Також ти вестимеш R&D-роботи над agentic AI-архітектурами, подієво-орієнтованими системами та LLM-ready дата-пайплайнами — перетворюючи архітектурні концепції на готові до продакшену рішення.

Обовʼязки:

• Проєктувати та створювати масштабовані, хмарні дата-платформи від концепції до продакшену
• Реалізовувати пайплайни для майже реального часу (near-real-time ingestion) з використанням подієво-орієнтованих патернів

• Рефакторити та оптимізувати наявні скрипти на Spark та PySpark для підвищення продуктивності та зручності підтримки
• Запроваджувати найкращі практики якості коду, тестування та CI/CD для дата-пайплайнів
• Сприяти впровадженню AI-інструментів та agentic-підходів у команді дата-інженерів
• Забезпечувати якість, спостережуваність (observability) та надійність усіх пайплайнів і платформ

• Розробляти self-service інструменти та мікросервіси, що спрощують використання платформи іншими командами

   

Вимоги:

• 5+ років комерційного досвіду в Data Engineering
• Сильні навички розробки на Python та SQL для створення та оптимізації пайплайнів
• Впевнене володіння Apache Spark / PySpark, включно з оптимізацією запитів та налаштуванням продуктивності
• Практичний досвід роботи з Databricks (бажано) або Snowflake
• Досвід роботи з принаймні одним великим хмарним провайдером: Azure (бажано), AWS або GCP
• Досвід роботи з технологіями потокової обробки даних (Kafka, Spark Structured Streaming)
• Глибоке розуміння ETL/ELT-патернів, моделювання даних (dimensional, Data Vault) та побудови дата-складів
• Досвід роботи з інструментами оркестрації (Apache Airflow, Azure Data Factory або аналогами)
• Знання Infrastructure as Code (Terraform або аналогів)
• Розуміння вимог до продакшен-рішень: надійність, масштабованість, спостережуваність, продуктивність

• Рівень англійської — Upper-Intermediate

   

Буде плюсом:

• Знайомство з проєктуванням RAG-пайплайнів та патернами інтеграції LLM
• Знання фреймворків і інструментів для data governance (Unity Catalog, Apache Atlas або подібних)
• Досвід роботи з dbt для трансформації та моделювання даних

• Знайомство з MLflow, Feature Stores або інтеграцією з ML-платформами

   

Особистий профіль:

• Самомотивованість та проактивність у пошуку покращень
• Комфортна робота у швидкому та інноваційному середовищі
• Сильне аналітичне мислення та увага до деталей
• Відкритість до експериментів з новими технологіями та підходами

Requirements

• Strong knowledge of PHP (1+ year of hands-on experience) and Laravel framework (1+ year);

  Responsibilities

• Develop, maintain, and support company websites and web applications;
• Communicate with clients, clarify requirements, answer questions, and provide effective solutions;

• Collaborate with the team to improve product quality and performance.

   

  We offer an opportunity to grow professionally, work on interesting projects, and be part of a supportive and dynamic team.

We're looking for a smart QA engineer who can operate independently on a small remote team — flexing between manual, automation, and exploratory work as the situation calls for it, using AI tools to move faster.
 

What you'll do:

• Own QA across multiple projects — manual, automated, and exploratory
• Build and maintain automated test suites
• Catch the bugs developers miss — including the ones that aren't obvious from the ticket
• Work directly with developers from Jira tickets through to release
• Use AI tools (Claude Code) as a core part of your QA process — writing test cases, generating test data, analyzing failures, exploring edge cases, documenting bugs, and accelerating everything in between
   

Must-haves:

• Real QA experience — you've owned quality for a real product
• Comfortable with automation
• Self-starter — you figure out what to test, not wait for assignments
• Daily, hands-on use of AI tools — we'll ask you about your workflow
• Comfort working async in a remote team
• English proficiency
