Job summary

Tenzo in London is seeking an experienced software engineer to own backend and BI features within our APA team. You’ll add queries to Django services, expose APIs, and craft frontend interfaces in React, driving new chart types, heatmaps, and AI-assisted insights.

You’ll work on performance dashboards across large datasets, targets/budgets, a semantic layer, and an AI chat over a customer’s data. A hybrid London role with strong product focus and emphasis on data integrity awaits.

Qualifications

• 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: Analytics or data-heavy products, multi-tenant architectures, or flaky third-party APIs.

Responsibilities

• Performance work: dashboards over millions of rows of transaction data; speed is a feature.
• Targets and budgets: allow operators to set goals per site and track them.
• Semantic layer: ensure metrics mean the same thing across usage.
• AI features: dashboard summaries, AI chat on customer data, MCP server for Claude queries.
• Push on BI capabilities: new chart types, heatmaps, flexible data exploration.
