The role:
We are looking for a Cloud Engineer to join our IT department in Bristol or London.
Simmons & Simmons is building an Internal Developer Platform to give our product teams a fast, self-service, well-governed route to ship software on Azure. This role makes security the default along that route rather than a gate at the end of it.
You’ll be the security specialist embedded in the Cloud Engineering team — the person who designs and builds the controls, guardrails and tooling that let developers do the secure thing without having to think hard about it. Just as importantly, you’ll be the connective tissue between our central Security function and the product teams: translating security requirements into platform capabilities, and giving Security confidence that the platform enforces what policy demands. It’s a build-and-enable role, not an operational response one.
You’ll work code-first and pipeline-driven throughout, mainly across Azure and GitHub, and you’ll use agentic AI as a core part of how you design, build and scale security tooling.
What will you do:
-
Be the security bridge and point of contact
- Act as the named security point of contact for the Cloud Engineering team, and the bridge between the central Security team and product teams — so security requirements turn into working platform features instead of tickets and friction.
- Represent the platform’s security posture to Security and to assurance and audit, and bring Security’s priorities back into the engineering roadmap.
- Coach and support product teams so that secure patterns become self-service defaults rather than things people queue for.
-
Build security into the Internal Developer Platform
- Help shape and build the IDP so that secure-by-default paths are the easiest paths — golden paths with controls, identity and compliance baked into the templates teams start from.
- Design and implement guardrails as code: policy-as-code, identity and access patterns, and the automated checks that keep the estate compliant by construction.
- Make evidence a by-product of the platform, so assurance and audit can be satisfied from what the pipelines already produce rather than from manual evidence-gathering.
-
Own security tooling and best practice across the IDP
- Select, integrate and operate security tooling across Azure and GitHub — pipeline security gates, code and dependency scanning, secret detection, and posture management — so checks run automatically and block non-compliant changes from progressing.
- Define and document the engineering standards and reusable patterns the wider team and product teams build on.
- Continuously improve the security baseline across the estate as the platform and the threat landscape evolve.
-
Apply agentic AI to security engineering
- Use agentic AI tooling as a core part of how you design, build, analyse and scale security work — for example to accelerate policy authoring, change-impact analysis and validation.
- Help the team adopt agentic AI safely and effectively, establishing the patterns and guardrails for using it well within an engineering workflow.
-
Build and run the platform on Azure
- Design, build and operate the core Azure platform the IDP runs on - landing zones, networking, identity, and the shared services product teams depend on - as reliable, self-service capabilities rather than bespoke, ticket-driven infrastructure.
- Deliver infrastructure as code: reusable Bicep/Terraform modules, pipeline templates and golden paths that let teams provision compliant Azure resources without reinventing the foundations each time.
- Own the operational health of the platform - observability, cost management, resilience and lifecycle/upgrades - so the estate stays secure, performant, and well-governed as it grows.
- Partner with product teams to evolve the platform from real consumption, turning recurring needs into paved, supported capabilities instead of one-off solutions.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What we are looking for:
Essential
- Demonstrable experience securing cloud platforms in production, with strong hands-on Azure depth (identity and access, networking, governance).
- A code-first way of working: infrastructure and policy as code, and confident use of GitHub (or equivalent) with CI/CD pipelines as the primary delivery mechanism.
- Practical experience embedding security into pipelines — scanning, policy gates, secrets management — so that controls are automated rather than manual.
- Hands-on experience embedding SAST (Static Application Security Testing) and DAST (Dynamic Application Security Testing) into CI/CD pipelines, including triaging and tuning findings and enforcing them as policy gates.
- Hands-on use of agentic AI tooling in an engineering context, and a clear point of view on how to apply it well and safely.
- The communication and relationship skills to work as a genuine bridge between a central security function and delivery teams, explaining security to mixed technical audiences and influencing without authority.
- A platform-as-a-product mindset — treating developers as customers and measuring success by adoption and reduced friction, not just controls shipped.
Desirable
- Experience in a regulated environment (legal, financial or professional services) and familiarity with the assurance and audit evidence that comes with it.
- Specific Azure and GitHub security tooling: Microsoft Defender for Cloud, Microsoft Sentinel, GitHub Advanced Security, Entra ID PIM and RBAC, Bicep, PowerShell.
- Policy-as-code frameworks (for example Azure Policy or Enterprise Policy as Code) and OIDC-federated pipeline identity.
- A relevant degree is preferable but not required — we care more about what you can do than where you learned it.
