  • Scale a high-performance engineering organization focused on disciplined, rapid shipping.
  • Develop a senior technical-leadership layer owning architectural domains.
  • Structure governance frameworks for outsourced engineering including quality gates and security baselines.
  • Establish clear ownership models with accountable teams per system.
  • Build engineering culture emphasizing production reliability, evaluation rigor, and system observability.
  • Hire selectively for high-leverage additions rather than broad headcount growth.
  • Communicate technical roadmap clearly to leadership and board with transparent trade-off framing.

Required qualifications

Hard requirements

  • 10+ years engineering experience with at least 5 years in senior technical leadership at scale-ups or high-growth companies.
  • Demonstrated production experience building and operating multi-agent AI systems (not prototype or research contexts).
  • Deep backend and distributed-systems expertise: event streaming, microservices, API design, database scaling, observability stacks.
  • Experience operating AI systems in regulated or high-stakes commercial environments with financial or operational consequences.
  • Track record scaling engineering teams from 10 to 30+ people, including developing internal technical leadership.
  • Fintech-infrastructure familiarity (credit systems, payment flows, embedded finance) as a meaningful advantage.
  • Experience designing and governing hybrid engineering models with external delivery partners.

Technical depth

  • Strong intuitions about LLM selection, fine-tuning, and evaluation methodology.
  • Hands-on familiarity with agentic frameworks and production failure modes.
  • Architectural fluency in streaming data, real-time inference, and production ML feature engineering.
  • Understanding of AI-system reliability including rate limits, fallback strategies, latency budgets, cost modeling, and evaluation pipelines.

Key technologies

  • Agentic frameworks (LangGraph, custom orchestration).
  • Event streaming systems.
  • Microservices architecture.
  • Real-time inference systems.
  • Foundation models and LLM infrastructure.
