Senior Backend Software Engineer (IoT Platform)

We are looking for a Senior Backend Software Engineer to help build and maintain the backend platform powering our connected-device products

You will work across cloud services, APIs, data pipelines, fleet management, and real-time device communications

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

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

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

In your first 90 days, you will have mapped the current embedded software architecture, identified the highest-priority gaps, and shipped at least one meaningful feature end-to-end

Within six months, you will have established a team testing standard, introduced measurable improvements to firmware reliability, and built strong working relationships with hardware and systems engineering- This is a hands-on role for an engineer who enjoys building production systems, solving practical problems, and working closely with embedded, hardware, frontend, and product teams

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 Git workflows, CI/CD, code review, and production deployment practices

Clear communicator who can work effectively across engineering disciplines

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

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

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

Experience designing and building REST APIs

Experience with Linux

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

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

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

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

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

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

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

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

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

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