Vendelux https://vendelux.com/ is building the category-defining platform for event marketing intelligence.

Events are one of the largest and most impactful marketing channels, yet historically one of the least measurable. Vendelux brings transparency and performance to this space — helping companies discover, evaluate, and optimize their event strategy with data.

Our platform powers thousands of event decisions by delivering proprietary, AI-driven insights across hundreds of thousands of events globally. At the core of our platform is a robust ecosystem of event organizer partnerships — where organizers share first-party data, enabling richer insights for customers while receiving benchmarking and audience intelligence in return. From identifying the highest ROI conferences to enabling targeted meeting programs, Vendelux helps companies turn events into a predictable and scalable growth engine.

In addition, Vendelux Meetings extends our platform by turning insights into pipeline — using AI to identify high-value attendees and proactively book 1:1 meetings between our customers and their ideal prospects at events. This enables go-to-market teams to drive measurable ROI and maximize every event interaction.

Founded in 2021, Vendelux is a Series B SaaS company backed by top-tier investors including Tribeca Ventures, FirstMark and Hubspot Ventures. We partner with many of the fastest-growing companies in the world, and our team includes leaders from Bain, ZoomInfo, Shutterstock, FanDuel, Compass, Airbnb, Jet.com. and beyond.

Data-driven marketers have plenty of tools to optimize their digital ad spend and verify that their ads showed where they were supposed to. We build the same kinds of tools, but for data-driven event marketers, who’ve previously been limited to scanning conference badges at their booth.

We're growing, and looking for Staff Software Engineers to ship critical features and drive key infrastructure changes.

This is a full-time role based in NYC, reporting directly to our Head of Engineering. It's hybrid, 3–4 days a week in our NYC office depending on your location.
