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 establishedwithin our GCP platform.

Alongside this, you will play an important rolein enabling the organisation'sAI transformation. Building on our existing cloud platform foundations, you will help develop the tooling, patterns, operational capabilities, and platform services requiredto 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 intopractical, reusable capabilities that addvalue across the business.

We'relooking for someone who combines deep platform engineering expertisewith 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 businessproblems.

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.

• Strong experience designing and implementing cloud-native platforms and engineering capabilities on GCP and/or AWS.

• Experience building or maturing cloud landing zones, platform governance frameworks, and self-service developer platforms.

• Deep understanding of modern cloud architectures, including containers, Kubernetes, serverless technologies, APIs, networking, security, and identity management.

• Strong hands-on expertisewith Infrastructure as Code, with masterproficiencyin Terraform.

• Experience developing and operatinglarge-scale CI/CD, automation, and platform engineering capabilities that improve developer productivity and operational excellence.

• Experience evaluating emerging technologies, developing proof-of-concepts, and translating successful concepts into production-ready platform capabilities.

• Practical experience enabling AI and data-driven workloads on cloud platforms, including familiarity with the tooling, operational considerations, and governance requirements associated with modern AI solutions.

• Strong software engineering and automation skills, with expertisein Python and experience building reusable tooling and platform services.

• Experience with modern platformand engineering toolingsuch as GitHub Actions, Apigee, Airflow, and related cloud-native technologies.

• Expertise withobservability platforms such as Data Dog, Prometheus, Grafana, ELK, Splunk or equivalent, including monitoring, logging, tracing, reliability engineering, and incident management.

• Soundtechnical judgement with the ability to balance innovation, risk, operational excellence, and business outcomes.

• Proven ability to influence technical direction, build consensus, and drive adoptionof engineering best practices across multiple teams.

• Experience coaching and mentoring engineers, fostering technical excellence, continuous learning, and collaborative problem-solving.

• Experience working effectively within global, distributed, or multinational engineering organisations.

• Excellent communication, documentation, and stakeholder engagement skills, with the ability to explain complex technical concepts to both technical and non-technical audiences.

• A pragmatic, outcome-focused approach with a passion for simplicity, automation, observability, and continuous improvement.

• Willingness to participatein out-of-hourssupport and major incident escalation when required.

Nice to have:

• Experience building platforms that support AI-powered applications, machine learning workloads, or agentic systems.

• Experience with GCP AI services, vector databases, retrieval-augmented generation (RAG), model operations, or AI governance frameworks.

• Experience operatingin multi-cloud environments and helping organisations establishconsistent platform standards across cloud providers.
