To support this mission, we're looking for a Senior Backend Engineer to work on proxy infrastructure and unblocking.
Anti-bot systems are constantly evolving, and we need to keep our scraping infrastructure ahead of them. You'll expand Apify Proxy, research anti-scraping services, and build internal tools that use browser fingerprinting, human-like interactions, and session management to keep data flowing.
If you enjoy solving hard technical problems and contributing to open-source proxy libraries, this role might be for you.
WHAT YOU'LL BE WORKING ON:
- Building robots that behave and act like real users to automate human activities on the web
- Working in a small cross-functional team with other experienced hackers
- Expanding the capabilities of Apify Proxy, adding more protocols and more underlying providers, and implementing internal unblocking capabilities
- Researching existing anti-scraping services and implementing new internal services to overcome them by utilizing various browser fingerprinting methods, human-like browser interaction, session management, and others
- Contributing to proxy-chain https://github.com/apify/proxy-chain and impit https://github.com/apify/impit, our open-source libraries for proxy handling and request impersonation

- Monitoring: Grafana, Prometheus, OpenTelemetry, Mezmo, Sentry, PagerDuty
- Frontend: React.js, styled-components, Storybook, Chromatic, Cypress, Playwright
- Backend: TypeScript/Node.js, Nest.js, Next.js, Docusaurus, Vitest
- Tools: GitHub, Notion, Google Workspace, Slack
- OS, code editor, and AI assistant of your choice (Claude premium with unlimited tokens, GH Copilot, Cursor, Gemini, or JetBrains AI)
- Process: two-week sprints, code reviews, tests, automating whatever we can, and deploying multiple times per day.
WHO WE’RE LOOKING FOR:
- A strong technical background or great professional track record (we're looking for exceptional candidates, no matter the seniority)
- 2+ years of industry experience building proxy, fingerprinting, or unblocking services
- Strong skills in developing and debugging with TypeScript/Node.js, or equivalent skills in another language and the ability to learn quickly
- Familiarity with Linux
- Experience with AWS, other public clouds, or any technology mentioned above (nice to have)
- An experiment-driven and collaborative mindset
- Good communication skills in English
WHY SHOULD YOU WORK AT APIFY?
- Space, support, and autonomy for personal growth, with a direct impact on Apify's success
- Full-time position in Prague (Lucerna Palace) or Brno (Titanium) 🏰
- Option to work remotely 🛋️
- Flexible working hours (perfect for both night owls 🦉 and early birds 🐥)
- Nobody counts holidays as long as the work gets done 💪
- Unlimited Claude for every Apifier. We don't count tokens. Just use them well 🤖
- Stock options and profit sharing 💰
- We welcome pets, kids, and bikes at the office 🐕👨👧
- Epic team buildings and offsites 🚢 with biking, canoeing, and other adventures 🪂
- Solid education and training budget, conference tickets, internal “Eat & Learn” sessions, and the possibility to work across teams 👩🏼💻👨🏽💻
