Atom Computing Other Engineering

• Full-time Boulder, CO, USA USD 140k-165k / year + Equity Posted on Sep 15, 2026 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, engineering, and business professionals to advance the state-of-the-art in quantum computing. We're looking for a Mechanical Engineer to join our Opto-Mechanical Engineering team to focus on designing the physical systems that house, protect, and connect our Control Systems and associated electronic products - from enclosures and chassis to thermal management and cabling. You'll work closely with electrical, firmware, and systems engineers to turn functional requirements into manufacturable, reliable hardware, primarily for 19" rack-mount and other pluggable instrumentation form factors. This is a hands-on mechanical design role covering the full product lifecycle: concept, CAD modeling, analysis, prototyping, and production support. This position is located in Boulder, Colorado, and will report to the Opto-Mechanical Engineering Manager. Responsibilities

Design enclosures, heat sinks, shields, cabling, chassis, and front panels for rack-mount and pluggable instrumentation products

Create and maintain detailed CAD models, assemblies, and drawings

Perform thermal and airflow analysis to ensure components stay within operating temperature limits under real-world conditions

Designing in sheet metal, extrusions, and machined parts as well as rapid prototyping (3D printing and other quick turn methods)

Assist with connector and cable analysis and design; assess board and front panel space requirements and density, cable routing and restrictions, etc

Conduct tolerance studies (GD&T-based) to ensure fit, function, and manufacturability across assemblies

Collaborate with electrical engineers to integrate PCBs, power supplies, and wiring into mechanical packaging

Support design reviews, prototyping, testing, and validation (thermal, structural, EMI/EMC as applicable)

Work with manufacturing, suppliers, and operations to ensure designs transition smoothly from prototype to production

Experience & Education

BS in Mechanical Engineering

5+ years of mechanical engineering design experience relatable to instrument design

Required Qualifications

Proficiency with CAD and simulation tools; SolidWorks and Ansys (e.g., Icepak, Mechanical, Fluent) preferred, though familiarity with similar

CAD/FEA/CFD

tools will also be considered

Experience working with mechanical fixtures for PCBs (supports, integration fixtures, multi-board design with FMC or other board-to-board mating interfaces, heat sinks, shields, connectors, etc)

Solid understanding of thermal management for electronics: heat sink design, airflow/CFD analysis, and component-level cooling

Mechanical drawing and GD&T per ASME Y14.5M, tolerance stack analysis

Experience with sheet metal design, fabrication methods, and cable/harness design

Ability to work cross-functionally with electrical and systems engineers to balance mechanical, thermal, and electrical constraints

Robust packaging of sensitive systems for shipping or extreme environments

Comfortable moving between early-stage concept work and detailed production-ready design

Desired Qualifications

Familiarity with pluggable instrumentation standards such as MicroTCA, PXI, VPX, or similar and modular PCB form factors, such as FMC

Experience with RF shielding, EMI/EMC design considerations

Experience with electronics test fixture design

Exposure to test & measurement or precision instrumentation products

Experience supporting products through sustainment/value engineering after initial release

Familiarity with PLM and PDM tools
