If you’re a creative problem-solver who thrives on reverse-engineering challenges, building scalable microservices, and working across the full stack, this role is for you.

Profile Overview

Your immediate impact in the first 3-6 months will be:

• Become a core member of our newly formed development team
• Design and build a cutting-edge, scalable browser automation scraper from the ground up
• Reverse-engineer web protocols and bypass anti-scraping mechanisms (CAPTCHAs, rate limits, fingerprinting)
• Optimize scraping infrastructure for speed, reliability, and stealth
• Contribute to the development of microservices APIs, and other backend systems when scraping tasks are not a priority. 

Your responsibilities

• Architect and develop high-performance scrapers using tools like Playwright
• Implement proxy rotation, request throttling, and CAPTCHA-solving strategies
• Continuously monitor and adapt to evolving website structures and defenses
• Ensure data accuracy and compliance with legal/ethical scraping practices
• Design, build, and maintain scalable microservices and APIs using modern backend frameworks
• Collaborate on frontend development using Vue.js when needed
• Mentor teammates on best practices for scraping, backend development, and full-stack engineering

What You bring to the table

• 5+ years of backend development experience, with 2+ years dedicated to web scraping or architecting and building highly scalable solutions for data-intensive applications
• Expertise in Node.js (TypeScript), distributed systems frameworks, and cloud-native microservices architectures
• Experience in designing and optimizing high-throughput data processing pipelines, asynchronous messaging systems, and resilient data ingestion frameworks
• Strong understanding of OLAP databases like ClickHouse for analytical workloads, complemented by proficiency in scalable storage and query optimization
• A “detective mindset” – you enjoy dissecting complex systems and inventing unconventional solutions
• Senior-level ownership: You plan meticulously, document thoroughly, and proactively mitigate risks

What’s in it for You

• Ultimate flexibility: We’re 100% remote. You can work from wherever you like, whenever you like.
• Freedom and autonomy: We’re a high-trust team, and you’ll be given lots of flexibility to solve problems in your own way — with plenty of help from the team when you need it.
• Minimum bureaucracy: We don’t like to get bogged down with meetings and red tape. We like to be efficient and keep momentum steady & sustainable.
• Small & friendly team: We help each other out, have fun, and joke around.
