We believe that credible deterrence of armed conflict and winning if deterrence fails, requires more than just the best drones, sensors, weapons, electronic warfare systems, and command & control capabilities. Those critical components will require sustained electric power in austere and resource-constrained environments. Moreover, military units must be able to turn off the trucks and generators that generate this power to hide and survive. In other words, power generation must be decoupled from power consumption. Chariot Defense’s products enable exactly this capability, allowing U.S. and allied militaries to be more lethal and survivable. We hope you will join us on this mission.\nAbout the Role \nChariot Defense is seeking a highly motivated and skilled Mechanical Engineer to join our engineering team, reporting to the Powertrain Lead Engineer. In this role, you will conceptualize, design, develop, and test advanced mechanical and power electronic systems, including fully integrated vehicle platforms. You will work across multidisciplinary engineering and design teams to ensure our systems meet stringent MIL-STD performance, endurance and reliability, and security requirements for deployment in demanding environments, performing critical missions. \nKey Responsibilities \nDesign Ownership: Own hardware design from initial requirements to concept and prototyping to series production, and beyond, in service and field deployment, as an end-to-end owner of subsystems.\nIntegrated Systems: Develop mechanical designs that involve the complex and multivariable mechanical integration of next-gen energy storage, advanced material types, complex thermal solutions, power electronic hardware, dense PCBAs, and efficient harnessing for the tightest packaged, most efficient, and highest performing end-product. \nRapid Iteration: Prototype rapidly to find issues fast, debug, iterate, and develop a final, field-deployable product on compressed timelines, closely managing risk vs. reward, effort vs. return, and balancing schedules and budget with capability and performance.\nDesign for Mass Manufacturing: Design mechanical, thermal, electro-mechanical components and assemblies, and integrated power systems, for volume manufacturing from the get-go. \nDirect Customer Engagement: Support critical customer-facing hardware demonstrations, from time to time, and use these interactions to better understand the customers’ requirements and application needs.\nWhat We’reLooking For \nTop-notch engineering intuition and first principles thinking toward designing complex products that function seamlessly for your customer, taking both an engineering/ technical, and product/ customer approach, to strike the optimal balance.\nAble to independently identify critical information or priority gaps and apply effort toward closing those gaps.\nUndaunted by imperfect, incomplete or absent datasets or information, and capable of making sound, comprehensive, and swift first-principled decisions to achieve a product end-state that meets and/or exceeds the need of the hour.\nNot satisfied by superficial explanations of a problem or “band-aid engineering”; seeks persistently to find the specific root cause through data-driven methods, and resolve failures or recurring issues, so they can be mitigated to prevent future such instances.\nGratified by helping your peers succeed, building a robust team culture, and propagation deep camaraderie amongst your peers; seeks to break down information silos by collaborating rigorously with others to solve problems, share knowledge, and provide input.\nQualifications \nRequired: \nBS or MS in Mechanical Engineering, or equivalent work experience.\nExperience in an immersive system design project or research study/ thesis, in collegiate project teams (e.g.: SAE, FSAE, BAJA, others), other extracurricular participation, or professional settings.\nA minimum of 2+ years of experience in a technical engineering, design, or product role in a professional setting.\nProven 3D CAD skills (any platform, but SOLIDWORKS preferred), as well as CAE/ FEA experience, and the ability to produce high-quality engineering 2D drawings that comply with common industry standards (e.g.: GD&T, ASME standards etc.)\nStrong understanding of engineering fundamentals in structures, materials, fluids and aero, thermal, controls, mechanics/ dynamics, system modeling, and fundamentals of physics.\nManufacturing knowledge & experience with machine shops (sheet metal, CNC, lathe, sand casting, forging, die-casting etc.).\nRapid prototyping background (structures/electronics/software) & 3D printing knowledge.\nProficient in hands-on prototyping (machining, shop tools, welding, soldering), and demonstrated hands-on fabrication skills.\nFamiliarity with MIL-STD, DO-160, or other automotive, defense, and aerospace standards.\nPreferred: \nExperience designing and working directly with low and high voltage systems, high current/ high voltage power distribution, high voltage safety, and thermal management of lithium-ion batteries (or other energy storage) and voltage regulating power electronics.\nExperience in industries/ applications requiring high-reliability embedded power electronics operated in austere environments, and testing exposure for lifecycle, abuse, and endurance tests.\nMATLAB/ SIMULINK/ SIMSCAPE experience, as well as experience with any or several CAE/ FEA tools such as ANSYS, Fluent, Star CCM+, Abaqus, Comsol Multiphysics, Hyperworks etc.\nExperience with any or several instrumentation, scripting, communication and measurement tools such as LabVIEW, DIAdem, DAQs, PEAK (PCAN), Vector (CANape, CANoe etc.), Python.\nExperience with any or several data, content, and product lifecycle management systems like Confluence, JIRA, Polarion, Tableau, Teamcenter etc.\nExperience with any or several common sensors and sensing methods (such as thermocouples, force/ load sensors, flow sensors, voltage probes, current clamps etc.), sensor integration, and sensor data post processing/ filtering.\nAdvanced designing skills for CNC machining, composites/ CFRPs, sheet metal, injection molding, PCBA integration.\nRole Requirements\nThis position is an onsite role based in Chariot Defense’s San Bruno, CA, office. \nWillingness to support 10% travel, domestically and internationally, as well as work extended and weekend hours, when necessary \nAble to work on your feet for extended periods in a shop setting. \nAble to lift and carry 50lbs. \nA reasonable estimate of the current salary range is $130,000-$180,000 annually. Compensation packages also include early-stage equity and access to company-sponsored benefit plans.\nIndividual compensation packages are based on geographic location, scope of the role, relevant experience, and the ability to deal with complexity and problem solve within our organization, among other factors. \nAll employees are required to provide proof of authorization to work in the U.S. within their first 3 days of work. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status. \nAny unsolicited resumes/candidate profiles submitted through our website or to personal email accounts of employees of Chariot Defense are considered property of Chariot Defense and are not subject to payment of agency fees.","description_format":"text","description_chars":7536,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Defense Manufacturing","Defense AI"],"lifecycle":[{"event":"open","at":"2026-09-13T07:41:52Z"}],"visa":[{"country":"US","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"H-1B filings in 12 months: 1","filings_12m":1,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":377500,"route":null,"cap_exempt":false,"checked_at":"2026-11-09T07:32:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.091,"p_room":0.28,"age_days":214,"expected_fill_days":29,"reasons":["conf:1","stale_co","ghost","win:tail","crowd:junior"],"computed_at":"2026-11-09T06:03:00Z"},"pay":{"stated_usd_annual":180000,"is_top_pay":true},"html_url":"https://alion.io/job/chariotdefense-mechanical-engineer","json_url":"https://alion.io/job/chariotdefense-mechanical-engineer.json","meta":{"generated_at":"2026-11-10T06:24:55Z","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":14928,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-11T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":673748},"rest":"https://alion.io/mcp/rest/get_company?id=673748"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fchariotdefense-mechanical-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fchariotdefense-mechanical-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fchariotdefense-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/chariotdefense-mechanical-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fchariotdefense-mechanical-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":857722}},{"tool":"search_jobs","arguments":{"company":"chariotdefense.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":857722},"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.
