About This Role
The opportunity
Unity's Advertiser Growth team leverages artificial intelligence and statistical optimization to maximize returns and reduce effort for advertisers running campaigns on the Unity ad network. Our ads reach billions of devices, and every improvement we ship directly moves outcomes for thousands of advertisers worldwide.
We are looking for a senior Machine Learning Engineer to lead the design of the optimization algorithms at the heart of this mission. In this role, you will be a technical authority on how we automate campaign optimization: how bids, budgets, and targeting decisions are made to serve each advertiser's goals with minimal manual effort. You will bridge advanced quantitative methodology and large\-scale engineering, working where multi\-objective optimization, exploration–exploitation trade\-offs, long\-term value measurement, and LLM\-powered agentic systems meet real\-time production systems.
What you'll be doing
- Multi\-objective campaign optimization: Design and ship algorithms that optimize across a variety of advertiser goals — installs, ROAS, retention, and spend efficiency — under real\-world budget and marketplace constraints.
- Exploration–exploitation strategy: Design strategies (e.g., bandits, reinforcement learning) that balance short\-term performance against long\-term value, so campaigns learn efficiently without sacrificing advertiser returns.
- Long\-term impact measurement: Develop efficient methodologies to measure the long\-term impact of model and product changes, including surrogate metrics that give short\-term signals for long\-term advertiser and user value.
- Metrics frameworks for launch decisions: Define the metrics frameworks that guide what we ship — clear, trustworthy criteria that connect model improvements to advertiser outcomes and business results.
- Agentic automation for advertisers: Build LLM agent systems that automate campaign diagnostics and setup recommendations — agents that analyze campaign performance, identify root causes and recommend or apply configuration changes, so advertisers state their goals and trust the system to deliver.
- Cross\-functional technical leadership: Serve as a lead subject matter expert for ML, Product, and Engineering partners, ensuring quantitative rigor from model design through live production auctions.
What we're looking for
- 5\+ years in machine learning, data science, or applied research, ideally within ad tech, marketplaces, or other large\-scale optimization domains.
- An MS or PhD in a quantitative field (Computer Science, Statistics, Operations Research, Economics, or equivalent).
- Quantitative depth: The skills to design algorithms that optimize among competing goals, design exploration–exploitation strategies balancing short\-term and long\-term value, build efficient methodologies for measuring long\-term impact, and define metrics frameworks that guide launch decisions.
- Agentic system experience: Hands\-on experience building LLM\-based agentic systems — tool use, orchestration, retrieval over domain data, and evaluation of agent quality — ideally applied to diagnostics, recommendations, or workflow automation.
- Technical proficiency: Strong programming skills in Python or Scala, and experience with large\-scale data processing frameworks such as Spark, Snowflake, or BigQuery.
- Production track record: A history of shipping ML systems that operate on high\-volume, real\-time data and delivering measurable business impact.
- Strategic leadership: Ability to translate complex quantitative concepts into clear product roadmaps and mentor engineers on modeling and optimization rigor.
You might also have
- Prior experience with dynamic ads or creative optimization — e.g., dynamic creative assembly, creative ranking and selection, or generative creative pipelines.
- Hands\-on experience with bidding, pricing, pacing, or auction systems in digital advertising.
- Familiarity with long\-term value (LTV) prediction and surrogate metric design in mobile gaming or digital advertising.
- Experience with reinforcement learning or contextual bandits in production.
- Experience fine\-tuning or evaluating LLMs, or building multi\-agent orchestration frameworks.

About This Role
AI/ML Engineers build and deploy machine learning models in production. They work across the full ML lifecycle: data pipelines, model training, evaluation, and serving infrastructure. The role has evolved significantly over the past two years. Where ML Engineers once spent most of their time on model architecture, the job now tilts heavily toward inference optimization, cost management, and integrating LLM capabilities into existing systems. Companies want engineers who can ship production systems, and the experimenter-only role is fading fast.
Day-to-day, you're writing training pipelines, debugging data quality issues, setting up evaluation frameworks, and figuring out why your model performs differently in staging than it did on your dev set. The best ML engineers are obsessive about reproducibility and measurement. They instrument everything. They know that a model is only as good as the data feeding it and the infrastructure serving it.
Across the 3,708 AI roles we're tracking, AI/ML Engineer positions make up 70% of the market. At Unity Technologies, this role fits into their broader AI and engineering organization.
Demand for AI/ML Engineers has been strong and consistent. Unlike some AI roles that spike with hype cycles, ML engineering is a foundational need. Every company deploying AI models needs people who can keep them running, and the gap between research prototypes and production systems keeps growing.
What the Work Looks Like
A typical week might include: debugging a data pipeline that's silently dropping 3% of training examples, running A/B tests on a new model version, writing documentation for a feature flag system that lets you roll back model deployments, and reviewing a junior engineer's PR for a new evaluation metric. Meetings tend to be cross-functional since ML touches product, engineering, and data teams.
Demand for AI/ML Engineers has been strong and consistent. Unlike some AI roles that spike with hype cycles, ML engineering is a foundational need. Every company deploying AI models needs people who can keep them running, and the gap between research prototypes and production systems keeps growing.
Skills Required
Python and PyTorch dominate the requirements. Most roles expect experience with cloud platforms (AWS, GCP, or Azure) and familiarity with ML frameworks like TensorFlow or JAX. RAG (Retrieval-Augmented Generation) has become a top-3 skill requirement as companies integrate LLMs into their products. Docker and Kubernetes show up in about a third of postings, reflecting the production focus of the role.
Beyond the core stack, employers increasingly want experience with experiment tracking tools (MLflow, Weights & Biases), feature stores, and vector databases. Fine-tuning experience is valuable but less common than you'd think from reading Twitter. Most production LLM work is RAG and prompt engineering, not fine-tuning. If you have both, you're in a strong position.
Companies that are serious about AI/ML hiring tend to post specific infrastructure details in the job description: the frameworks they use, their model serving stack, their data pipeline tools. Vague postings that just say 'ML experience required' without specifics are often companies that haven't figured out what they need yet.
Compensation Benchmarks
AI/ML Engineer roles pay a median of $218,750 based on 3,817 positions with disclosed compensation. Senior-level AI roles across all categories have a median of $230,000. This role's midpoint ($198K) sits 9% below the category median. Disclosed range: $159K to $238K.

Career Path
Common paths into AI/ML Engineer roles include Data Scientist, Software Engineer, Research Engineer.
From here, career progression typically leads toward ML Architect, AI Engineering Manager, Principal ML Engineer.
The fastest path into ML engineering is through software engineering with a self-directed ML education. A CS degree helps, but production engineering skills matter more than academic credentials. Build something that works, deploy it, and measure it. That portfolio project is worth more than a Coursera certificate. For career growth, the fork comes around the senior level: go deep on technical complexity (staff/principal track) or move into managing ML teams.
What to Expect in Interviews
Expect system design questions around ML pipelines: how you'd build a training pipeline for a specific use case, handle data drift, or design A/B testing infrastructure for model deployments. Coding rounds typically involve Python, with emphasis on data manipulation (pandas, numpy) and algorithm implementation. Take-home assignments often ask you to build an end-to-end ML pipeline from raw data to deployed model.
When evaluating opportunities: Companies that are serious about AI/ML hiring tend to post specific infrastructure details in the job description: the frameworks they use, their model serving stack, their data pipeline tools. Vague postings that just say 'ML experience required' without specifics are often companies that haven't figured out what they need yet.

The AI Job Market Today
The AI job market spans 3,708 open positions across 16 role categories. The largest categories by volume: AI/ML Engineer (2,605), Data Scientist (310), AI Software Engineer (259). These three account for the majority of open positions, though smaller categories often have higher per-role compensation because of specialized skill requirements.
The seniority mix tells a story about where AI teams are in their maturity. Entry-level roles (102) are outnumbered by mid-level (1,705) and senior (1,469) positions, reflecting that most companies are past the 'build a team from scratch' phase and need experienced engineers who can ship production systems. Leadership roles (Director, VP, C-Level) total 432 positions, representing the bottleneck between technical execution and organizational strategy.
Remote work availability sits at 14% of all AI roles (508 positions), with 3,180 requiring on-site or hybrid attendance. The remote share has stabilized after the post-pandemic correction. Senior and specialized roles (Research Scientist, ML Architect) are more likely to be remote-eligible than entry-level positions, partly because experienced hires have more negotiating power and partly because these roles require less hands-on mentorship.
AI compensation is structured in clear tiers. The market median sits at $217,500. Top-quartile roles start at $272,100, and the 90th percentile reaches $325,000. These figures include base salary with disclosed compensation. Total compensation (including equity, bonuses, and sign-on) runs 20-40% higher at companies that offer those components.
Category matters for compensation. AI Safety roles lead at $300,000 median, while Prompt Engineer roles sit at $140,000. The spread between highest and lowest-paying categories reflects the premium on specialized technical skills versus broader analytical roles.
The most in-demand skills across all AI postings: Python (1,890 postings), Aws (1,103 postings), Azure (877 postings), Rag (855 postings), Gcp (631 postings), Prompt Engineering (560 postings), Pytorch (545 postings), Claude (498 postings).
