Senior Backend Software Engineer

Who you are

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

What the job involves

• 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
