About Leadature
Leadature is a B2B event-technology platform, operating since 2008, with Fortune 500 clients and a 17-year track record. We run onsite intelligence for live events: badge scanning, lead capture and retrieval, session and booth tracking, badge printing, RFID, AI enrichment, and post-event reporting. We serve both sides of an event – the organizer running the show and the exhibitors on the floor.
We are a small, senior, fully distributed team. Decisions are fast, and we work dynamically.
Why this role exists
Our platform works and it delivers for enterprise clients and SMBs, and has done for years. Over time, it inherited a lot of per-client customisations; product direction is currently split across several owners, which means we build reactively and our roadmap is decided by whichever event is next.
We are deciding now how much of it to modernise and how much to rebuild. Whoever takes this role will be one of a small number of people who genuinely understand how the product works – and central to what we build next.
If you like inheriting a real system with real clients on it, and turning manual work into product, this is that job. If you want greenfield only, it isn't.
What you will do
Support our clients
- Be the technical voice in client conversations, alongside customer success and sales
- Own client technical issues end to end — troubleshooting, data exports, configuration questions — with a client waiting
- Run and improve the enrichment delivery for client events
- Support live events. Events do not respect office hours, and during a show you will be reachable and responsive
- Travel to a small number of client events a year to see the product in the environment it runs in
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Build and customise
- Ship the customisations enterprise clients ask for, hands-on
- Stand up client registration and event pages quickly – we are comfortable with AI-assisted development where it gets a working thing in front of a client faster
- Look for the places where AI removes manual work altogether — our enrichment pipeline, badge data cleanup, and reporting are all still done by hand and should not be
- Improve the enrichment pipeline, which we currently run largely by hand
Make the knowledge transferable
- Document how the platform works – campaign structures, data models, integrations, exports
- Replace tribal knowledge with automation, tooling and sane technical governance
- Get us to a point where we can add engineers without a two-month ramp
Support clients directly
- Be the technical voice in client conversations, alongside our customer success and sales team
- Support live events. Events do not respect office hours, and during a show you will be reachable and responsive
- Occasionally travel to client events to see the product in the environment it runs in
Your first 90 days
This is real work waiting, not an onboarding exercise.
- Document the campaign architecture – how primary, lookup and vertical campaigns interconnect
- Produce a field dictionary for our event data exports, so anyone can pull a clean file
- Take ownership of our platform integrations and move them onto proper service accounts
- Come back with a prioritised product roadmap and tell us what you would change first
What we are looking for
Must have
- Strong.NET / C# engineering, and no fear of a legacy codebase. Our platform is an older ASP.NET application – you should be able to read it, ship into it, and say honestly what is load-bearing and what should be replaced
- Fluent in a modern stack too, because that is where we are heading: current.NET (8 or later) with ASP.NET Core, Entity Framework Core, SQL Server or PostgreSQL, React with TypeScript, and containerised deploys with CI/CD. You don't need every one of these, but you should have built and shipped on a current stack recently – not only maintained an old one
- Excellent written English, and comfort being in front of enterprise clients
- Willingness to be available during live events, including outside normal hours
- Genuine AI proficiency, not curiosity. You use coding assistants and agentic tools daily and have opinions about which ones earn their place. You have used LLMs on real data work
- Self-direction. Nobody here will manage your calendar
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Nice to have
- Event technology, ticketing, registration, or conference-tech background. This is a genuine advantage, and we will weight it heavily
- Experience with badge and registration APIs generally
- Data work: reporting, enrichment, moving messy data between systems
- Having built something with an LLM in the product itself, not just in your own workflow
Working setup
- Fully remote. We work across US and European hours
- Contract engagement to start, with scope for it to grow as the platform does
- A few events a year might involve travel, fully covered
How we hire
- Short screening call
- Technical conversation with one of our senior engineers
- Test task / a working session on a real problem from our backlog
- Final conversation with our CEO
