Collaborate closely with Product, Design, and Engineering to deliver high-impact features
Participate in sprint planning, estimation, stand-ups, and retrospectives
Write clean, maintainable, and well-tested code
Debug and resolve production issues with a focus on reliability and user experience

What You’ll Bring

5+ years of full-stack engineering experience
Strong experience with Python and/or C# in production environments
Experience integrating and working with third-party APIs (REST, webhooks, SDKs, etc.)
Strong experience with modern frontend frameworks (React preferred)
Solid backend experience with Node.js, TypeScript, or similar languages

Familiarity with relational and/or NoSQL databases (PostgreSQL, Redis, etc.)

Nice to Have

Experience building data-heavy or analytics-driven applications
Exposure to financial systems, trading platforms, or fintech products
Experience with event-driven architectures or messaging systems (Kafka, etc.)
Familiarity with Electron or desktop applications
Experience deploying applications using cloud platforms (AWS, GCP, Azure)
