About Atomic Semi

Atomic Semi is developing a next-generation semiconductor fabrication facility focused on speed, simplicity, and rapid innovation. The company designs and builds its own semiconductor manufacturing tools, enabling faster experimentation and continuous improvement across the entire hardware stack — from fabrication systems to chip architecture.

Founded by Sam Zeloof and Jim Keller, the company combines deep semiconductor expertise with an ambitious engineering culture focused on practical problem-solving and rapid prototyping.

Atomic Semi operates as a highly hands-on engineering environment where teams design, prototype, test, and refine complex systems in days or weeks rather than months.

About the Engineering Teams

Positioning Team

  • Designs advanced lithography, motion control, and metrology systems for semiconductor fabrication equipment.

Vacuum Team

  • Develops semiconductor processing systems including deposition, annealing, etching, and supporting infrastructure with emphasis on scalability and automation readiness.

Packaging Team

  • Builds semiconductor packaging equipment such as laser ablation systems, automated plating systems, and reflow processing tools.

Automation Team

  • Creates robotic automation systems to accelerate semiconductor packaging manufacturing.

Role Overview

Atomic Semi is seeking talented Mechanical Engineers to design, prototype, assemble, and improve specialized semiconductor fabrication equipment.

The role requires engineers who are highly practical, technically versatile, and comfortable working across mechanical, electrical, optical, and automation systems. Candidates should be capable of managing projects from concept development through final assembly and testing.

This position is ideal for individuals who enjoy rapid development cycles, experimental engineering, and hands-on hardware creation.

Key Responsibilities

  • Design and improve semiconductor fabrication and packaging equipment
    Develop mechanical assemblies, frames, and precision components
    Integrate electrical, optical, and mechanical subsystems into complete machines
    Support system assembly, wiring, calibration, and optical alignment
    Work closely with multidisciplinary engineering teams to optimize manufacturing processes
    Source components, manage vendor relationships, and ensure project specifications are met
    Rapidly prototype and validate new engineering concepts

Required Qualifications

  • 2–7 years of professional experience in mechanical or electromechanical system design
    Strong hands-on experience with prototyping, assembly, and hardware development
    Bachelor’s degree in Mechanical Engineering, Electrical Engineering, Mechatronics, Automation, Physics, or related field
    Ability to independently own projects from design through testing

Preferred Qualifications

  • Master’s degree with additional relevant industry experience
    Experience building laser-based systems and opto-mechanical equipment
    Background in both R&D and manufacturing environments
    Knowledge of system integration involving mechanical, electrical, and software components
    Basic programming skills for machine control or automation
    Experience designing custom instrumentation or control electronics
    Personal workshop, lab, or independent engineering project experience
