Job summary

SOFTSWISS is recruiting an experienced Site Reliability Engineer for its Sportsbook team. You will work on a high-load, production-critical platform, combining backend engineering with operational responsibility to stabilize systems and improve reliability.

You will debug live issues, tune performance, and enhance observability while collaborating with cross-functional teams and external clients to ensure smooth operations.

Qualifications

• Solid Go development experience in production environments.
• Strong debugging: trace issues across services, logs, and data layers.
• Hands-on PostgreSQL: query analysis, indexing, performance tuning.
• Kubernetes experience: deployments, configs, troubleshooting.
• Familiar with observability tools (Grafana, ELK, Kibana).
• Redis for caching patterns and debugging.
• Kafka or RabbitMQ experience (consumers, lag, retries).

• Ability to own investigations and drive to resolution.

Responsibilities

• Investigate and resolve production issues across multiple services and integrations.
• Perform deep debugging (logs, traces, metrics, DB queries) to identify root causes.
• Tune system performance (PostgreSQL queries, caching, service behavior under load).
• Work directly with Kubernetes environments: deployments, configs, scaling, troubleshooting.
• Improve observability: metrics, logging, tracing (Grafana, ELK stack).
• Support and maintain integrations between Sportsbook services and external client platforms.
• Set up and configure new projects/environments (mainly Sportsbook-related).
• Write internal tooling and automation in Go to reduce manual work and operational overhead.
• Work with messaging systems (Kafka, RabbitMQ) and diagnose related issues.
• Collaborate with developers, QA, and DevOps to resolve incidents and improve system stability.
