Senior Software Engineer - Data Technologies Cloud Infrastructure

Location: London

Business Area: Engineering and CTO

Ref #: 10043529

As part of the Cloud Infrastructure team, you will be responsible for advancing the design and reliability of Bloomberg's cloud platform. Your work will focus on delivering secure and scalable infrastructure that empowers internal engineering teams to move quickly and safely in the public cloud. You will help evolve our IAM and access control strategies, automate infrastructure using Terraform, and reduce operational complexity through tooling and process improvements. You will also work closely with internal stakeholders to ensure the platform is aligned with real-world requirements—enhancing developer experience, improving observability, and embedding strong security and compliance practices. This is a hands-on engineering role with high impact: you will help define and deliver the infrastructure that underpins Bloomberg's data pipelines in the cloud.

You are an experienced infrastructure engineer with a deep understanding of cloud technologies and a pragmatic approach to building secure and scalable platforms. You\'re comfortable operating in a multi-tenant environment and have a strong sense of how to balance platform flexibility with the guardrails needed to protect users and systems. You take a thoughtful, engineering-first approach to automation and reproducibility, and you view security as a core aspect of every decision you make. While you\'re familiar with Kubernetes, your strength lies in running and integrating cloud-services rather than contributing directly to Kubernetes internals. You thrive in collaborative environments and are motivated by building tools and platforms that enable others to succeed.

• Hands-on experience with Terraform and Infrastructure-as-Code in a production environment.
• Strong working knowledge of AWS (e.g., IAM, VPCs, EKS, S3, CloudWatch, Security Hub).
• Understanding of multi-tenant architecture, and experience enforcing isolation at the compute, storage, and network layers.
• Practical experience implementing cloud security best practices, including least privilege, encryption, audit logging, and compliance controls.
• Familiarity with Kubernetes and the operational side of running containerized workloads.
• Programming skills in Python, Go, or similar for automation and tooling.

• Experience with hybrid infrastructure, bridging on-prem and public cloud platforms.
• Familiarity with Open Policy Agent (OPA), service mesh security, or zero-trust networking.
• Contributions to internal platforms or open-source infrastructure tooling.
• Involvement with cloud governance, cost optimization, or internal billing models.
