Smarkets is transforming the betting exchange space by delivering world-class technology and the best-priced markets in the industry. With over £29 billion in traded volume since 2010, we’ve built a product-led, transparent, and fair platform that challenges the norms of traditional betting.

As a Series B tech company, we pride ourselves on engineering excellence, lean product thinking, and scientific rigor. With a close-knit team and a passion for innovation, Smarkets is where top talent comes to make a real impact.

Now, we’re looking for a DevOps Engineer to help scale our infrastructure and empower our developers with streamlined, self-service tooling and operational excellence.

You’ll join the Cloud Infrastructure Team, responsible for real-time distributed systems that power our trading engine—As a pivotal team member, you’ll craft and maintain scalable, secure, and high-performance cloud-based systems—while building the platforms that empower our developers to move fast, deploy confidently, and scale effortlessly.

You won’t just be building cloud infrastructure—you’ll be crafting a highly autonomous environment where ownership is expected, experimentation is encouraged, and innovation is embedded into everything we do. You'll shape the foundation of our cloud-native stack, blending visionary infrastructure architecture with the practical realities of a high-growth, high-scale environment.

This is a role where infrastructure meets engineering productivity: part DevOps, part Platform, 100% mission-critical.

• Design and Own Infrastructure: Architect and maintain robust, cost-effective, and secure infrastructure on AWS using Terraform, Kubernetes, and cloud-native best practices.

• Champion Platform Engineering: Build and evolve the internal developer platform (IDP) that empowers engineers to self-serve infrastructure, CI/CD, observability, and security tooling.

• Debug Production Systems: Triage issues across layers of the stack—Kubernetes, cloud services, networking, applications, data pipelines—and drive root cause analysis and resolution.

• Drive DevOps Practices: Implement infrastructure as code (IaC), observability, alerting, and environment provisioning to support engineering teams and production systems.

• Promote Engineering Excellence: Establish and uphold standards and best practices across infrastructure, operations, and software delivery.

• Scale Microservices Architecture: Lead the buildout of resilient Kubernetes-based microservices across environments, optimizing for cost, performance, and security.

• Own Security & Compliance: Take point on security posture and audits (SOC 2, ISO 27001), ensuring our platforms meet rigorous compliance and operational standards.

• System Reliability: Optimize performance and availability for high-throughput, low-latency services that power the betting exchange.

• Be a Force Multiplier: Mentor other engineers, drive cross-team alignment, and lead initiatives with broad technical and business impact.

• Networking & Security: Proficiency in VPNs, VPC peering, DNS, TLS, and identity management (OIDC/SAML).

• Observability & Operations: Experience with Grafana, Prometheus, ELK stack, Sentry, and building robust monitoring/alerting pipelines.

• Developer Platform Tools: Hands-on with GitLab CI/CD, Jenkins, Backstage, or similar IDP tooling to build cohesive internal platforms.

• Data Infrastructure: Experience supporting PostgreSQL, Redis, Kafka, and object storage like S3 in production environments.

• Process & Compliance: Familiarity with security frameworks, incident response, RBAC/least privilege models, and compliance workflows.

• Experience with platform engineering concepts like golden paths, self-service portals, or PaaS-style abstractions.

• Built or contributed to developer enablement or SRE tooling platforms.

• Prior experience scaling platform infrastructure in a fast-growing startup environment.

• 6+ years in cloud infrastructure, DevOps, or platform engineering roles.

• Proven ability to balance long-term vision with short-term execution.

• A collaborative spirit that uplifts others and fosters strong technical culture.

• Passion for reliability, scalability, and simplicity in infrastructure.
