Data Engineer / Data Scientist

We’re looking for a Data Engineer / Data Scientist to join our team in a hybrid role that combines data infrastructure and modeling.

Requirements

• 2+ years of experience in data engineering, data science, or a closely related field.
• Proficiency in Python (Pandas, NumPy, or similar libraries); ability to read and ideally write TypeScript.
• Experience designing and working with relational databases (PostgreSQL) and time-series databases (InfluxDB or similar, such as TimescaleDB or ClickHouse).
• Experience building and maintaining REST APIs (data aggregation and serving layer).
• Familiarity with simulation systems, agent-based modeling, or scenario generation pipelines.

It Will Be a Significant Plus If You Have

• Experience working on fintech or blockchain projects.
• Familiarity with DSL design or structured data serialization formats (e.g., JSON Schema, Protobuf, Avro).
• Experience with Docker and multi-service orchestration setups.
• Understanding of financial data concepts (rates, balances, collateral, FX) — not required, but would significantly reduce onboarding time.

Responsibilities

• Own design and development of core data components within a complex distributed system, including defining data models, processing pipelines, and data flow between system parts.
• Collaborate with backend engineers to maintain backend services that aggregate, transform, and expose data through well-structured APIs for other services.
• Work with autonomous system components and their orchestration, ensuring reliable execution and data exchange.

Why Join Us?

• Work on cutting-edge AI/ML applications.
• Solve complex search and orchestration challenges.
• Opportunity to work with the latest LLM and AI search technologies.

We Offer

• Fully remote work and flexible working hours.
• Flexible time off whenever you need it.
• Investment in your professional and career growth, corresponding to wage growth.
• Mentoring and training.
• Opportunity to contribute to one of the functional programming industry’s leading blogs.
• Therapy sessions to support your well-being.
