The role sets design direction and standards, owns the reference architectures others build on, and coordinates internal specialists and third parties on the hardest technical questions. It leads through technical authority rather than people management, and it is not the primary customer interface: it brings the deep dive when Technical Sales opens the door. The Principal AE holds final technical authority on product configuration and on the non-standard or architectural questions escalated by Application Engineering and Pre-Sales Engineering.\nRole scope\nDomain technical authority for one of Critical Power Systems (UPS, batteries, AI load, grid), Power Distribution & Integration (MV, LV, busway) or Engineered Solutions (Power SKID, ETO, modular): reference architectures, design standards, senior review, mentoring and third-party coordination.\nKey accountabilities\nOwn the reference architectures and design rules for the domain, and keep them current as the technology moves.\nOwn simulation and digital-twin based design validation for the domain, using it to prove architectures before they are committed.\nAct as senior technical reviewer and escalation point for the most complex designs and non-standard solutions raised by Application Engineering and Pre-Sales Engineering (including MV switchgear), with an agreed turnaround so that escalations do not become a bottleneck.\nBring deep-dive technical expertise to consultant engagements and strategic pursuits led by Technical Sales.\nCoordinate internal specialists and third parties on complex solutions, holding the technical thread across them.\nGovern the engineering library for the domain: decide what enters it, approve deviations raised through the CDE route, and enforce reuse so that solutions are configured rather than redesigned - working with Product Management and the Global Business Units, which co-own the building blocks.\nOwn technical training and certification of Application Engineers, Technical Sales and partners in the domain, including system-level thinking - turning expertise into scalable capability rather than a personal dependency.\nMentor and develop engineers across disciplines, raising the technical bar of the wider team.\nTrain Application Engineers and Technical Sales in system-level thinking for the domain. \nWork with Product Management and factory engineering on product gaps, roadmap input and new technology introduction.\nSupport the Power System Lead on architectural questions and the introduction of emerging technologies.\nBuild the emerging capabilities of the domain - for Critical Power Systems, grid interaction (power simulation, power smoothing, BESS and Microgrid design); for Engineered Solutions, Power SKID sub-assemblies - engaging ETO and Global Engineering early.\nProvide the validated design rules, technical knowledge and data behind CPQ rules, configurators and AI-enabled engineering tools for the domain, and check that their outputs are technically sound.\nConvert lessons learned and technical decisions from complex projects into reusable standards, training and engineering assets.\nWorking model and level expectations\n\nCustomer engagement\n\nSelective and deep: technical deep dives, design workshops, consultant sessions - not the primary interface.\n\nTravel expectation\n\nLow to moderate; travel for complex pursuits, design workshops and training.\n\nTypical work\n\nReference architectures, design standards, senior review, complex solution support, mentoring.\n\nDecision profile\n\nSets technical direction for the domain; final technical say on design standards, non-standard configurations and approved deviations.\n\nLeadership expectation\n\nLeads through technical authority; no people management responsibility.\n\nRole differentiators\nTechnical authority for a domain, not a people manager.\nOwns reference architectures and design standards rather than individual opportunities.\nSupports customer engagements with depth; Technical Sales owns the relationship.\nQualifications and experience\nBachelor's or Master's degree in engineering, or equivalent practical experience.\nMinimum 12 years of experience in application engineering, design engineering or power systems.\nDeep expertise in the domain, with strong working knowledge of the wider power train - UPS and large power converters, power distribution, LV and MV switchgear, busway, energy storage, DC power and power skids.\nCredible on the emerging technologies: BESS, microgrid and grid interaction, 800V DC architectures, and power software and controls.\nDepending on the domain, deep expertise in MV (up to 36kV) and LV distribution, switchgear, busbar systems, transformers, UPS, STS/PDU, RPP, protection and automation, power quality, harmonics, grounding and Tier III/IV reliability concepts, with command of network calculation, simulation and digital-twin tooling, and of IEC, IEEE and EMEA national codes.\nProven ability to set standards and raise the capability of others.\nStrong written and verbal English; additional EMEA languages an advantage.\nCore competencies\n\nDeep technical authority\n\nDesign standards and reuse\n\nMentoring and capability building\n\nComplex problem solving\n\nThird-party coordination\n\nClear technical communication\n\nJudgement under ambiguity\n\nInfluence without authority\n\nIndicative success measures\nAccurate, complete and timely technical inputs to opportunities, projects and customer discussions. \nPositive feedback from Sales, customers and internal stakeholders on clarity, responsiveness and technical quality. \nEffective use of approved systems, tools and processes, with clear documentation and handover quality. \nVisible contribution to knowledge sharing, risk identification and solution improvement appropriate to the level. \nCapability built: engineers trained and certified in the domain\nThis role may be performed in multiple jurisdictions. In jurisdictions subject to EU Pay Transparency requirements, a locally applicable salary range applies and will be communicated in accordance with local legal obligations, if not shown in this posting. Salary ranges for other jurisdictions may vary in line with local market conditions and applicable legislation.","description_format":"text","description_chars":6334,"description_truncated":false,"requirements":{"experience_years_min":12,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Servers & Data Center Hardware","Power Supplies & Power Electronics","HVAC & Refrigeration"],"lifecycle":[{"event":"open","at":"2026-11-03T14:36:21Z"}],"visa":[{"country":"IE","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"Irish employment permits in 12 months: 1","filings_12m":1,"filings_prev_12m":0,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Employment permits","cap_exempt":false,"checked_at":"2026-11-07T07:57:00+00:00","sources":["Department of Enterprise, Trade and Employment: employment permits issued to companies"],"filings_for_role_12m":0}],"liveness":{"score":62,"band":"ok","label":"Likely open","p_open":1,"p_active":0.624,"p_room":1,"age_days":3,"expected_fill_days":14,"reasons":["conf:0","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/vertiv-principal-application-engineer","json_url":"https://alion.io/job/vertiv-principal-application-engineer.json","meta":{"generated_at":"2026-11-07T08:00:33Z","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":3893,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":58885},"rest":"https://alion.io/mcp/rest/get_company?id=58885"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvertiv-principal-application-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%2Fvertiv-principal-application-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%2Fvertiv-principal-application-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/vertiv-principal-application-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvertiv-principal-application-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3684985}},{"tool":"search_jobs","arguments":{"company":"vertiv.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3684985},"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.
