We're looking for a Motion Designer to join our design team and take ownership of motion and video content for an iGaming/casino product: slot and bonus promos, social media clips, short ad videos, and animation of key visuals. When there's less motion work on your plate, you'll jump into static graphics — banners, SMM creatives, and adaptations for different formats and GEOs.This is a fast-paced, high-volume role: lots of short, quick tasks rather than weeks spent polishing a single video. If that pace suits you, and you love seeing your work go live within days — this is a great fit, and we'd love to hear from you.

What you'll be doing: 

• Motion and video for slot and bonus promos, SMM clips, short ad videos
• Animation of key visuals

• AI tools: generation/variations/upscaling plus manual refinement of the result
   

Technical tools

• Adobe After EffectsAdobe 
• Photoshop + Figma
• Premiere Pro or CapCut
• AI tools: Kling, Seedance, or alternatives
   

🌟 Nice to have:
Graphic design skills — the ability to work with static graphics (website banners, SMM creatives, promo materials) and pick up these tasks during downtime or when motion work isn't filling your full workload

What We Offer:

• 24 days of vacation + days off
• Remote-first — work from anywhere in the world
• Support for your learning and professional development through external courses and educational activities (conferences, webinars, etc.)
• Benefits cafeteria: a flexible budget you can spend on sports activities, English language courses, and more
• No test assignment — we assess your experience through a live conversation
• Probationary period: 3 months, with clear and straightforward expectations from day one
   

Hiring Process:
Transparent and streamlined selection process: screening call (~40 min) → technical interview (50 min) → job offer

✦ Flexibility to navigate different project types and collaborate across multiple product teams simultaneously
 

Nice to have

✦ GTM (Go-To-Market) experience

✦ Experience in design-heavy projects or creative direction workflows

✦ Background in outstaffing or agency environments

What we offer:
✦ 8-hour working day
✦ 21 days of paid vacation
✦ 14 days of paid sick leave
✦ Unlimited days off
✦ Compensation for professional and English courses

ABOUT THE CLIENT

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

ABOUT THE ROLE

We are looking for a Middle-level SDET to design and maintain automated tests for a large-scale distributed data platform. You will validate the correctness, performance, and reliability of the query engine, connectivity layer, and backend services across all major clouds.

This is a data-heavy, backend-focused role. We are not looking for web/UI QA engineers — the work centers on validating distributed query execution, data correctness at scale, connectivity drivers, and backend microservices.

RESPONSIBILITIES

• Develop and maintain automated tests in Python / pytest for backend services, REST APIs, and distributed data components.
• Write end-to-end, integration, and regression tests covering SQL query execution, data correctness, and platform APIs.
• Support performance and load testing with JMeter, including workloads over JDBC / ODBC / Arrow Flightdrivers.
• Validate data-intensive scenarios — query plans, result correctness across data sources, metadata consistency, and behavior under concurrency.
• Contribute to CI/CD test pipelines in Jenkins — configure, maintain, and troubleshoot.
• Provision and manage test environments in Kubernetes (GKE / EKS / AKS) across GCP, AWS, and Azure using Docker.
• Investigate failures across the stack — query engine, distributed services, drivers, infrastructure — and drive them to resolution with engineering.
• Collaborate with US-based developers on testability and quality gates.

REQUIRED QUALIFICATIONS

• Education: B.S. or M.S. in Computer Science, Computer Engineering, or a related technical field.
• Programming: Strong proficiency in Python, including pytest, with a solid grasp of OOP and software design principles.
• SQL & Data: Strong SQL skills and solid understanding of how relational and analytical data systems work.
• Data-intensive testing experience: Hands-on experience testing data-intensive systems — query engines, ETL/ELT pipelines, streaming platforms, or analytical databases. Candidates with only web/UI QA backgrounds are not a fit.
• Testing experience: 3+ years in backend/system test automation or SDET roles.
• CI/CD & DevOps basics: Practical experience with Jenkins pipelines and deploying/maintaining test environments.
• Containers: Working knowledge of Docker and basic Kubernetes (running workloads, debugging pods, kubectl fluency).
• Cloud: Comfortable operating in at least one major cloud (GCP, AWS, or Azure).
• Version Control: Confident with Git / GitHub workflows.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.

DESIRED SKILLS

• Experience testing REST APIs and backend microservices at scale.
• Familiarity with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines(e.g., Presto, Trino, or similar).
• Understanding of modern data lakehouse concepts, open table formats (Apache Iceberg), and data warehousing.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.
• Performance testing with JMeter or comparable load-testing tools.
• Kubernetes on managed services (GKE / EKS / AKS) and multi-cloud exposure.
• IaC tools such as Terraform.
• Understanding of query plan generation, query acceleration / materializations, and metadata integrity in distributed data systems.
• Please note: We can consider only candidates currently residing in the EU, EEA, or the UK
