What you’ll do

As a Senior Software Engineer in our Security Engineering team, you will be responsible for helping keep $100b+ in payments, 100,000s of customers, and our thousands of employees safe. You'll have the opportunity to dive deep into our security program and partner with other team members to help identify projects that can drive security impact - like building internal automation tooling, owning our terabyte-scale log pipelines, and using AI to streamline how our team operates.

We're not tied to specific projects, languages, and technology - we rely on smart people diving deep to find the best solutions to hard problems. You'll also be mentoring junior team members and continuing to grow our world-class security engineering team.

Responsibilities:

  • Lead the development of security tools and applications to improve Airwallex's security, from inception to implementation.

  • Support incident response efforts by building ad-hoc tools for threat hunting, remediation and scanners.

  • Build, monitor, and maintain underlying infrastructure, including Kubernetes clusters, serverless workloads, and ETL pipelines.

  • Sit with security engineers to identify opportunities for automation and tooling development

  • Partner with product engineering teams to drive security outcomes - such as automation for patching, and development of gateways and other services to decrease risk.

  • Mentor and help grow other Software Engineers in the security team.

Who you are

  • You have a passion for solving the complex challenges within a high-growth start-up.

  • You are self-motivated, a self starter, and able to learn new skills and dive deeper into existing skills.

Minimum qualifications:

  • Bachelor’s degree in Computer Science, Information Security, or a related field.

  • 4+ years of experience as a Software Engineer, ideally with security experience.

  • Experience with production code bases

  • Experience with at least one scripting language (e.g. Python) and one systems programming language (eg. Golang, C/C++)

  • Experience with modern cloud infrastructure, including data pipelines, serverless workloads, and Kubernetes

  • Strong understanding of information security principles, practices, and technologies.

  • Proven experience working autonomously on projects - delivering them to a high quality and on time.

  • Excellent communication and interpersonal skills, with the ability to work effectively with both technical and non-technical stakeholders.

  • Ability to dive deep to find the best solution to a problem

  • Obsessive curiosity and a willingness to ask questions, gather context, and learn

Preferred qualifications:

  • Experience working in a fintech or high-growth tech company.

  • Hands on experience with AI - specifically leveraging AI to build applications

  • Experience maintaining Linux operating systems

  • Knowledge of security principles for cloud security, application security, and regulatory compliance requirements - you'll be able to learn on the job too!
