Are you a Senior Software Engineer ready to pivot into Security and Identity?
Do you want to apply your software engineering expertise to real-world security challenges?
Would you like to build and own critical identity infrastructure used across a complex enterprise environment?
Are you ready to step into a role where software engineering comes first, and your development skills are the foundation?
If so, this is worth a conversation.
Senior Software Engineer →
Entasis Partners are working with a leading technology-driven organisation in London that is expanding its Security Engineering capability, with a strong focus on Identity and Access Management (IAM).
This role is designed for a Senior Software Engineer who wants to pivot into security engineering while remaining deeply technical. You will work within a high-performing engineering environment where identity, authentication, and access control systems are treated as mission-critical infrastructure.
You will play a key role in designing, building, and scaling secure identity platforms, working closely with engineering, infrastructure, and security teams to deliver resilient and automated solutions.
Why This Role Stands Out
- Security engineering first , not governance or policy
- Real engineering ownership of identity platforms
- Opportunity to pivot from software engineering into security
- High-impact work on critical infrastructure
- Strong technical culture with modern engineering practices
- Clear progression into Security Engineer / Security Architect pathways
This is a hands-on engineering role focused on building secure, scalable identity systems and integrating them into enterprise platforms.
Key Responsibilities
- Design and build secure identity and authentication services
- Develop and maintain identity platform functionality using Java or similar languages
- Engineer integrations across enterprise systems and cloud environments
- Implement and automate identity lifecycle processes (Joiner–Mover–Leaver)
- Build secure APIs and identity-related services
- Troubleshoot and optimise identity platform performance
- Support production systems and respond to security-related incidents
- Contribute to security architecture and engineering decisions
- Drive automation and reliability across identity infrastructure
- Collaborate with platform, DevOps, and security teams
Core Experience
- Strong software engineering background
- Experience building scalable backend systems
- Solid understanding of system design and architecture
- Experience working with APIs and integrations
- Strong debugging and problem-solving capability
Security / Identity Exposure (Helpful but Not Essential)
- Identity and Access Management (IAM)
- Authentication and authorisation systems
- Active Directory or LDAP
- Cloud platforms (AWS, Azure, or GCP)
- Access control or identity workflows
You will work with Java, REST APIs, cloud platforms, Linux, CI/CD, and identity protocols (e.g. SailPoint).
