Leighton Tech Stack

AWS-native software developer for platform modernisation and data automation

IT Services and IT Consulting Newcastle upon Tyne, England 51–200 employees Founded 1992 Privately Held

Leighton is a 30-year-old UK software development firm specialising in AWS-driven custom builds and team augmentation. The hiring mix—weighted toward senior and principal engineers (8 of 10 roles), with only one junior and two data hires—reflects a services model focused on complex platform work rather than product scaling. Active projects centre on cloud-native migration, data pipeline automation, and legacy modernisation, while pain points cluster around technical debt, fragmented manual processes, and monolith replacement—the exact problems their customers bring them to solve.

About Leighton

Leighton builds custom software and modernisation platforms for mid-market UK organisations. The company operates a services-led model combining on-site team augmentation and remote delivery, structured around three service lines: software development (using React Native, Node.js, TypeScript), AWS cloud infrastructure (Lambda, ECS, Terraform, Route 53), and data architecture (Snowflake, automated pipelines). Projects range from packaging-platform overhauls to large-scale legacy-to-cloud transitions. The firm works on fixed commercial timelines and integrates with customer in-house teams and external suppliers as needed.
