Job Description:
Prodege:
A cutting-edge marketing and consumer insights platform, Prodege has charted a course of innovation in the evolving technology landscape by helping leading brands, marketers, and agencies uncover the answers to their business questions, acquire new customers, increase revenue, and drive brand loyalty & product adoption. Bolstered by a major investment by Blackstone in Q1 2026, Prodege looks forward to more growth and innovation to empower our partners to gather meaningful, rich insights and better market to their target audiences.
As an organization, we go the extra mile to “Create Rewarding Moments” every day for our partners, consumers, and team. Come join us today!
We are looking for a Principal Machine Learning Engineer to shape the future of machine learning across Prodege’s Performance Marketing business.
This is a high-impact role for someone who wants to own more than models. You will build and evolve the production ML systems that drive outcomes across ranking, rewards, ROAS / LTV prediction, offer optimization, experimentation, and decisioning. Your work will directly influence revenue, margin, user value, and marketplace efficiency in a fast-moving AdTech / MarTech environment.
This is a deeply hands-on principal role. We are looking for someone who leads by building, shipping, and operating production ML systems; not someone who stays only at the architecture or strategy layer. You will own the ML stack end to end, from problem framing and feature strategy through model development, experimentation, deployment, observability, and lifecycle optimization.
You will build production ML systems for a business serving 120M+ registered users that has delivered $2B+ in lifetime rewards, powered by a data platform with 50M events per day, 500M records of daily pipeline throughput, 100TB Iceberg lake, and 50 Kafka topics and growing across batch and real-time workflows.
If you enjoy building real-world ML systems, working close to the business, and helping a team move toward a more AI-first engineering model, this role is for you.
What You’ll Own
The architecture and delivery of offline / online ML systems, feature pipelines, inference patterns, feedback loops, and monitoring
End-to-end ML systems spanning feature generation, training, inference, experimentation, monitoring, and lifecycle management
Production ML algorithms and decisioning systems across ranking, rewards, ROAS / LTV, personalization, and offer optimization
Experimentation frameworks that connect model performance to business outcomes
Production-grade standards across MLOps, observability, retraining, governance, and reliability
Hands-on technical leadership for the ML team through direct contribution, code reviews, and mentoring
The evolution of ML toward a more AI-first way of working
What Makes This Role Exciting
You will directly shape how machine learning drives revenue, margin, and user value
You will work on analytically complex problems across ranking, rewards, ROAS, LTV, personalization, and optimization in a high-scale AdTech / MarTech environment
You will own ML from system design through production outcome, not just model development
You will build on top of a real production data platform operating at scale: 50M daily events, 500M daily pipeline records, 100TB Iceberg lake, and 50 Kafka topics and growing
You will inherit a strong experimentation culture with 30+ ML experiments per month, 10 live experiments already this year, and a feature-rich data foundation with 1,000+ features, including user and item embeddings
You will build on real business momentum — our best ranking models are already outperforming the prior models
You will have principal-level scope to influence both the systems being built and how the broader ML organization works
You will help push the organization toward a more AI-first engineering future
What You’ll Do
Lead the design, build, and evolution of production ML algorithms and systems that drive real business outcomes
Personally drive critical implementations, proving out new approaches in production before scaling them across the team
Architect and ship scalable ML systems across offline training, online inference, feature pipelines, feedback loops, and model monitoring
Build and evolve solutions across:
ranking and recommendation
rewards optimization
ROAS / LTV prediction
campaign and offer optimization
experimentation and decisioning systems
Establish robust experimentation and measurement frameworks, including offline evaluation, A/B testing, KPI design, and post-launch validation
Make key decisions on MLOps, tooling, infrastructure, serving patterns, observability, and platform architecture
Partner closely with Data Engineering, BI, Product, Engineering, and business teams to create reliable data foundations and connect ML work to business priorities
Drive an AI-first mindset by using AI to accelerate research, prototyping, feature engineering, experiment analysis, debugging, documentation, and developer productivity
Mentor ML engineers and data scientists by leading through direct contribution and raising the bar on model quality, technical judgment, and engineering rigor
The MUST Haves:
8+ years of experience in software engineering, machine learning engineering, MLOps, or related technical fields
5+ years building, deploying, and supporting production ML systems at scale
Strong experience in AdTech, MarTech, Growth, Performance Marketing, or adjacent domains
Strong hands-on background in:
ranking
recommendation
rewards / incentives
ROAS / LTV prediction
personalization / optimization systems
Proven experience designing, shipping, and operating production ML systems end to end
Strong understanding of:
offline / online ML architecture
feature engineering and feature platforms
model serving patterns
experimentation frameworks for ML systems
A/B testing and measurement design
MLOps, retraining, monitoring, and governance
Experience partnering closely with Data Engineering / BI / Analytics teams to create clean, scalable, and trustworthy data foundations for ML
Strong system design skills with sound judgment across performance, reliability, scalability, and cost
Ability to guide teams toward an AI-first way of working, while maintaining strong validation and engineering discipline
Strong technical leadership and mentoring capability, with the ability to influence across teams without direct authority
Comfort operating in ambiguity and still driving systems into production
Nice to Have
Experience with counterfactual reasoning, causal inference, or uplift modeling
Experience in rewards, offer ecosystems, customer value optimization, or monetization platforms
Experience with streaming or near-real-time decisioning systems
Experience building ML platforms or shared experimentation infrastructure
Master’s degree or PhD in AI, Machine Learning, or a quantitative field
Familiarity with modern AI-assisted / AI-first development practices across engineering and data science teams
