Founding Systems Architect / Engineer in Slough

United Kingdom (Hybrid) · Full-time

Competitive Salary + Equity

Opportunity

We\’re building TYTEN, bringing AI to the $1.5 trillion facilities management industry. The one that keeps the world running: elevators that don\’t trap people, heating that works in winter, pipes that don\’t burst on Christmas Eve.

Companies are banging down our door, demanding we build faster. We\’ve got live UK clients and we\’re scaling from pilots to thousands of sites.

We need a Founding Systems Architect / Engineer who can design and build the core infrastructure powering our AI platform. Someone who bridges architecture, system design, and hands-on building. Not here for \\\”another job,\\\” but for real impact.

What we\’re building

Our AI platform helps FM companies and technicians work dramatically better:

• Help desk automation: Orchestrates repair requests, task allocation, subcontractor coordination, reporting. Cutting processing time by 20x.
• AI-guided diagnostics: Step-by-step guidance through our app with tools, diagnostic steps, repair instructions. 25% faster repairs, 15% better first-time fix rates.

We integrate as an intelligence layer on existing ticketing systems (CMMS/CAFM). Using AI (OpenAI, Gemini, LangChain, vector stores, OCR) to solve real operational problems.

About us

Three co-founders, fully locked in:

• Vlad (CEO): Strategy, fundraising, product
• Serge (CTO): Infrastructure, AI models, technical direction
• Tom (CCO): Commercial execution

We spent 500+ hours shadowing technicians and helpdesk teams before writing code. We\’re not retrofitting generic AI tools, we\’ve built something purpose-fit for this industry.

Funding: Pre-seed £870k from Fuel Ventures, Concrete Ventures, and Antler (latest round in Dec 2025)
