Documentation & Technical Coordination
-Prepare detailed integration documentation, including technical specifications, endpoint mappings, and functional requirements.
-Create and manage PRDs and technical tasks for development teams, ensuring accurate implementation of payment logic and validations.
-Maintain backlog items and coordinate integration requirements across teams.

Testing & Delivery
-Participate in integration testing and validation together with Operations and technical teams before production release.
-Monitor integration performance and support updates when provider APIs or schemas change.

Requirements
-Strong experience working with APIs, including testing tools such as Postman or Insomnia.
-Ability to analyze Swagger/OpenAPI documentation and understand complex API structures.
-Experience designing system flows and sequence diagrams using tools like Lucidchart, Miro, or Mermaid.
-Solid knowledge of JSON and XML data structures and field mapping between systems.
-Understanding of payment technologies, including webhooks, callbacks, and real-time transaction processing.
-Experience working with Jira, Confluence, or similar tools for documentation and backlog management.
-Good understanding of authentication and security standards such as OAuth, JWT, and API Keys.

Ми будуємо власний CDN Edge сервер (ccdn-edged) — високопродуктивний демон на Go, що обробляє живий трафік через HTTP/1.1, HTTP/2 та HTTP/3 (QUIC). Це не черговий REST API. Це системне програмування: реверс-проксі, мережевий стек, оптимізація затримок, WAF, in-memory кешування і Edge Functions.

Шукаємо інженера, який розуміє як насправді працює HTTP, знає різницю між goroutine scheduler і OS thread, і якому цікаво копатись у кишках мережевих систем.

Технологічний стек

Мережевий шар:

    •    HTTP/1.1 & HTTP/2 — stdlib
    •    HTTP/3 / QUIC — quic-go
    •    Reverse Proxy — httputil + fasthttp
    •    TLS Fingerprinting

Безпека:

    •    Coraza WAF — інспекція трафіку
    •    TLS Client Identification
    •    Rate Limiting / Bot Detection

Стан та кеш:

    •    Redis — конфігурація зон, хостів, сертифікатів
    •    In-memory кеш об’єктів

Observability:

    •    VictoriaMetrics / Prometheus
    •    zerolog — structured logging
    •    Access logs via Unix-сокети
    •    Goja — JS Edge Functions (ES5.1+)

Середовище: Go 1.26, GOEXPERIMENT=jsonv2,greenteagc,synchashtriemap

Що обов’язково знати:

    •    Go 3+ роки в продакшені — goroutines, channels, sync primitives, memory model
    •    Глибоке розуміння HTTP/1.1, HTTP/2 (framing, multiplexing, flow control)
    •    Досвід написання реверс-проксі або мережевих серверів / клієнтів
    •    Розуміння TLS — handshake, certificates, ALPN, SNI
    •    Профілювання Go: pprof, trace, heap / goroutine dumps
    •    Робота з low-latency системами — буфери, zero-copy, escape analysis
    •    Redis: структури даних, pub/sub, pipeline

Буде плюсом:

    •    Знайомство з QUIC / HTTP/3 (RFC 9000, 9114)
    •    Досвід із fasthttp або іншими high-perf HTTP бібліотеками
    •    Розуміння WAF / ModSecurity rule engine
    •    Embedded JS runtime (Goja / V8 / QuickJS)
    •    Знайомство з VictoriaMetrics або Prometheus internals
    •    Досвід у CDN, DDoS-захист або edge computing

Важливо

Ця роль не підходить тим, хто спеціалізується виключно на REST API або бізнес-логіці. Тут потрібно розуміти, що відбувається на рівні TCP-з’єднання, як передаються фрейми HTTP/2 і чому zero-copy важливий для пропускної здатності. Якщо тебе цікавить «як все влаштовано зсередині» — ти потрібен нам.

Що ти будеш робити

    Розробляти та підтримувати ядро CDN Edge демона (ccdn-edged)
    •    Оптимізувати проксування трафіку — затримки, throughput, з’єднання
    •    Інтегрувати та налаштовувати WAF (Coraza) під реальний трафік
    •    Розвивати Edge Functions runtime на базі Goja
    •    Проектувати схеми кешування (L1 in-memory + L2 Redis)
    •    Писати benchmark-тести та профілювати критичні шляхи
    •    Брати участь у code review та архітектурних рішеннях

Умови роботи

    •    Повна зайнятість, Remote або Relocate
    •    Конкурентна зарплата — обговорюється на інтерв’ю
    •    Технічне завдання замість leetcode-тестів
    •    Невелика команда, прямий вплив на архітектуру
    •    Сучасний стек без legacy-обмежень
    •    Реальний high-load трафік з першого дня
