Join a team modernizing core traffic-information systems (geography, traffic database, real-time). You’ll lead solution architecture and set design patterns for a scalable, secure, and maintainable platform. A key part of the role is driving a GitOps way of working where CI/CD and environment management are fully integrated into code and routines. Responsibilities Define target architecture, design patterns, and coding standards for long-lived, scalable solutions. Champion GitOps: automate build/test/deploy with GitHub Actions and ArgoCD; enable environment-as-code. Build and evolve robust back-end services and APIs for traffic information (e.g., disruptions API, train-traffic follow-up, quality assurance of planned changes). Lead on platform, security, networking, and cluster topics; support introduction/migration to new platforms. Establish logging/observability practices and service metrics (Serilog/LOKI, Prometheus, Grafana). Mentor developers; enable knowledge sharing and sound engineering practices across the team. Collaborate with stakeholders in the public transport domain to deliver reliable, compliant services. Requirements (Essential) Proven experience as a solution architect with designs that scale and stand the test of time. Containers & orchestration: Docker &/or Podman, Kubernetes (experience with enterprise distros a plus). GitHub & GitOps workflows (CI with GitHub Actions/Workflows; CD with ArgoCD). API development, integrations, and automation. .NET/C# with databases: relational (e.g., SQL Server, MariaDB) and document (e.g., MongoDB). Logging & monitoring in production environments. Traffic-information domain standards: Transmodel, NetEx, NOPTIS, SIRI. Security/network/cluster leadership and experience introducing a new platform. Mentorship experience within development teams. Bachelor’s degree in Computer Science/IT (or equivalent). Language: Swedish. Nice to Have Public transport passion and domain knowledge; interest in sustainability and mobility. Frontend familiarity (Angular or React with TypeScript; JavaScript/HTML/CSS). Search/analytics: ElasticSearch. Linux environments (RHEL9); Kubernetes on Tanzu PKS or OpenShift. Experience with railway APIs, PubTrans, and passenger information systems (PIS). Other Information Contract: Consulting assignment. Start–End: 1 Oct 2025 – 31 Jan 2027. Workload: 100%.
