Key Responsibilities

 

1. AI Development and Prototyping

  • Rapidly design, build, and iterate machine learning models and generative AI features aligned with Vallorii’s infrastructure valuation platform.

  • Translate traditional and advanced financial models (e.g., CAPM, multifactor models, real-option theory, reinforcement learning) into user-facing prototypes and tools.

  • Collaborate with developers and UI/UX designers to integrate AI models into a scalable and user-friendly product.

​

2. Strategic Product Execution

  • Support the refinement of Vallorii’s product vision and ensure alignment with the company’s mission and user feedback.

  • Maintain a proactive understanding of trends in LLMs, NLP, and ML to ensure our toolset remains state-of-the-art and practically impactful.

  • Advise on AI architecture to ensure robustness, transparency, and compliance with regulatory standards.

 

3. Cross-Functional Collaboration

  • Work closely with Research and Advisory colleagues to translate client needs and research insights into intelligent product features.

  • Cooperate effectively with peers across units, fostering an environment of transparency and collaborative problem-solving.

 

4. Ownership and Value Creation

  • Operate with high autonomy, defining your own workstreams and priorities based on strategic objectives.

  • Focus on value generation and tangible outcomes that support Vallorii’s early-stage growth and product-market fit.

Skills & Experience

 

Required

  • A postgraduate degree (Master’s or PhD) in a relevant discipline such as Computer Science, Machine Learning, Financial Engineering, Applied Mathematics, or Econometrics.

  • 3+ years of experience in AI/ML prototyping, particularly in startups, consultancy, or product-heavy environments.

  • Strong track record in building real-world AI applications, ideally using LLMs, NLP, or decision intelligence frameworks.

  • Proficiency in Python and SQL; familiarity with API-based data integration

  • Exceptional analytical skills and the ability to balance strategic objectives with technical execution.

  • Demonstrated ability to self-direct, take full ownership of complex tasks, and drive them to completion.

​

​

Desirable

  • Deep understanding of infrastructure finance, cost of capital modeling, or regulatory economics is desirable but not essential.

  • Experience in advisory, consultancy, or early-stage product environments.

  • Familiarity with cloud services (e.g., AWS, Azure) and MLOps best practices, and HTML or Typescript for prototyping is a plus.

  • An understanding of ESG integration, regulatory impact modeling, or economic scenario planning.
