JOB DESCRIPTION

At Oolio, Golang Backend Engineers are product builders who take ownership of systems that power mission-critical B2B SaaS platforms. You will design and build highly scalable, resilient, and performance-driven backend systems using Golang in a fast-growing, scale-up environment.

You will collaborate closely with Product, Design, and Engineering teams to translate business requirements into robust distributed systems designed for growth, reliability, and long-term technical excellence.

RESPONSIBILITIES

• Own end-to-end development of backend services—from architecture and design to deployment, observability, and production reliability.
• Design and implement scalable, distributed microservices using Golang with strong emphasis on performance, concurrency, and maintainability.
• Architect and evolve event-driven systems using async messaging, queues, pub/sub, and streaming patterns to support high-scale, low-latency applications.
• Build and optimize RESTful and/or gRPC APIs that power web, mobile, and third-party integrations.
• Contribute across the stack when required, collaborating with React and Node.js services to deliver cohesive product features.
• Design systems that support offline-first capabilities, ensuring reliable data synchronization and consistency across unreliable networks.
• Develop cloud-native services deployed on AWS, leveraging Kubernetes and Docker for containerized infrastructure.
• Optimize application performance, throughput, and reliability as product usage and customer scale increase.
• Implement strong testing strategies including unit, integration, contract, and performance testing.
• Drive observability best practices including structured logging, monitoring, metrics, tracing, and alerting.
• Participate in code reviews and actively contribute to improving engineering standards and best practices.
• Troubleshoot complex production issues, perform root cause analysis, and implement long-term systemic fixes.
• Collaborate with cross-functional teams to translate business requirements into scalable and secure technical solutions.
