What makes the Similarweb R&D team awesome?

  • We love data! At Similarweb you have the opportunity to work with it on a massive scale, processing huge volumes of data across a wide variety of global marketplaces.
  • We work with high‑load, highly dynamic environments, advanced bot‑protection mechanisms, and complex data pipelines running in Kubernetes.
  • Work with cutting edge technology - we often beta test the tech that other people will only discover next year!
  • We want you to get better and help you set goals and conquer them

 

Key Responsibilities:

  • Maintain, optimize, and modernize legacy monolithic systems during migration to microservices.
  • Design scalable backend solutions for high-frequency web crawling and data processing.
  • Optimize database performance for MongoDB (primary), PostgreSQL, and ClickHouse.
  • Collaborate with data teams to integrate pricing analytics and recommendation engines.
  • Ensure code quality via CI/CD pipelines, automated testing, and peer reviews.

Core Requirements:

  • 4+ years Java development (Core, multithreading, performance tuning).
  • Expert-level Spring Boot (RESTful APIs, JPA, security, batch processing).
  • Advanced SQL/NoSQL skills (schema design, query optimization, aggregation pipelines).
  • Hands-on Docker/docker-compose for containerization and local development.
  • Proficiency in Git/GitLab (branching strategies, code reviews, merge requests).
  • Python scripting for crawling (Scrapy), prototyping or automation tasks.
  • Fluent English (daily standups, technical docs, client-facing demos).

Critical Assets:

  • Experience decomposing monoliths (DDD, event-driven architecture, API gateways).
  • Familiarity with Kubernetes (cluster management, Helm charts, scaling).
  • Kafka/event streaming for real-time data pipelines (producers/consumers, connectors).
  • Monitoring tools (Prometheus/Grafana, ELK stack, error tracking).

Nice-to-Have:

  • Web crawling libraries (Jsoup, Selenium) or frameworks (Scrapy, Apache Nutch).
  • Understanding of proxy rotation, CAPTCHA bypass, and anti-scraping mechanisms.

We Offer:

  • Impactful role in a niche SaaS product serving enterprise-level clients.
  • Tech stack: Java 11+, Spring Boot, Kafka, GitLab CI/CD, Prometheus.
  • Competitive compensation.
  • Team culture prioritizing ownership, innovation, and upskilling.
