Lüp is the data-driven event technology platform behind some of the world's most complex events — from SXSW Sydney to The Podcast Show London. We turn fragmented event data into a single source of truth that powers registration, smart lead capture and real-time analytics, all backed by full-service onsite delivery. Fifteen years in, award-winning (Winner at the 2026 Eventex Awards), and now scaling fast in the UK — which is where this role sits. We're not "open to AI." We're built on it. AI-assisted development is the default way we ship, not a side experiment, not a productivity hack we bolt on at the end. One of our lead engineers hasn't hand-written a line of code in over a year — and used exactly that workflow to take a brand-new product from nothing to market. We're hiring another senior engineer who already works this way, or is unmistakably on that path, and who brings the judgment to do it well. If you think of AI as autocomplete, this isn't the role. If you think of it as something you direct, push hard, and are ultimately accountable for — keep reading. The Role This is a high-autonomy, full-cycle role: you build it, you run it, you improve it, with very little hand-holding. You'll work asynchronously alongside a globally distributed team, so you need to set your own direction, unblock yourself, and ship high-quality software without waiting to be told what to do next. You're as comfortable in the weeds of the code as you are zoomed out on the architecture — and increasingly, your real value is in the second one. How We Build • AI-assisted development is the default, not a bolt-on. Most code starts with a model; your job is to direct it well, shape the architecture around it, and own the result end to end., • You're the senior engineer accountable for what ships. The workflow is fast and high-autonomy, but the quality bar doesn't move — you stand behind everything that goes out., • We give you the tools and get out of the way. Every engineer gets Claude and ChatGPT seats and is expected to use them hard. How you get the most out of them is up to you.Essential Experience & Skills, • 8–10+ years building software with .NET technologies., • Strong proficiency in C#, ASP.NET and the wider Microsoft stack., • Solid full-stack experience across back-end and modern JavaScript/React front-ends., • Strong grasp of software architecture, design patterns and engineering best practices., • Standout debugging. You diagnose and fix things others can't., • A track record of delivering autonomously, with minimal oversight, in an async or distributed setup., • Real, hands-on experience driving AI coding tools and agents to ship production code — and a clear, tested view on how you verify what they produce. This is not optional or "nice to have"; it's central to the job., • Experience guiding delivery and mentoring engineers (formal team leadership is a plus, not a must)., • Strong written communication — most of our coordination is written, so clarity on the page matters., • Comfortable in a fast-paced, collaborative scale-up environment., • Bachelor's degree in Computer Science, Engineering or a related field — or equivalent practical experienceTech You'll Work With We don't expect you to know every item on this list. Experience across most of it will set you up for success. • Back-end: C#, .NET, Node.js, • Front-end: JavaScript/TypeScript, React, Next.js, • Cloud & Architecture: AWS (provisioned with Terraform), microservices, distributed systems, scalable REST APIs. Our environment is a hybrid — the newer stack runs on AWS with Azure Service Bus for messaging, while the legacy/static side still lives on Azure, so comfort working across both clouds is a real advantage., • Databases: PostgreSQL and SQL Server — schema design, performance optimisation, data-access patterns., • DevOps & Automation: Infrastructure-as-code with Terraform, CI/CD pipelines, GitHub Actions, build and release automation., • Containers & Runtime: Docker, EKS, container orchestration and deployment., • Monitoring & Observability: Axiom, AWS CloudWatch., • AI-Enhanced Engineering: Agentic and AI-assisted development as a daily practice (Claude, GitHub Copilot and similar), plus awareness of AI/ML and LLM integration. We give every engineer Claude and ChatGPT seats and expect them to be used hard and used well.Collaboration & Communication, • Work closely with Product Managers, Engineering Managers and cross-functional teams., • Communicate clearly with both technical and non-technical stakeholders., • Monitor and report on key software performance and delivery metrics., • Maintain high-quality technical documentation and healthy development processes., • Flag issues early when they might affect delivery timelines.Why This Role Stands Out, • AI-first, and we mean it. Lüp backs AI-assisted development 100%. This is a place to push how far the workflow can go, with people who are doing the same., • Real ownership. You build it, you run it, you improve it., • High impact. Your work feeds directly into business outcomes., • Variety & scale. A complex domain on a fast-growing platform means a constant supply of genuinely interesting problems., • Established, not bureaucratic. A proven, award-winning platform building out its UK presence.
