Job Summary

We are looking for a skilled GoLang Developer with strong experience in building scalable, high-performance backend systems. The candidate should have hands-on expertise in concurrent programming, large-scale data processing, distributed job execution, API development, performance optimization, and secure coding practices.

The ideal candidate should be able to design and develop reliable backend components that can process large volumes of data efficiently while ensuring high availability, security, and performance.

Key Responsibilities

GoLang Development

Design, develop, and maintain backend services using GoLang.
Build scalable, secure, and high-performance application components.
Write clean, maintainable, reusable, and testable code.
Develop APIs, services, utilities, and backend processing modules.
Build cross-platform components for Windows and Linux environments where required.
Participate in design discussions, code reviews, and technical decision-making.

Concurrency and Parallel Processing

Implement concurrent and parallel processing using GoLang features such as:
Goroutines
Channels
Worker pools
Context handling
WaitGroups
Mutex / RWMutex
Atomic operations
Design producer-consumer models and job processing pipelines.
Handle multithreading, multiprocessing, and distributed workload execution.
Implement concurrency controls based on CPU, memory, I/O, and network utilization.
Identify and resolve race conditions, deadlocks, memory leaks, and performance bottlenecks.

Backend Processing and System Design

Build backend components for large-scale file, data, and event processing.
Implement job queues, schedulers, retry mechanisms, checkpointing, and recovery logic.
Design fault-tolerant services with proper error handling and logging.
Implement graceful shutdown, restart-safe processing, and failure recovery.
Work on distributed processing where workloads are executed across multiple nodes or services.

API and Integration Development

Design and develop REST APIs and service-to-service integrations.
Work with authentication, authorization, token-based access, and secure communication.
Integrate with third-party systems, databases, queues, and internal services.
Handle API retries, timeouts, rate limits, pagination, and error scenarios.

Performance Optimization

Optimize applications for CPU, memory, disk I/O, and network usage.
Use profiling and benchmarking tools such as pprof.
Implement batching, throttling, streaming, pagination, caching, and backpressure handling.
Improve application performance, stability, and scalability.
Troubleshoot production performance issues and provide permanent fixes.

Database and Storage

Work with relational and non-relational databases as required.
Write efficient queries and optimize data access logic.
Understand indexing, query performance, connection pooling, and transaction handling.
Collaborate with database teams for performance tuning and troubleshooting.

Security and Reliability

Follow secure coding practices.
Ensure secure handling of credentials, secrets, tokens, certificates, and sensitive data.
Implement TLS/mTLS-based secure communication where required.
Maintain proper audit logs, application logs, and error diagnostics.
Ensure backend services meet enterprise security and compliance expectations.

Documentation and Support

Prepare technical documentation for design, configuration, deployment, and troubleshooting.
Work closely with product, QA, DevOps, implementation, and support teams.
Participate in root cause analysis for production issues.
Provide technical support for deployment, performance, and stability-related issues.

Mandatory Skills

Strong hands-on experience in GoLang.
Strong understanding of Go concurrency patterns and parallel processing.
Experience in building backend services, APIs, workers, schedulers, or processing engines.
Good knowledge of data structures, algorithms, and system design fundamentals.
Experience with multithreading, multiprocessing, worker pools, and distributed processing.
Good understanding of REST APIs, networking, authentication, and secure communication.
Experience with Linux and/or Windows environments.
Strong debugging, troubleshooting, and performance tuning skills.
Good understanding of error handling, logging, retry logic, timeout handling, and recovery mechanisms.
Ability to write clean, secure, scalable, and maintainable code.
Experience with Kafka, Redis, RabbitMQ, or other messaging/queue systems.

Good To Have Skills

Experience with databases such as SQL Server, MySQL, PostgreSQL, Oracle, or MongoDB.
Experience with Elasticsearch or similar search/indexing platforms.
Experience with Docker, Kubernetes, or containerized deployments.
Experience with large-scale file processing, data processing, or event processing systems.
Knowledge of secrets management, certificates, TLS/mTLS, and secure API communication.
Experience in cybersecurity, data protection, compliance, or enterprise security products will be an added advantage.

Qualification

B.E. / B.Tech / MCA / M.Tech in Computer Science, Information Technology, or related field.
6+ years of software development experience.
Minimum 3+ years of hands-on experience in GoLang.
Prior experience in backend systems, distributed systems, high-performance services, or data processing platforms will be preferred.
