We are seeking an experienced Software Development Lead with deep expertise in IoT systems, cloud‑native development on AWS, data ingestion pipelines, and API development. You will design and build the backend services that support our connected IoT devices—managing secure device communication, high‑volume data ingress, and the APIs that power our applications and customer experiences.

This role is ideal for an engineer passionate about building scalable systems that bridge the physical and digital worlds.

More about the role: 

IoT Platform Engineering

• Design, develop, and maintain backend services that support large fleets of IoT devices.
• Work extensively with AWS IoT Core, MQTT messaging, Device Shadow, and secure device provisioning.
• Build and optimise IoT communication flows including telemetry, event handling, command/control, and device state management.

Data Ingress & Telemetry Pipelines

• Architect and operate real-time IoT data ingestion pipelines handling telemetry, logs, and events from thousands of devices.
• Implement processing workflows using Kinesis, Lambda, SQS, Kafka, Step Functions, or similar.
• Ensure data quality, schema governance, and reliability across ingestion and downstream data consumers.

API Development

• Build and maintain RESTful and GraphQL APIs supporting device management, device data retrieval, and user-facing features.
• Ensure APIs are secure, highly available, and performant at scale.
• Define API standards and patterns for internal and external consumers.

Cloud & Infrastructure

• Design cloud-native systems using AWS services such as API Gateway, DynamoDB, Timestream, S3, ECS/EKS, and CloudFormation/CDK.
• Implement observability across all IoT workloads using CloudWatch, OpenTelemetry, or related tools.
• Drive cost optimisation and reliability across IoT cloud infrastructure.

Security & Device Trust

• Implement strong IoT security practices including certificate-based auth, encryption, least‑privilege IAM, and secure onboarding flows.
• Support secure OTA updates, fleet management, and device lifecycle operations.

Leadership & Collaboration

• Lead architecture discussions and mentor mid-level and junior engineers.
• Participate in design reviews, code reviews, and cross-functional roadmap planning.
• Collaborate closely with product, firmware/embedded teams, and data engineering.

Required Skills & Experience

• Backend or platform engineering experience, ideally with IoT or distributed systems.
• Strong expertise in AWS, especially AWS IoT Core, Lambda, DynamoDB, Kinesis, SQS, API Gateway.
• Proficiency in languages such as Python, Node.js, Go, or Java.
• Hands-on experience with MQTT and event-driven IoT architectures.
• Proven ability to build and scale data ingestion pipelines.
• Experience building secure, high-performance APIs for internal and external use.
• Solid understanding of distributed systems, cloud design patterns, and microservices.

Nice to Have

• Experience with edge/embedded integrations (e.g., AWS Greengrass).
• Familiarity with time-series databases (Timestream, InfluxDB, Timescale).
• Knowledge of digital twins, device simulation, or industrial IoT protocols.
• Containerization experience with Docker, ECS, or Kubernetes/EKS.
• Exposure to OTA update workflows, remote diagnostics, or fleet management tools.
