CNC Programmer III

Antares•Los Angeles, CA

4d•$41 - $51•Onsite

About The Position

Antares is seeking an experienced CNC Programmer to lead the development and execution of advanced machining processes for complex components. The role combines deep multi-axis programming expertise with hands-on machine operation and supports rapid iteration in an R&D or flight development environment. The successful candidate will help take parts from initial concept through stable, lights-out production. Antares develops deployable, inherently safe microreactors as part of its mission to make clean energy abundant. The position is based at the company’s 322,000-square-foot facility in Torrance, California, which includes spaces for collaboration, R&D, and production. Applicants must meet applicable U.S. Government export-control eligibility requirements: be a U.S. citizen or national, lawful permanent resident, refugee, or asylee, or be eligible to obtain the required authorizations from the U.S. Department of State.

Requirements

At least 5 years of CNC programming experience in a production or R&D environment.
Strong hands-on experience with multi-axis machining, including 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.
Must satisfy the stated U.S. Government export-control eligibility requirements or be eligible to obtain required authorizations.

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.
Advanced multi-axis machining and programming expertise.
Strong analytical and problem-solving skills.
A 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.

Responsibilities

Program, set up, and operate CNC mills and lathes across 2-axis, 3-axis, 3+1 rotary, full 5-axis, and mill/turn configurations.
Interpret engineering drawings and apply 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 software.
Determine cutting-tool strategies for CNC programs.
Generate and refine post-processed code for efficient, safe, and repeatable machining operations.
Create 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 that provide stable processes with minimal operator intervention.
Collaborate 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.
