• contribute to designing, scaling/building, evaluating, integrating, shipping, and refining reward signals for recommendations by hands-on ML development • promote and role-model best practices of ML systems development, testing, evaluation • lead collaborations and align across PZN to integrate and A/B test mid-term signals in various recommendation systems

• Own the technical build of the first-generation Trustbridge supplier app end-to-end • Lead and mentor a team of junior engineers and interns based in India • Translate business and product specifications into technical plans • Collaborate with the founder and Fractional CTO on architecture decisions

• Own the technical build of the first-generation Trustbridge supplier app end-to-end: architecture, model selection, agent design, inference layer, and production deployment. • Lead and mentor a team of 2–4 junior engineers and interns based in India. • Set the technical bar, run code reviews, and grow the team's capability. • Translate business and product specifications into buildable technical plans. • Work directly with the founder, who owns domain logic but is not a builder. • Collaborate with our Fractional CTO (background in major financial technology) on architecture decisions and technical strategy. • Once the first-generation product is in production, help shape the cross-portfolio semantic layer that connects Trustbridge, Calisade, and future ventures. • Be redeployed, over time, to new internal products and external client engagements as the practice grows.

• deliver AI/ML models from initial planning through to deployment • create AI-based prototypes to evaluate model and design options • train and tune models to optimize algorithmic outcomes • integrate models into production systems • conduct research into emerging AI models and technologies • support operational excellence and customer-centricity
