CNC Programmer/MachinistLos Angeles, CAAt Heart Aerospace we develop the ES-30, a regional hybrid-electric airplane with a capacity of 30 passengers, an electric zero-emission range of 200 km and an extended hybrid range of 400 km. Heart is targeting type certification of the ES-30 by the end of the decade.Your missionWe are building hybrid-electric aircrafts and are establishing an in-house machine shop to support prototype, tooling, and early production efforts. We are seeking a CNC Programmer/Machinist who will be the first hire in the machine shop.
You will have an opportunity to play a key role in shaping machining processes, standards, and culture.This is a hands-on role requiring deep experience machining large aluminum structural components, developing robust processes, and transitioning work from prototype through low-rate production. The ideal candidate brings strong technical judgment, takes pride in craftsmanship, and operates with an unwavering commitment to safety and equipment care.Key responsibilities include but are not limited to:Program, set up, and operate CNC machines for prototype, tooling, and low-rate production componentsMachine components of various materials (Alum, SS, Steels, Ti) of varying heat treatments. Main categories include large aluminum structural parts, battery and electrical housing development components, and miscellaneous test tooling components.Develop CNC programs using Autodesk Fusion (CAM)Operate and support:Haas VF-4 3-axis millsHaas UMC-750 5-axis millsDesign and build fixtures and work holding, and perform complete machine setups.Complete machining operations through first article inspection.Develop tool lists and machining strategies that prioritize safety, accuracy, surface quality, and cost effectivenessUtilize Renishaw probing systems (tool setter and part probe) for setup, in-process verification, and inspectionSupport manual mill and lathe work for quick-turn prototype parts, tooling, and fixturing.Perform saw operations to prepare raw material as required and perform final deburr including edge-breaks, polish and thread work as required.Apply strong understanding of GD&T, datum structures, and inspection methods to ensure parts meet engineering intentPerform first-article inspections and support quality documentationWork closely with manufacturing and design engineers to influence DFM and process developmentHelp establish shop best practices, standard work, and workflows as the shop growsSafety, Organization & CultureMaintain an extremely high standard of safety — safety is the number one priorityTake ownership of equipment care, preventive maintenance, and proper machine useKeep tooling, fixtures, and work areas organized and clearly labeledSupport and help build a 5S / Lean manufacturing environmentDemonstrate a proactive, can-do attitude and willingness to step in where neededSkills & Requirements:You'll Bring These Qualifications for CNC Programmer/Machinist5+ years of experience as a CNC Programmer/Machinist in aerospace or high-precision manufacturingSignificant experience machining large aluminum structural componentsStrong proficiency with Autodesk Fusion CAMHigh level of skill operating Haas VF-series 3-axis and Haas 5-axis millsHands-on experience with Renishaw tool and part probingExperience designing fixtures and executing full machine setupsSolid understanding of GD&T, datum structuring, and inspection techniquesExperience with manual mill and lathe operationsAbility to work independently and make sound machining and process decisionsThese Qualifications Would Be Nice to Have:Aerospace manufacturing experienceExperience supporting both prototype and low-rate production environmentsFamiliarity with scaling machining processes toward higher-rate productionExperience establishing or growing a machine shop functionWhy This RoleBe the first machinist hire and help shape the future of the machine shopWork directly on a first-of-its-kind hybrid-electric aircraft programHigh level of ownership, autonomy, and technical influenceCollaborative, engineering-driven environmentPay Range: $40/HR — $56/HR (USD)
