Senior Fullstack Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Fullstack Engineer based in India. As a Senior Fullstack Engineer, you will play a key role in developing and scaling a global SaaS platform that connects communities with volunteer opportunities and supports large-scale events and social initiatives. You will work across the frontend and backend to build reliable, high-performance applications using modern technologies, including Laravel, PHP, React, Next.js, and AWS. Collaborating with product, design, QA, and engineering teams, you will deliver customer-focused features while contributing to architectural evolution and engineering excellence. You will help advance a transition toward event-driven architecture and domain-driven development, with a strong focus on scalability, maintainability, and performance. You will also champion automated testing, accessibility, localization, and security-conscious development practices. This fully remote opportunity offers an environment where technical ownership, continuous learning, AI-assisted development, and collaborative problem-solving are highly valued. Accountabilities • Full-stack development: Design, develop, test, and maintain scalable product features across the frontend and backend using Laravel, PHP, React, Next.js, and other relevant technologies. • API and integration development: Build and maintain robust APIs, third-party integrations, and reusable software components that support the platform's evolving business requirements. • Architecture and technical evolution: Contribute to the platform's architectural improvements, including the transition toward event-driven architecture and domain-driven development, while supporting a modular monolith approach where appropriate. • Cloud-native engineering: Develop and maintain applications within AWS-based environments, leveraging technologies such as Kubernetes (EKS), CI/CD pipelines, and observability tools to improve reliability and scalability. • Database design and optimization: Design, implement, and optimize relational data models using Aurora MySQL, PostgreSQL, and related technologies to support performance, data integrity, and long-term growth. • Quality engineering and testing: Establish and maintain effective test strategies, write unit tests, improve automated testing frameworks, monitor pipeline health, and proactively prevent regressions. • Performance and reliability: Identify bottlenecks, troubleshoot complex issues, and continuously improve application performance, system stability, and overall software quality. • Cross-functional collaboration: Partner with Product, Design, QA, and other engineering stakeholders to scope features, understand user needs, and deliver solutions that create measurable customer value. • Technical leadership and mentorship: Lead by example through high-quality code, peer reviews, technical guidance, documentation, and knowledge sharing to strengthen engineering standards across the team. • Engineering strategy and discovery: Participate in technical discovery, feature scoping, architectural discussions, and implementation planning, helping shape medium-term technical decisions and product direction. • Accessibility and localization: Ensure the platform delivers accessible, inclusive, and localized experiences for users across multiple countries and regions. • Security and compliance: Apply security-conscious engineering practices and support compliance requirements aligned with frameworks such as ISO 27001 and SOC 2. • AI-assisted development: Use AI-powered coding assistants and automation tools to accelerate feature delivery, improve testing, and streamline development workflows. Where appropriate, contribute to AI-enhanced product experiences using large language model APIs and prompt design. • Documentation and knowledge management: Maintain clear technical documentation covering code, architectural decisions, implementation details, and operational processes to support collaboration and long-term maintainability. • Continuous improvement: Identify opportunities to improve developer productivity, platform architecture, product quality, and engineering processes while taking ownership of technical challenges from discovery through delivery. Requirements • At least four years of experience building and delivering SaaS products end to end, ideally in multi-region or globally distributed environments. • Strong full-stack engineering expertise, with the ability to work confidently across frontend interfaces, backend services, APIs, and databases. • Proficiency in Laravel or modern PHP frameworks, alongside experience with contemporary frontend technologies such as React, Next.js, or Vue. • Practical experience with debugging tools such as XDebug, writing unit tests, conducting code reviews, and maintaining high standards of code quality. • Experience designing and developing scalable APIs, integrations, reusable components, and maintainable software architectures. • Familiarity with mobile application development, particularly React Native, is beneficial. • Hands-on experience with AWS cloud infrastructure, Kubernetes or EKS, CI/CD pipelines, and application observability. • Understanding of modular monolith architectures, with the ability to contribute to architectural improvements and maintain clear domain boundaries. • Strong experience with relational databases, particularly Aurora MySQL or PostgreSQL, including data modeling, query optimization, and performance tuning. • Knowledge of event-driven systems, asynchronous processing, and messaging technologies such as AWS SQS, Kafka, or Pub/Sub is advantageous. • Experience working in security-conscious or compliance-regulated environments, particularly those aligned with ISO 27001 and SOC 2. • Understanding of accessibility standards, localization, scalability, and the needs o
