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 g RPC 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.
