SR2 | Socially Responsible Recruitment | Certified B Corporation™ Tech Stack

Purpose-driven recruitment group placing talent in tech, clean energy, and public services

IT Services and IT Consulting Bristol, Avon, 51–200 employees Founded 2017 Privately Held

SR2 is a B Corp recruitment firm built around impact-focused hiring—connecting engineers and specialists to roles in renewable energy, government services, and social-tech. The tech stack (Rust, C++, Python, React, PostgreSQL, Kubernetes) and project list (dbt models for energy markets, AI product development, CI/CD infrastructure) reveal an engineering-heavy organization building its own internal tools rather than purely staffing externally; the stack shape and hiring velocity (234 open roles, 115 posted in the last month) suggest SR2 is transitioning from pure recruitment services toward embedded data and AI capabilities to serve energy-sector clients at scale.
