About the job

We are seeking a Software Engineer to build out our simulation and AI capabilities. You'll design and implement systems that model the CTV advertising ecosystem — auction dynamics, bidding strategies, campaign outcomes, and counterfactual scenarios — and develop AI-driven tools that accelerate how we build, test, and deploy ML systems.

Responsibilities

Design and build simulation environments that model CTV auction mechanics, inventory supply, and advertiser competition

Develop counterfactual and what-if frameworks for evaluating bidding strategies, budget allocation, and pacing algorithms offline

Build AI agents that explore strategy spaces, generate hypotheses, and automate experimentation within simulated environments

Use simulation to de-risk ML model deployments — validate new bidding and optimization strategies before they touch live traffic

Define the technical direction for simulation and AI infrastructure and mentor engineers on the team

Qualifications

Minimum

Systems programming experience in Zig or similar (C, C++, Rust)

Deep understanding of probabilistic modeling, stochastic processes, or agent-based simulation

Hands-on experience with modern AI tools: LLMs, code generation, agentic workflows — and good judgment about when they help vs. when they don't

Adtech experience: you understand RTB mechanics, and the dynamics of programmatic advertising

Ability to translate business questions ("what happens if we change our bid strategy?") into rigorous simulation frameworks

Clear written communication: you'll be defining new technical directions and need to bring others along

Ownership: you scope, design, and ship systems end-to-end with minimal direction

Demonstrated ability to use AI to improve speed and quality in your day-to-day workflow for relevant outputs

Strong track record of critical evaluation and verification of AI-assisted work (e.g., testing, source-checking, data validation, peer review)

High integrity and ownership: you protect sensitive data, avoid over-reliance on AI, and remain accountable for final decisions and deliverables.

Preferred

Strong production Python skills and experience building simulation or modeling systems

Causal inference — uplift modeling, synthetic controls, difference-in-differences, or incrementality testing

Experience with discrete event simulation, Monte Carlo methods, or digital twins

Reinforcement learning — using simulated environments for policy learning and evaluation

Experience building agentic AI systems or multi-agent simulations

Big data experience with Scala and Spark

MLOps experience — model deployment, monitoring, and pipeline orchestration on AWS
