Hiring: Senior Full Stack Engineer — Java | React | Python

About the Role

We are looking for a Senior Full Stack Engineer with deep expertise in Java, React, and Python to design, build, and scale mission-critical systems end-to-end.

You'll own features from architecture through production, collaborate closely with product and data teams, and drive engineering excellence across distributed systems, async pipelines, and contemporary frontend surfaces.

What You'll Do

Backend & Distributed Systems

- Design and deliver high-throughput Java (Spring Boot) microservices handling hundreds of concurrent RPS under sustained peak load.
- Build secure, production-grade RESTful APIs and async processing pipelines with full end-to-end ownership.
- Develop Python (FastAPI) microservices for data ingestion, ETL orchestration, and ML/AI-adjacent workflows.
- Architect event-driven systems using Apache Kafka, Redis, and async frameworks for real-time data processing.
- Scale services on GCP (GKE) and AWS (EKS, Lambda, S3) with observability and load-tested rollout strategies.
- Lead microservice modernization — decompose monoliths, define API contracts, and own delivery to production.

Frontend & UI

- Build performant React.js applications with Type Script, Redux Toolkit, Tan Stack Query, and Next.js.
- Architect micro-frontend platforms using Webpack Module Federation and event bus patterns.
- Develop real-time UI surfaces (Web Socket-driven dashboards) with sub-second update cycles.
- Design Dynamic UI Engines — configurable forms driven by backend JSON metadata — enabling low-code configurability.

Data & Databases

- Design PostgreSQL schemas optimized for high-volume transactional and analytical workloads.
- Build Big Query / Snowflake pipelines — views, streams, tasks,



stored procedures — for large-scale KPI analytics.
- Optimize query performance and implement advanced caching to reduce backend load.

Dev Ops & Observability

- Containerize and deploy via Docker, Kubernetes (GKE/EKS), and Helm with blue/green rollouts.
- Build observability dashboards with Kibana, Elasticsearch, Grafana for system health monitoring.
- Conduct load testing (Locust, custom harnesses) and GKE tuning for production readiness.

What We're Looking For

Must-Have

- 5+ years of full stack engineering with end-to-end ownership.
- Strong proficiency in Java (Spring Boot) — microservices, REST APIs, async processing.
- Solid Python backend experience — FastAPI, asyncio, Kafka integration, ETL pipelines.
- Production-grade React.js — Type Script, hooks, Redux, Tan Stack Query.
- Deep understanding of distributed systems — Kafka, Redis, event-driven architecture.
- Hands-on PostgreSQL — schema design, query optimization, transactional workflows.
- Cloud experience on GCP or AWS — containerized deployments, managed services.
- Strong system design instincts — HLD docs, API contracts, stakeholder alignment.

Nice-to-Have

- Big Query, Snowflake, or Databricks for analytics pipelines.
- Micro-frontend architecture (Webpack Module Federation).
- Compliance/fintech domain experience (AML, KYC, PCI-DSS).
- AI/LLM-augmented development workflows.
