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.

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.
