 We're Hiring: Web Scraping Support Engineer (Remote)

Hello everyone! Massive is looking for a Web Scraping Support Engineer to join our fully remote team. If you dream in selectors, wake up parsing HTML, and genuinely enjoy helping people solve gnarly data extraction problems — this one's for you.

 What is Massive?
Massive is an infrastructure company powering data-driven innovation at scale. We operate a global proxy network, build managed APIs for search engines (SERP), and Web Unblocking API to bypass anti-bot measures for large-scale data collection and processing.

 Why This Role Is Different
Most support roles are reactive. This one isn't. You're the person customers trust when their scraping pipeline breaks at 2 AM, when a target site changes its structure overnight, when nothing works and nobody knows why. You don't just answer tickets — you solve problems that other engineers can't.

 Who We're Looking For
 

• Troubleshoots in Their Sleep: Broken selectors, anti-bot walls, rotating proxies, CAPTCHAs, headless browser quirks — you've seen it all and you fix it before your coffee gets cold
• AI is your best friend - you know how to leverage AI to be 10X faster and more productive
• Customer-Obsessed & Likable: You're the person customers ask for by name. You explain complex concepts in plain language and people genuinely enjoy working with you
• Can Scrape Anything, Anywhere: SPAs, paginated APIs, rate-limited endpoints, geo-restricted content — if it's on the web, you know how to extract it
• Consumes Data for Breakfast: You think in JSON, dream in XPath, and get excited about a well-structured dataset
• Relentlessly Organized: Your support board is pristine. Every ticket triaged, every follow-up tracked, every edge case documented. Nothing slips through — ever
• Curious Builder: When you notice the same issue three times, you don't just fix it — you automate the solution so it never comes back

 What You'll Be Doing
 

• Own the support board end-to-end with the support team — triage, prioritize, resolve, and follow up on every ticket
• Debug complex web scraping issues across proxy configurations, browser automation, and API integrations
• Help customers build, optimize, and fix their scraping pipelines
• Reproduce issues, identify root causes, and escalate bugs with full context to engineering
• Write documentation and guides that reduce repeat tickets

 Bonus Points
 

• Experience with Puppeteer, Playwright, Selenium or similar browser automation
• Hands-on with proxy networks and IP rotation strategies
• Familiarity with anti-bot systems (Cloudflare, Akamai, PerimeterX, DataDome)
• Working knowledge of Python, Node.js, or scripting languages for data extraction
• no satisfaction until all the work is done and then some

 Ready to Scrape the Future With Us?
Skip the generic resume. Show us something real — a scraper you built, a gnarly problem you debugged, a support process you transformed. We care about what you can do, not where you went to school.
If you read this and thought "finally, someone gets it" — trust that feeling. Apply now.

About the Role (Node.js)

We're looking for a curious and motivated Junior Backend Engineer to join our team. You'll be building backend services and REST APIs and working with AWS or Azure infrastructure.

Our projects use Python or C#, but since all of our code is written with AI, we are considering candidates with any OOP language, including JavaScript and Java. What matters is how you think about software: object-oriented design, APIs, and data.

We work in pairs — juniors are always paired with another junior or someone at a similar level, not just for code reviews, but for day-to-day coding, architecture decisions, and problem solving, with seniors close by whenever you need help. This is production work: you'll ship services that customers rely on, with the safety net of another teammate beside you.

The client is US-based, so the team works US business hours; for engineers in Ukraine, this means your working day ends around midnight Kyiv time. This role can be full-time or part-time, depending on your availability.

What You'll Work On

• Backend Services & APIs — build and maintain REST APIs and backend services for client platforms, with clear contracts and automated tests.
• AWS or Azure Infrastructure — work with cloud infrastructure on AWS or Azure, depending on the project.
• CI/CD using GitHub Actions or Azure DevOps pipelines.

Tech Stack

• Backend — Our projects use Python or C#, depending on the engagement. You do not need to know either one — all code is written with AI, and you'll learn the project's framework on the job.
• Cloud — AWS or Azure, depending on the engagement. Nice-to-have, not required.

Working Hours & Format

This role can be full-time or part-time, depending on your availability. It's fully remote. Our client operates on US business hours, so the schedule needs to align with US time zones — for engineers based in Ukraine, your working day will end around midnight Kyiv time.

Requirements

Solid fundamentals in OOP and comfort with at least one OOP language — it does not matter which.

Exposure to AWS or Azure is a plus, but not required — you'll pick up what you need on the job. We care more about your curiosity and attitude than your CV.

• Fluent spoken English (C1+), verified in a live call.
• Ukrainian – native (preferred).
• Hands-on work in any CRM (HubSpot, Pipedrive, Attio, Salesforce or equivalent): pipeline hygiene, stage discipline, logging every touch.
• Cold outreach at volume: LinkedIn Sales Navigator, Telegram, email sequencing.
• Ability to work across multiple projects/products in parallel and enter unfamiliar verticals quickly – research a new field, build a message that holds up, start contacting.
• High-volume orientation: comfortable spending most of the day in conversation, calls and follow-ups.
   

Responsibilities
 

• Source own pipeline through cold outreach across LinkedIn, Telegram, X/Twitter, email and niche industry platforms.
• Build and maintain target lists and segmentation for assigned directions.
• Run first contact, qualification and discovery calls.
• Convert cold contacts into warm, qualified opportunities and hand them over with full context.
• Keep warm opportunities moving: follow-ups, next steps, objection handling – the deal does not stall in this role's hands.
• Close mid-size deals independently as the scope expands into the full cycle.
• Maintain the CRM: every contact, stage, next step and outcome logged.
• Test and iterate messaging and channels per segment; report what converts.
• Ramp into new products, networks and verticals as assigned, including unfamiliar fields.
• Weekly reporting on outreach volume, calls held, warm opportunities and pipeline movement.

Fully Remote · SaaS · Cloud

TopTechPhoto is a product company building a suite of SaaS tools used by teams around the world. Our products span digital asset management (Pics.io), product information management (Toriut.com), and an AI-powered knowledge hub (Provenyx.ai). Across all three, we process large volumes of data, power complex workflows, and ship to thousands of users daily.
 

We ship fast, test rigorously, and invest heavily in automation, reliability, and smooth engineering processes.

What We Build

Our ecosystem spans three products and a shared platform underneath them:

• Pics.io — a React-based DAM web app with mobile clients and integrations for Adobe, Google Workspace, Shopify, Zoho, WordPress, and more
• Toriut.com — a PIM platform handling complex product data structures, bulk operations, and catalog workflows
• A Node.js backend powering public APIs across all products
• MongoDB, Elasticsearch, and cloud-native services on AWS & GCP
• A CI/CD pipeline that deploys multiple times per day
• A growing suite of internal tools, automations, and AI-assisted workflows supporting quality and releases

What You'll Work On

As a QA Engineer, you'll ensure that users receive updates frequently, safely, and without regressions. You'll work closely with developers, product managers, and designers throughout the entire development lifecycle — and you'll actively use AI tools to work smarter, not just harder.

Examples of challenges you'll tackle:

• Exploring web and mobile-adapted UI flows to identify issues before they reach users
• Writing, maintaining, and organising test cases in QASE
• Planning and coordinating releases across multiple teams
• Automating test scenarios using Playwright in TypeScript/JavaScript
• Validating API behaviour, client–server interactions, networking, and performance using Postman or Swagger
• Stress-testing complex media workflows — uploading, previewing, transcoding, streaming
• Ensuring Pics.io behaves consistently across browsers, devices, and environments
• Leveraging AI-assisted tools to generate test cases, analyse failure patterns, accelerate coverage, and reduce repetitive manual work

Who You Are

You're a QA Engineer who enjoys exploring systems, finding edge cases, and ensuring products behave predictably for thousands of users. You think in risk, coverage, and user impact — and you're comfortable using AI as a genuine productivity multiplier, not just a buzzword.
 

Requirements

• 2+ years of experience testing web applications
• Solid understanding of QA methodologies, SDLC, Agile, and Scrum
• Hands-on experience writing automated tests in TypeScript or JavaScript using modern frameworks — Playwright, Cypress, or similar
• Experience writing structured test documentation: checklists, test cases, bug reports
• Working knowledge of REST APIs; hands-on with Postman and/or Swagger
• Proficiency with bug tracking and test management tools — Jira, QASE, or equivalent
• Comfortable working in cross-functional teams alongside developers and product managers
• Strong analytical thinking and sharp attention to detail
• Understanding of how modern web apps work — AJAX, HTTP, CDN, caching, HTML/CSS
   

Nice to have

• Practical experience using AI tools to streamline QA — test generation, failure triage, exploratory assistance, or pipeline automation
• Experience with mobile app testing (iOS / Android)
• Familiarity with CI/CD pipelines — GitHub Actions, Jenkins, or similar
• Experience in release management
• Background in security, performance testing, or media/video streaming environments

Curiosity, independence, and attention to detail matter more than ticking every box.

How We Work

We are a senior-leaning distributed team that values high-quality and frequent releases, clear communication, and reliable processes. You'll have autonomy in organising your work, freedom to propose improvements, and full access to the product, dev and ops teams. We support continuous learning through paid tools, courses, conferences, and books — including AI tooling your role benefits from. Remote work is fully supported; your location doesn't matter as long as communication is smooth and consistent.

Test Challenge

To proceed to the interview stage, please complete a practical assignment. Register at Pics.io, explore the product, and complete both parts below.

Part 1 — Testing Plan

Choose any feature in Pics.io that genuinely interests you — we recommend starting with the video player or saved searches, but the choice is yours.

Write a testing plan for your chosen feature. We want to see your approach, structure, and how you think about quality across multiple dimensions — not exhaustive step-by-step descriptions.

Your plan should address:

• What you're testing and why you chose it
• Which testing aspects you're covering and how — for example: functional behaviour, UI and UX, API and networking, performance, security, edge cases, and cross-browser or cross-device consistency
• Core scenarios vs. secondary ones, and how you prioritise
• Which areas are worth automating and why
• Tools you'd use — including any AI tools that fit naturally
• Metrics and benchmarks you'd track
• How you'd communicate results and findings to the team

Use any format you like: Google Docs, QASE, TestRail, Notion, and so on.

Note: Avoid features that require testing auth flows or team management — those areas are protected on the backend and won't behave normally under automation or manual probing.

Part 2 — Playwright Automation

Automate a meaningful subset of what you planned in Part 1 — ideally the same feature, so we can see how your thinking translates into code.

What we expect:

• A real GitHub repository with your tests committed and pushed — not a zip file or a Gist
• Tests written in TypeScript, using Playwright
• A README.md that explains what you chose to test, why, and how to run the suite locally
• At least one AI tool used somewhere in the process — test generation, code review, selector strategy, whatever felt natural. Briefly mention in the README which tool you used and where it helped

Reviewing the Test Challenge:

We're not counting test cases. We want to see how you structure a suite, how you handle selectors and assertions, how readable your code is, and whether you made a deliberate choice about what's actually worth automating. A small, well-reasoned set of tests beats a large, flimsy one.

There are no deadlines or time limits. Send us links to both your testing plan and your GitHub repository when you're ready.

A note before you answer Qualifying Questions (Контрольні запитання):
We're looking to get to know you as a person, not review a polished AI-generated response. These questions have no right answers — we're genuinely curious how you think. Candidates who answer in their own voice, even imperfectly, will always stand out over those who delegate their personality to a language model. We'll notice the difference.
