Thought Machine is building modern banking infrastructure to replace legacy technology in banks worldwide. The company has raised over £500m from top-tier investors including JPMorgan Chase, Standard Chartered, and Temasek, and operates across London, New York, Singapore, Sydney, and Lisbon with 550+ employees.
As a Senior Infrastructure Engineer, you will play a crucial role in designing, deploying, and maintaining the cloud-native platform that powers Thought Machine's core banking and payments technology. You'll work on a platform infrastructure team whose mission is to abstract multi-cloud complexity and reduce cognitive load for other developers, treating infrastructure as a first-class product.
Key responsibilities include:
- Scaling and optimizing the cloud-agnostic platform infrastructure (Vault) that powers the system globally
- Building intuitive control planes and automation to simplify orchestration and reduce complexity for internal engineers and bank SREs
- Designing robust, fault-tolerant architectures with comprehensive disaster recovery and business continuity planning
- Enhancing observability suites shared across the product ecosystem, providing clients with deep monitoring and insights
- Scaling and optimizing core databases and event-streaming platforms for maximum performance and cost efficiency
You'll work with cutting-edge infrastructure tooling and have the opportunity to influence how thousands of developers and bank operators interact with cloud infrastructure at scale.
REQUIREMENTS:
- Degree in Computer Science, Engineering, or similar technical field
- 5+ years of hands-on software engineering experience building and scaling infrastructure platforms (not just maintaining them)
- Strong proficiency in production-ready platform tooling using Python or Golang
- Deep understanding of container and orchestration internals (Kubernetes, Docker)
- Hands-on experience extending and integrating open-source tools (Prometheus, OpenTelemetry, Grafana)
- Proven ability to package and scale developer-facing infrastructure utilities with focus on system reliability
DESIRABLE:
- Experience building cloud-agnostic solutions across AWS, Azure, and GCP
- Technical depth in databases or event-streaming platforms (Kafka, Postgres, DuckDB)
- Track record of troubleshooting, extending, or optimizing infrastructure tools professionally
