Key Responsibilities

  • Deep-dive analysis of third-party client-side web solutions — tracing API flows, auth sequences, and performance hotspots.
  • Design, build, and maintain high-throughput Node.js middleware that routes external web traffic through internal services.
  • Develop and occasionally extend companion React 18 single-page apps (dashboards, simulators, internal tools).
  • Work in a fully agile environment (Scrum) alongside senior engineers, product managers, and security specialists.
  • Manage service dependencies, versioning, and CI/CD pipelines (GitLab CI, Docker, Open API, SSE).
  • Participate in code reviews, backlog grooming, retrospectives, and continuous product-quality improvement.
  • Write and maintain unit, component, and e2e tests; ensure full-cycle feature delivery — estimation, decomposition, implementation, release.

Required Experience

  • 5+ years of production experience with JavaScript (ES6+) and TypeScript on Node.js, deep understanding of vanilla JavaScript.
  • Solid understanding of modern browser internals: page lifecycle, DOM & JS runtime, resource loading (HTTP/2, QUIC, CORS, CSP, Service Workers, WebSockets).
  • Hands-on experience analysing or reverse-engineering web front-ends: reading minified / obfuscated code, reproducing business logic, inspecting network traces.
  • Proficiency with proxy / MITM tooling (mitmproxy, Charles, Burp Suite) or programmatic interception libraries (http-proxy, undici hooks).
  • Strong grasp of networking fundamentals (TCP/IP, TLS, DNS, SOCKS/HTTP proxying) and traffic encryption concepts.
  • Solid understanding of HTML5 / CSS3 and responsive UI patterns.
  • Familiarity with webpack, Babel, Docker, GitLab CI, GitLab package registry, semantic versioning, and Open API specs.
  • Ability to write clean, testable code and corresponding unit tests.
  • Good UX sensibility and attention to performance and accessibility.
  • Confident Git workflow, code reviews, and team development habits.
  • Strong knowledge in website vulnerability analysis.
  • Fluent Russian speaker; English proficiency at B1+ level.

Nice to Have

  • Proficiency with Nginx (reverse-proxy, load balancing, caching).
  • Experience designing or auditing high-load network services (10k+ RPS).
  • Familiarity with WebAssembly, static-analysis tooling (webpack-bundle-analyzer, source-map-explorer).
  • Experience with cloud providers (AWS, GCP, etc) and their load-balancing stacks.
  • Practical skills with React 18 and state management (Redux-Saga).
