This is an exciting opportunity to work at the intersection of hardware and software-developing backend services that enable secure device communication, high-volume data ingestion, and the APIs that drive customer-facing applications.
You'll be responsible for building and evolving the backend platform that supports large fleets of IoT devices, with a strong focus on scalability, reliability, and security. Working within a collaborative engineering environment, you'll also contribute to architectural decisions and mentor other developers.
Key Responsibilities:
- Design, develop, and maintain backend services for IoT platforms
- Build and optimise real-time data ingestion pipelines handling high-volume telemetry and events
- Develop secure, scalable RESTful and/or GraphQL APIs
- Architect cloud-native solutions using AWS services (IoT Core, Lambda, DynamoDB, API Gateway, etc.)
- Implement observability, reliability, and cost optimisation across cloud infrastructure
- Ensure robust IoT security practices, including secure device provisioning and communication
- Lead technical discussions, support code reviews, and mentor junior team members
- Collaborate with cross-functional teams including product, embedded, and data engineering
Key Skills & Experience:
- Strong backend or platform engineering experience, ideally within IoT or distributed systems
- Deep knowledge of AWS Technologies (IoT Core, Lambda, DynamoDB, Kinesis, SQS, API Gateway)
- Proficiency in Python, Node.js, Go, or Java
- Experience with MQTT and event-driven architectures
- Proven track record of building scalable data ingestion pipelines
- Experience developing secure, high-performance APIs
- Solid understanding of microservices and cloud design patterns
Desirable:
- Experience with edge/embedded integrations
- Familiarity with time-series databases
- Knowledge of digital twins or industrial IoT protocols
- Containerisation experience (Docker, Kubernetes/EKS)
- Any experience in a technical leadership or team leader role.
This is a fantastic opportunity to join a forward-thinking team working on cutting-edge IoT solutions, with the chance to make a real impact on product direction and technical strategy.
