Principal Platform Engineer

ISS STOXX is seeking a Principal Platform Engineer to join our global Platform Engineering function, responsible for the cloud platforms, engineering capabilities, and operational foundations that support our products and services worldwide. Working across both GCP and AWS, you will help shape the next evolution of our platform engineering capability. A key focus of the role will be extending and maturing our multi‑cloud platform strategy, including the development of AWS landing zone capabilities that align with the standards, automation, governance, and developer experience established within our GCP platform.

Alongside this, you will play an important role in enabling the organisation's AI transformation. Building on our existing cloud platform foundations, you will help develop the tooling, patterns, operational capabilities, and platform services required to support AI‑powered applications, agentic workflows, and emerging AI technologies at enterprise scale. As a Principal Engineer, you will work closely with peers across engineering, architecture, security, and product teams to solve complex technical challenges and influence technical direction through expertise, collaboration, and delivery.

You will evaluate emerging technologies, develop proof‑of‑concepts, and help translate promising ideas into practical, reusable capabilities that add value across the business. We're looking for someone who combines deep platform engineering expertise with strong technical judgement, creativity, and curiosity. You should be equally comfortable designing cloud platforms, improving engineering practices, automating complex processes, and exploring how emerging technologies can be applied to solve real business problems.

You will thrive in a collaborative environment where success is achieved through influence rather than hierarchy, where platform engineering is viewed as an enabler for product teams, and where balancing innovation with operational excellence is fundamental to long‑term success.

• Shape the architecture, evolution, and operational excellence of ISS STOXX's global cloud platforms across GCP and AWS, ensuring they remain secure, scalable, resilient, and easy for engineering teams to consume.
• Design, build, and mature AWS landing zone capabilities that align with the standards, governance, automation, security controls, and developer experience established with our GCP platform.
• Develop and enhance platform services, self‑service capabilities, CI/CD tooling, observability solutions, and automation frameworks that improve developer productivity and operational effectiveness.
• Contribute to our AI transformation by building the platform capabilities, tooling, operational patterns, and guardrails required to support AI‑powered applications, agentic workflows, and emerging AI technologies at enterprise scale.
• Act as a technical authority for complex platform engineering challenges, providing hands‑on leadership during critical incidents and guiding the resolution of high‑impact technical problems.
• Evaluate emerging technologies, develop proof‑of‑concepts, and translate successful innovations into practical, reusable platform capabilities that deliver measurable business value.
• Partner with engineering, architecture, security, and product teams to define technical direction, establish engineering standards, and ensure platform capabilities meet current and future business requirements.
• Drive continuous improvement across platform reliability, observability, automation, security, cost efficiency, and developer experience through data‑driven engineering practices.
• Mentor and support engineers across the organisation, promoting platform engineering best practices, technical excellence, and a culture of continuous learning and collaboration.
• Contribute to the long‑term evolution of the Platform and AI Engineering functions, helping balance operational excellence with innovation while enabling teams to deliver value quickly and safely.

• At least 10 years' experience in platform engineering, cloud engineering, or related disciplines, with a proven track record of designing and…
