Software Engineer - Core

Olo is a leading SaaS platform accelerating digital transformation in the restaurant industry, by helping customers deliver more personalised and profitable guest experiences. As a result, our digital ordering, payment, loyalty and guest engagement solutions enable brands to do more with less and make every guest feel like a regular.
While our roots are in NYC, we’re intentionally investing in Belfast and Northern Ireland as a key hub, with an established leadership presence, a local team, and community for the long term. This role is fully remote, offering you flexibility to work from anywhere within NI.
Your new role
In this role, you’ll join as a Software Engineer on the ‘Core’ team, which is part of the wider ‘Order Engineering’ group.
The Core team owns key parts of Olo’s platform, including baskets, orders, checkout, promotions, capacity management, and the services that power ordering experiences at scale. We build and maintain the APIs, services, and tools that brands and partners rely on to create reliable, flexible, and high-performing digital ordering experiences.
As a Software Engineer on this growing team, you’ll play a key role in shaping the future of these systems. You’ll help guide technical decisions, improve platform reliability and scalability, contribute hands-on code, and mentor other engineers. This is an opportunity to have meaningful influence across a broad and business-critical area of the platform while helping evolve the architecture for the next stage of growth.
On a management level, the team is led by a dedicated Engineering Manager who is based in Northern Ireland.

How you’ll make an impact
Develop an understanding of the ‘Core’ team's domain and technology stack and actively seek guidance to grow technical expertise. Handle small-to-medium features with support from more senior engineers, ensuring tasks are completed according to set timelines. Write code adhering to established coding standards and participate in code reviews to learn best practices. Collaborate with team members to understand feature requirements and implement solutions with guidance. Focus on building reliable and maintainable software components, contributing to team deliverables with a focus on quality. Utilise version control systems to manage code changes and maintain a consistent development workflow. Participate in team meetings and sprint ceremonies, such as daily stand-ups and sprint retrospectives, contributing updates and feedback. Engage in learning activities, including game days and training sessions, to build familiarity with the company's tools and processes. Troubleshoot and debug issues with guidance, learning to identify and resolve common software bugs. Demonstrate a willingness to collaborate with other engineers and stakeholders, developing teamwork skills necessary for larger projects. Demonstrate ownership of the team's delivery pipeline, ensuring that code quality, testing standards, and deployment practices are continuously optimised. Use Claude Code and GitHub Copilot extensively as part of your daily workflow, and grow your skills through hands-on AI training designed to help you become highly effective with modern AI coding agents and IDEs. Active participation in on-call duties is required, with specific responsibilities determined by your assigned team and area of expertise.
