Our clients in more than 160 countries compare Pepperstone’s trading app, web trader and client area with the best consumer and fintech products they use every day. We want to set that bar higher. You’ll be the most senior hands‑on engineer across our client‑facing products,



reporting directly to the CTO and providing senior technical leadership while remaining deeply hands‑on.

As our Senior Principal Engineer – Platform Engineering, your key responsibilities include but may not be limited to:

- Shape our platform technical direction: Define the multi-year architecture across AI, cloud, networking, identity and data. You’ll help engineers and leaders navigate complex technical trade-offs and align around a clear direction, while identifying scaling, cost and resilience risks before they become issues.
- Stay hands‑on with our toughest engineering challenges: Work directly on the most critical parts of our platform, writing production code and infrastructure as code and prototyping new approaches. You’ll take the lead on complex challenges across low‑latency connectivity, high‑throughput streaming, large data and identity migrations and platform reliability.
- Lead and shape AI‑native engineering: Help design the core of Pepperstone’s AI platform, from model access and agent orchestration to tool connections, retrieval, evaluation and runtime governance. You’ll use AI coding and agent tools in your day‑to‑day work while helping establish the patterns, workflows and guardrails that enable our engineers to do the same.
- Create a great developer experience: Design the paved roads that make it easier for our engineers to build and ship, spanning service templates, CI/CD, observability, secrets,



infrastructure as code and the developer platform. You’ll treat the platform as a product, using adoption and developer experience to help shape what we build next.
- Grow our technical capability: Mentor senior and staff engineers and help build an inclusive engineering community across locations. You’ll also contribute to hiring senior engineering talent and help set the bar for technical interviews.
- Partner with our technology leaders: Act as a trusted technical advisor to the CTO and Technology leadership team, bringing an independent, hands‑on perspective to complex technical decisions. You’ll help ensure security, resilience, data protection and regulatory requirements are considered from the outset.
