**Job DescriptionJob Title:** JavaScript Quality Assurance Lead **Job Type:** Contract **Location:** Remote **About This Role** In this hourly, remote contractor role, you will work as a JavaScript Quality Assurance Lead to oversee quality, consistency, and trainer performance across JavaScript AI training projects. You will review AI-generated JavaScript code and trainer/QA work, evaluate output quality against project guidelines, provide precise written feedback, and ensure that all contributors follow the expected quality standards. You will assess work for code correctness, reasoning quality, runtime behavior, debugging accuracy, readability, maintainability, performance, security awareness, test coverage, formatting, instruction-following, and adherence to project-specific rubrics. You will spot recurring quality issues, communicate updates to trainers and QAs, support onboarding, maintain documentation, and help activate contributors who are not working consistently. This role requires strong JavaScript expertise, strong English communication skills, excellent attention to detail, structured communication, and the ability to manage quality workflows across remote technical teams. This role is a fast-growing AI Data Services company delivering training data for many of the world’s largest AI companies and foundation-model labs. Your JavaScript quality leadership will directly help improve the world’s premier AI models by ensuring that JavaScript training data is accurate, executable, logically sound, clearly explained, well-documented, and aligned with client expectations. Selection process involves an AI interview, a domain-specific task, and an interview with a recruiter. Important: There is no immediate project for this role; however, if qualified, you will be among the first experts we reach out to when relevant opportunities arise. This will also provide you with access to future projects available through our expert network. **Your Profile**

*   Bachelor’s or Master’s degree in Computer Science, Software Engineering, Information Technology, or a closely related field; equivalent professional software engineering experience may be considered.
*   Strong grasp of the English language to follow project guidelines, communicate with teams, and provide clear technical feedback in English.
*   3+ years of professional experience in JavaScript development, frontend engineering, backend development with Node.js, full-stack engineering, code review, software QA, technical mentoring, or related workflows.
*   Strong understanding of core JavaScript concepts such as closures, scope, hoisting, prototypes, promises, async/await, event loop, modules, DOM manipulation, error handling, data structures, and modern ECMAScript features.
*   Ability to evaluate JavaScript content against detailed rubrics and identify issues such as incorrect logic, non-executable code, flawed reasoning, missing edge cases, poor async handling, security risks, performance problems, hallucinated APIs, or incomplete explanations.
*   Familiarity with common JavaScript ecosystems and tools such as Node.js, npm/yarn/pnpm, React, Vue, Express, Jest, Mocha, Playwright, ESLint, Prettier, Vite, Webpack, Babel, or browser developer tools is preferred.
*   Experience leading or supporting remote teams of trainers, annotators, reviewers, engineers, technical writers, coding mentors, or QAs is strongly preferred.
*   Comfortable working in fast-moving remote environments using tools such as Discord, Google Sheets, Google Docs, trackers, dashboards, GitHub, and project management systems.
*   Highly detail-oriented and organized, with the ability to maintain style guides, FAQs, trackers, onboarding materials, honeypots, calibration tasks, and other quality documentation.
*   Experience with AI training, data annotation, large language models, prompt/response evaluation, code content QA, or rubric-based LLM evaluation is a strong plus.

**Key Responsibilities**

*   Quality monitoring: Spot-check JavaScript items, identify quality issues, provide ongoing feedback through DMs, and escalate recurring or critical issues.
*   Code review: Evaluate AI-generated JavaScript code, debugging responses, implementation explanations, algorithmic solutions, frontend/backend snippets, tests, and step-by-step reasoning for correctness and clarity.
*   Trainer and QA communication: Update trainers and QAs on Discord about new item guidelines, project changes, workflow updates, quality expectations, and JavaScript-specific review standards.
*   Question handling: Respond to trainer/QA questions clearly and promptly, especially around JavaScript behavior, async logic, browser vs Node.js environments, frameworks, package usage, testing, edge cases, and rubric interpretation.
*   Trainer/QA activation management: DM contributors who are inactive or not working, encourage activation, track follow-ups, and flag availability issues when needed.
*   Documentation: Create and maintain JavaScript project documentation, including style guides, trackers, FAQs, quality notes, examples, honeypots, calibration tasks, and onboarding materials.
*   Onboarding and training: Schedule and run onboarding/training calls with trainers and QAs to explain project expectations, workflows, rubrics, quality standards, and JavaScript-specific review requirements.
*   Quality alignment: Ensure all trainers and QAs apply JavaScript review guidelines consistently and understand updates as projects evolve.
*   Risk and security review: Flag unsafe, misleading, insecure, or overconfident code recommendations, especially around injection risks, dependency usage, authentication, browser security, data handling, and production readiness.
*   Process improvement: Identify recurring quality gaps, propose workflow improvements, and help build scalable QA processes for JavaScript AI training projects.

👩🏻💻 Développeur Freelance 🚀

**Your Mission** Cello is the Revenue Growth Infrastructure for modern digital businesses. We help teams acquire, retain, and monetize customers at scale by turning word-of-mouth into a systematic, measurable growth channel - built for the AI era. We’ve raised $10.3M total funding led by top-tier investors, and we’re now looking for a Senior Software Engineer - Full Stack (m/f/x) to help us realize our committed vision. TL;DR

*   Seed, GrowthTech
*   Remote-first, Europe-based (must be within CET +/-3 hours)
*   Competitive salary + eVSOPS

**Why join**

*   GrowthTech scale-up with $10.3M in funding from top-tier investors.
*   Exciting product: APIs, attribution models, MCP integration, AI-based recommendation engines, and assistants - not your typical CRUD app.
*   Real traction - 30+ new customers every month, 10M+ end users monthly.
*   Small team, so you'll genuinely shape how we build things.
*   You'll touch everything from frontend widgets to backend infrastructure to data pipelines. The work doesn't get repetitive.
*   We actively learn about new tech and AI tools and adopt where we can — we have to, because our customers do.
*   Remote-first, but we get together regularly - company-wide and as an engineering team.
*   The founding team consists of serial founders and experienced big-tech operators from Twilio, Wise, and Skype.

What We’re Building We help SaaS companies turn their users and partners into a sales channel through referrals, sharing, and recommendations - **10M+ end users** interact with our system every month. Our widgets live inside customer products, which means your code runs in **environments you don't control**. On top of that: APIs that customer developers integrate against, and a portal where customers manage their campaigns and analytics. Under the hood: attribution across complex user journeys, AI-based recommendation engines, multi-tenant infrastructure serving hundreds of customers, scaling millions of events. Deeper than you'd expect from a referral tool. Our product is integrated by customer developers - and that world is changing fast. The people building against our APIs and widgets range from **corporate engineering teams to solo founders using AI coding agents**. Keeping up with how developers work today, and making sure our product fits into all of those workflows, is one of the more interesting challenges here. **Job Description**

*   Stack: React
*   NestJS
*   Python
*   You'll start with well-scoped tasks and ramp up from there - we don't expect you to know everything on day one.
*   Build features, fix bugs, and gradually take on more ownership as you learn the product.
*   You'll work alongside senior engineers who'll help you grow, but we won't spoon-feed you either.
*   We use AI tools heavily in our workflow - you'll be expected to leverage them to move fast and learn faster.

**RequiredAbout You**

*   Good English (written & spoken)
*   Some experience with React (or similar) and NestJS/Python (or similar) - you don't need years, but you need to have built something real.
*   Hungry to learn. What you might lack in experience, you make up in energy and curiosity.
*   You're enthusiastic about AI tools and actively use them to punch above your weight - but you've also written code that works without AI doing the thinking for you.
*   Eager to learn the product and the domain, not just the tech.
*   Strong work ethic - you take ownership, ship what you commit to, and don't need to be chased

_Nice-to-haves_

*   Experience with mobile development (React Native, Flutter, etc.)
*   AWS exposure - not a must, but willingness to learn is
*   Side projects or a portfolio that shows you like building things

**Benefits** In the end, it’s all about the team and our culture. Understand why we love our job and see what it’s like to work at Cello in our People Playbook. We have some compelling perks and benefits: https://cello-growth.notion.site/People-Playbook-59cf404a0de5444ab0732ec905925179?source=copy\_link **About Us⭐** We are the Revenue Growth Infrastructure for digital businesses to acquire, retain, and monetize customers - at scale in the AI era. Cello turns word-of-mouth into a systematic growth channel. Our referral platform allows users and affiliates to share and discover any software product with only a few clicks. By inspiring users to share the products they love, we are virtually reinventing how companies sell and market products. Category leaders including Typeform, Miro and Veed trust Cello to accelerate their growth flywheel.
