Senior Software Engineer - Cloud Services

About this role

Join Simbex as a Senior Software Engineer - Cloud Services and help build and modernize the backend systems behind our connected-device and sensor-analytics platforms. Our work lives where hardware meets software in demanding, real-world settings including connected safety and sports-performance products where device data has to be captured reliably and turned into trustworthy insight. You will own significant parts of a cloud platform that ingests real-time device data, exposes it through well-designed APIs, and supports the analytics products our customers depend on.

Key Responsibilities

• Lead design and evolution of the backend services and REST APIs that ingest, route, and serve device sensor data, balancing day-to-day delivery with long-term platform health

• Build and operate serverless services on AWS: primarily Lambda, API Gateway, and managed databases for scalable, cost-efficient cloud workloads

• Help modernize the platform toward event-driven patterns, introducing asynchronous messaging and streaming (e.g., SQS/SNS, Kinesis, or Kafka) where they improve reliability and scale

• Design and optimize relational databases (PostgreSQL on RDS) for high-throughput sensor data storage and demanding query workloads, applying solid schema design, indexing, and performance tuning

• Define and maintain clear API contracts between internal services, device clients, and external platform consumers

• Implement authentication, authorization, and security best practices across APIs and cloud services (OAuth 2.0, API Gateway, IAM)

• Instrument services with structured logging, metrics, and distributed tracing to support observability and proactive incident response

• Drive engineering maturity: CI/CD, automated testing, and code-quality standards. Lead design reviews as part of the team's formal review process

• Write clean, modular, well-tested code (unit, integration, and contract tests) and set the standard for quality across the codebase
