Responsibilities
Own the full ML lifecycle: problem definition, data exploration, feature engineering, modeling, evaluation, deployment, monitoring, and iteration
Translate ambiguous business problems into clear ML objectives and success metrics
Build and maintain production-grade ML systems, including:
Batch and real-time pipelines
Feature generation and data quality checks
Model monitoring, drift detection, retraining, and reliability SLAs
Operate ML systems in mission-critical environments:
Participate in incident response and rapid mitigations
Design safe rollouts, fallbacks, and guardrails
Own models once deployed, including ongoing performance, reliability, and evolution over time
Design and run experiments (offline and online / A-B testing where applicable) and clearly communicate results and tradeoffs
Collaborate deeply with Product and Engineering to embed AI directly into customer and internal workflows
Favor reusable, extensible architectures over one-off models or demos
Help shape BillGO’s AI technical direction and standards as the company scales
Help define not just models, but how AI is used responsibly, reliably, and at scale across the company
Qualification
Required
5+ years of proven experience building and shipping ML systems into production with measurable business impact
Strong foundation in machine learning (modeling, training, evaluation, deployment), statistics, and experimentation
Fluency in Python and modern ML tooling (e.g., PyTorch, TensorFlow, scikit-learn)
Comfortable owning data pipelines and featurization (not dependent on others to make data 'model-ready')
Experience working with large, messy, real-world datasets
Ability to clearly explain models, tradeoffs, and outcomes to non-ML stakeholders
A mindset focused on leverage, simplicity, and results not process or legacy approaches
Hands-on experience with modern AI stacks (LLMs, vector databases, orchestration frameworks)
Ability to think holistically across data, infrastructure, product, and UX
Relentless curiosity with a strong builder's mindset
Bias toward action, experimentation, and measurable outcomes
Comfortable making decisions with imperfect information
Deep motivation to deliver 10X impact with 1X cost
MS or PhD in CS, ML, Statistics, Applied Math, or a related field or equivalent industry experience
Research experience that informs better decisions but does not slow shipping
Preferred
Experience in payments, fintech, B2B platforms, or workflow automation
Experience with real-time decisioning systems (latency, throughput, reliability constraints)
Applied experience with foundation models (evaluation, guardrails, fine-tuning, agentic workflows)
Experience designing decision systems, not just predictive models
A track record of replacing complex manual processes with simple, automated systems
Exposure to fraud, risk, or compliance systems
AI/ML Certifications, Published papers and contributions to the AI/ML Community
