We’re looking for a Senior Dev Sec Ops  Engineer to join our Dev Sec Ops  team, reporting to the Engineering Manager (EM) and working closely with product engineering squads and platform teams. This role is hands‑on and high‑impact, focused on strengthening our pipelines, infrastructure, developer experience, and overall security posture. You'll take ownership of delivering secure‑by‑default tooling and automation that removes friction and accelerates shipping.

The Dev Sec Ops  team partners across the business to make the secure path the easy path - through clear guardrails, self‑service tooling, great documentation, and CI/CD enablement. We’re a collaborative, remote‑first group driving programmes that improve platform reliability, uplift engineering practices, and reduce operational risk. You’ll help us deliver these initiatives while raising the bar on cloud security and operational excellence.

• Design, build, and maintain automation, tooling, and integrations that improve developer workflows and embed security into CI/CD.

• Leading improvements across our cloud infrastructure, ensuring environments are secure, observable, resilient, and repeatable.

• Implementing and optimising security tooling (SAST, SCA, DAST, secrets management) to provide fast, actionable feedback to developers.

• Utilise Infrastructure as Code (Terraform) and CI/CD (Git Hub Actions) to manage cloud resources, deploy platform components and enforce consistent configuration.

• Enhancing observability across our systems with structured logging, dashboards, alerts, and SLOs that help teams understand and operate their services safely.

• Collaborating with product and platform teams to define secure patterns, participate in design discussions, provide guidance, and support incident response where needed.

• You have strong engineering experience in Node.js or another modern backend language, and you're comfortable building reliable, secure automation or platform tooling.

• You have solid experience with Infrastructure as Code (Terraform) and CI/CD (Git Hub Actions), including secure secrets management and automated deployments.

• You understand AWS fundamentals - networking, IAM, ECS/Lambda, logging/monitoring - and can apply secure‑by‑design principles to cloud systems.

• You care deeply about observability and have hands‑on experience implementing structured logging, monitoring dashboards, and SLOs.

• You collaborate well: you participate in design reviews, pair with engineers, and write documentation that makes life easier for the next person.

• Experience with cloud‑native security patterns - such as least‑privilege IAM design, secure network boundaries, or defence‑in‑depth controls

• You rely on a lot of top‑down direction. Here, you’ll have a lot of freedom and ownership of your role, and you’ll be expected to shape your own progression

• You’re not comfortable working in a fast‑paced environment. Our speed and scalability are what set us apart; you need to be able to act quickly and think on your feet

• You struggle to follow through on ideas. We value people who do what they say they will. If you care about something, you have the freedom here to make it happen

• You don’t like change
  . You’ll get on great here if you relish the ambiguity of rapid growth and are willing to embrace…
