Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
The Lead Machinist will program and operate 5-axis CNC machines to manufacture prototypes and small batch production parts. They will also manage other CNC operators, maintain machine tools, and perform CMM inspections.
Candidates must have at least 5 years of 5-axis programming and operating experience with strong G-Code and CMM skills. Proficiency in parametric CAD software like Solidworks or Fusion is required.
Rainmaker is pioneering a modern cloud seeding system to solve water scarcity and inclement weather problems. We develop and incorporate radar validation, weather-resistant UAS, numerical weather modeling, and sustainable cloud seeds into an effective precipitation enhancement solution.
The Production team at Rainmaker builds our UAS platforms, assembles dispersion payloads, and integrates in-situ/remote sensing systems into every vehicle we deliver. If you are interested in working in an extremely innovative and fast-paced environment, where your work directly makes an impact and ensures mission success in the field, this is a fantastic opportunity.To meet our engineering, test, and production goals Rainmaker requires the ability to manufacture its own machined parts in timelines not possible by outsourcing. Our solution is to bring our own full spectrum prototyping and small batch production capabilities in house. We continue to build out our internal toolset with the most recent addition of a 2026 Haas UMC 500ss, Mitutoyo Mistar 575 cmm, Shunk workholding, and Haimer tool presetter / shrink station / Balancer. To complement this, we are seeking someone to fill the role of Lead 5 Axis Machinist.
\nWhat You'll DoReceiving parts and drawings from engineers. Reviewing them to provide feedback for manufacturability.
Program toolpaths for these parts in your CAM platform of choice.
Set up and run 5 axis jobs you programmed.
Maintain a tool and workholding library that can support both highly varied prototypes as well as stable short run production.
Manage the maintenance and calibrations of our machine tools.
Program and operate CMM inspection as well as provide results to engineers.
Manage other CNC operators and machinists.
Not be afraid to get dirty, make cool parts day in and out, help bring an end to fresh water scarcity.
5 years minimum of 5 axis programming and operating experience
Intimate knowledge of G-Code, ability to hand write / edit programs on the fly
Up to date knowledge of contemporary machining strategies and available tooling
CMM programming and operating Mitutoyo suite or Polyworks
Parametric CAD competency Solidworks or Fusion
CNC lathe programming with live tooling
Swiss machining experience
Broad range of metrology experience
EDM experience
