The posting

Connectivity, IoT Core, & SIM Lifecycle

On behalf of our customer Circle Gas we are seeking a Mid-level Software Engineer to join their Virtual Device team. This team is the heartbeat of our operation, responsible for the interface between our smart devices and our applications. In this role, you will help build the "nervous system" of their IoT network.

You will work heavily with AWS IoT Core to manage telemetry ingestion and command structures, ensuring their digital twins accurately reflect the physical state of millions of meters. A specific focus of this role will be managing the lifecycle of SIM cards and ensuring robust meter connectivity.

As an Software Engineer, you will be expected to own the delivery of features within your team, write and debug code that affects large parts of our systems, and actively participate in design discussions.

Key Responsibilities

  • Core Development: Write, test, and deploy high-quality code (Python & TypeScript) for their virtual device microservices using AWS Serverless technologies (Lambda, DynamoDB, etc.)
  • IoT & Connectivity: Implement and maintain telemetry ingestion pipelines and command/control interfaces using AWS IoT Core
  • SIM Lifecycle Management: Build and refine the logic for managing SIM card activation, deactivation, and status monitoring to ensure uninterrupted meter connectivity
  • System Reliability: Ensure the production readiness of your code; monitor telemetry flows and debug connectivity issues across the fleet
  • Collaboration: Work closely with firmware engineers and the data team to understand data payloads and ensure seamless integration
  • Team Growth: Actively contribute to the Circle Tech culture, participate in code reviews, and share knowledge with the team
  • Infrastructure as Code: Utilize Terraform to manage and deploy infrastructure, ensuring repeatable and secure environments

Qualifications

  • Experience: Proven experience in software engineering (typically aligned with L4 expectations: delivering features independently and understanding the broader system)
  • Tech Stack: Strong proficiency in Python and/or TypeScript
  • Cloud Native: Hands-on experience with AWS Serverless architectures (Lambda, API Gateway) and EventDriven Design
  • IoT Knowledge: Experience with AWS IoT Core or similar MQTT-based telemetry systems is highly desirable
  • Mindset: You thrive in a maturing "scale-up" environment—you are comfortable with some ambiguity and eager to help establish better processes

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
