Job Description

Want to join us at a well-funded AI startup that's really going places? Build product that customers love, by AI, in production, for real revenue at 5D. Work in a low-ego, high-learning environment.

About Us: Fifth Dimension is bringing vibe working to document-heavy industries. Today 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.

The Challenge It's 9 AM on a Monday. You're reviewing usage analytics from last week's release and notice a drop-off in a key workflow,you sketch out a hypothesis and a fix before standup. By noon, you've shipped a prototype using Claude Code that rethinks how users navigate large document sets, and you're demoing it to a product manager and a customer success lead. By Wednesday, you're on a call with a major real estate firm, listening to how they actually use the platform day-to-day,and you spot an opportunity nobody had articulated yet. By Thursday, you've shaped that insight into a spec, got buy-in, and started building. By Friday, you're celebrating with the team as a customer tells you: "This is exactly what we needed."

About You You're an expert software engineer who thinks in terms of user outcomes, not just code. You don't just ship features,you understand the problem space deeply, make sharp product calls, and build solutions that customers didn't know they needed until they can't live without them. You've honed your craft through years of practice across the full stack, from performant backends and well-designed APIs to responsive, polished frontends. You have strong product intuition,you know how to talk to customers, read between the lines of a feature request, and make pragmatic trade-offs between scope, speed, and quality. You're proficient with AI coding assistance tools like Claude Code, leveraging them to accelerate development and focus on higher-level product and architectural challenges. You understand that modern engineering means effectively collaborating with AI to maximise your productivity and creative potential. Details don't escape you. You take pride in the end-to-end user experience,from the API contract to the loading state to the edge case that only one customer hits. As someone who thrives in fast-paced environments, you adapt quickly and mentor other engineers while collaborating effectively with commercial teams and customers. You're passionate about your personal growth and see each complex problem as an opportunity to expand your capabilities. You actively seek challenges that push the boundaries of what's possible and value environments where you can both contribute your expertise and continue to evolve as an engineer.

Your Impact Reporting to our CTO Chen, you'll own and shape core product areas end-to-end,from discovery and design through to architecture, implementation, deployment, and customer adoption. Working closely with our skilled engineering team and commercial stakeholders, you'll combine deep technical ability with strong product sense to build capabilities that deliver tangible value to enterprise customers and drive the business forward. Day to Day, You Will Think like a Product Manager+: Own core product areas while balancing technical excellence with business impact,you don't wait for a spec, you help write it Own end-to-end delivery of complex features from discovery and definition through to production deployment and customer adoption Talk to customers regularly,understanding their workflows, pain points, and unarticulated needs to inform what you build Collaborate with product, design, and commercial teams to shape the roadmap and translate customer insight into robust technical solutions Leverage AI coding tools like Claude Code to accelerate development workflows Lead development of the systems that underpin our platform: Scalable APIs and backend services that power document processing, data extraction, and agentic workflows Reliable streaming and event-driven architectures for real-time user experiences Frontend experiences that make powerful AI capabilities intuitive and accessible Integrations with enterprise systems and third-party platforms Implement data privacy and security by design Champion engineering best practices: testing, observability, CI/CD, and infrastructure-as-code Mentor other engineers and help establish engineering and product-thinking best practices Invest in your own growth by taking on ambitious technical challenges and expanding your expertise Apply our engineering philosophy: intellectual honesty, effective time management, clear communication, and innovation
