The successful candidate will be responsible for designing, developing, and optimizing high-precision mechanical systems and motion instruments from concept through productions.\nWhat We Provide:\nBlue Cross Blue Shield of MA PPO medical plan with HSA. \nDental and vision insurance. \nLTD & Life insurance. \nTuition Reimbursement\n12 Holiday days off\nPTO and Sick Time\n401k with a generous company match. \nAnd much more\nAbout Us:\nPI (Physik Instrumente), LP is a global leader in high-precision positioning systems. We design and manufacture world-class precision motion and automation solutions across our facilities in North America, Europe, and Asia. Our diverse product portfolio includes air bearings and air bearing stages, hexapod positioning and alignment systems, precision actuators, piezo drivers, and much more. Our customers are pioneers in cutting-edge industries and research institutions spanning photonics, semiconductors, aerospace, and life sciences.\nInnovation is at the core of our identity - we often create or build devices for applications being realized for the very first time, driving advancements that shape entire markets. Our culture is characterized by openness, transparency, and enthusiasm, fueled by a shared curiosity to tackle emerging scientific and technological challenges. If you possess an inquisitive mindset and enjoy developing solutions for first-generation problems, you will be right at home!\nKey Responsibilities:\nLead the design and development of mechanical components, subassemblies, and system architectures for high-precision motion instruments across full product development cycles.\nOwn mechanical design execution from concept through production release, including technical decision-making and design validation.\nDevelop advanced 3D CAD models, detailed engineering drawings, and complete design documentation with full adherence to precision tolerance and GD&T standards.\nPerform and lead engineering analysis including tolerance stack-ups, error budgets, and FEA (thermal, structural, and modal) to ensure system-level performance and stability.\nDesign precision mechanisms, motion systems, and opto-mechanical assemblies, including kinematic structures, flexures, and thermally stable architectures.\nDesign monolithic flexures (often via wire EDM) using CAD software and using ANSYS or SolidWorks to optimize for high resonant frequencies, thermal stability, and stress-strain limits.\nChoose the right piezoelectric materials and sizing them for optimum stiffness, blocking force, and displacement.\nDesign systems with closed-loop feedback-typically employ capacitive, strain gauge, or laser interferometer sensors-to eliminate hysteresis and creep.\nProgram and tune PID controllers or digital algorithms to ensure maximum bandwidth and minimal parasitic motion (pitch, yaw, and roll).\nLead prototype development, assembly, integration, and testing of motion systems, driving iterative design improvements based on test data.\nOversee system-level integration, alignment, and performance verification, with emphasis on accuracy, repeatability, drift, and environmental sensitivity.\nCollaborate closely with electrical, controls, manufacturing, and cross-functional teams to ensure seamless system integration and manufacturability.\nEvaluate and resolve complex engineering challenges, making independent technical decisions and trade-offs to meet product requirements.\nEnsure design intent, test results, and engineering decisions are thoroughly documented to support traceability, quality, and production readiness\nQualifications:\nBachelor’s degree in Mechanical Engineering or a closely related field (Master's degree preferred) \n5+ years of experience in mechanical design, product development, or mechatronic systems, with significant exposure to precision motion or high-performance mechanical systems. \nDemonstrated experience designing and releasing mechanical systems from concept through production in a product development environment. \nStrong proficiency with 3D CAD software (SolidWorks preferred) for complex assemblies, detailed design, and engineering documentation.\nPreferred Qualifications:\nExperience with precision manufacturing processes such as CNC machining, tight-tolerance fabrication, and assembly methods.\nFamiliarity with design control processes, PDM systems, and engineering change workflows.\nExperience working within ISO 9001 or similarly structured quality systems; familiarity with lean/5S principles.Background in manufacturing, especially high-mix, low-volume production environments.\nThe salary range for this role is $110,000-$170,000. Compensation is determined by factors including job-related skills, experience, and relevant education and training.\nPI (Physik Instrumente), LP is an Equal Employment Opportunity Employer/Protected Veterans/Individuals with Disabilities. Employment is dependent on the results of a background check. We are open to reasonable accommodation - please contact us at  for consideration.\nWe are not currently providing work authorization or sponsorship for this opportunity.","description_format":"text","description_chars":5267,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":["401k plan","Life insurance","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Motors, Drives & Motion Control","Precision Engineering"],"lifecycle":[{"event":"open","at":"2026-10-04T20:12:42Z"}],"visa":[],"liveness":{"score":52,"band":"ok","label":"Likely open","p_open":1,"p_active":0.697,"p_room":0.75,"age_days":31,"expected_fill_days":37,"reasons":["conf:1","win:late"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":170000,"is_top_pay":true},"html_url":"https://alion.io/job/physik-instrumente-senior-mechanical-engineer","json_url":"https://alion.io/job/physik-instrumente-senior-mechanical-engineer.json","meta":{"generated_at":"2026-10-18T09:55:31Z","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":14660,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":176481},"rest":"https://alion.io/mcp/rest/get_company?id=176481"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fphysik-instrumente-senior-mechanical-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%2Fphysik-instrumente-senior-mechanical-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%2Fphysik-instrumente-senior-mechanical-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/physik-instrumente-senior-mechanical-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fphysik-instrumente-senior-mechanical-engineer"}]}
