## Job description

## 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. At its core, Arcturus is developing a new class of carbon nanomaterial-infused metal matrix composites for high-performance conductor applications.

## 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 an early technical co-op and work closely with Arcturus’ technical team across nanomaterials, additive manufacturing, process engineering, and testing. This is a hands-on role for someone who wants to learn quickly, contribute directly, and help build the experimental foundation for a first-of-its-kind materials platform.

Purpose

We are seeking a Research and Prototyping Engineer Co-op who can support the technical team across experiments, literature research, supplier research, sample preparation, fixture development, testing, and documentation.

This role is intentionally broad. You do not need to be an expert in every area, but you should be highly curious, organized, hands-on, and excited to work at the intersection of materials science, advanced manufacturing, and electrification.

## The role

This role will work closely with Arcturus’ technical leads and senior engineers.

Nanomaterials

- Build and maintain a carbon nanomaterial and powder supplier database, including vendors, material specs, pricing, lead times, and sample availability
- Help organize a recipe matrix for carbon nanomaterial integration, including material type, loading level, feedstock, processing route, and resulting performance
- Support basic nanomaterial handling, sample preparation, documentation, and experimental tracking

Additive Manufacturing

- Help build and maintain chamber BOMs, equipment lists, vendor quote trackers, and component comparison tables
- Support fixture and tooling development through CAD, ideally in Onshape or a similar CAD platform
- Help organize a fixture CAD library for experimental setups, sample holders, coupons, and test hardware
- Support additive manufacturing experiments through preparation, documentation, build tracking, and post-build sample handling

Process Engineering

- Support flash sintering fixture iterations, including CAD updates, part sourcing, assembly, testing, and documentation
- Help create and improve sample preparation SOPs for polishing, sectioning, mounting, cleaning, labeling, and tracking
- Support cylinder coupon workflows, including sample preparation, processing, inspection, measurement, and documentation
- Help translate experimental procedures into clear, repeatable work instructions and lab notes

Testing and Characterization

- Support internal materials testing, including Raman spectroscopy, electrical characterization, mechanical characterization, polishing, microscopy, and other methods as needed
- Help prepare samples and data packages for external testing, vendor evaluation, partner validation, and customer-facing demonstrations
- Coordinate with external vendors and labs for quotes, sample shipments, testing status, and results tracking
- Maintain clear technical documentation, including lab notes, test summaries, experimental results, and lessons learned

## Basic qualifications

- Currently pursuing or recently completed a BS, MS, or PhD in materials science, mechanical engineering, chemical engineering, electrical engineering, physics, chemistry, manufacturing engineering, or a related technical field
- Strong technical curiosity and willingness to learn across multiple disciplines
- Comfortable working hands-on in a lab, shop, or experimental environment
- Highly organized, detail-oriented, and reliable with documentation
- Able to take direction, ask good questions, and execute quickly
- Excited to work in a fast-moving startup environment where priorities can change quickly

## Preferred qualifications

- Experience working in a research lab, hardware startup, university lab, or advanced manufacturing environment
- Experience with carbon nanomaterials, graphene, carbon nanotubes, metallurgy, additive manufacturing, powder processing, or materials characterization
- Familiarity with Raman spectroscopy, microscopy, SEM/EDS, electrical testing, mechanical testing, polishing, or sample preparation
- CAD experience, ideally with Onshape or similar tools
- Experience with literature reviews, supplier research, technical databases, or experimental documentation

## What we offer

- Hands-on technical experience with first-of-its-kind materials and manufacturing challenges
- The chance to work closely with senior technical leads across nanomaterials, additive manufacturing, process engineering, and testing
- Real ownership over useful technical projects, databases, fixtures, experiments, and documentation
- Up to a one-year co-op experience with direct exposure to early-stage deeptech startup building. If the fit is right, we'd love to bring you on to the team!

If this role excites you, even if you do not check every box, we’d love to hear from you. We’d rather work with a fast learner who cares deeply about the work than someone with years of experience but little curiosity.

## About Arcturus

## Company Overview
- **One-liner**: Infusing carbon nanomaterials into metals to create a new class of electrical conductors that break past the limits of conductivity and strength at high temperatures.
- **Entity Type**: Private (no public funding rounds disclosed; received a 1517 Flux Capacitor Fellowship in 2024)
- **Headquarters**: Los Angeles, California, USA
- **Founded**: 2005 (per Built In)
- **Founders**: Amir Mashal (Founder & CEO)

## Core Business
- **Primary industry**: Advanced materials / manufacturing – specifically electrical conductor technology for energy transmission, electric vehicles, drones, robotics, data centers, and grid infrastructure.
- **Target customers**: B2B / enterprise – utilities, aerospace, automotive, and industrial hardware companies.
- **Mission or purpose**: Reinvent the conductor to modernize the energy grid, lower electrification costs, and enable next‑generation electric motors.

## Products & Services
- **Carbon Nanomaterial‑Infused Metal Conductors**: A proprietary technology stack that embeds carbon nanomaterials into metals to maintain high conductivity at extreme temperatures, enabling lighter, stronger, and more efficient wires for power transmission, motors, and high‑performance electronics.

## Market Standing
- **Valuation/Market Cap**: Not publicly available
- **Key Metric**: 31 total employees (Built In); 9 open job postings as of June 2026 (JobPin)
- **Notable Investors/Partners**: 1517 Fund (awarded the Flux Capacitor Fellowship in June 2024)
- **Growth Signals**: Actively scaling the engineering team (8–9 roles in research, process engineering, operations); hybrid/remote options; expanding from laboratory prototype toward industrial‑level production.

## Competitive Advantages
- **Proprietary carbon nanomaterial‑metal infusion** – a difficult‑to‑replicate materials‑science breakthrough that addresses the fundamental limits of traditional copper and aluminum conductors at high temperatures.
- **Integrated approach** solving materials chemistry, manufacturing scale‑up, and product design simultaneously, creating a moat around both the know‑how and the process.

## Strategic Focus
- **Industrial scale‑up**: Proving the manufacturing process at industrial volume while maintaining material properties.
- **Market entry**: Targeting the most demanding segments first – grid transmission, electric aviation, robotics, and high‑performance data center power delivery.

## Why Work Here
- Hands‑on, garage‑style engineering culture focused on solving one of the hardest problems in materials science.
- Hybrid work model (combination of remote and on‑site) with offices in Los Angeles and additional locations per Built In.
- Opportunity to be a founding‑stage engineer in a company that has already demonstrated proof of concept and is now scaling toward production.
- Strong emphasis on autonomy and impact: “If you’re an engineer reading this and that didn’t slow you down, we want to meet you.”
