Thought Machine's mission is bold - to properly and permanently rid the world's banks of legacy technology. To achieve this, we have developed the foundations of modern banking through core and payments technology which run natively in the cloud. What we are attempting is hard and means we need great people working together to build great technology.

At Thought Machine, our Senior Software Engineers specialised in Infrastructure play a crucial role in deploying and maintaining our cutting-edge software, developing tools and integrations with third-party infrastructure components used in our customers' environments. Our team's mission is to abstract away multi-cloud complexity and reduce cognitive load for other developers. We treat our platform infrastructure which spans, orchestration, observability, and data. As a first-class product, enabling our internal teams and global clients to operate securely and reliably at massive scale.

• Scale the Core Platform: Evolve, scale, and optimise the cloud-agnostic platform infrastructure powering Vault globally.

• Simplify Orchestration: Build intuitive control planes and automation to further abstract away infrastructure complexity, significantly easing the cognitive load for Thought Machine engineers and bank SREs.

• Design for Resiliency: Engineer robust, fault-tolerant architectures and Disaster Recovery / Business Continuity Planning (DR/BCP) systems.

• Advance Observability: Enhance our comprehensive observability suites that are shared across the entire Thought Machine product ecosystem, providing clients with deep, out-of-the-box monitoring and insights

• Optimise Data & Streaming: Scale and optimise core databases and event-streaming platforms to achieve maximum performance and scalability at the lowest cost
