Sr. Full - Stack Engineer

We are hiring a Senior Full-stack Engineer to build across that platform. Most of the work comes down to getting numbers right. Interest, payment allocation, default premiums, and payoff figures all have to agree with each other across the schedule, the ledger, and the screen a lender is looking at. A one-cent difference is a bug we go and find. You will work in TypeScript across the stack: Postgres and Prisma, Express services, Next.js and React, and on our AI Advisor, which answers questions about a lender's portfolio in plain language.

Responsibilities:

• Build features end-to-end: schema, data access, services and business rules, API, React UI, tests, and deployment.
• Extend the lending engine with new loan products, schedule types, fee structures, lifecycle transitions, and reporting.
• Keep every surface in agreement. One payment moves several parts of the system, and they all have to say the same thing afterwards.
• Build AI features on top of live loan data, including the guardrails that make an answer safe to put in front of a lender.
• Write and maintain tests. Correctness here is enforced by the test suite, not by hoping.
• Review code, ship to production, watch it, and fix it when it breaks.
• Work directly with the founder and with lenders using the product.

Requirements:

• 4+ years of non-internship professional software development experience.
• 2+ years of backend development with Node.js, or another server-side language, with willingness to work in Node.js .
• 2+ years of frontend development with React, or a comparable modern JavaScript framework.
• 2+ years of professional TypeScript.
• 2+ years working with a relational database, including schema design, migrations, transactions, and query performance.
• Experience designing and building web services and APIs.
• Experience using AI tools in day-to-day development and the judgment to check and correct what they produce.
• Comfortable working asynchronously across a wide time-zone gap, with a few scheduled calls each week outside standard IST hours.
• Bachelor's degree in computer science, engineering, mathematics, or a related field, or equivalent practical experience.

Preferred Qualification:

• Experience in lending, payments, accounting, or another domain where the numbers have to reconcile.
• Experience shipping features backed by large language models: prompt design, tool calling, streaming, evaluation, and guardrails.
• Experience with Next.js App Router, React Server Components, and Prisma.
• Experience writing end-to-end or browser-based tests.
• Experience owning CI/CD pipelines and production monitoring.
• Experience building a product that ships in more than one language.
• Experience mentoring engineers.
• Experience at an early-stage startup, working directly with customers.
