We'd love to see * Experience with image building systems (e.g., Packer, Kairos, or similar tools) and CI/CD platforms (e.g., Jenkins or equivalents). * Hands-on experience with configuration management, orchestration, or workflow systems (e.g., Chef, Ansible, Salt, Airflow or equivalents) in production environments. * Experience defining and enforcing secure operating system baselines or container layers. * Experience with one or more programming languages used for systems or product development (e.g., Go, React, Typescript, Ruby). * Experience contributing to or maintaining open source projects. * Strong interest in testing, observability, and reliability engineering practices. ## Description The Base Layers team is responsible for designing, building, and operating a composable image build platform to derive secure, tested operating system and container images for Bloomberg's managed fleet. Our platform is the foundation for a variety of large-scale, mission-critical workflows, ensuring all machines and container workloads start from a verified, secure state. Our stack leverages best-in-class open source technologies for infrastructure automation, CI/CD, and workflow orchestration. We focus on deep systems engineering, large-scale distributed architecture, and software development, with a strong emphasis on Linux and security hardening. What You'll Work On * Image Pipeline Design and Implementation - Architecting and building a composable, highly-reliable image and container base image building pipeline for both on-prem and cloud environments. * Secure Baselines and Hardening - Defining, implementing, and enforcing secure operating system and container baselines, including CIS-aligned controls, to reduce the attack surface across the fleet. * Tooling and Automation - Developing custom automation frameworks and developer-facing APIs on top of open source projects to streamline the image creation and testing lifecycle. * Provenance and Supply-Chain Security - Implementing image lineage, asset tracking, and SBOM generation to provide traceability across the image lifecycle and strengthen supply-chain security. * Testing and Verification - Integrating automated testing into the pipeline to ensure all derived images are fully tested, verified, and ready for deployment. * Image Visibility and Consumer Interfaces - Building user-facing tools and web interfaces to allow consumers to inspect base image states, metadata, provenance, and compatibility, enabling informed adoption and derivation decisions. * Upstream OSS Contributions - Collaborating with the broader open source community to enhance the tooling we rely on. Why Join Us * Solve hard problems at scale: performance tuning, orchestration of massive workloads, and automation of global fleets. * Work in a hybrid environment that blends systems reliability engineering with software development. * See your work impact thousands of developers across Bloomberg and developers worldwide through open source. * Bring strong engineering principles and informed tool recommendations, helping evolve the platform for the benefit of the product and its users. * Be part of a team that values deep technical curiosity, collaborative problem-solving, and bold thinking. ## Related Videos - [Coffee with Developers: David Heinemeier Hansson](https://www.wearedevelopers.com/videos/875-coffee-with-developers-david-heinemeier-hansson) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Go with the Flow: Stop the Leaks Before Your Memory's a Waterfall!](https://www.wearedevelopers.com/videos/100073-go-with-the-flow-stop-the-leaks-before-your-memory-s-a-waterfall) - [Navigating the Corporate Jungle: Life as a Developer in a large Company](https://www.wearedevelopers.com/videos/621-navigating-the-corporate-jungle-life-as-a-developer-in-a-large-company) - [Coroutine explained yet again 60 years later](https://www.wearedevelopers.com/videos/690-coroutine-explained-yet-again-60-years-later) - [Scoring 2000 Products per Request: Performance Pitfalls in Golang](https://www.wearedevelopers.com/videos/2073-scoring-2000-products-per-request-performance-pitfalls-in-golang) ## Related Articles - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs)
