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.

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.
Apply today with an up-to-date CV and a member of the KO2 team will be in touch to progress your application.
