Senior Software Engineer at five9

This role is ideal for a Senior Full-Stack Engineer with strong experience in the PHP/Laravel ecosystem and modern JavaScript frameworks (Vue.js preferred). You should have a solid background in building scalable, multi-tenant cloud applications and an interest in AI automation, as you'll be working on a "Studio" product that integrates LLMs and voice/SMS channels. While the base salary isn't listed, the package is competitive for the Australian market, featuring stock options (Five9 Shares) and a performance bonus scheme. The position is fully remote within Australia, offering significant flexibility, though it does involve participation in an on-call rotation to ensure service reliability for their global contact center platform. **You might be a good fit if you...** * Are proficient with PHP (Laravel), Vue.js, and Python. * Have experience with cloud infrastructure (GCP, Kubernetes) and CI/CD pipelines. * Enjoy "building from the ground up" within an R&D environment focused on practical AI solutions. * Are comfortable owning the full lifecycle of a feature, from design and coding to troubleshooting and maintenance.
