HIRE DEVELOPERS  /  CHROME EXTENSION DEVELOPERS

Chrome extension engineering

Chrome extensionsbuilt right -not just built fast.

We've built Chrome extensions for enterprise clients and consumer products — including the RichmondGPT extension and interactive school management extension. If you need a Chrome extension developer who understands Manifest V3, service workers, and Chrome Web Store approval, we've got them.

Why Entalogics

Why teams hire
Chrome extension developers from us.

Our Chrome extension developers know the full extension architecture — background service workers, content scripts, popup UIs, options pages, and cross-origin messaging. We build to Manifest V3 standards, handle Chrome Web Store submission and review, and ensure extensions are secure, performant, and compliant with Google's policies.

EXPERT BENCH01

Expert Chrome extension developers, only.

Every developer has been vetted for extension-specific skills — Manifest V3 architecture, service worker lifecycle, content script injection, Chrome APIs, and real experience getting extensions approved and published on the Web Store.

FAST HIRING02

Fast hiring process.

Three matches and we get it. Embedded developers in days, not weeks. No endless interviews, no waiting periods.

FLEXIBLE ENGAGEMENT03

Flexible engagement.

Full-time for a product extension, part-time for maintenance and Chrome updates, or hourly for Web Store review issues and MV3 migration. Pick what fits.

Hiring model

Three ways
to staff your build.

Chrome extension development looks simple until you hit the hard parts — Manifest V3 migration, service worker limitations, cross-origin restrictions, content security policies, and Web Store rejection. Our developers have navigated all of these on real projects and know how to build extensions that get approved and stay approved through Chrome updates.

Full-time hiring

A dedicated Chrome extension developer working exclusively on your product full-time. They follow your processes, join your standups, and own the extension — from architecture to Web Store submission. Best for teams building an extension as a core product.

M0280h / mo

Part-time hiring

Focused extension expertise for 20 hours per week. Great for teams maintaining a published extension, handling Chrome version updates, or adding features on a schedule without a full-time commitment.

M0340h blocks

Hourly hiring

On-demand extension consulting for targeted problems — Manifest V3 migration, Web Store rejection debugging, service worker issues, or content script architecture review. Pay only for what you need, when you need it.

  • Developer in your Slack & GitHub
  • Reports into your product lead
  • Same hiring bar — you direct
03

Hybrid model

Your team handles backend APIs and product decisions. Our extension specialist handles the browser-side work — service workers, content scripts, permissions, and store review.

  • Specialists from us, generalists from you
  • Shared standups + async reviews
  • Clear DRI per layer
Stack & tooling

Technologies our
Chrome extension developers use competently.

Our Chrome extension developers come from strong web and systems engineering backgrounds. Here's the core stack they use to build secure, maintainable extensions.

Chrome Extension API

Core Chrome APIs for tabs, storage, scripting, and extension lifecycle management.

Manifest V3

Current extension manifest — service workers, declarativeNetRequest, and permission model.

WebExtensions API

Cross-browser standard for extensions that run on Chrome, Firefox, and Edge.

Firefox Add-ons

Firefox extension packaging and review for cross-browser distribution.

Edge Extensions

Microsoft Edge extension publishing via Partner Center and Chromium compatibility.

COMMON QUESTIONS

Straight answers.

Six questions we get on every first call about hiring Chrome extension developers. If yours isn't here, we'll cover it first.

Productivity tools, AI-powered page assistants, enterprise browser management, content blockers, developer utilities, and SaaS companion extensions. From simple popup tools to complex extensions with content scripts, service workers, and external API integrations.
Yes — exclusively. Google has fully enforced Manifest V3 for new submissions. Every extension we build uses MV3 service workers, declarativeNetRequest, and Chrome's current permission model. We also migrate existing MV2 extensions to MV3.
Yes. We use the WebExtensions API standard where possible for cross-browser compatibility. Chrome-specific APIs get polyfilled or abstracted for Firefox and Edge. One codebase, multiple browser targets.
Yes. We prepare the listing, screenshots, privacy policy, and permission justifications. We know the common rejection reasons — overly broad permissions, unclear purpose, missing privacy disclosures — and address them before submission.
Yes. Service workers communicate with external APIs via fetch. For native app integration, we use Chrome's Native Messaging API. For real-time communication, we use WebSocket connections from the service worker with proper reconnection handling for MV3's idle termination.
Simple popup extensions: 2–4 weeks. Complex extensions with content scripts, service workers, and backend integration: 6–10 weeks. MV2 to MV3 migrations: 4–8 weeks depending on the extension's complexity and use of deprecated APIs.
