Senior Backend Software Engineer — IoT Platform

Your mission

Build a reliable backend platform for connected devices. Keep telemetry, device status, and OTA updates running at scale. Improve API speed, uptime, and data quality with every release. Move quickly from incident to fix and keep the platform steady as the fleet grows. Build a culture that ships working features and fixes problems fast and grow a team that delivers on time

What you will own

Backend development. Build, maintain, and improve Python and FastAPI services, REST APIs, and WebSocket endpoints.

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

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

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

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

Test and quality. Write unit, integration, and end-to-end tests alongside feature development. Participate in code reviews and keep the code clear and maintainable.

Production reliability. Investigate and resolve production issues across APIs, databases, cloud infrastructure, and device integrations. Improve telemetry ingestion through retries, idempotency, monitoring, and error handling.

Lasting corrective action. Containing production issues fast. Find root causes and verify that fixes prevent recurrence.

Engineering practices. Help improve CI/CD, logging, metrics, and operational documentation. Share knowledge and help set sensible backend patterns as the team and platform grow.

Cross-team delivery. Work with embedded, hardware, frontend, and product teams to deliver end-to-end features. Communicate implementation of tradeoffs clearly in design discussions.

Measurable results. Own clear, tracked targets for the platform. Keep telemetry ingestion reliable, with no duplicate processing. Maintain API uptime and response times. Make OTA rollouts succeed at a high rate. Reduce the time to resolve production incidents. Keep test coverage high and deploy often and safely.

What you bring

Backend software development experience in production systems.

Strong Python skills and hands-on experience with FastAPI, Django, Flask, or a similar backend framework.

Strong PostgreSQL and SQL skills, including schema design, migrations, query optimization, and data lifecycle management.

Experience with AWS or a comparable cloud platform. Hands-on AWS experience is 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.

Experience Linux.

Clear communicator who works effectively across engineering disciplines.

A plus, but not required

Cloud-connected IoT, device management, or telemetry systems, AWS IoT Core, IoT Jobs, Device Shadows, or IoT fleet provisioning, firmware OTA or fleet-management platforms, Redis, RDS Proxy, queues, or stream processing, AWS CDK or Terraform, familiarity with embedded systems or wireless communications, security-focused systems or audit logging, and experience in aerospace, satellite, industrial IoT, or other mission-critical environments.

What success looks like

The platform stays reliable as the fleet grows. Telemetry arrives once and on time. OTA updates roll out safely. Incidents get fixed and stay fixed. Teams ship features end to end, and your engineers grow.
