• Actively leverage AI-driven development tools (e.g., Claude, Cursor, agentic workflows) in daily work

Required Competence and Skills:

• 8+ years of professional software development experience with Ruby on Rails. If your main specialization is  Python, or Java, then readiness to work extensively in Ruby is expected.
• 4+ years of front-end development in VanillaJS (or React, or Vue, or equivalent frameworks), CSS (including animations), and HTML.
• Experience developing embeddable widgets and integrating them into customer websites.
• Proven track record in performance optimization, Core Web Vitals, and front-end tooling.
• Strong understanding of end-to-end system design, cloud environments (preferably AWS), and CI/CD pipelines.
• Experience building and maintaining large-scale systems under high throughput.
• Familiarity with AI-driven development workflows, including prompt engineering and automated testing.

Nice to Have:

• Experience in content monetization and ad-tech integrations.

• Hands-on experience with cloud infrastructure and serverless deployments.

Why Us:

We provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).

We provide full accounting and legal support in all countries we operate.

Geo-Spatial & Time-Series Expertise: Proven, hands-on experience handling massive datasets specifically involving geo-spatial (GIS) data, audience attributes, and high-frequency time-series data.
 

Advanced Software Engineering (Python): Mastery of Python beyond standard data scripting. You write highly modular, object-oriented code. You have deep, practical experience with Test-Driven Development (TDD), mocking, exception handling, and performance profiling, functional programming.
 

Architectural Vision: Deep expertise in designing scalable data architectures using both relational and horizontally scalable data warehouses/lakehouses (e.g., Snowflake, Redshift, Athena, StarRocks, Iceberg). You deeply understand query execution plans, partitioning, clustering, and cloud cost governance.
 

Big Data Frameworks: Extensive experience with large-scale data processing frameworks (e.g., Apache Spark, PySpark, AWS EMR, Glue) to handle massive throughput.
 

Expert SQL & dbt: You design scalable, robust data models (using Jinja, macros, incremental strategies) that serve as the foundation for our entire analytics layer.
 

AWS Cloud Native & IaC: Hands-on experience building architectures in AWS (e.g.: AWS Lambda, AWS Batch, Glue, StepFunctions, S3, EC2, ECS, ECR, Fargate) and deploying them using Infrastructure as Code (Terraform).
 

Leadership Skills: Superb organizational and communication skills. You can distill complex architectural trade-offs for non-technical stakeholders and drive technical consensus among your engineering peers.
