About AppsFlyer (Kyiv):

AppsFlyer provides a SaaS marketing analytics platform that measures and optimizes marketing activities across mobile, web, CTV, PC, and console applications. AppsFlyer is known for its massive backend production. At any given moment, thousands of servers are consuming 150+ billion mobile app events, crunching our users’ data, serving requests, and communicating on a massive scale.

To maintain the universe we call AppsFlyer, we practice modern production operations with a complete self-serve CI/CD platform, a highly integrated observability stack for our micro-services, backends, and infrastructure, a culture of ownership and eagerness for quality.

The Analytics group is responsible for showing our clients the stories their data is telling. Through complex aggregation, mission-tailored analytical databases, and carefully crafted APIs we are able to provide slice-and-dice analysis in our beautiful dashboards and through the use of external integrations.

About the Role:

As a Data Engineer in AppsFlyer’s Analytics group, you will be responsible for the full lifecycle of event data — from ingestion and processing to storage, modeling, and delivery through APIs.

You will build and maintain data pipelines with Apache Airflow and Spark, evaluate and optimize analytical databases, and integrate new components within a hybrid microservices architecture. You will work closely with product managers and cross-functional engineering teams, handle production issues, and take part in the company’s migration toward Google Cloud and BigQuery.

This role provides a high level of ownership over feature design, direct impact on a platform processing billions of events every day, and opportunities to contribute to open-source initiatives or share expertise at industry events.
 

Key Responsibilities:

• Develop and support data processing pipelines using Apache Airflow, Scala Spark, or PySpark.
• Select, design, and optimize analytical databases for high-volume, low-latency queries.
• Build backend services and APIs for data ingestion, aggregation, and customer-facing data consumption.
• Monitor system reliability and performance, investigate issues, and resolve production incidents.
• Partner with product managers and engineering teams to plan, design, and deliver complex features.
• Support migration initiatives to Google Cloud Platform, BigQuery, and modern data technologies.
• Participate in on-call rotations, PagerDuty alerts, and incident response processes.
• Document architecture, data flows, and technical decisions while maintaining high code quality and test coverage.
   

Required Competence and Skills:

• 3+ years of software development experience with a strong focus on data engineering.
• Hands-on experience with Apache Spark, using either Scala or PySpark.
• Practical experience with Apache Airflow.
• Background in building and maintaining distributed data systems with high throughput and low latency.
• Strong SQL knowledge and experience with data modeling for analytical use cases.
• Experience with JVM-based languages such as Scala, Java, or Clojure, or Python for backend development.
• Experience with cloud platforms, preferably GCP, and data warehouses such as BigQuery.
• Proven ownership of production systems, including on-call responsibilities and incident management.
• Strong English communication skills for working in a distributed environment.
• B.Sc. in Computer Science or equivalent practical experience.
   

Nice to Have:

• Production experience with large-scale databases and ETL tools.
• Hands-on experience with backend services written in Go or Clojure.
• Experience building production-grade BigQuery ETL processes and data pipelines.
• Contributions to open-source projects or experience speaking at meetups, conferences, or industry events.
• An AI-oriented mindset, including familiarity with tools such as GitHub Copilot and modern AI-assisted workflows.
  
  Benefits Package:
• Health insurance.
• Paid unlimited vacation days, national holidays, and additional recharge days.
• Meal reimbursement.
• Sport reimbursement.
• Breakfast in the office.
• Mental health program.

Performance Motion Designer
 

Who we are:

Adaptiq is a technology hub that builds, scales, and supports R&D teams for fast-growing product companies across different industries.
 

About the Product:

We are working with an AI-native performance marketing platform focused on producing and scaling paid social and affiliate creatives across competitive and regulated markets.

The platform covers the full creative lifecycle: from brief analysis and audience research to concept generation, AI-assisted production, media buying, performance tracking, and continuous creative optimization. It helps teams create and test UGC-style videos, short-form ads, and motion creatives faster, while feeding real campaign data back into the production process.

The product supports over $100M in annual managed ad spend and is used across several verticals, including health and wellness, e-commerce, finance, mobile apps, and digital services. Since many of these areas are regulated, the team also works with strict requirements around brand compliance, privacy, and messaging accuracy.
 

About the Role:

As a Performance Motion Designer, you will be responsible for creating high-volume video and motion creatives for performance campaigns. You will work closely with creative strategists and media buyers to turn briefs, audience insights, and campaign results into engaging short-form assets for modern paid social channels.

The main focus of the role is not only to make visually strong videos, but to create creatives that perform. Success will be measured through metrics such as hook rate, retention, CTR, and conversion. You will test ideas quickly, analyze what works, iterate on winning concepts, and build multiple creative variations in fast feedback cycles.

This role is a good fit for someone who is comfortable working independently, actively uses AI tools in production, follows new creative technologies, and enjoys combining motion design, editing, performance marketing, and data-driven experimentation.

Key Responsibilities:
 

• Create high-volume video and motion assets for paid social campaigns, including UGC-style ads, short-form videos, advertorials, and native content.
• Develop strong hooks and clear value delivery within the first 1–3 seconds of each video.
• Optimize creatives for sound-off viewing and fast-scrolling social media environments.
• Prepare assets in different formats and placements, including 9:16, 4:5, 1:1, and 16:9.
• Use AI tools and internal production workflows for video, image, voice/audio generation, and editing.
• Turn successful concepts into multiple creative variations and quickly adjust underperforming ideas.
• Edit and animate 2D elements, characters, graphics, and motion components to support the message and pacing.
• Apply strong composition, pacing, storytelling, and cinematic principles to improve retention and emotional impact.
• Collaborate with creative strategists and media buyers to translate briefs and performance insights into better-performing assets.
• Maintain quality, consistency, and compliance across different brands, clients, and regulated verticals.

Required Competence and Skills:
 

• 4+ years of experience in video editing or motion design, preferably in performance marketing, paid social, DTC, or similar environments.
• Strong practical experience with AI creative tools, including:
  • video generation tools such as Runway, Kling, Sora, Higgsfield, Veo, or similar;
  • image generation tools such as Midjourney, Nano Banana, Seedream, or similar;
  • voice/audio tools such as ElevenLabs;
  • AI-assisted editing tools such as CapCut, Descript, Adobe Firefly, or similar.
     
• Expert-level skills in Adobe After Effects and Premiere Pro.
• Strong working knowledge of Photoshop.
• Strong written and spoken English for daily collaboration.
• Performance-oriented creative mindset, with focus on hook rate, hold rate, CTR, and conversion rather than only visual polish.
• Good understanding of what performs well on Meta, TikTok, and other short-form paid social platforms.
• Ability to quickly learn new tools, test new workflows, and integrate them into daily production.
• Strong collaboration skills and ability to work in a fast-paced, high-output environment with frequent feedback.
   

Nice to Have:

• Experience with 3D animation or modeling.
• Experience creating ads for regulated verticals such as telehealth, wellness, or finance.
• Understanding of affiliate marketing, performance networks, or media buying principles.
   

Why Us:

• 20 working days of vacation per calendar year, plus official national holidays in your country of residence.
• Full accounting and legal support in the countries where we operate.
• Fully remote work model, with a powerful workstation and access to co-working space if needed.
• Competitive compensation package with annual performance and salary reviews.
