Senior Software Engineer – Full-Stack

Location: Delhi, India; New Delhi, India

Department: Engineering

Experience: 3-6 years

About the Role

What You'll Do

• Design, develop, and maintain scalable, reliable, and maintainable backend services and APIs, primarily using PHP.
• Build and enhance services and integrations using Node.js where appropriate.
• Work with relational databases and SQL, including schema design, query optimization, indexing, and troubleshooting database performance issues.
• Design and implement effective caching strategies using Redis for performance, scalability, and distributed application requirements.
• Work with event-driven and asynchronous architectures, including queues, background jobs, event processing, and related failure-handling patterns.
• Contribute to frontend development when required, working across the stack to deliver complete product functionality.
• Investigate and resolve complex production issues, including application, database, infrastructure, performance, and integration-related problems.
• Analyze logs, traces, metrics, and application behavior to identify root causes, rather than relying only on surface-level fixes.
• Design solutions that consider performance, scalability, reliability, security, and maintainability.
• Work with AWS services and cloud infrastructure to deploy, operate, and troubleshoot applications.
• Write clean, testable, well-structured code and contribute to improving engineering standards and development practices.
• Participate in code reviews, technical discussions, design reviews, and architectural decisions.
• Automate repetitive engineering and operational tasks wherever possible.
• Work closely with Product, QA, Support, and other engineering teams to understand requirements and solve customer-impacting problems.
• Take ownership of features and technical problems end-to-end, from understanding the problem to implementation, deployment, monitoring, and resolution.
• Stay current with modern technologies, development practices, and AI-powered engineering tools, and identify opportunities to use them effectively.

Must-Have Requirements

• 3+ years of professional software engineering experience with strong hands-on production experience.
• Strong hands-on experience with PHP and backend development.
• Good practical experience with Node.js and building backend services/APIs.
• Strong understanding of SQL and relational databases, including query optimization, indexing, and database design fundamentals.
• Hands-on experience with Redis, including caching and/or other key-value use cases.
• Understanding of event-driven and asynchronous architectures, such as queues, workers, background processing, and event-based communication.
• Basic working knowledge of AWS and cloud fundamentals, including concepts such as compute, storage, networking, and managed services.
• Strong debugging, troubleshooting, and root-cause analysis skills.
• Good understanding of REST APIs, HTTP, authentication, and common backend architecture patterns.
• Ability to work effectively with an existing codebase, understand unfamiliar systems quickly, and make safe changes in production environments.
• Strong ownership and problem-solving skills, with the ability to independently drive technical problems to resolution.
• Good understanding of software engineering fundamentals, including data structures, algorithms, design principles, testing, version control, and code quality.

Nice-to-Have

• Experience with Docker and containerized application development.
• Basic understanding of Kubernetes and container orchestration.
• Experience working with cron jobs, scheduled processes, background workers, and batch jobs.
• Familiarity with monitoring, logging, alerting, tracing, and application observability tools.
• Experience with CI/CD pipelines and deployment automation.
• Experience with message brokers or event-streaming technologies such as Kafka, RabbitMQ, SQS, or similar systems.
• Experience with AWS services such as ECS/EKS, Lambda, SQS, S3, RDS, CloudWatch, or Kinesis.
• Experience with frontend technologies such as JavaScript/TypeScript, React, or similar frameworks.
• Experience with performance optimization and debugging high-volume or distributed systems.
• Experience building automation tools, scripts, or internal developer tooling.
• Familiarity with AI-assisted software development tools such as coding agents, AI-powered IDEs, code generation/review tools, or LLM-based developer workflows.
• Experience working in a SaaS, product engineering, or high-scale environment.

What Success Looks Like

• You can independently understand, develop, debug, and maintain backend systems with minimal supervision.
• Production issues are investigated systematically, with clear root-cause analysis and preventive solutions rather than temporary fixes.
• Services and APIs are reliable, performant, secure, and maintainable.
• Database and caching strategies are designed thoughtfully as system scale and traffic increase.
• You can comfortably navigate across the backend, database, infrastructure, and frontend layers when solving an engineering problem.
• You proactively identify opportunities for automation, performance improvement, reliability, and technical debt reduction.
• You contribute meaningfully to code reviews, architecture discussions, and overall engineering quality.
• You use modern tools—including AI-assisted development tools—pragmatically to improve engineering velocity without compromising code quality.
• You take ownership of problems end-to-end and consistently deliver high-quality solutions.
