providing detailed explanationsInnovation Mindset: Forming well-reasoned opinions backed by data and continuously learningPersonal Growth: Supporting your development through challenging work and opportunities to expand your expertiseHaving Fun: We're building something extraordinary across three of the world's most exciting cities. We take the work seriously, not ourselvesWhat We're Looking For We don't care about years of experience or specific degrees. We care about what you've built, how fast you learn, and how you think. Show us your work.Demonstrable experience shipping software-personal projects, open source, freelance, startup, or professional. The context matters less than the output.Fluency with AI coding tools (Claude Code, Codex) as part of your daily workflow, not as an occasional noveltyStrong programming fundamentals, particularly in Python and TypeScript-but we welcome experience in other languages and architectural paradigms too. You should be able to read, reason about, and debug code that AI helped you write.A portfolio or body of work that shows velocity and quality: things you've built, shipped, and ideally that people have usedComfort with rapid experimentation: you prototype fast, measure outcomes, and aren't precious about throwing things awayIntellectual curiosity and honesty-you dig into problems, share what you find (including failures), and ask for help when you need itClear communication: you can explain what you built, why, and what you'd do differentlyAmbition and resilience-we're tackling hard problems at the intersection of AI and real estate, and you want to grow with usNice to Have (But Not Required)Experience contributing to open-source projectsFamiliarity with cloud platforms (GCP preferred) or infrastructure toolingPast exposure to real estate, law, or finance domainsExperience building or fine-tuning with LLM APIs (Anthropic, OpenAI, etc.)A blog, Twitter/X presence, or community contributions that show how you think about AI-first developmentWhy This Role Is Different Most early career roles put you in a box: fix bugs, write tests, shadow seniors for six months before touching anything real. This isn't that. You'll own real features from day one, shipping to enterprise customers across the US, EU, and APAC. The guardrails are the staff and principal engineers around you and a culture that values measurement over ego-not a months-long onboarding gauntlet.You'll be surrounded by staff and principal-level engineers who've built systems at scale, know the commercial real estate domain deeply, and will challenge your thinking in ways that make you better. In return, you'll challenge how fast they think things can be built. That two-way exchange is exactly what we're optimising for.There's also the opportunity to travel between our London, New York, and Singapore offices-three epicentres of global real estate.

About Us Fifth Dimension is the most prominent AI company in real estate in the world, bringing vibe working to document-heavy industries . We work with real estate businesses in the US, EU and APAC, automating complex tasks, extracting valuable insights from documents, and empowering professionals to focus on high-impact work. Our AI workspace transforms how large investment managers and developers handle leases, development documents, and investment decisions.We're a London, New York and Singapore based startup with an ample runway, backed by Tier 1 European and American investors. Our founders, Johnny Morris and Dr. Kate Jarvis bring a powerful blend of expertise (and spice ️): Johnny has 17+ years applying data and analytics to Real Estate, while Kate holds a Stanford PhD and 12 years of executive experience across Silicon Valley and London startups.At Fifth Dimension, we're demanding yet encouraging, valuing experimentation and kind challenges. Our company values, Own It, Ship It, and Don't Be Boring, drive us to deliver exceptional results while fostering a culture of innovation and continuous improvement.The Challenge It's 9 AM on a Monday. You've already got a couple of AI-generated PRs from the weekend open for review - experiments you kicked off with Claude Code on Friday that ran overnight. By 10:30, the reviews are in and you're iterating. By lunch, one feature is in staging with tests. After a quick review with a staff engineer who raises an edge case you hadn't considered, you ship v2 by 3 PM. By the end of day, real customers are using it-and you're already looking at the eval results to figure out what v3 needs.On Tuesday, you sit with one of our Solutions Engineers and a Customer Success Manager to understand why a major asset manager's lease analysis is hitting a wall. By Wednesday, you're pairing with a principal engineer to redesign the approach - they bring deep knowledge of how commercial real estate documents actually work, you bring the speed to prototype three different solutions in Claude Code before lunch. You run evals against your test suite, pick the winner, and ship it. On Thursday, you're with the PM refining the intelligence platform's UI based on what the usage data told you. On Friday, you demo everything you shipped that week. It's more than most teams ship in a sprint.That's a normal week here. And next month, you might be doing it from our New York office, or from Singapore.About You You're an AI-first engineer. While others debate whether AI tools are ready, you've been shipping with them for months, maybe years. Claude Code and Codex aren't novelties to you; they're how you work. You're outcome-obsessed and customer-obsessed: you don't just build features, you solve problems for real people and measure whether it actually worked. You've already figured out that the combination of strong fundamentals, AI-augmented development, and relentless focus on customer outcomes lets you move at a pace that surprises people.You might be early in your career by the calendar, but not in output. You've built and shipped things, side projects, open-source contributions, startup experiments, freelance work, that demonstrate you can go from idea to production. You care about quality, but you know that shipping fast and measuring is how you learn what quality actually means for users.You're not intimidated by working alongside staff and principal-level engineers. You know you have things to learn from them-deep architectural thinking, domain expertise, battle scars from systems at scale. But you also know you have something to teach: how to wield AI tools to ship 10x faster without cutting corners. That exchange excites you.You experiment compulsively. You measure obsessively. You learn fast and apply what you've learned immediately. You'd rather ship something imperfect and iterate than perfect something nobody's using.Your Impact Reporting to our CTO Chen, you'll be our first early career AI engineering hire-and that means you'll help define what AI-first engineering looks like at 5D. You'll work alongside staff and principal-level engineers who'll stretch your architectural and domain thinking, while you push the team's velocity and AI tooling practices forward. You'll own real features end-to-end, shipping to enterprise customers.Day to Day, You WillShip features to production multiple times a day, using Claude Code, Codex and AI-augmented workflows as your primary development approachOwn features end-to-end: from understanding the customer problem, through implementation, to deployment and measuring impactBuild and evolve our AI intelligence platform-from agentic workflows and evaluation infrastructure to the UI/UX that puts AI capabilities in customers' handsExperiment rapidly-prototype approaches, measure results against our evaluation framework, learn from the data, and iteratePair with staff and principal engineers who, Job Description Applied AI Engineer | London One of the fastest moving AI startups in London, backed by some of the world's top VCs and founded by real entrepreneurs with multiple exits This is a rare chance to join at an early stage and build at the absolute..., Job Description Paragon Alpha are working with one of the worlds most successful multi-strategy hedge funds, who have a huge emphasis on culture and work life balance, as well as high performance.
