Senior Backend Engineer - Golang

About Oolio

At Oolio, we’re reimagining what hospitality software can do. From powering mission-critical payments to enabling seamless order flows across kiosks, QR, POS, and beyond—we’re building the operating system for modern hospitality.

We’re looking for Senior Backend Engineers - to drive the technical design, delivery, and team enablement for our squads.

This is a role for an engineer who loves shipping features to customers, cares deeply about code quality and reliability, and can guide a team technically while still being on the tools.

What you will do

• Provide technical leadership and guide engineering squads in decision making and problem solving
• Contribute directly to production code and help deliver reliable, scalable systems used daily by customers
• Own solution design, manage deployments, infrastructure, and repository health as a code owner
• Shape architectural decisions, review code, and provide mentorship support
• Define scope, break down execution plans, and ensure the team meets business and customer outcomes
• Identify and prioritise technical debt, proactively addressing performance, reliability, and developer-experience challenges
• Lead and contribute to engineering RFCs, bringing forward new tools, patterns, and best practices to uplift our engineering capability
• Champion fast, modern development workflows, including performant local environments, CI/CD pipelines, and rich developer tooling
• Define, measure, and own reliability metrics (e.g., latency, error rate, uptime) for the apps
• Design, evolve, and support event-driven and distributed system architectures, ensuring scalability and consistency across services
• Harness AI-powered tools to accelerate workflows, boost velocity, and drive innovation.
• Continuously elevate technical standards, ensuring a healthy, well-structured codebase and strong engineering culture
• Lead by example, remaining hands-on, approachable, and focused on enabling the team to do their best work

What you'll need?

• 7+ years of experience in software development and 4+ years of experience as a senior engineer
• 5+ Strong experience with Go, Docker, Kubernetes, and CI/CD pipelines for building scalable applications
• Designed and maintained Kubernetes manifests and Helm charts under GitOps principles, ensuring declarative, version-controlled infrastructure
• Proven expertise in designing and implementing event-driven systems for real-time, transactional workloads
• Strong familiarity with data structures and network protocols for distributed systems (key-value stores, queues, pub/sub, streaming)
• Skilled in building high availability, eventually consistent distributed systems – ideally with exposure to secure payments or hospitality platforms
• Strong knowledge of observability practices: monitoring, logging, tracing, anomaly detection
• Hands-on experience with tools like Prometheus, Grafana, OpenTelemetry, distributed tracing for proactive issue detection and API optimisation
• Passionate about staying at the cutting edge of development technologies, continuously learning and experimenting with new tools, frameworks, and methodologies to improve development practices and outcomes

Why Oolio?

• Work on mission-critical systems powering thousands of hospitality businesses.
• Join a team that values engineering excellence, autonomy, and continuous learning.
• Competitive salary, flexible work, and the chance to have real impact at scale
• Take part in our annual Hackathons, driving innovation and creativity.
• Access a yearly learning & development budget to invest in your growth.
