Senior Platform Engineer, Build & Developer Infrastructure

Summary:

We are looking for a Senior Platform Engineer to help build, operate, and improve the software delivery and developer infrastructure platforms used by engineering teams working on large-scale C++ and Python applications. This role combines platform engineering, CI/CD, build systems, infrastructure automation, observability, artifact management, and developer productivity. The ideal candidate has strong systems engineering fundamentals and practical experience supporting complex engineering workflows in a production-critical environment.

Responsibilities:

• Designing, building, and enhancing tools that support developer productivity, systems infrastructure, and DevOps practices
• Partner with the global Platform, Developer Infrastructure, and Release Engineering team to align regional solutions with global standards while representing local engineering, operational, and business priorities.
• Maintain and improve build and release infrastructure for large-scale C++ and Python applications, including build tooling, dependency management, CI/CD integration, artifact workflows, and developer self-service capabilities.
• Partner with software engineers, infrastructure engineers, quants, traders, and SRE teams to design, build, and operate reliable software delivery platforms.
• Design, develop, and operate scalable CI/CD pipelines for build, test, artifact promotion, deployment, and release workflows.
• Build and maintain infrastructure automation and configuration management solutions for platform, CI/CD, artifact, and developer infrastructure services.
• Develop internal developer tooling and self-service platform capabilities that reduce operational toil and improve developer productivity.
• Use containerization and orchestration technologies to support reproducible builds, reliable CI/CD execution, and consistent deployment workflows.
• Improve observability for build, CI/CD, release, and platform services through centralized logging, metrics, tracing, dashboards, and alerting.
• Troubleshoot and optimize build, CI/CD, artifact, and developer infrastructure systems with a focus on performance, reliability, scalability, and security.
• Implement software supply chain security practices, including artifact provenance, dependency management, vulnerability scanning, secret management, and CI/CD security controls.
• Participate in incident response, root cause analysis, and continuous improvement for platform-owned build, release, CI/CD, and developer infrastructure services.
• Evaluate and recommend improvements to build, release, CI/CD, developer infrastructure, observability, and software delivery platforms.

Qualifications:

• Bachelor’s degree in Computer Science, Engineering, or a related discipline, or equivalent practical experience.
• 7+ years of hands-on engineering experience building, operating, or improving software delivery, platform, infrastructure, CI/CD, DevOps, SRE, or developer productivity systems.
• Strong Linux systems knowledge and troubleshooting skills.
• Strong understanding of software build systems, especially for large C++ codebases; experience with CMake, Ninja, Bazel, Buck2, or similar tools.
• Experience with Python packaging, dependency management, and environment management tools such as pip, conda, uv, pixi, or similar.
• Experience building and operating CI/CD platforms, including pipeline design, build/test automation, artifact promotion, secrets handling, and failure diagnosis.
• Experience with artifact repositories, binary/package distribution, and artifact lifecycle management using tools such as Artifactory, Nexus, Harbor, or similar.
• Experience with infrastructure automation and configuration management tools such as Terraform, Ansible, or similar.
• Experience with containerization technologies such as Docker or Podman; familiarity with orchestration platforms such as Kubernetes, Nomad, ECS, or similar.
• Experience with cloud, hybrid, or on-premises infrastructure environments; AWS, GCP, Azure, or private infrastructure experience preferred.
• Proficiency in Python and shell scripting.
• Experience with Git and collaborative development workflows.
• Strong understanding of networking fundamentals, including DNS, load balancing, TLS, HTTP, routing, and service discovery.
• Practical understanding of distributed systems reliability concepts.
• Experience gathering developer feedback and translating recurring pain points into self-service tooling, automation, documentation, or platform improvements.
• Strong analytical and problem-solving skills with the ability to work in a fast-paced, globally distributed engineering environment.
• Excellent communication and collaboration skills.

Preferred Experience with:

• Troubleshooting C++ build, linkage, dependency, ABI, compiler, linker, and toolchain issues in large codebases.
• Modernizing legacy build systems.
• Improving build reproducibility, reducing build times, or introducing remote caching / remote execution.
• Designing reproducible Python environments and internal package distribution workflows.
• Observability platforms such as Prometheus, Grafana, OpenTelemetry, OpenSearch, or similar.
• Workflow orchestration technologies such as Airflow.
• Familiarity with GitOps deployment methodologies.
• Building internal developer portals, self-service workflows, or paved-road developer platforms.
• Systems programming languages such as C++ and/or Rust.
• Familiarity with software supply chain security practices such as dependency provenance, vulnerability scanning, and secret management.
• Integrating AI-assisted development tools into engineering workflows while maintaining appropriate security, access control, and code review practices.
