Job description

Location: Marylebone, London (Hybrid)

Job type: Full time

Who we are

At Tenzo, we’re transforming the way restaurants operate. Our Restaurant Reporting & Intelligence platform brings together data from multiple systems to deliver real-time, actionable insights - helping operators boost sales, cut waste, and run smoother businesses. As one of our customers put it, “It’s helped us make smarter, faster decisions and spot opportunities we might have missed before.”

We’re a team of hospitality enthusiasts and tech builders backed by top-tier Silicon Valley investors and guided by experienced advisors including Jane O'Riordan and Floor Bleeker. We work with 200+ logos including leading hospitality brands like IHG hotels, Knoops, JKS, and Time Out Markets across Asia, Africa, North America, Europe, and Australia — and we’re just getting started. Join us on our mission to help restaurants around the world move from surviving to thriving.

About the role

You’ll join the APA (Analyse, Predict & Act) team that owns everything customers actually look at: the web app, the mobile app, the metrics engine behind our analytics cards, the scheduled reports, and our AI and MCP services.

A typical feature means adding a query capability to a Django service, exposing it through an API, then building the interface for it in React. You own that whole path. Right now that means a big push on our BI capabilities, covering new chart types, heatmaps, drilldowns and a reworked dashboard grid, plus targets and budgets, a semantic layer, and AI features including a chat over a customer's own data.

What you’ll be doing

• Performance work. These are dashboards over millions of rows of transaction data, and speed is a feature.
• Targets and budgets: letting operators set goals per site, per revenue centre, and track against them.
• Our semantic layer, so metrics mean the same thing everywhere they're used.
• AI features: dashboard summaries, an AI chat over a customer's own data, and our MCP server that lets tools like Claude query Tenzo directly
• A significant push on our BI capabilities, including new chart types, heatmaps, and more flexible ways to organise and explore your data.

What we’re looking for

• Substantial experience (around 4-6 years) building, shipping, and maintaining production software.
• Real backend services in Python (Django or similar), and the ability to write and optimize SQL under production loads.
• Genuinely capable in React and TypeScript, with a sharp eye for UX polish and detail.
• Experience working on products with active users - handling releases that can't break and data that must be protected.
• Clear, effective written communication - how you articulate technical tradeoffs in pull requests matters to us!
• Nice to have: Experience with analytics or data-heavy products, multi-tenant architectures, or handling flaky, unpredictable third-party APIs.

A Quick Note on Tech Stacks: You won't have used everything in our stack. Strong depth in Python and React, paired with the drive to pick up new tools quickly, is what counts most.
