About Arcturus

Arcturus is creating a new wire technology stack that uses carbon nanomaterials to overcome the materials limitations of metals where performance breaks down, at real operating temperatures. Our technology is designed to significantly improve the performance of electric motors for drones and robotics, heat sinks, and ultimately the entire energy grid.

Why you should join us

This is a ground-floor opportunity to help build something that has never been done before.

You would join as a founding engineer and become Arcturus’ first additive manufacturing engineer, with the chance to define the company’s metal printing strategy from the beginning. You will work directly with the Founder and CEO to shape the technical direction of our manufacturing platform and help build a category-defining materials company from scratch.

Purpose

We are seeking a Lead Additive Manufacturing Engineer who can own the development of Arcturus’ metal printing platform across LPBF and DED-based approaches, starting with aluminum and copper systems infused with carbon nanomaterials like graphene and carbon nanotubes. This person should be deeply fluent in how metal additive systems actually work, from lasers and optics to melt pool behavior, thermal history, shielding environments, material delivery, and process control, and be able to translate that knowledge into repeatable, scalable manufacturing capability.

The role

This role reports directly to the CEO

What you’ll do

• Own Arcturus’ additive manufacturing roadmap across LPBF and DED workflows for infused metal parts and wire

• Define and optimize print processes for copper and aluminum, including parameter development, thermal management, build strategy, and system-level tradeoffs

• Establish process windows that preserve conductivity, mechanical integrity, and nanomaterial performance through fabrication

• Serve as the company’s internal expert on metal AM process physics, machine behavior, lasers, and print quality

• Lead design-for-additive-manufacturing decisions, including build orientation, support strategy, scan strategy, and geometry tradeoffs that affect printability and final part performance

• Diagnose and solve print failures including porosity, cracking, distortion, poor bonding, and geometry drift

• Build qualification plans, process documentation, and acceptance criteria for repeatable development and future scale-up

• Define feedstock, shielding gas, and contamination-control practices that preserve material quality and process repeatability
