We are a growing product team, and we’re looking for engineers who like working close to the product and are comfortable taking a feature from requirement to production.

Core Mandatory Priority (P0) — Data Structures & Algorithms (DSA)

Data Structures & Algorithms (DSA) is a strict P0 requirement for Tripare. Candidates must demonstrate deep algorithmic rigor, optimal time/space complexity analysis (Big-O), optimal data structure selection, and robust problem-solving alongside the core responsibilities under "What you’ll be doing" and "What we’re looking for".

About the role

This is a backend-heavy Full Stack role. Your work will be roughly 70% backend and 30% frontend. You’ll primarily work with Node.js, TypeScript and REST APIs, while also contributing to our React.js application. You’ll be involved in building new features as well as improving existing ones as the product scales.

What you’ll be doing

Build and maintain backend services using Node.js and TypeScript.
Develop REST APIs and the business logic behind different product features.
Implement secure API authentication and authorization, including role-based access controls.
Work with database designs and write efficient queries.
Design and evolve database schemas, migrations and indexes as product requirements change.
Integrate third-party APIs and services wherever required.
Build and operate asynchronous jobs, queues and background processing for reliable workflows.
Build and improve frontend features using React.js.
Fix bugs and production issues and understand the root cause rather than just applying quick fixes.
Review code and contribute to keeping the codebase clean and maintainable.
Work with product and engineering teams to understand requirements and decide the right technical approach.
Contribute to improving application performance and scalability.
Improve application observability through structured logging, metrics, tracing and actionable alerts.
Participate in deployments, debugging and day-to-day engineering discussions.
