Responsibilities
We are a group of applied machine learning engineers that focus on TikTok recommendations and search engineers powering multiple product areas such as For-You-Page (FYP), Live Streaming, Global E-commerce, Local Services and more. We are developing innovative algorithms and techniques to improve user engagement and satisfaction, converting creative ideas into business-impacting solutions. We are interested in and excited about pushing the envelope of State-of-the-Art (SOTA) large scale machine learning to solve various real-world problems.
What You'll Do
- Technical Leadership: Drive the technical roadmap for our large-scale (in billions parameters) distributed real-time ML training and inferencing platforms that power the TikTok recommendation and search engines, Short Form Video (SFV) ecosystem. Have a direct business impact on Live, Global E-Commerce, Local Services and many businesses domains.
- Large-Scale Parallelism Architecture: Architect and scale multi-node distributed training systems, implementing advanced 3D parallelism strategies (Data, Tensor, Pipeline) to maximize compute efficiency and model scalability. Lead the architecture, scale-testing, and maintenance of massive distributed computing foundations, GPU cluster configurations, and orchestration pipelines, establish robust SLI/SLO frameworks while maximizing hardware utilization and cluster efficiency to expedite innovation.
- Production Inference & Serving: Build and scale low-latency, high-throughput model serving infrastructure, optimizing inference pipelines and leveraging low-level execution paths to handle massive live traffic under strict boundary isolation.
- Algorithm-Infrastructure Co-Design: Partner closely with Applied ML Research teams to co-design and pioneer next-generation Generative Recommendation systems, abstracting general-purpose components to support advanced generative paradigms in production.
- Resiliency & Fault Tolerance: Design robust, automated fault-detection systems and asynchronous checkpointing mechanisms to gracefully handle hardware drops, silent data corruption (SDC), or network-switch failures in multi-thousand GPU clusters.
- Cross-Functional Collaboration: Partner with Applied ML researchers and data platform teams to engineer high-throughput, secure multi-modal data processing and storage engines that prevent compliance friction.
- Security & Compliance Hardening: Implement and enforce strict encryption-at-rest/in-transit controls, access control lists (ACLs), and secure tenant isolation protocols across the entire compute stack to meet compliance objectives.
Qualifications

Mid Level Machine Learning Specialist Jobs: Frequently Asked Questions
How do I get a mid level machine learning specialist job?
Position your experience around ownership, not just contribution. Highlight projects where you drove decisions, improved model performance, or shipped production systems with measurable results. Tailor your resume to show depth in a core area such as NLP, computer vision, or recommendation systems. Demonstrating that you can work independently and mentor others signals mid level readiness to hiring managers far more than a list of tools.
Which companies hire mid level machine learning specialists?
Companies hiring mid level machine learning specialists right now include Scale AI, Pinterest, and Apple, based on current listings on Migrate Mate as of November 2026. Hiring at this level comes from a wide range of employers, from established technology firms and financial institutions to fast-growing startups that need engineers who can build and iterate on production ML systems with limited hand-holding.
Are there remote mid level machine learning specialist jobs?
Yes, remote and hybrid options are common at this level. About 30% of mid level machine learning specialist openings are remote or hybrid as of November 2026, reflecting strong employer appetite for experienced practitioners who can collaborate across distributed teams. On-site roles do exist, particularly at companies where data access and security requirements make remote work less practical.
How do I move up to a mid level machine learning specialist role?
The path from entry level to mid level is built on deepening specialization and expanding ownership over time. Focus on completing full project cycles rather than just supporting others, document the measurable impact of your models, and develop fluency in production infrastructure such as model deployment and monitoring. Taking initiative to mentor newer teammates and leading scoped technical decisions signals that you are ready for greater responsibility.
Which industries hire the most mid level machine learning specialists?
Mid Level machine learning specialist roles concentrate in Technology & Software, Artificial Intelligence, and Electronics & Hardware, based on current listings on Migrate Mate as of November 2026. These sectors drive hiring at this level because they have the data volume, existing ML infrastructure, and product complexity that require experienced practitioners who can operate independently and move models from experimentation into reliable production systems.
