Job description

Responsibilities

• Design, build, and evolve secure developer platform capabilities using Python or TypeScript/JavaScript, GitHub Actions, Pulumi, Docker, AWS, and internal and third‑party APIs.
• Build and mature governed cloud development workspace capabilities, including secure workspace patterns using platforms such as Coder, devcontainers, approved base images, identity controls, secrets management, and controlled network access.
• Create reusable templates, documentation, reference implementations, and standardized paved‑road patterns that enable application teams to rapidly adopt secure, compliant development environments.
• Partner directly with software engineers and application teams to standardize development environments, streamline onboarding, and increase adoption of reusable platform capabilities.
• Continuously improve the developer experience by reducing environment setup time, eliminating repetitive manual work, standardizing engineering workflows, and making secure‑by‑default development practices easy to consume.
• Build operational excellence into owned platform services through monitoring, alerting, dashboards, runbooks, automation, and proactive support capabilities.
• Establish and continuously improve operational practices for developer platforms, including service ownership, platform lifecycle management, incident response, support models, and ongoing reliability improvements.
• Collaborate closely with Cybersecurity, Infrastructure, Enterprise Architecture, and application engineering teams to translate security and technical requirements into practical, automated platform controls that minimize developer friction.
• Identify recurring developer pain points and transform them into reusable frameworks, platform tooling, engineering templates, and scalable paved‑road solutions.
• Support governed AI‑assisted software development by integrating approved Generative AI tools into secure development environments, reusable templates, documentation, and standardized engineering workflows.
• Contribute across the broader Builder Tools & Platforms portfolio, supporting initiatives spanning developer tooling, secure software delivery, internal engineering frameworks, platform automation, and enterprise engineering standards.
• Work across the full lifecycle of platform engineering—from architecture and design through implementation, cloud infrastructure, CI/CD pipelines, production operations, developer enablement, and secure software delivery.
• Help transform emerging engineering needs into reliable, reusable, governed platform capabilities that enable Moderna’s Builders to innovate safely and at scale.

Minimum Qualifications

• 7+ years of experience in software engineering, platform engineering, DevOps, developer tooling, infrastructure automation, or a related role.
• Very strong software engineering experience implementing and maintaining developer platforms, internal tools, infrastructure automation, CI/CD systems, secure development environments, or secure software delivery platforms.
• Very strong programming skills in Python or TypeScript/JavaScript.
• Significant experience with GitHub, GitHub Actions, CI/CD workflows, and modern software delivery practices.
• Significant experience with AWS or another cloud provider for deploying and managing applications or developer platform services.
• Experience with Docker, devcontainers, containerized applications, or standardized development environments.
• Strong understanding of secure software development practices, software supply chain, dependency management, artifact management, secrets handling, and policy enforcement.
• Proven ability to design and implement systems that balance security, standardization, usability, reliability, and developer productivity.
• Proven experience leading technical initiatives with cross‑functional stakeholders.
• Expert troubleshooting skills across application code, build pipelines, cloud infrastructure, networking, identity, developer tooling, and third‑party platforms.
• Demonstrated ability to adapt to changing team priorities and contribute across a range of platform engineering responsibilities, including areas outside immediate prior experience.

Preferred Qualifications

• Experience with infrastructure‑as‑code tools such as Pulumi, CDK, Terraform, or similar.
• Experience building or operating internal developer platforms, remote development workspaces, devcontainer standards, scaffolding systems, CLIs, templates, or paved‑road engineering standards.
• Experience with Coder, GitHub Codespaces, Dev Containers, cloud development environments, or similar developer workspace technologies.
• Experience building reusable GitHub Actions workflows, platform automation, developer onboarding flows, or internal engineering enablement tooling.
