Senior Backend Software Engineer — IoT Platform

Backend Development

• Build, maintain, and improve Python/FastAPI backend services, REST APIs, and WebSocket endpoints.

• Develop features for device provisioning, fleet management, telemetry, events, device status, firmware management, and OTA updates.

• 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.

• Participate in technical design discussions and communicate implementation tradeoffs clearly.

• Share knowledge and help establish sensible backend patterns as the team and platform grow.

Required

• 5+ years of backend software development experience in production systems.

• Strong Python experience and hands-on experience with FastAPI, Django, Flask, or comparable backend frameworks.

• 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.
