• Design and maintain PostgreSQL schemas, migrations, indexes, queries, and data-retention strategies. 

• Build and improve data-ingestion services using AWS IoT Core, MQTT, Lambda, RDS, Redis, and S3. 

• Work with infrastructure-as-code and deployment tooling to maintain cloud infrastructure. 

Quality and Reliability 

• Write unit, integration, and end-to-end tests alongside feature development. 

• Investigate and resolve production issues across APIs, databases, cloud infrastructure, and device integrations. 

• Improve the reliability of telemetry ingestion through appropriate retries, idempotency, monitoring, and error handling. 

• Participate in code reviews and contribute to clear, maintainable engineering practices. 

• Help improve CI/CD, logging, metrics, and operational documentation. 

Collaboration 

• Work closely with embedded, hardware, frontend, and product teams to deliver end-to-end features.

• Strong knowledge of PostgreSQL, SQL, schema design, migrations, query optimization, and data lifecycle management. 

• Experience with AWS services—or comparable cloud platforms—with hands-on AWS experience preferred, especially EC2, Lambda, S3, Cognito, and infrastructure-as-code. 

• Experience with MQTT, WebSockets, message-driven architecture, or real-time data delivery. 

• Experience designing and building REST APIs. 

• Strong automated-testing skills, including unit, integration, and end-to-end testing. 

• Experience with Git workflows, CI/CD, code review, and production deployment practices. 

• Clear communicator who can work effectively across engineering disciplines. 

• Experience with Linux. 

Nice to Have 

• Experience building cloud-connected IoT, device-management, telemetry, or other event-driven systems. 

• Experience with AWS IoT Core, IoT Jobs, Device Shadows, or IoT fleet provisioning. 

• Experience building firmware OTA, device telemetry, or fleet-management platforms. 

• Experience with Redis, RDS Proxy, queues, stream processing, or event-driven architectures. 

• Experience with AWS CDK, Terraform, or other infrastructure-as-code tools. 

• Familiarity with embedded systems, wireless communications, or sensor-rich hardware. 

• Experience with security-focused systems, audit logging, or operational compliance. 

• Experience in aerospace, satellite, industrial IoT, or other mission-critical environments. 

Additional Requirements

This is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.
