JOB DESCRIPTION:

At Oolio, Senior Backend Engineers - Golang are hands-on engineers who design, build, and operate scalable, reliable, and high-performance backend systems. You will take ownership across the backend engineering lifecycle - from technical design and development through testing, deployment, observability, and production support.

The role requires strong expertise in Golang, microservices, distributed systems, APIs, event-driven architectures, cloud-native technologies, and system performance. As AI continues to transform software engineering, you will also be encouraged to leverage AI-powered development tools, automation, and emerging AI capabilities to improve engineering productivity, accelerate delivery, enhance code quality, and solve real-world engineering problems.

The primary focus of this role is hands-on backend engineering, with opportunities to contribute to technical design, architecture decisions, and engineering best practices. You will work closely with Product, Design, Platform, and Engineering teams to build customer-facing products and backend capabilities that support Oolio's growing global platform.

RESPONSIBILITIES:

• Design, develop, test, deploy, and maintain reliable and scalable backend services using Golang.
• Contribute to the design and implementation of scalable microservices with strong emphasis on performance, concurrency, maintainability, and reliability.
• Contribute to technical design and architecture discussions, including HLD/LLD, service boundaries, data flows, and integration patterns.
• Design and implement event-driven systems using asynchronous messaging, queues, pub/sub, and streaming patterns where appropriate.
• Build and maintain RESTful and/or gRPC APIs that power web, mobile, and third-party integrations.
• Work collaboratively across the stack when required, including integration with React and Node.js services to deliver end-to-end product features.
• Develop and operate cloud-native services deployed on AWS, leveraging Kubernetes and Docker for containerized environments.
• Identify and resolve performance, scalability, and reliability bottlenecks as product usage and customer scale increase.
• Implement effective testing strategies including unit, integration, contract, and performance testing.
• Contribute to observability best practices including structured logging, monitoring, metrics, tracing, and alerting.
• Participate in code reviews and contribute to improving engineering standards, coding practices, and overall code quality.
• Troubleshoot production issues, perform root cause analysis, and implement sustainable fixes to prevent recurrence.
• Collaborate with other engineers to deliver high-quality solutions within agreed timelines.
• Mentor and support junior and mid-level engineers through code reviews, technical discussions, and knowledge sharing.
• Leverage AI-powered development tools and automation to improve development productivity, code quality, testing, documentation, and software delivery.
• Explore and adopt relevant AI capabilities and engineering tools that can solve practical software development and operational challenges.
