We are working with a secure public-sector programme delivering mission-critical digital services used at national scale.
They are looking for an experienced Software Engineer/Developer with strong cloud-native engineering skills to design, build, and operate modern systems in highly regulated environments.

This is a hands-on engineering role - you will be writing production code, working closely with infrastructure, and contributing across the full delivery life cycle.

Please note: Due to the nature of the work, active SC or DV clearance is mandatory.

• Designing and building cloud-native applications on AWS

• Defining and maintaining infrastructure using Terraform

• Working across the full SDLC: design, build, test, deploy, and operate

• Collaborating with product, platform, and security teams in agile delivery

• Supporting secure, scalable, and resilient systems in production

• Contributing to CI/CD pipelines and operational best practices

• Working on systems that matter - national services, defence, or critical infrastructure

• Active SC or DV clearance (non-negotiable)

• Strong experience as a Software Engineer/Developer

• AWS (eg Lambda, ECS/EKS, EC2, S3, RDS, API Gateway)

• Python used in production environments

• Terraform (infrastructure as code)

• Experience building APIs and Back End services

• Familiarity with CI/CD pipelines and cloud deployment

• Comfortable working in secure or regulated environments

• Experience with FastAPI, Flask, Django, or similar frameworks

• Exposure to Front End technologies (React, Next.js, Angular)

• Experience with containerisation (Docker, Kubernetes)

• Background in public sector, defence, or government programmes

• Understanding of DevSecOps and cloud security best practices

• Experience supporting live services at scale

• Work on high-impact, nationally significant systems

• Modern cloud and engineering practices

• Highly skilled, clearance-holding engineering teams

• Flexible working arrangements (where clearance allows)

• Competitive day rate or salary (dependent on clearance and experience)

Due to the security requirements of this role, applicants must already hold active SC, SC Enhanced or DV clearance. Unfortunately, we cannot sponsor clearance for this position.
