Job Title
Founding Engineer / Architect
Salary
£140k-£155k + Equity
Company Description
Toutix is a venture-backed London startup building the fan-data intelligence layer for live events. Backed by world-leading growth investors, they are replacing legacy systems like Ticketmaster with a white-label platform featuring a Fan Passport identity layer, CRM, and the AI-driven "Fan Oracle" to give organizers ownership of their fan data.
Job Description
As the founding engineer and first senior hire at Toutix, you will work directly with the CTO to architect and build a high-concurrency ticketing and intelligence platform from scratch. You’ll solve complex problems involving massive traffic spikes, multi-tenant data isolation, and real-time fan signal processing while shaping the company's technical culture.
Location
London, UK
Why this role is remarkable
- You are Engineer #1, enjoying massive architectural influence and the opportunity to build a core platform from the ground up alongside a hands-on CTO.
- Toutix is disrupting the $25B+ live events industry by giving artists and venues the data ownership that incumbents like Ticketmaster historically withhold.
- The role offers significant 1% founding equity and milestone bonuses, providing true ownership in a fast-scaling startup backed by top-tier growth investors.
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

What You Will Do
- Architect and build the core multi-tenant platform, ensuring reliability through systematic automated verification, synthetic monitoring, and self-healing agent-driven triaging.
- Design high-concurrency systems to handle massive ticket on-sale spikes, implementing idempotent checkout flows and fair queueing to prevent inventory double-selling.
- Co-design the Fan Oracle data pipeline that processes real-time signals from music, ticketing, and social media into rich, actionable fan identity profiles.
The ideal candidate
- Has 5–8 years of experience in high-concurrency environments like fintech, payments, or marketplaces, having successfully navigated large-scale outages and production failures.
- Demonstrates an AI-first mindset, using coding agents as a core part of their daily workflow to maximize leverage and delivery speed.
- Possesses the technical maturity to handle the full AWS/CI-CD estate and the architectural rigor to design for scale before problems arise.

We never post fake jobs

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
