Senior CNC Programmer

Senior CNC Programmer

We are looking for an experienced Senior CNC Programmer to lead the development and execution of advanced machining processes for complex components. This role requires deep expertise in multi-axis programming and hands-on operation, along with the ability to support rapid iteration in a fast-paced R&D or flight development environment. The ideal candidate is highly technical, detail-oriented, and capable of driving parts from initial concept through stable, lights-out production.

Roles and Responsibilities:

• Program, set up, and operate CNC mills and lathes across multiple configurations, including 2-axis, 3-axis, 3+1 rotary, full 5-axis, and mill/turn platforms
• Interpret engineering drawings, applying GD&T principles and tolerance stack-up analysis to ensure part conformity
• Develop, optimize, and troubleshoot CNC programs using CAM software such as Esprit, or similar
• Determine cutting tool strategies for CNC programs
• Generate and refine post-processed code to ensure efficient, safe, and repeatable machining operations
• Create comprehensive setup sheets, tooling lists, and standardized work instructions for repeatable manufacturing
• Lead machining process development from first article through full production readiness
• Design and implement lights-out machining strategies, ensuring process stability and minimal operator intervention
• Collaborate closely with design, manufacturing, and quality teams to resolve technical challenges and improve manufacturability
• Identify and implement cycle time reductions, tooling improvements, and cost-saving opportunities
• Support rapid prototyping and iterative development in an agile, high-mix/low-volume environment

Basic Qualifications:

• 5+ years of CNC programming experience in a production or R&D environment
• Strong hands-on experience with multi-axis machining (2-axis, 3-axis, 3+1 rotary, 5-axis, and mill/turn)
• Proficiency with CAM software such as Esprit, or equivalent
• Experience running lights-out production environments
• Demonstrated ability to transition parts from first article to full production
• Strong understanding of GD&T and tolerance stack-up analysis
• Experience creating detailed setup documentation and process instructions

Preferred Qualifications:

• Experience in a startup or agile development environment
• Experience with Fanuc CNC controllers
• Experience in an AS9100 (or similar) machining environment
• Experience in fast-paced R&D or prototype-driven manufacturing environments
• Familiarity with high-precision, tight-tolerance components
• Experience machining high strength metallics, superalloys, and/or graphite

Key Competencies:

• Advanced multi-axis machining and programming expertise
• Strong analytical and problem-solving skills
• Process optimization and continuous improvement mindset
• High attention to detail and commitment to quality
• Ability to manage multiple priorities in a fast-paced environment
• Effective cross-functional communication and collaboration

Location:

• We are located in Torrance, CA in a 322,000 square foot, brand new facility featuring large open spaces for team collaboration, R&D, and production, as well as easy access to the 405, 105, and 110 freeways. Our facility is in the heart of Los Angeles' vibrant emerging tech ecosystem alongside many other high growth startups and enterprises.

Culture:

• Think in Systems - Energy and Defense are complex ecosystems with numerous stakeholders with competing priorities, conflicting policies, perverse incentives, and emergent and path-dependent properties. First principles thinking alone is insufficient. Think probabilistically and then take action. "If you want to be certain, then you are apt to be obsolete." Over-optimizing the components often degrades the system
• Obsess over the End User - The customer and end user are often not the same. We will never build globally competitive commercial products if we lose sight of our end users and their entire interaction with the product life cycle
• Be Unconstrained by Convention - Our only limits are the laws of physics. Many, even experts, will say what we are working on is impossible. They said the same about SpaceX reusing rockets. Generationally impactful companies, by definition, must accomplish the seemingly impossible. If it were easy, it would have already been done. Never shy away from a solution because it has never been tried before, and never choose to do something because that's "how it's always been done"
• Go Where the Work Is - Never miss a chance to meet a customer, user, or stakeholder face to face, even if that means hopping on a plane. If you can't make it, find a teammate who can channel your intentions and go in your place. Deep work can be done from anywhere, but we believe teams are built in person, and aim to maximize our time together
• Operate in the Grey - Embrace nuance in pursuit of truth. Question every fundamental assumption
