Trusting Social is an AI Fintech company building credit profiles for underserved consumers across Vietnam, Indonesia, India, and the Philippines, combining alternative data with advanced AI to expand access to credit. Having profiled over 1 billion consumers, the company is now pushing toward 100 million credit lines delivered — grounded throughout in strict data privacy and consumer data rights.

How You’ll Make an Impact

The Data Science team builds the models and systems behind credit scoring, fraud detection, profit optimization, and conversational AI — including the speech recognition, LLM, and text-to-speech technology that powers voice interactions with customers. As an MLE on this team, you'll sit at the center of that conversational AI stack: designing the decisioning logic, tuning the agents, and building the evaluation systems that keep them reliable in production.

You thrive here if you don't wait for a spec before you start testing an idea. You read the data, form a hypothesis, and run the experiment — and when something in the agent's behavior looks off, you notice it before it becomes a support ticket. You're comfortable being wrong in a v1 and fixing it in a v2 shipped the same week.

What You’ll Do

Conversational AI & Agent Design

• Own the design and implementation of conversational and decisioning logic that solves real business problems, not just technical ones.
• Build and customize AGI agents against specific business objectives, and adjust them as those objectives shift.

Model & Prompt Optimization

• Build systems that capture operational and user feedback, and turn that signal into concrete improvements to scripts, prompts, and models.
• Run structured experiments to raise agent performance, synthesizing results into changes you can defend with data.

Quality & Evaluation Systems

• Drive the automated QA and evaluation frameworks that measure agent performance and effectiveness — these are the systems that catch regressions before customers do.
• Build monitoring that surfaces drift early, so quality problems get caught at the source, not after they've shipped.

Data-Driven Decision Making

• Interpret results using statistical techniques and turn them into reports that drive decisions, not just describe what happened.
• Communicate findings clearly to both technical and non-technical stakeholders — a good model means nothing if no one acts on it.

What We’re Looking For

Experience & Background

• Minimum 2 years of experience in IT, Computer Science, Banking, or Finance.
• Proficiency in Python, R, or Java.
• Strong hands-on experience in machine learning, statistics, and experimentation.
• Experience with SQL databases and statistical analysis.
• Familiarity with bank-related products like unsecured personal loans and credit cards is preferred.
• Experience with big data processing is a plus.
• Startup or tech background is a strong plus.

How You Work

• You actively use AI tools to craft precise prompts, critically evaluate model outputs, and extend what you can build and ship on your own.
• You experiment proactively instead of waiting to be told what to build — you produce results, then bring them to the table.
• You move fluidly between ML, data, and business context, coordinating across product and engineering without needing a handoff document.
• You treat every failed experiment as a learning input and keep sharpening your craft without being told to.

Skills & Competencies

• Product Architect — Prototypes working agentic systems, reads the metrics they produce, and iterates before anyone has to ask.
• AI Engineer/Architect — Ships end-to-end ML and agent systems, owning the path from data pipeline to production behavior.
• AI Operator — Keeps agents performing above quality threshold at target cost, catching drift before it reaches customers.
• Strong English communication skills (spoken and written — professional fluency required).
• High adaptability and comfort operating in fast-paced, ambiguous environments.
