• Build bidirectional integrations with finance and procurement platforms using RESTful APIs and event-driven architectural patterns.

• Collaborate directly with Product and Architecture leads to translate complex requirements into scalable CI/CD production deliverables.

What You'll Need

• 4+ years of professional Full Stack development experience with a strong portfolio in Python, Node.js, and React.

• Deep expertise in SQL and relational databases; hands-on experience with cloud data warehouses and data transformation frameworks is a major plus.

• Proven experience building and consuming RESTful APIs within large-scale, enterprise-level ecosystems.

• Familiarity with workflow orchestration concepts, prompt engineering, or LLM-based system design.

• A Bachelor’s degree in Computer Science or Software Engineering and a "builder’s mindset" for early-stage product environments.
