Introduction

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%.

• Location & Work Mode: Gothenburg, hybrid 50/50 (partial remote).

• Rate Cap: 940 SEK/hour.
