Work EnvironmentOften involves editing drafts, working with writers or editorsPrimarily reviews final texts for errors
Employer & IndustryPublishing, media, marketingPublishing, academic, journalism
Search & Comparison IntentPeople compare editing roles, looking for detailed editing tasksPeople seek error-checking roles, focusing on final review

Part Time Copy Editing involves actively revising and improving content, requiring editing skills and familiarity with style guides. In contrast, Part Time Proofreading focuses on catching grammatical, spelling, and punctuation errors in final drafts. Both roles are common in publishing and media industries but serve different stages of the editing process.

What are the key skills and qualifications needed to thrive as a Part Time Copy Editor, and why are they important?

To thrive as a Part Time Copy Editor, you need excellent grammar, punctuation, and spelling skills, often supported by a background in English, journalism, or a related field. Familiarity with style guides (such as AP or Chicago Manual of Style) and proficiency with editing tools like Microsoft Word, Google Docs, and track changes features are typical requirements. Strong attention to detail, time management, and effective communication help you stand out in this role. These abilities ensure clear, error-free content and efficient collaboration, which are crucial for meeting deadlines and maintaining publication quality.

What is part time copy editing?

Part time copy editing involves reviewing and correcting written content for grammar, spelling, punctuation, and style on a flexible or reduced-hour schedule. Part time copy editors work with various types of materials, such as articles, websites, or marketing materials, to ensure clarity and consistency. This role allows professionals to balance work with other commitments while still contributing to high-quality published content.

How do part-time copy editors typically balance multiple projects and deadlines while working with different teams?

Part-time copy editors often juggle assignments from various clients or departments, which requires strong organizational skills and clear communication. They usually manage multiple deadlines by prioritizing tasks, using project management tools, and maintaining regular check-ins with writers and project leads. Collaboration is key, so part-time editors frequently coordinate with content creators, marketing teams, or publishers to clarify expectations and ensure consistency in style and tone. This dynamic environment helps copy editors build versatility and expand their professional network, which can lead to additional opportunities.

Atomic Machines

Emeryville, CA • Hybrid

$90 - $120/hr

Part-time

Posted 3 hours ago

Job description

Atomic Machines is ushering in a new era of micromanufacturing with its Matter Compiler™ technology platform. This platform enables new classes of micromachines to be designed and built by providing manufacturing processes and a materials library that are inaccessible to semiconductor manufacturing methods. It unlocks MEMS manufacturing not only for device classes that could never be produced by semiconductor methods, but also for entirely new categories. Furthermore, this digital platform is fully programmable in the way 3D printing is digital—but whereas 3D printing produces parts of a single material using a single process, the Matter Compiler™ technology platform is a multi-process, multi-material system: bits and raw materials go in, and complete, functional micromachines come out. The Atomic Machines team has also created an exciting first device—made possible only through the Matter Compiler™ technology platform—that we will be unveiling to the world soon.
Our offices are in Emeryville and Santa Clara, California.
About The Role

In this role you will help maintain and extend a web-based visual graph editor for manufacturing workflows. Users create and connect nodes representing materials/workpieces/tools and manufacturing steps (processes/inspections), validate the resulting workflow against catalogs and strict data contracts, and export a schema-compliant JSON representation for downstream tooling.

This role blends UI engineering with data integrity work. The editor must stay responsive on large graphs, preserve correctness (IDs, validation, export format), as well as support collaboration workflows through version control integrations.

This is a part-time, hybrid, freelance/contract role. Hours:

  • 1st 60 days: 20-40 hours per week
  • Ongoing: 10-20 hours (minimum) per week
What You'll Do
  • Build and maintain a React + TypeScript UI for a graph editor (node/edge creation, selection, multi-select, drag/drop, property panels)
  • Implement schema-driven validation and export (JSON Schema / AJV), ensuring stable, backwards-compatible outputs as schemas evolve
  • Improve performance and reliability for large graphs (rendering, minimizing re-renders, preventing UI jitter, safe persistence)
  • Support workflows around identity/ID rules, including ID generation, transformations on copy/paste/import, and "minting/locking" behaviors that freeze certain fields once finalized
  • Maintain integrations used in real production workflows:
    • GitLab API (branching, committing files, MR workflows)
    • Methods API (catalog sync, offline fallback, validation that blocks pushes when API is down)
    • Authentication (Okta)
  • Ship small-to-medium features end-to-end: UI, state changes, validation, tests, and docs
  • Triage bugs from real users (manufacturing/process engineers), reproduce quickly, and implement safe fixes
  • Add/maintain unit tests (Jest + TS) around tricky logic (ID transformation, export validation, API sync behavior)
  • Keep the build/lint/test pipeline healthy (Vite, TypeScript, ESLint, Jest) and handle dependency upgrades carefully
  • Collaborate asynchronously with a cross-functional team (process, production, AI) through clear PRs, strong commit hygiene, and pragmatic technical decisions
  • Tools/Stack You'll Work With: React 18, TypeScript, Vite, Tailwind CSS, ReactFlow, AJV (JSON Schema), Jest, ESLint, GitLab API, OpenAPI, Okta
What You'll Need
  • Experience building complex, stateful UI systems (not CRUD/dashboard apps)
  • Strong React + TypeScript with state management + performance optimization
  • Experience with graph/diagram editors or similar interaction-heavy UIs
  • Experience with large in-memory data + UI/data synchronization
  • Experience with validation systems + deterministic outputs (schema, exports)
  • Strong debugging in complex systems + ability to explain tradeoffs
  • Experience leading complex, ambiguous problems across cross-functional teams with multiple stakeholders
Bonus Points For:
  • Manufacturing background (MES, process planning, CAD/CAM adjacent tooling, "recipes/methods/catalog" concepts)
  • JSON Schema / AJV experience and comfort with strict data contracts
  • GitLab API experience, auth systems (Okta/OIDC), or "internal tool" deployment constraints

$90—$120 USD
