Original source description
The ideal candidate will possess strong expertise across frontend, backend, database engineering, cloud infrastructure, and modern engineering practices. We are seeking a highly skilled Senior Full Stack Engineer to design, develop, and scale mission-critical fintech products that support treasury operations, payment processing, financial automation, and enterprise transaction management. They will play a key role in building secure, highly available, and compliant financial systems while mentoring engineers and driving engineering excellence across the organization. Key Responsibilities: Infrastructure & DevOps: Terraform & Kubernetes Fintech applications handle sensitive corporate funds and must maintain strict uptime and disaster recovery standards. Infrastructure as Code (Terraform): Provisioning cloud infrastructure (AWS/GCP/Azure) reproducibly and securely, ensuring network isolation (VPCs, private subnets for databases). Orchestration (Kubernetes): Managing deployments, ingress controllers, horizontal pod autoscaling, and secrets management. Containerization (Docker): Writing multi-stage, secure, and minimal Dockerfiles for Java and Node.js applications. AI-Assisted Development & Engineering Workflow: Critical Code Review: Acting as the final editor for AI-generated code—checking specifically for edge cases, performance bottlenecks, and subtle security vulnerabilities (like SQL injection or insecure direct object references). Prompt Engineering for Code: Using AI tools (like GitHub Copilot or Claude) effectively to write unit tests, boilerplate DTOs, and documentation. Accelerating delivery while maintaining code health. Backend: Java Spring & Microservices Core banking, payment switching, and ledger systems demand robust, strongly typed enterprise backends. Spring Boot & Spring Cloud: Building modular RESTful APIs and event-driven microservices. Concurrency & Transactions: Understanding ACID properties, distributed transactions (Saga pattern or two-phase commits), and handling race conditions in concurrent fund transfers. Security & Compliance: Deep familiarity with Spring Security, OAuth2, JWT, and implementation of role-based access control (RBAC). In fintech, auditing logs and tracking request lifecycles are non-negotiable. Database: PostgreSQL Financial data requires strict consistency, complex relational modeling, and performance tuning. Data Integrity & Constraints: Utilizing foreign keys, check constraints, and custom Postgres types (like Enums for transaction statuses). Indexing & Partitioning: Managing large-scale transaction logs through strategic index planning and table partitioning by date ranges. Advanced SQL: Writing optimized queries, window functions, and Common Table Expressions (CTEs) for financial reporting and ledger reconciliation. Frontend Engineering: React & Next.js Fintech dashboards require heavy data visualization, real-time tracking, and absolute interface reliability. State Management & Data Fetching: Mastery of tools like TanStack Query (React Query) or Redux Toolkit for handling asynchronous financial data, caching, and serverstate synchronization. Server-Side Rendering (SSR): Leveraging Next.js for performance optimization, SEO (where public-facing), and secure routing architectures. Component Design & Security: Building reusable design systems using Tailwind CSS, implementing strict form validations (e.g., Zod, Formik) for transaction inputs, and preventing XSS vulnerabilities. Key Fintech Competencies to Highlight: Observability: Centralized logging, metrics, and tracing using tools like Prometheus, Grafana, and ELK stack to trace failing financial transactions instantly. Beyond the code, modern fintech engineering requires an understanding of: API Security & Integration: Integrating with third-party banking rails, SWIFT standards, or KYC/AML verification vendors. Idempotency: Ensuring payment APIs can be retried safely without duplicating transactions. Work Experience: & Qualifications Strong analytical, problem-solving, and communication skills. Strong expertise in React.js and Next.js. Proficiency in PostgreSQL, Redis, microservices, and distributed systems. Bachelor’s Degree with 5–7 years of software engineering experience. Experience: working with Redis, messaging systems, and distributed architectures. Proficiency in Artificial Intelligence Automation and AI-assisted engineering workflows. Ability to translate complex financial business requirements: into scalable technical solutions. Strong hands-on experience: with Java Spring Boot, Spring Security, and microservice architecture. Experience: with Docker, Kubernetes, Terraform, and cloud-native infrastructure.
