Senior Software Engineer – Full-Stack
Wingify Software Pvt. Ltd.
Description
About the Role
We are looking for a Senior Software Engineer with 3+ years of experience to join our engineering team and build, maintain, and evolve reliable, scalable software products.This is a backend-heavy full-stack role. You will primarily work on backend systems and services while also contributing to frontend components, APIs, integrations, and infrastructure when required. The ideal candidate is hands-on, strong at debugging complex production issues, and comfortable working across different layers of a technology stack.You should have strong experience with PHP and backend development, along with practical exposure to Node.js, SQL, Redis, event-driven systems, and cloud technologies. We are particularly interested in engineers who actively keep up with modern engineering practices and use AI-assisted development tools to improve productivity, code quality, and problem-solving.The role will involve working on real-world engineering problems where ownership, sound technical judgment, and the ability to understand and troubleshoot existing systems are as important as writing new code.
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.
