Senior Software Engineer, Dev Infra

Our team owns the developer platform and release toolchain that powers TikTok’s US infrastructure. We focus on CI/CD pipelines, artifact repository management, and cloud deployment workflows, partnering closely with engineering teams and assurance partners to build, test, and release fast, secure, and compliant products.

We are looking for a battle-tested Senior Software Engineer who thrives at the intersection of infrastructure systems engineering and autonomous software to help develop our next generation SDLC, architected and scaled for the future of agent-based development.

In this role, you will design, build, and operate the critical tooling that developers and autonomous agents use every day: compilers, build chains, artifact repositories, test infrastructure and deployment workflows. You will work with engineers across teams to understand their changing development lifecycle with the use of AI, reduce friction in shipping code, and implement robust security and assurance guardrails that keep our production environments stable, auditable, and compliant.

Responsibilities

• Software Lifecycle: re-architect, design, build and maintain software development workflows (from compilation to deployment) for backend and platform services, improving reliability, speed and experience for both humans and agents, while embedding security and compliance
• Secure Supply Chain Management: Implement and manage software supply chain security controls, including SBOM generation and validation, artifact signing and attestation (e.g., SLSA), and provenance tracking to ensure the integrity of the build and release process.
• Automate Policy-as-Code Gates: Integrate and enforce automated security and compliance gates within CI/CD pipelines, such as secrets scanning, dependency risk analysis, license compliance checks, and vulnerability scanning, with fail-safe promotion rules.
• Enhance System Resilience and Disaster Recovery: Align and enhance build and release tooling to be more resilient, support Disaster Recovery (DR), and Business Continuity Planning (BCP) requirements. Implement and periodically test backup and restore procedures for critical repositories and pipelines.
• Technical Leadership & Execution: Act as the tech lead for a high-impact engineering team. Drive design reviews, establish rigorous engineering standards, manage technical debt, and ensure the team hits aggressive roadmap milestones (e.g., scaling build loads by 3X).

Minimum Qualifications

• BS/MS degree in Computer Science, Computer Engineering, or a related technical discipline with 5+ years of professional industry experience.
• Exceptional programming skills with deep proficiency in Go, Python, or Node.JS paired with a strong grasp of data structures, algorithms, and design patterns.
• Proven track record of building, deploying, and maintaining large-scale CI/CD pipelines using systems like GitLab CI, Jenkins, or similar tools.
• Experience with at least one major cloud provider (AWS, GCP, Azure, OCI), with a strong understanding of IAM concepts.
• Practical experience with artifact repositories (e.g., Docker, JFrog Artifactory, Nexus) for container images and language packages.

Preferred Qualifications

• Experience in platform or developer productivity teams, building internal tools and templates for other engineers.
• Familiarity with containerization (Docker, Kubernetes) and its security ecosystem.
• A demonstrated track record of writing clear technical documentation for security processes and runbooks.
