Lead Engineer in London

Location: London

Employment Type: Full time

Location Type: Hybrid

Department: Engineering

We’re on a mission to make real estate transactions smarter, faster, and friction-free. Real estate is the world’s largest asset class, yet the legal processes and tools behind it remain slow, manual, and underinvested. Lawyers must review dense documents line by line and piece together information across silos, all while clients demand faster, more transparent due diligence.

That’s where we come in. Orbital Copilot is the AI assistant built exclusively for commercial real estate law. Developed with former practicing real estate lawyers, it accelerates complex due diligence by up to 70% while delivering legal-grade precision. We’ve just raised a $60m Series B to accelerate our UK/US expansion. We’re trusted by leading firms like Goodwin and BCLP to remove the busywork so legal teams can focus on what they do best: applying sharp legal judgment, delivering standout client service, and getting deals over the line faster.

Working at Orbital means joining a team that’s reimagining how real estate transactions get done - moving fast, working collaboratively, and giving people the ownership to make a real impact from day one. You’ll build the tools that fix how the world’s largest asset class changes hands. We’re moving property transactions away from manual document checks toward an automated AI solution that thinks like a real estate lawyer. You won’t just execute builds - you’ll use your professional judgement to direct product development and shape the foundations of our next growth phase. The opportunity is real, and you’ll have genuine influence over what we create.

What You’ll Be Doing:

• Integrate frontier models into real production use cases to solve multimodal reasoning problems.
• Work in small teams of two to four people to direct AI agents and build agentic systems.
• Own meaningful features end-to-end - from initial architecture through to production delivery.
• Move new ideas from concept to customer-facing code within a matter of days.
• Apply visual AI to century-old legal documents, maps, and surveys that require deep reasoning.
• Continuously improve our engineering practices by using AI tools and modern techniques.

The Impact You’ll Have:

Your work will help professionals and individuals understand property transactions before they incur massive legal fees. By building for where models are going, you’ll contribute to a system that handles over 1 trillion tokens and aims to accelerate legal work by 70%. You're not just solving toy problems - you’re fixing a £multi-billion global market that’s currently stuck in archaic processes. Your technical decisions will directly determine how we scale from processing 200,000 transactions to transforming the entire industry.

What We’re Looking For:

• A deep conviction that AI will reshape industries and a desire to build at that frontier.
• Evidence of reaching a high level of excellence in a professional, academic, or personal domain.
• A generalist mindset with the willingness to work across product, design, and AI boundaries.
• Experience building modern agentic systems or reasoning through complex ML products.
• A track record of working on products generating £millions in ARR with high growth.
• Rapid career progression - such as moving from junior to senior level in under five years.
• The ability to critique AI-generated output with high standards and technical taste.

What We Offer:

Very competitive salary range plus equity options in a Series B startup. Hybrid working (1-2 days per week in our Farringdon office). 25 days holiday plus.
