• Take part in deployments, CI/CD, and monitoring alongside the team
• Write clean, tested, well-documented code and take part in code reviews

What You Bring

Proxy & Scraping Experience

• Around 2 years of hands-on production experience with proxy systems and web scraping
• Experience building and operating proxy-based or scraping infrastructure
• Practical understanding of IP rotation strategies, session persistence, fingerprinting, CAPTCHA/bot mitigation, and unblock flows

• Familiarity with networking fundamentals (DNS, TCP/IP) and request optimization
• Fluent English (documentation and communication are in English)

Mindset

• You thrive in fast-moving startups where ambiguity is normal and execution matters more than process
• You take ownership of your work, from design to delivery and quality
• You make sound decisions on your own and proactively improve systems
• Product-driven mindset: you care about user impact and business value, not just elegant code
• You spot risks and bottlenecks early and act on them
• Curious and practical about AI tools that make development faster

Why Join ProxyScrape

• Work on core products from the ground up
• High autonomy and real influence on the technical solutions you build
• Work directly with the CTO and a strong scraping lead
• Competitive compensation package
