At OptiComm.AI, we’re rebuilding global commerce around real customer needs.Our platform predicts what each customer will buy, when, and in what quantity - and turns those predictions into decisions and actions through automation.We operate on a simple loop: Predict → Decide → Act. Predict: forecasting & next-order prediction Decide: prioritize opportunities, risks, and next best actions Act: execute via workflows and AI agents (voice/chat/WhatsApp/email + internal tools)By connecting internal business data with external signals, OptiComm.AI helps retailers, distributors, and manufacturers anticipate demand before it happens, recover lost orders, increase retention, and cut waste.We already have working live customers, a strong pipeline and an ambitious roadmap. Now we're adding a Junior AI Engineer to help grow both our predictive engine and our agentic execution platform.THE ROLE: As a Junior AI Engineer, you'll work on both sides of our platform:the predictive models that forecast orders, detect churn risk, and surface the next best action for every accountthe AI agents that turn those predictions into conversations and outcomes with real customersThis is a role for someone who takes ownership from day one. You'll get clear problems to solve and the freedom to solve them your way. We expect you to dig in, research, try things, and come back with a working solution or a well-reasoned proposal. The team is there when you need it. You're the one driving your work forward.WHAT YOU'LL OWN:Predictive modelsBuild and improve models that predict when customers will reorder, which products they'll buy, and how muchWork on churn detection, cross-sell, and next-best-action models that rank accounts by revenue potential and urgencyWork with per-customer models that are recalibrated daily, and help improve their accuracy, confidence scoring, and drift detectionExplore and engineer features from order history, buying cadence, and basket composition, plus external signals such as seasonality, weather, holidays, local events, and competitor stockoutsRun experiments, analyze errors, and draw your own conclusions about what improves performanceAI agentsBuild and improve LLM-based agents that act on predictions through voice, WhatsApp, and email: restock reminders, follow-ups, pre-filled orders, and sales conversationsConnect agents to tools and data such as our prediction models, CRM, ERP, and order systems, so they have the right context for every customerWork on the core building blocks of agents: instructions and prompts, tool calling, memory and customer context, and coordination between customer-level and sales-rep-level agentsBuild evaluation sets and test scenarios, review conversations and outcomes, find where agents fail, and improve themHelp implement guardrails that keep agents reliable, transparent, and compliant with GDPR and the EU AI ActExplore ways to improve agents beyond prompting, including fine-tuning and learning from real interaction outcomesClosing the loopHelp build the feedback loop where calls, orders, and outcomes flow back into model retraining and agent improvementContribute to pipelines, monitoring, and workflows that keep models and agents running well in productionWork with engineering, product, and client-facing teams to understand what our customers need and turn it into working featuresWHAT WE'RE LOOKING FOR:Good Python skills and hands-on experience with some of PyTorch, scikit-learn, pandas, and NumPyA solid grasp of ML fundamentals: validation, overfitting, feature engineering, evaluation metrics, and error analysisPractical knowledge of time series, forecasting, or predictive modeling on tabular data, from work, research, or personal projectsHands-on experience building with LLMs, at work or in personal projects.
