Job Description

AI Developer building secure LLM agents, evaluations, and integrations for EXANTE’s global wealth-tech trading platform. Owning backend and frontend delivery end to end.

Responsibilities:

  • Build and own the agent layer, including harness design, prompt architecture, tool layer, orchestration, and context strategy.
  • Build and own evaluations to determine whether agent changes improve performance.
  • Build backend APIs, services, data models, and integrations with company systems.
  • Build the frontend that exposes the backend capabilities.
  • Design for security risks including prompt injection, cross-tenant data leakage, and access control.
  • Extend the scope to address edge cases, failure modes, UX, and success metrics.
  • Investigate unfamiliar infrastructure, engage the right people, and drive decisions.
  • Own product scope end to end in a small, autonomous team.

Requirements:

  • Production experience building LLM agents, including harness structure, prompt architecture, tool calling, RAG, MCP, context management, and debugging pipelines.
  • Evaluation discipline focused on measuring whether changes improve agent performance.
  • Strong backend engineering skills in TypeScript/Node and working Python proficiency.
  • Ability to build competent frontend features independently.
  • Experience using Claude Code or an equivalent agent harness, including skills, subagents, hooks, and custom tooling.
  • Ability to own and maintain every line of shipped code.
  • High autonomy and ability to carry work from scope to completion.
  • Security mindset, including considering how systems could be compromised.
  • Taste for minimal, effective interface design.
  • Working proficiency in Russian and English.
  • Nice to have: financial services, brokerage, or fintech background; Slack apps; CRM integrations; OAuth/on-behalf-of flows; agent observability and tracing at scale.

Benefits:

  • Competitive salary that reflects your experience and the value you bring.
  • Flexibility that fits your life — work from home, from our office, or a mix of both. You decide what works best.
  • Flexible benefits package — choose the options that suit your life, not a one-size-fits-all bundle.
  • An informal, collaborative culture where ideas are heard and bureaucracy stays out of your way.
  • Ongoing training, education programs, and support to deepen your expertise.
  • Events that bring teams together to network and celebrate.
  • Global exposure working with colleagues from all over the world.
