Junior AI Engineer (Financial Intelligence)
Location: Donostia
Join Our Team at Whitehole
Whitehole is a Family Office focused on investment excellence. We actively manage (a) a diverse portfolio of equities, alternative assets, and hedging strategies, and (b) a select group of local companies where we hold significant stakes. Our mission is to uncover opportunities that deliver consistent, long-term value by investing in high-quality businesses led by exceptional teams, aligned with their stakeholders, and built on sustainable competitive advantages.
We are looking for a Junior Artificial Intelligence Engineer with a passion for financial markets. This role blends technical expertise with financial insight, offering a unique chance to contribute to our cutting-edge technology research team.
About the role
You will own the data platform behind our investment decisions, and build the AI systems that run on top of it:
Daily ingestion of market data from external providers,
ETL/ELT pipelines,
databases and storage,
automated data quality checks,
alerts and monitoring,
diagnosis and resolution of incidents: failed jobs, incomplete series, provider changes,
LLM-based systems: retrieval workflows, tool use, multi-step reasoning,
and the validation mechanisms that make their output verifiable.
Core Technical Requirements:
Advanced Python and strong software engineering fundamentals.
SQL and familiarity with databases (relational or NoSQL).
Comfort with Linux and the command line, Git, and containers.
Experience working with APIs and structured/unstructured data.
Demonstrated experience building non-trivial projects
Ability to plan development tasks with LLMs, delegate implementation to coding agents, and design robust validation mechanisms.
Cloud platforms (AWS preferred), workflow orchestration and exposure to time series or financial market data are a plus.
AI & Systems Understanding:
Hands-on experience using LLMs as part of small systems (e.g., simple retrieval workflows, tool use, or multi-step reasoning setups).
Basic understanding of how data flows through an AI pipeline (input processing, transformation, validation, output evaluation).
Interest in structured data modeling and explicit knowledge representation.
Mindset & Operating Style:
Ownership: this is a production system that real investment decisions depend on.
Rigor with data: you notice when a number looks wrong, and you go and check.
Strong problem-solving skills.
Ability to operate autonomously in technically demanding environments.
Comfort working on complex systems.
Eligibility Requirements:
University degree in Engineering, Computer Science, Telecommunications, Physics or Mathematics.
Up to two years of professional experience.
Internships and serious personal projects count.
Based in Donostia, or willing to relocate.
Fluency in English or Spanish.
What We Offer:
Competitive salary.
Flexible hours.
Primarily on-site in Donostia, with some flexibility for remote work by agreement.
We work with a small, high-performance team. You will own your part of the stack from early on, with direct exposure to the investment team and to how decisions are made.
At Whitehole, you’ll join an investment journey that transcends financial returns— prioritizing stability, growth, and social impact. We’re not just managing assets; we’re shaping the future of a family-led industrial legacy.
