing, autocollimation, beam profiling, power measurement and spectral measurement.\n* **System Engineering Mindset:** You are comfortable building and owning error budgets, justifying requirements and making technical trade-offs at the interface of optics, mechanics, thermal engineering, electronics and industrial constraints.\n* **Relevant Industry Experience:** Experience in space systems, precision instrumentation, photonics, optical communications, defence electro-optics or similarly demanding environments would be highly valued.\n* **Mindset:** You are motivated by technical ownership and able to lead a discipline, challenge technical decisions constructively and make sound engineering judgements. You are equally comfortable developing models and working hands-on in the lab, translating measurement results into engineering decisions.\n* **English:** Professional working proficiency in English, with the ability to write technical documentation and communicate effectively with international suppliers and partners.","description_format":"text","description_chars":3365,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Upper-Intermediate (B2)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-07T13:18:26Z"}],"visa":[],"liveness":{"score":75,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.832,"p_room":0.9,"age_days":36,"expected_fill_days":61,"reasons":["conf:3","velocity","win:mid","comp:brand"],"computed_at":"2026-10-28T05:59:10Z"},"pay":{"stated_usd_annual":67516,"is_top_pay":false},"html_url":"https://alion.io/job/exalt-company-lead-optical-systems-engineer","json_url":"https://alion.io/job/exalt-company-lead-optical-systems-engineer.json","meta":{"generated_at":"2026-10-28T22:11:04Z","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":29963,"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":1953957},"rest":"https://alion.io/mcp/rest/get_company?id=1953957"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fexalt-company-lead-optical-systems-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%2Fexalt-company-lead-optical-systems-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%2Fexalt-company-lead-optical-systems-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/exalt-company-lead-optical-systems-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fexalt-company-lead-optical-systems-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":2020243}},{"tool":"search_jobs","arguments":{"company":"exalt-company.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":2020243},"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.
