We are hiring a Platform Software Engineer to join a core engineering group building foundational platforms used by quant, trading, and analytics teams inside a major global banking environment.
This is not an application development role.
The team builds the underlying platforms, frameworks, tooling and runtime capabilities that other engineering and quant teams build on top of. You will be working on the technical foundation layer, not business features.
Candidates from any industry (big tech, telecoms, SaaS, gaming, infrastructure, etc.) are welcome - deep platform development experience is the key requirement, not finance knowledge.

You will contribute to the design and development of internal engineering platforms, including: Building core Python-based platforms, frameworks, and shared services
Designing developer platforms used by multiple engineering and quant teams
Developing APIs, SDKs, tooling and service frameworks that enable large-scale system development
Improving scalability, reliability, and performance of shared platform components
Working on distributed systems and service architecture foundations
Enhancing CI/CD, deployment tooling, and engineering productivity platforms
Contributing to standards, patterns, and reusable infrastructure used across the organisation
Partnering with quant and engineering teams to ensure platform capabilities support advanced workloads
Required Experience (Must-Have): Strong professional experience in Python as a primary engineering language
Background in platform engineering / core systems development
Proven experience building internal platforms, frameworks, or shared engineering infrastructure
Experience designing systems that are used by other developers
Strong understanding of:
Distributed systems
Service-oriented / microservice architectures
APIs and SDK design
System performance and scalability
Experience working on large-scale, multi-team engineering environments
