Dev Ops Engineer

You'll join the DevOps Infrastructure Team, responsible for real-time distributed systems that power our trading engine-systems that are always-on, ultra-low latency, and demand resilience at scale.

You won't just be building infrastructure-you'll be crafting platform capabilities to streamline how engineers build, test, deploy, and run applications across our hybrid estate of self-hosted, co-located hardware and AWS cloud.

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

What You'll Do

• Platform Enablement: Design and maintain internal tooling and workflows that improve the developer experience across deployment pipelines, observability and testing environments.

• Empower Developers (DevEx): Automate workflows, streamline CI/CD pipelines (Jenkins, GitLab), and ensure fast, safe, and reliable deployments across environments.

• Infrastructure Automation: Build, manage, and scale Kubernetes-based microservices infrastructure on AWS using Terraform and Infrastructure-as-Code best practices.

• Developer Experience: Collaborate closely with product engineers to provide reliable, low-friction paths for development, testing, and deployment.

• Operational Excellence: Monitor, debug, and ensure the stability of our systems with robust alerting and logging using Prometheus, Grafana, and ELK.

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

• Collaborative Delivery: Participate in on-call rotations, incident reviews, and cross-functional projects with engineering and SRE teams.

• Security & Compliance: Contribute to secure system design and operational practices that support industry-standard compliance (SOC 2, ISO 27001, etc). What You Bring, * Languages: Python, Bash, Rust, NodeJS

• Datastores: PostgreSQL, Redis, Kafka

• Infrastructure: AWS, Kubernetes, Terraform, Nix, Jenkins, GitLab CI

• Monitoring & Observability: Prometheus, Grafana, ELK, Sentry
