Role Overview:

We are looking for a highly experienced Senior Full Stack Developer to lead the modernization of mission-critical enterprise applications.

In this role, you will drive the transformation of legacy Java applications into scalable, cloud-native microservices using modern Java frameworks, React, AWS, and AI-powered engineering tools.

As a senior technical leader, you will define architecture, mentor engineering teams, establish best practices, and ensure the delivery of highly available, event-driven, and observable distributed systems.

You will also leverage AI-assisted development platforms to improve engineering productivity, code quality, and delivery speed.

Key Responsibilities:

- Lead the modernization of large-scale legacy Java applications into Spring-based cloud-native microservices.

- Design scalable, resilient, and highly available distributed systems using AWS cloud services.

- Architect and develop modern frontend applications using ReactJS and TypeScript.

- Define enterprise architecture standards for APIs, microservices, event-driven systems, and cloud-native applications.

- Design and implement event-driven architectures using messaging and publish-subscribe patterns for real-time processing.

- Build high-performance, cache-driven solutions using distributed caching, read models, and materialized views.

- Ensure application scalability, resilience, fault tolerance, idempotency, retry mechanisms, and disaster recovery best practices.

- Drive performance engineering initiatives including latency optimization, memory tuning, CPU optimization, and capacity planning.

- Establish engineering excellence through robust unit testing, integration testing, automation, and CI/CD pipelines.

- Implement comprehensive observability using logging, distributed tracing, metrics, monitoring, and operational dashboards.

- Collaborate with Product Managers, Enterprise Architects, DevOps, QA, and cross-functional engineering teams to deliver enterprise-grade solutions.

- Mentor and guide development teams through architectural reviews, code reviews, and technical decision-making.

- Evaluate and integrate AI-powered software development tools such as Devin, Blitzy, GitHub Copilot, or similar platforms to enhance engineering efficiency.

- Drive secure-by-design principles, governance, coding standards, and architectural best practices across the engineering organization.

Required Skills:

- 1012 years of hands-on software engineering experience with Java-based enterprise applications.

- Strong expertise in Java, Spring Boot, Spring Framework, REST APIs, and Microservices Architecture.

- Extensive experience with ReactJS, TypeScript, JavaScript, HTML5, and modern frontend development.

- Strong experience with AWS cloud services and cloud-native application development.

- Proven experience modernizing legacy enterprise applications and migrating monolithic architectures to microservices.

- Strong understanding of distributed systems including concurrency, synchronization, scalability, consistency, fault tolerance, and high availability.

- Experience designing and implementing event-driven architectures using messaging and streaming platforms.

- Expertise in distributed caching technologies and high-performance application design.

- Strong understanding of performance tuning, profiling, monitoring, and optimization.

- Experience implementing CI/CD pipelines and automated testing strategies.

- Hands-on experience with containerization technologies such as Docker and Kubernetes is preferred.

- Experience with observability tools including logging, monitoring, metrics, and distributed tracing.

- Knowledge of API security, authentication, authorization, and enterprise integration patterns.

- Hands-on experience using AI-assisted development platforms such as Devin, Blitzy, GitHub Copilot, Cursor, or similar AI engineering tools.

- Excellent analytical, problem-solving, stakeholder management, and communication skills.

Preferred Qualifications:

- Experience leading enterprise-scale digital transformation or cloud migration initiatives.

- Exposure to financial services, accounting platforms, or other high-volume transaction processing systems.

- Experience with Infrastructure as Code (Terraform, CloudFormation) is an advantage.

- AWS Certifications or Java-related certifications are preferred.

- Experience mentoring senior engineers and leading technical architecture discussions.

What You'll Bring:

- Strong architectural thinking with the ability to design scalable, cloud-native enterprise solutions.

- Leadership in driving modernization initiatives and engineering best practices.

- Ability to influence technical decisions across multiple teams.

- Passion for innovation, AI-assisted software development, and continuous improvement.

- Ownership mindset with a focus on delivering high-quality, reliable, and maintainable software solutions.
