SoCode Limited; Cambridge; On-site; GBP 90,000 - 130,000; Full time

Job summary

SoCode Limited is hiring an Enterprise Security Architect to sit between architecture and engineering on a major on‑prem Private Cloud build. You will shape security foundations of a brand‑new private cloud, built with open‑source stacks and modern platform engineering practices, embedding security across the stack.

You’ll threat‑model the platform, define secure designs, validate controls, and implement DevSecOps with automated tests, hardened configurations and auditable evidence, working

Qualifications

• Proven experience building private cloud infrastructure, not just public cloud.
• Strong background with open‑source infrastructure stacks, containers, and platform technologies.
• Hands‑on security architecture and engineering across large‑scale datacentre or hybrid environments.
• Expertise in threat modelling and attack‑path analysis.

Responsibilities

• Own and evolve threat modelling across the platform, infra, workloads and onboarding pathways.
• Translate threat stories into engineering requirements, acceptance criteria and delivery priorities.
• Drive secure‑by‑design through IaC, CI/CD, policy‑as‑code and hardened image pipelines.
• Define reusable standards for identity, privileged access, secrets, PKI, segmentation, logging and recovery.
• Translate NIST/STIG frameworks into pragmatic, testable controls.
• Automate posture, evidence and continuous validation across the platform.
• Act as the security conduit across engineering, programme leadership and enterprise security.

Job description

We’re hiring an Enterprise Security Architect to sit right between architecture and engineering on a major on‑prem Private Cloud build. This isn’t a public‑cloud security role — you’ll be shaping the security foundations of a brand‑new private cloud infrastructure, built using open‑source software stacks and modern platform‑engineering practices.

The RoleEmbedded full‑time within an engineering‑led programme, you’ll be the dedicated security partner — threat‑modelling the platform, defining secure designs, validating controls, and embedding DevSecOps across the stack. You’ll work directly with architects and engineers to turn threats into real mitigations, automated tests, hardened configurations and auditable evidence.

Key Responsibilities

• Own and evolve threat modelling across the platform, infra, workloads and onboarding pathways.
• Translate threat stories into engineering requirements, acceptance criteria and delivery priorities.
• Drive secure‑by‑design through IaC, CI/CD, policy‑as‑code and hardened image pipelines.
• Define reusable standards for identity, privileged access, secrets, PKI, segmentation, logging and recovery.
• Translate NIST/STIG frameworks into pragmatic, testable controls.
• Automate posture, evidence and continuous validation across the platform.
• Act as the security conduit across engineering, programme leadership and enterprise security.

What You’ll Bring

• Proven experience building private cloud infrastructure — not just consuming public cloud.
• Strong background with open‑source infrastructure stacks, containerisation and platform technologies.
• Deep hands‑on security architecture + engineering experience across large‑scale datacentre or hybrid environments.
• Strong threat‑modelling and attack‑path analysis skills.
• Practical knowledge of compute, virtualisation, containers, orchestration, storage, networking and platform management.
• Experience with IaC, CI/CD, policy‑as‑code and hardened image pipelines.
• Expertise in PKI, secrets, privileged access, segmentation, workload isolation and infra hardening.
• Ability to define reusable patterns, measurable criteria and security standards.Experience with automated testing, attack simulation and vulnerability management.
• Credibility to influence multidisciplinary engineering teams and balance risk vs delivery
