Job description

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, 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 the UK.

Your new role

As Senior Security Engineer, you will help Olo reduce identified risks, respond to adversarial attacks while maintaining the up-time of our systems, and implement the right strategic risk mitigation measures to safeguard the data of our clients and their customers while supporting innovation. You will also provide white glove service and support to internal and external stakeholders by addressing security questions and support issues as needed, and by mentoring other engineers in how to best provide support.

Additionally, you will help in the identification and prioritisation of future project initiatives based on risk, and execute on cross-functional projects with a high degree of ownership and excellence, all while actively mentoring other team members and elevating the collective team’s capabilities and skill sets through peering and informal training.

How you’ll make an impact

• Lead improvements in detection and response capabilities, continuously optimising monitoring, alerting, and incident response processes.
• Mentor junior and mid-level engineers, setting a high standard in security practices and offering guidance for professional development.
• Participate actively in an on-call rotation, responding to escalated security incidents and coordinating effective resolutions.
• Demonstrate excellence in white-glove service delivery, ensuring security incidents are managed thoroughly and with professionalism.
• Define and collaborate on implementing leading security practices, ensuring strategies align with organisational security goals and industry standards.
• Take ownership of security project execution, prioritising tasks and aligning initiatives with team and company objectives.
• Use and optimise advanced security tools, including SIEMs and vulnerability scanners, to enhance detection, logging, and analysis capabilities.
• Conduct regular and detailed vulnerability assessments, identifying gaps in security controls and implementing mitigation strategies.
• Support compliance efforts, ensuring documentation, audits, and regulatory standards are met to maintain certifications and adherence to best practices.
• Collaborate with cross-functional teams, including development and IT, to integrate security best practices within architectural frameworks.
• Lead security awareness initiatives, educating technical teams on advanced security topics and secure coding practices.
• Stay informed on emerging security threats and technologies, continuously evaluating and integrating relevant tools or methodologies.
• Provide guidance for risk management processes, helping to establish and maintain effective risk identification and mitigation protocols.
• Develop and document security processes and procedures, ensuring consistency and readiness for both routine and high-stress security incidents.
• Support leadership with reporting by providing insights and data on incidents, vulnerabilities, project progress, and metrics to inform security decisions.
• Lead automation and process optimisation efforts by developing scripts and tools to automate repetitive security tasks as well as to enhance detection and response capabilities through the use of automation and integration of security tools.

What will set you up for success

• Bachelor's degree in Computer Science, Information Security, or a related field (or equivalent security experience).
• 5+ years of experience in security engineering and operations, including extensive experience in blue team operations, security architecture, DevOps, and general operations.
• Deep knowledge of information technology, evolving threats, attack patterns, incident response, and cybersecurity standards.
• Proven ability to develop and lead incident response, including remediation, mitigation, and regular status updates and reporting.
• Skilled in security event evaluation, discerning legitimate security incidents from false positives, incident investigation, countermeasures, and impact monitoring.
• Strong understanding of operating system, networking, and application hardening for Windows, macOS, and Linux, including virtualisation security.
• Experience deploying, maintaining, and administering security technologies like IDS, DLP, FIM, firewalls, SIEM, MFA, vulnerability assessment tools, web proxies, and WAFs.
• Experience with cloud providers and Infrastructure as Code (IaC) tools, such as Terraform, Ansible, or CloudFormation.
