Software Engineer - Developer Tools & Automation for Ads

TikTok USDS Joint Venture; San Jose (CA); On-site; USD 137,000 - 360,000; Full time

Job summary

TikTok USDS Joint Venture LLC seeks a highly capable engineer to build and own internal tooling powering ads system validation at scale. You will create test frameworks, data provisioning, and self-service harnesses to let engineers validate changes without hand-rolling infrastructure.

You will automate repetitive workflows, reduce toil, and improve feedback loops by integrating tooling into CI/CD and monitoring system health to surface regressions.

Qualifications

• Bachelor's degree in computer science or related technical disciplines.
• 3+ years of hands-on experience in software engineering, developer tooling, quality engineering, or test infrastructure.
• Track record of building tooling or frameworks used by other engineers.
• Hands-on authorship of CI/CD pipelines including release-gating logic.
• Demonstrated instinct for spotting repetitive or manual engineering work and replacing it with automation.

Responsibilities

• Build and own the internal tooling and platforms that power ads system validation — test frameworks, environment and data provisioning, assertion libraries, and self-service harnesses that let engineers validate changes without hand-rolling infrastructure each time.
• Identify inefficient engineering workflows and automate them away. Audit how the team actually works today — manual verification steps, repeated debugging rituals, slow feedback loops, high-toil release procedures — quantify the cost, and build the tooling that eliminates it.
• Build quality infrastructure for ads systems, including training/serving consistency checks, prediction-service invariant and fallback validation.
• Build automated system-health monitoring that surfaces regressions in business and quality metrics, routes findings to the owning engineer with enough context to act, and shortens time-to-detection.
• Integrate tooling into CI/CD as release gates, so validation runs by default rather than by remembering to run it.
• Treat internal engineers as your users — measure adoption, gather feedback, and iterate on developer experience rather than shipping tools and walking away.
• Bring in new ideas and tooling, including applying LLM and agent-based approaches to test generation, failure triage, and coverage analysis.
