Senior DevOps Engineer (AWS) – Start-up – London

Shape the DevOps strategy of a fast‑growing London start‑up.

We’re partnered with a high‑growth, ~40‑person tech company working with major global brands in the consumer/data/SaaS space. Their engineering team is small, collaborative and ambitious — and they’re looking for a Senior DevOps / SRE / Platform Engineer to take ownership of their AWS infrastructure and set the direction for how they build, scale and secure their platform.

This is a rare opportunity to be the senior DevOps voice in the room, working closely with the CTO and Engineering Manager, and mentoring their current DevOps engineer.

Why this role is exciting

• Total ownership of their AWS environment and infrastructure roadmap
• Direct influence on technical strategy, resilience, scalability and cost optimisation
• A genuinely strategic role, not just “keeping the lights on”
• High impact in a low‑ego, high‑trust engineering culture
• Work closely with the CTO, shaping long‑term infrastructure decisions
• Greenfield improvements across observability, CI/CD, security and Kubernetes

What you’ll be leading

• Own and evolve their AWS estate (EKS, RDS, S3, Lambda, IAM, VPC etc.)
• Manage and harden Kubernetes (EKS) clusters + microservices
• Re‑architect CI/CD pipelines (GitHub Actions)
• Build a full observability stack — Grafana, Prometheus, CloudWatch/OpenTelemetry
• Drive cloud security best practice (IAM, network security, secrets, vuln scanning) as they move toward SOC

What they’re missing today and where you fit in

• A proactive DevOps leader who can turn a task list into a clear roadmap
• Proper monitoring, alerting and cost‑management across 100–200+ AWS services
• A senior engineer confident making decisions and reducing dependency on the CTO

Their tech environment

• AWS‑centric with heavy Kubernetes (EKS)
• Terraform, Docker, GitHub Actions
• Strong scripting in Python / Go / Bash (JS/TS helpful)

Who they want to meet

• Experienced DevOps / SRE / Platform engineers running production systems
• Someone who talks in terms of strategy, roadmaps, optimisation, not just tools
• Comfortable in growing, fast‑paced start‑up environments
