Senior Python Engineer - Visual Analytics Platform

🚀 Senior Python Engineer – Visual Analytics Platform

📍 Remote (anywhere in Lithuania)

⏳ 6-month rolling contract

💶 Up to €50/hour

We’re partnering with a leading systematic investment manager to build a next-generation visual analytics and diagnostics platform for a new multi-asset trading system. This platform will replace a legacy charting tool with a modern, federated, self-service solution used by quants, researchers, engineers, and operations teams.

The role

You’ll play a key role in architecting and building a Python-first analytics platform, designed to let users create rich, interactive dashboards without deep frontend expertise.

The platform is built using:

• Python (Reflex) as the primary development interface
• React.js under the hood, via shared design system components
• Highcharts for core visualisation
• Deployed internally onto a proprietary trading platform

What you’ll be doing

• Lead the architecture and technical design of the analytics platform
• Design and implement a Python-first visualisation and dashboard API
• Build scalable Reflex wrappers around React components
• Deliver core platform features: navigation, search, layouts, comparison views, permissions, and workspace integration
• Define and implement CI/CD, testing, and performance strategies
• Work closely with Quant Platform and Developer Platform teams
• Support other engineers and ensure knowledge transfer to internal teams

What we’re looking for

• Strong experience with Python in production systems
• Experience building data-heavy or analytics platforms
• Comfort designing scalable, testable systems
• Bonus: experience in trading, quant, or financial analytics environments

Why this role?

• High-impact work on a core trading analytics platform
• Modern tech stack with real architectural ownership
• Long-term potential via a rolling contract
• Fully remote from anywhere in Lithuania
