## Job description

At Atom Computing, we build quantum computers using arrays of optically trapped neutral atoms that will empower customers to achieve unprecedented computational breakthroughs. Join a world-class team of scientists, engineers, and business professionals to advance the state-of-the-art in quantum computing.

Atom Computing is seeking a Principal Opto-Mechanical Engineer to help lead the design of opto-mechanical subsystems, while also assisting with fixturing, assembly, alignment, test, and integration.

Job Responsibilities

- Initiate and lead the design and specification of complex, next-generation opto-mechanical systems, ultra-high vacuum chambers, and mechanical infrastructure from the component level up to the system level.
- Collaborate with technical leaders across engineering domains to define product requirements and inform the next-generation hardware development lifecycle.
- Partner with physicists and subject matter experts to architect robust mechanical solutions for optical assemblies, ensuring high-precision stability, thermal performance, and alignment integrity.
- Establish and enforce rigorous design standards and best practices for opto-mechanical engineering, including leading critical design reviews, performing advanced tolerance analysis, and driving Design for Manufacturing and Assembly (DFMA) to ensure scalability.
- Provide high-level technical leadership and oversight for the hands-on assembly, alignment, and system integration of critical opto-mechanical designs.
- Mentor junior team members, generate internal training documentation, and drive technical growth and standardization within the engineering organization.
- Participate in long-term technical program planning, including contributing to roadmap development and resource assessments to ensure alignment with company goals.
- Contribute as a subject matter expert to technical documentation, grant proposals, and IP generation (patents and inventions).
- Oversee external vendor relationships for complex component development, managing the design process and defining key deliverables.
- Troubleshoot complex technical issues across the product lifecycle, both at Atom and off-site customer facilities.
- Capable of lifting and moving objects that weigh up to 25 pounds.

## Experience & Education

- Bachelor’s degree in Mechanical Engineering, advanced degree is a plus
- 10+ years opto-mechanical design experience
- 8+ years of hands-on optics assembly experience in a laboratory environment

## Qualifications

- Deep expertise and demonstrated leadership in the design and build of complex opto-mechanical systems
- Proven track record of driving complex technical initiatives from conception through deployment, and the ability to mentor and scale the engineering team's capabilities
- Mastery of SolidWorks, PDM, or equivalent design and data management software
- Strong background with FEA (meshing, modal analysis, thermal analysis, etc.) and corresponding first order analysis
- Deep understanding of material science related to adhesives in an optical environment
- Ability to own and mentor team members in DFMA, tolerancing, drawings to ASME Y14.5M and ISO 10110
- Strong knowledge of first order optics and aberration theory
- Robust history in precision mechanisms and kinematic systems
- Ability to work effectively in an open, collaborative environment
- Excellent communication, listening, and people skills

Atom Computing provides a wide variety of perks and benefits, including fully paid medical, dental, and vision insurance for our employees and their dependents. Additionally, unlimited paid time off, 401K company matching, short- and long-term disability, FSA, dependent care benefits, and life insurance.  We also offer drinks, snacks, and catered team lunches in our offices, every day!

The base salary range for this position is between $160,000 - $185,000, commensurate with experience. In addition to salary, we offer an annual bonus and equity in the company.

## About Atom Computing

## Company Overview
- **One-liner**: Atom Computing builds large-scale, gate-based quantum computers using arrays of optically-trapped neutral atoms to help companies and researchers achieve unprecedented computational breakthroughs.
- **Entity Type**: Private (funded; $60M Series B closed January 2022, ~$191.2M total funding across 12 rounds)
- **Headquarters**: Berkeley, California, United States
- **Founded**: January 2018
- **Founders**: Ben Bloom (Founder & CTO), Jonathan King (Co-Founder & Chief Scientist); Rob Hays serves as CEO & President

## Core Business
- **Primary industry**: Quantum computing / quantum hardware and software
- **Target customers**: B2B; enterprise researchers, commercial quantum algorithm developers, national labs, and scientific institutions seeking on-premises quantum systems
- **Mission or purpose**: Building large-scale quantum computers to enable breakthrough discoveries and tackle increasingly challenging applications, with a clear path to fault tolerance.

## Products & Services
- **[AC1000 — Quantum Computing Platform]**: A universal, gate-based quantum computer commercially available for on-premises deployment. Features 1,200+ physical qubits, all-to-all qubit connectivity, better-than-threshold fidelities, mid-circuit measurement with qubit reuse/reset, and real-time conditional branching — designed to support building logical qubits.
- **[Partner Program]**: Early-access collaboration program for software and application development partners to explore quantum algorithms, provide feedback, and work alongside Atom Computing's technical team on real-world applications.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of ~$191.2M across 12 rounds (as of 2026); latest reported annual revenue ~$5.3M
- **Notable Investors/Partners**: Third Point Ventures (led Series B), Innovation Endeavors, Prelude Ventures, National Science Foundation (grants)
- **Growth Signals**:
  - Headcount grew ~63.6% YoY to 98 employees (2026), with +2.4% monthly growth
  - 31 active job postings; job postings up +520% year-over-year and +93.8% quarter-over-quarter
  - Expanded to offices in Berkeley, Boulder, and Austin; workforce distributed across United States and Denmark
  - 24 scholarly works with ~9,800+ citations; field-weighted citation impact of 3.7; 67% open access
  - Published industry-leading coherence times (>40s) on nuclear spin qubits in Nature Communications

## Competitive Advantages
- **Massive scalability**: Neutral-atom qubits are held microns apart by focused lasers, have no electrical charge, and can be tightly packed into arrays scaling to thousands or millions of qubits without a substantial increase in system footprint
- **Long coherence**: Use of alkaline-earth metal atoms with closed outer electron shells delivers industry-leading coherence times and insensitivity to environmental noise
- **Reduced complexity**: All qubit control is mediated by light through free space rather than individual electrical cables per qubit — a simpler path to scale
- **High fidelity**: Neutral atoms are intrinsically identical and present no fundamental physics obstacles to reaching fault-tolerant thresholds
- **Advanced technical capabilities**: First-mover positioning with mid-circuit measurement, qubit reuse/reset, and real-time conditional branching on a 1,200+ qubit commercial system

## Strategic Focus
- Advancing toward fault-tolerant quantum computing and logical qubits
