• Secure endpoints with OAuth 2.0, JWT validation and proper input checks.
• Implement background jobs and event consumers using Kafka, SQS or RabbitMQ.
• Tune slow queries, add indexes and read query plans.

What we're looking for:

• Comfort reading logs, metrics and traces to debug problems in production.
• Working knowledge of message queues or streaming platforms.
• Strong SQL and relational data modelling skills.
• Understanding of concurrency, transactions, idempotency and retries.

Rate: ISK 1,800,000 - ISK 2,100,000/month

• Occupational pension.
• Five weeks of annual leave.
