Description

We are looking for a hands-on AI Product Co-Developer to join our team building production-grade agentic AI systems for complex, data-intensive environments.

This is a hybrid role sitting at the intersection of product thinking and engineering depth , you will both define what gets built and actively build it, working across the full lifecycle from discovery and requirements through to deployment and iteration.

ROLE RESPONSIBILITIES & KEY ACCOUNTABILITIES

  • Contribute to the full AI product lifecycle: discovery, requirements definition, development, testing, and deployment
  • Design, build, and iterate on LLM-powered agentic workflows for complex, data-intensive use cases, applying sound orchestration patterns and tool-use design
  • Translate business and user needs into clear, actionable product requirements and agent configurations
  • Define and monitor product performance metrics and acceptance criteria for AI outputs in production , covering accuracy, latency, cost, and auditability
  • Manage the post-launch product lifecycle: track performance, gather user feedback, and contribute to model or feature refresh cycles
  • Contribute to system optimisation across performance, cost, and operational constraints
  • Collaborate with governance teams to ensure AI outputs meet internal quality, compliance, and interoperability standards
  • Maintain a forward-looking view on the evolving AI landscape , including model capabilities, agentic frameworks, and emerging protocol standards , and translate relevant developments into product opportunities
  • Engage with internal stakeholders and cross-functional teams to support successful delivery of AI capabilities
  • Support demos and presentations of prototypes and new capabilities to internal and external audiences
  • Build and share expertise in AI product design and agentic workflows across engineering, product, and domain teams

QUALIFICATIONS & EXPERIENCE

  • 7+ years of experience spanning software or ML engineering and product development, or a closely related combination
  • Demonstrated hands-on experience building with LLMs and/or agentic frameworks , shipped products or features preferred over academic work
  • Working knowledge of how large language models and agentic systems behave in production - including tool use, prompt design, orchestration patterns, output variability, and failure modes
  • Ability to write clear product requirements and define, review, and challenge technical specifications without requiring engineering support
  • Experience evaluating and testing AI outputs , defining acceptance criteria, identifying edge cases, and working with engineering teams to resolve model or integration issues
  • Solid Python skills and familiarity with APIs, data pipelines, and cloud infrastructure
  • Experience with real-time or near-real-time data systems, with a natural sensitivity to latency, throughput, and cost trade-offs
  • Familiarity with responsible AI principles , including data quality, model performance monitoring, and bias considerations , and their implications for product design in regulated environments
  • Comfortable working across technical and commercial stakeholders , able to translate product decisions clearly for engineering teams and client-facing audiences alike
  • Exposure to AI partner platforms or ecosystems in a product, technical, or commercial capacity is an advantage
  • BA, BS, or Master's degree in Computer Science, Engineering, Mathematics, or a related field, or equivalent practical experience

  • Retirement planning
  • Paid volunteering days
  • Wellbeing initiatives
