Full Job Description
About the Role

As our Senior AI Engineer, you'll help execute the AI strategy for the platform - facilitating how AI is used to help financial services create, configure, and optimize their data integrations and transformations. The AI layer is what turns a capable platform into a genuinely new category of product.

You'll work with a team of AI engineers, remain deeply hands-on technically, and work closely with the Head of Engineering to ensure the AI layer integrates cleanly with the core platform. You'll help the organization take the decisions that matter - LLM selection, agentic architecture, RAG design, evaluation frameworks, and the interaction model that defines what "AI-native" actually means when applied to financial data workflows.

The challenge here is specific: AI outputs in a financial services context need to be accurate, explainable, and auditable. Generic LLM approaches are not sufficient. You'll build something that is both intelligent and trustworthy.

Responsibilities

AI Strategy & Architecture
  • Execute the AI strategy - LLM selection and management, agentic application architecture, RAG system design, prompt engineering standards, and evaluation frameworks
  • Help design and implement the core AI capabilities: transformation generation from natural language, integration configuration assistance, data quality detection, and intelligent validation
  • Determine where AI adds genuine value vs. where deterministic logic is more appropriate - this judgment is critical for a financial services product
  • Set technical standards and foster a culture of experimentation grounded in production discipline
  • Partner with the Head of Engineering and Head of Design on cross-functional AI feature development

Hands-On Development
  • Remain deeply technical - architect and implement core AI features
  • Build and evolve the transformation generation engine, integration suggestion system, and intelligent validation layer
  • Design the AI pipeline architecture that operates reliably inside Agno-orchestrated workflows

Model Operations
  • Establish evaluation, monitoring, and continuous improvement practices for production AI systems
  • Build frameworks to measure AI output quality - accuracy, consistency, and user acceptance rates
  • Implement production monitoring and model drift detection

Responsible AI
  • Define responsible AI practices appropriate for financial services - accuracy thresholds, auditability requirements, and appropriate human-in-the-loop controls
  • Ensure AI outputs are explainable to both technical and non-technical users


Requirements

Experience
  • 3+ years AI/ML engineering; 5+ years in a product development environment
  • Player-coach track record - has led teams while remaining deeply hands-on

Technical Skills
  • Expert Python proficiency
  • Deep production LLM experience - RAG pipelines, prompt engineering, agentic systems, evaluation frameworks
  • Production experience with agentic frameworks - Agno strongly preferred; LangChain, LlamaIndex, or comparable also considered
  • Workflow orchestration experience (Temporal, Prefect, or Airflow) - AI components must operate reliably within platform workflows
  • Azure (primary) or AWS
  • Vector databases and embedding systems (Pinecone, Weaviate, pgvector, or comparable)
  • Active daily user of AI coding assistants - this is a cultural requirement, not just a preference


Nice to Have
  • Financial services, fintech, or regulated industry background - understanding of what accuracy and auditability mean in a compliance-sensitive context
  • MLOps and model deployment at scale
  • Experience fine-tuning open-source LLMs for domain-specific tasks
  • Publications, conference talks, or open-source AI contributions
  • Experience building AI features for data tools, analytics platforms, or enterprise SaaS products


Why Join Us

Category-defining work - AI-native data integration and transformation for financial services doesn't exist yet. You'll help build it from the ground up.

Enterprise backing, startup speed - The credibility, domain expertise, and runway of an established enterprise combined with the pace of a startup. This is an unusual opportunity.

Foundational team - You'll be among the first in-house hires. You'll set architecture, culture, and standards - not inherit them.

Competitive package - Market-rate salary and comprehensive benefits. Equity is available for select roles. Poland-based team members receive private healthcare (Medicover or Luxmed), Multisport card, home office setup budget, and professional development budget.
