Software Engineer Intern (TikTok-Generalized Arch-Code Intelligence & Quality Validation) - 2027 Summer

TikTok is the leading destination for short-form mobile video. They are seeking an intern to join their Agentic Ops US team, focusing on the areas of Code Graph and Quality Validation, where the intern will gain practical experience and contribute to improving code reliability and R&D efficiency.

What you'll do:

• Participate in building and optimizing the code graph, including static relationship extraction, dynamic trace data cleansing, and aggregation
• Develop static validation rules (logical and soft constraints) based on the graph, and contribute to the design and implementation of dynamic validation tools (issue reproduction, root cause localization)
• Conduct in-depth analysis of production quality issues, distill general validation patterns, and drive automation coverage
• Research and introduce cutting-edge academic and industrial techniques in code analysis, program slicing, anomaly detection, etc., to continuously improve validation effectiveness

What they're looking for:

• Currently pursuing an Undergraduate/Master degree in Software Development, Computer Science, Computer Engineering, or a related technical discipline
• Able to commit to working for 12 weeks during the Summer of 2027
• Solid programming skills with proficiency in at least one mainstream language (Go / Python / Java / C++) and good coding practices
• Deep understanding of data structures and algorithms, capable of independently reading and implementing moderately complex algorithm modules
• Research-oriented mindset: curious about unknown problems, adept at reading papers and technical blogs, and able to design solutions from first principles rather than just making code work
• Strong learning agility: able to quickly pick up new tools and frameworks, proactively track technology evolution, and apply them to practical work
• Experience with static analysis (e.g., AST, CFG, pointer analysis), dynamic tracing (e.g., eBPF, OpenTelemetry), compiler development, or automated testing
• Publications in academic conferences or journals related to code analysis, software engineering, or system reliability
• Contributions to major open-source projects, or personal tech blog/portfolio that demonstrates independent thinking and deep-dive investigation

Benefits:

• Interns have day one access to health insurance, life insurance, wellbeing benefits and more.
• Interns also receive 10 paid holidays per year
• Paid sick time (56 hours if hired in first half of year, 40 if hired in second half of year).
• Interns who are not working 100% remote may also be eligible for housing allowance.
