# Staff Software Engineer

- **Company:** Dex Technologies, Inc.
- **Location:** United States (Remote available)
- **Contract:** Permanent contract
- **Skills:** Artificial Intelligence, Data Migration, Relational Databases, Software Design Documents, PostgreSQL, MySQL, Node.Js, Software Systems, TypeScript, ReactJS, Large Language Models, Backend, Front End Software Development

## About the Role

* Demonstrated track record as a Staff or Lead Engineer owning complex, mission-critical systems end-to-end from problem definition through to production.
 * Deep hands-on expertise across the full TypeScript ecosystem, specifically Node.js on the backend, React on the frontend, and relational databases like PostgreSQL or MySQL.
 * Proven experience deploying pragmatic AI, LLM tooling, or agentic workflows that hold up under real production load, rather than toy prototypes or research experiments.
 * Startup or scale-up experience with high ambiguity, where you have driven architectural decisions based on operational reality and business outcomes rather than abstract ideals.

## Description

This business is rebuilding the UK residential lettings market by executing an aggressive roll-up strategy. Rather than selling software to legacy letting agencies, they acquire them outright, transition their entire landlord and tenant books onto a unified AI-powered platform within eight weeks, and automate decades of operational manual work. Backed by top-tier global venture firms with tens of millions in funding through Series A, their model creates an immediate, direct line between software delivery and bottom-line revenue.

You will take technical ownership of one of three core engineering domains: Tenant Find, Property Management, or Payments. This is not an ivory-tower advisory seat where you write design docs and delegate execution; you will stay in the code, partner directly with product to deconstruct legacy operational edge cases, and ship production agentic systems. If you want to run pragmatic automation that solves real-world logistics rather than theoretical problems, this is that seat.

The work

 * Architect, build, and scale an entire vertical domain end-to-end, translating messy, legacy agency workflows into clean, resilient software systems.
 * Deploy pragmatic AI and agentic systems into production to automate complex tenant management, financial reconciliations, and maintenance logistics.
 * Design and streamline data migration and platform infrastructure to support rapidly porting newly acquired agency portfolios onto the platform in under two months.
 * Write production-grade TypeScript across the full stack while setting technical direction, reviewing architecture, and mentoring engineers as the team scales.
