• Integrate with third-party vendors and health tech innovations to expand our platform’s functionality, data sources, and member services
• Work on a member-facing platform and clinical intelligence platform used by our care teams to deliver efficient, quality care
• Own projects from ideation to release, influencing both product and technical decisions
• Contribute to technical architecture and best practices across the team

You’d Be a Good Fit If

• You love learning and unstructured problem-solving
• You enjoy and take ownership in designing, building, and shipping features end-to-end

At Intain, we fuse blockchain, analytics, and AI to power next-gen platforms for structured finance.

Join us to build on the cutting edge—smart-contract rails, real-time analytics, and AI-assisted workflows—all in one product stack.

What You’ll Do

• Own features end-to-end: design → code → test → deploy → iterate.
• Build modern web apps (React.js / Node.js, REST/GraphQL) that move real money.
• Automate quality with tests, CI/CD, and cloud (Azure).
• Use AI dev assistants to hit our “1 dev = 4 devs” productivity bar.

You Bring:

• Proven full-stack delivery in JS/TS (React + Node).
