Senior Full Stack Developer / Application Lead

Experience: 6–9 years Location: Bangalore (in-office) Stack: React 19, TypeScript, Java 17, Spring Boot, PostgreSQL, Python/FastAPI Reports to: CTO
About the Role
Zenalyst builds an enterprise agentic execution layer for the CFO's office — treasury, procure-to-pay and collections automation for large organisations.
We are looking for someone to own the application layer end to end. That means the React SPA, the Java backend gateway, the data model underneath, and the boundary where our Python agent runtime meets customer financial data. You will be the person who knows how a feature actually works from browser to database, and the person a junior engineer asks when they are stuck.
This is a hands-on lead role. You will write code most days. You will also review it, break down work, set standards, and be accountable for what ships.
Responsibilities
Technical ownership
Own the application layer across frontend, backend and data model
Make and document architecture decisions within the application layer, in consultation with the CTO




Own the multi-tenant boundary in practice — physical database per tenant, connection selected from verified JWT principal, no tenant identifier ever accepted from a request body
Own the contract between the Java backend gateway and the Python agent runtime; this is the single exit path to customer data and it stays that way
Design and evolve PostgreSQL schemas for treasury domain objects; own migration strategy across tenant databases
Set and hold the standard for correctness in flows that touch money — idempotency, reconciliation, partial failure, audit
Delivery
Break down product requirements into technical work and sequence it
Estimate honestly, flag risk early, and be accountable for delivery dates
Run code review; be the last line of defence before production
Own release quality — testing strategy, staging validation, rollback plans
Team
Lead a small team of 3–6 engineers day to day: assi
