Vendelux 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 FirstMark. We partner with many of the fastest-growing companies in the world, and our team includes leaders from Bain, ZoomInfo, Shutterstock, FanDuel, Compass, Airbnb, Forter 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 a Staff Software Engineer with a strong frontend focus to help us build the next generation of our web application and ship critical product experiences at scale.

This is a full-time position based out of NYC. We have a NYC HQ, and our preference is to have engineers work in a hybrid setup, with an expectation of 4 days in office. This role reports directly to our Head of Engineering.

As a Staff Engineer at Vendelux, you'll be a technical leader responsible for shaping how we build and evolve our customer-facing product. You'll work deeply in our frontend stack while also contributing across the broader system when needed.

What You’ll Do

• Own major product experiences end-to-end, from technical design and frontend architecture through implementation, testing, measurement, and iteration.

• Build and evolve our best-in-class web application using TypeScript, React, Shadcn/MUI, and Node.js, with a focus on usability, performance, reliability, and maintainability.

• Set technical direction for frontend architecture, patterns, and engineering practices, helping the team build a consistent and scalable application as the product grows.

• Ship high-quality, secure, well-tested software through incremental, data-driven delivery, balancing product velocity with long-term technical health.

• Solve challenging product and technical problems across the stack, working closely with product, design, data, and backend engineers to turn ambiguous requirements into great user experiences.

• Partner with our operations and revenue teams, as well as directly with customers, to understand how people use the product and turn user feedback and analytics into better product experiences.

• Identify opportunities to improve frontend performance, developer experience, observability, testing, and overall application quality.

• Work closely with our leadership team to define the product roadmap and technical strategy, particularly around the evolution of our customer-facing application.

• Be a technical leader and valued contributor within an autonomous, cross-functional agile team.

• Mentor engineers through pair programming, code reviews, architecture discussions, and hands-on technical leadership, with an emphasis on pragmatic, performant, and maintainable frontend engineering.

• Contribute across the stack when it makes sense. Our frontend engineers work closely with the APIs, data platforms, and infrastructure that power the product, so you'll have opportunities to influence the broader system as well.

Who You Are

• 10+ years of experience building complex software applications, with significant experience building modern web applications.

• Deep experience with TypeScript and React, and strong opinions about building maintainable, performant frontend systems.

• A track record of shaping and shipping valuable product features, not just building technology for its own sake.

• Strong understanding of frontend architecture, state management, API integration, testing, accessibility, performance, and modern web development practices.

• Experience working with component libraries and/or design systems such as Shadcn or MUI.

• Comfortable working across the stack and understanding how frontend decisions interact with APIs, databases, data pipelines, and infrastructure.

• Experience deploying production applications and services on AWS or GCP.

• Good judgment around technical debt, architectural tradeoffs, and when to optimize for speed versus long-term maintainability.

• Comfortable using modern AI development tools to accelerate development and improve engineering workflows.

• Experience with infrastructure as code (IaC), preferably with Pulumi.

• Familiarity with network security and protecting production applications.

• Strong written, verbal, and presentation skills, with the ability to communicate technical decisions clearly to both engineers and non-engineers.

• A strong drive to raise the engineering bar through patterns, tooling, documentation, and best practices.

• You build in the open, share context generously, and enjoy helping other engineers become more effective.

• The humor and humility to maintain perspective while working in a fast-moving environment.

• Experience working with data-intensive applications is a plus. Familiarity with moving, ingesting, and transforming data at scale is valuable, but you don't need to be a data engineer to succeed in this role.

Tech Stack

• Frontend: TypeScript, React, Shadcn / MUI, Node.js

• Backend: Python, Django, TypeScript, Node.js, MySQL, Postgres, AWS, GCP

• Data: Python, Dagster, Snowflake

• Other tools: Linear, GitHub, Datadog, Cursor / Claude Code

Benefits

• Competitive base salary and bonus

• Healthcare covering medical, dental, and vision

• Work from our NYC HQ

• Unlimited PTO, plus two company-wide shutdowns during the July 4th week and the Christmas–New Year's week
