AI Solutions Engineer in London

hackajob is collaborating with Third Bridge Group to connect them with exceptional professionals for this role. Third Bridge is a leading global research firm established in 2007, with a team of over 1,500 employees worldwide dedicated to fueling decisions with expert insights. We accelerate and enhance decision-making for investors and business leaders by unearthing unique expert insights across multiple sectors, geographies, and topics. For nearly 20 years, we’ve helped clients access knowledge on demand from experts, in-person and through our Library covering over 65,000 companies.

Do you get more excited by a vague problem than a fully-specced one? Are you the person who's already built something with AI before anyone asked you to? Third Bridge is creating a brand-new AI function — and you’ll be one of the first! These are founding roles. You'll be embedded with business teams across our global organisation — understanding their workflows, identifying automation opportunities, building solutions that genuinely change how people work, and making sure those solutions stick!

What You'll Do

• Discover, map, and build: You'll embed yourself with business units, get under the skin of their daily workflows, identify where AI adds real value (versus where traditional code or P&T support is the better answer), and then build and deploy the solution — hands-on, sleeves rolled up.
• Make it stick: You won't throw solutions over the fence. You'll actively train internal teams so they can own, iterate, and develop agents themselves — your goal is to make them less dependent on you over time, not more.
• Monitor and maintain in production: You'll define success KPIs for every agent you deploy and proactively track performance as models (e.g. Claude) update or data structures evolve. Problems get caught by you, not by clients.
• Govern as you go: You bake compliance and risk controls into your builds from day one — not as an afterthought. You'll work alongside Compliance, Legal, and Risk to ensure every solution is approved before it goes anywhere near a client.
• Build the knowledge base: Your prompts, playbooks, and best-practice documentation will form the reusable library that the whole team learns from.

What You'll Bring

• You bring a balance of technical experience and genuine commercial curiosity. In this role, if you only talk about the technology or only talk about the business outcome, that's a flag — you do both instinctively.
• Hands-on AI agent and prompt engineering experience: Your experience of designing and deploying production LLM solutions goes beyond side projects. You can point to concrete outputs — agents that shipped, workflows that changed, problems that got solved.
• Business analysis instincts: Before you write a single line of a prompt, you ask "what's actually broken here?" Your experience mapping processes and structuring problem statements means you build the right thing, not just a technically impressive thing.
• Technical foundations that match your level: For senior hires, your toolkit includes Python, RAG, API integrations, and agent architecture. For mid-level hires, your learning trajectory and intellectual curiosity matter as much as your current depth.
• Communication that bridges the gap: You can explain hallucination, context windows, and bidirectional encoding to a VP with no technical background — clearly, confidently, and without condescension. The training element of this role is as important as the building element.
• Pragmatic quality obsession: You favour shipped-and-good over perfect-and-delayed — but you don't ship outputs you don't understand or can't control. That's the balance this role requires.

How will you be rewarded?

• Vacation: 25 days (which increases to 28 days after 2 years of service) plus UK Bank Holidays
• Learning: personal development allowance of £1000 per year
• Health and wellbeing: private medical insurance and healthcare cash plan, a variety of health and wellbeing events to focus on mental health, Ride to Work scheme (savings on bikes and accessories)
• Future and family: pension contributions of 4% (increases with tenure) and life insurance of 4x of your base salary
• Flexibility: work from anywhere for one month per year, 2 annual volunteer days, 2 personal days when life throws you a curveball and 'Summer Fridays'
• Rewards: get points through our colleague-to-colleague recognition programme to spend on hotels, gift cards, donations to charity and more
• Social: optional social gatherings, daily breakfast and snacks, social events
• ESG: CSR, Environment and Diversity & Inclusion (including Women at Third Bridge, Pride and Blkbridge)
• Frontline Innovation: your chance to share your ideas for improvement through Hackathons and other events

Why Join Us?

• Build from zero: This function doesn't exist yet. You'll help define the tools, the standards, and the culture of AI at Third Bridge — and your fingerprints will be on it permanently.
• Variety that actually challenges you: Third Bridge operates across multiple business units and global markets. No two projects are the same — you'll be solving genuinely different problems every few months, not repeating the same build in a different coat of paint.
• Work with people who are genuinely excited: You'll report into an AI Lead with real strategic vision, work closely with a P&T team that sets strong technical frameworks, and partner with business leads who are already enthusiastic adopters — not sceptics you need to convince.

Third Bridge values your trust and is committed to the responsible management, use, and protection of personal information. We know that to be truly innovative, we need to have a diverse team around us. That is why Third Bridge is committed to creating an inclusive environment and is proud to be an equal opportunity employer. If you are not 100% sure if you are right for the role, please apply anyway, and we will be happy to consider your application.
