CNC Programmer / Machinist

At 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 mission

We 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 components

• Machine 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 mills

• Haas UMC-750 5-axis mills

• Design 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 effectiveness

• Utilize 

  Renishaw probing systems

   (tool setter and part probe) for setup, in-process verification, and inspection

• Support 

  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 intent

• Perform first-article inspections and support quality documentation

• Work closely with manufacturing and design engineers to influence DFM and process development

• Help establish shop best practices, standard work, and workflows as the shop grows

Safety, Organization & Culture

• Maintain an 

  extremely high standard of safety

   — safety is the number one priority

• Take ownership of equipment care, preventive maintenance, and proper machine use

• Keep tooling, fixtures, and work areas organized and clearly labeled

• Support and help build a 

  5S / Lean manufacturing environment

• Demonstrate a proactive, can-do attitude and willingness to step in where needed

Skills & Requirements:

You'll Bring These Qualifications for CNC Programmer/Machinist

• 5+ years of experience

   as a CNC Programmer/Machinist in aerospace or high-precision manufacturing

• Significant experience machining 

  large aluminum structural components

• Strong proficiency with 

  Autodesk Fusion CAM

• High level of skill operating 

  Haas VF-series 3-axis

   and 

  Haas 5-axis

   mills

• Hands-on experience with 

  Renishaw tool and part probing

• Experience designing fixtures and executing full machine setups

• Solid understanding of 

  GD&T, datum structuring, and inspection techniques

• Experience with manual mill and lathe operations

• Ability to work independently and make sound machining and process decisions

These Qualifications Would Be Nice to Have:

• Aerospace manufacturing experience

• Experience supporting both prototype and low-rate production environments

• Familiarity with scaling machining processes toward higher-rate production

• Experience establishing or growing a machine shop function

Why This Role

• Be the 

  first machinist hire

   and help shape the future of the machine shop

• Work directly on a first-of-its-kind 

  hybrid-electric aircraft program

• High level of ownership, autonomy, and technical influence

• Collaborative, engineering-driven environment
