TL;DR
Research Engineer (AI) (LLM agents and evaluation): Building the outer-loop systems that orchestrate AI coding agents, evaluate their performance, and turn production traces into reusable datasets and improvements with an accent on agent harnesses, evaluation methodology, and failure-mode analysis. Focus on designing experiments from real customer workflows, building evaluation and data pipelines, analyzing agent traces, and shipping measurable improvements to agent performance.

Location: Hybrid from the London office, with Monday, Tuesday, and Thursday as the primary in-office days

Company

hirify.global is a fast-growing Series A startup building a context layer for AI coding agents and a platform for AI-native software development.

What you will do

  • Design agent harnesses that combine tools, context, and control flow to improve coding-agent behavior.
  • Develop task- and repository-level evaluation methods, datasets, runners, and analysis workflows.
  • Build outer-loop pipelines that turn production traces and failures into reusable test cases and improvement signals.
  • Analyze agent traces at scale, identify actionable failure modes, and communicate findings to engineering.
  • Work directly with customers by joining calls, observing sessions, and using real workflows to shape research priorities.
  • Partner with engineering, product, and design to turn research experiments into shipped improvements.

Requirements

  • 4+ years of experience shipping AI/ML products in a startup or applied industry setting.
  • Recent hands-on experience with LLMs and agentic systems.
  • Deep expertise in at least one area: agent orchestration, agentic evaluation, outer-loop optimization and pipelines, or failure-mode analysis.
  • Experience building evaluation or training datasets and the supporting pipelines.
  • Strong product and customer instincts, with sound judgment about benchmarks, prototypes, and evaluation methods.
  • Master’s or PhD in a relevant computational field.

Nice to have

  • Direct experience with coding agents or code-generation systems.
  • Experience with reinforcement learning, bandits, or other outer-loop optimization frameworks applied to LLMs.
  • Experience building synthetic data, dataset infrastructure, or internal tooling used by engineers.
  • A project to share, such as a GitHub repository.

Culture & Benefits

  • Competitive salary commensurate with experience.
  • Health insurance extending to partners and dependents.
  • Pension contributions.
  • Pet-friendly office near King’s Cross with regular team lunches, drinks, and socials.
  • Warm, inclusive environment with a strong focus on diversity and welcoming underrepresented groups in tech.

Hiring process

  • Introductory call followed by a conversation with the AI Research Lead.
  • Four-hour technical take-home exercise extending a one-shot implementation.
  • Half-day onsite session with whiteboarding and hands-on activities, followed by leadership conversations.
