Harold runs on AI. Not as a gimmick but as the actual product. Every appraisal, every verdict, every insight Harold surfaces is powered by an AI pipeline that we are building in real time. We need someone who lives and breathes this stuff to help us build it properly.
You will work directly with the CTO on the AI layer that makes Harold genuinely intelligent: the models, the pipelines, the prompts, the evals, the infrastructure that turns raw deal data into the smartest analysis in the room.
What you’ll be doing:
- Design, build, and improve the AI pipelines that power Harold's core intelligence
- Own prompt engineering, model selection, evaluation, and continuous improvement
- Build agentic workflows that make Harold proactively useful, not just reactive
- Integrate new models, APIs, and tools as the landscape moves, and it moves fast
- Work end to end from the model layer to the product surface where users see the output
About you:
- You are obsessed with what LLMs can actually do and you push them further than most people think possible
- You have built AI-powered products or pipelines before, not just called the OpenAI API once
- You follow the frontier closely (new models, new techniques, new papers) and you apply it fast
- You write clean code but you know that shipping beats perfection every time
- You are as comfortable in a system prompt as you are in a codebase
- You want to work somewhere your AI work actually matters and reaches real users

How to prepare for a job interview at Harold
✨Brush Up on Your Coding Skills
For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.
✨Know Your Tools and Frameworks
Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If Harold uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.
✨Showcase Your Projects
Bring along a portfolio that highlights our best work. This could be code samples, GitHub repositories, or any side projects we’ve built. Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.
✨Prepare for Behavioural Questions
While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
