A profitable London tech scale-up of around 90 people is looking for a Senior DevOps Engineer to join a small, high-impact team supporting a platform used across 30-40 million devices in the US. Working with carriers and device manufacturers, they deliver personalised content and notifications at massive scale, processing billions of daily events across a highly distributed AWS and Kubernetes environment.
Joining a team of three DevOps Engineers and a Head of DevOps, you'll be responsible for maintaining and improving Kubernetes infrastructure, managing a self-hosted observability stack, owning CI/CD pipelines, and contributing to architecture and R&D initiatives. Upcoming projects include platform personalisation, edge computing, and preparing the infrastructure for future global expansion.
The environment is mature, heavily automated through Terraform and Terragrunt, and focused on continuous improvement rather than firefighting. They're looking for someone who has operated Kubernetes in production at genuine scale within a fast-moving startup or scale-up environment.
Non-Negotiables- Kubernetes (K8s)
- AWS
- Terraform
- Open-source observability – (Grafana, Prometheus, Loki, or equivalent at scale)
- Startup, scale-up or fast-growth background
- Kubernetes - multi-tenant clusters, 5 production, 7 total including non-prod
- AWS - primary cloud
- Terraform and Terragrunt - standardised IaC across all clusters
- Grafana, Prometheus, Loki, Sentry - self-hosted observability and tracing stack
- Redis - self-hosted within Kubernetes as the caching layer
- GitHub, Jenkins - CI/CD pipelines
- ML and AI workflow pipelines - part of the personalisation platform build
- GCP - minor secondary cloud exposure
- Distributed tracing at scale
- Edge architecture or CDN delivery experience
The team is at a real inflection point technically. Three substantial pieces of work are either already in motion or close enough to matter for the person joining now.
The first is an edge architecture migration. The platform was originally built for low-powered devices, with all processing handled server-side. That model is being rearchitected to push delivery closer to users - CDNs, edge nodes, content configurations shifted out of the backend. It involves real problems to solve around authentication, Android connectivity, and latency optimisation.
The second is a personalisation engine. The business is investing heavily in understanding user signals and behaviour to serve more relevant content. That means new ML workflows, data pipelines, and close collaboration with a large data team.
The third is longer-horizon - global expansion, multi-region infrastructure, disaster recovery across regions - off the back of new partnerships with major device manufacturers. The groundwork starts now.
Career progression is structured rather than theoretical. Everyone on the team is currently senior, but as the team grows the plan is to bring in mid-level engineers and give the senior team the option to grow into technical lead roles - or, where the appetite is there, into people management.
Employee Benefits- Profit share scheme - typically 10-20% of salary when the company beats its financial targets (paid out last year)
- Private medical and dental cover
- Mental health and wellbeing support
- WellHub membership - access to gyms, spas, and saunas across the UK
- Fortnightly in-office haircuts, including women's cuts (the stylist has her own salon near King's Cross)
- Wednesday office breakfasts and regular lunch and learns
- Office stocked with snacks and drinks, ping pong, projector and movie nights
- Annual company off-site - this year was four days in Mallorca
- New, larger London office in the pipeline for late 2026
