About the Company

- Experience with message and job queues such as Bee Queue, SQS or similar
- Solid logging and observability practice across structured logs, metrics and alerting
- Proven experience with AWS services and a real understanding of AWS networking
- Comfortable working at pace in a small, high trust team
Nice to Have:
- Exposure to IoT systems including firmware interaction, physical device constraints and connectivity debugging
- Experience with real time mobile app communications
- API versioning and backward compatibility experience
- A track record of scaling systems through periods of significant growth
