At Pelion
, we believe global IoT connectivity should be simple, flexible, and built for scale. We're on a mission to Make IoT Connectivity Effortless
.

We provide a complete, intelligent SIM management platform that gives enterprises the power to connect, manage, and scale their IoT deployments—from the first device to the first million. Our technology is the future-proof foundation that transforms how businesses operate, innovate, and create new value from their connected assets.

We are looking for a creative and driven Full-Stack Software Engineer to join our core Engineering team. This is a unique opportunity to work across our entire technology stack.

You won't be siloed. You will have the flexibility to:

• Build our customer-facing platform: You'll create the intuitive, responsive user interfaces that our customers use every day to manage hundreds of thousands of SIMs, monitor data usage, and diagnose device issues.
• Dive deep into the network: You'll also work on the critical backend services and APIs that communicate directly with our global network partners and core telecommunications infrastructure.
• Power our automation engine: You'll build and maintain workflows that respond to network events and customer-defined rules to optimise performance.
• Enhance our predictive analytics: You'll contribute to our data systems that help automatically detect connectivity issues before they happen and provide actionable insights.

• Front-End Development:
  • Collaborate with product managers and a diverse team to build, test, and deploy new features for our customer-facing Platform.
  • Develop intuitive dashboards, data visualisations (like data usage charts), and workflows (like SIM activation/deactivation).
  • Write clean, maintainable, and responsive code using modern frameworks like js, React or Svelte
    .
• Back-End Development:
  • Design, build, and maintain RESTful APIs and microservices that power our front-end platform.
  • Write business logic to handle complex processes like SIM provisioning, data routing rules, and billing integration.
  • Interface with our core network elements, databases (SQL, Redis), and messaging queues (like Kafka or NATs).
• Automation Engine:
  • Build and maintain automation workflows that respond to network events, device behaviour, or customer-defined rules.
  • Integrate diverse data sources into the rules engine, allowing customers to easily configure their own powerful automation logic.
• Predictive Analytics:
  • Work with data scientists and senior engineers to implement models and algorithms for predictive analytics.
  • Help develop systems that analyse large datasets to automatically detect anomalies and provide actionable insights to our customers.
• Full-Stack Responsibilities:
  • Write unit and integration tests to ensure code quality and system reliability - (we typically do Test Driven Development)
  • Participate with various empowered teams across a number of projects, help define our processes from day one!
  • Troubleshoot and debug issues that span the entire application, from a button in the UI to a database query or an API response.

• A Bachelor's degree in Computer Science, Software Engineering, or a related Science/technical field (or equivalent practical experience/bootcamp certification).
• Experience using a modern front-end framework (e.g.,
  js, React, Svelte
  ).
• Experience using a back-end language (e.g.,
  js, Python, Go, or Kotlin
  ).
• Familiarity with database concepts (SQL & No
  
  SQL) - like Maria
  
  DB and Redis.
• Knowledge of Git and version control workflows, experience with a platform such as Git Hub or Git Lab.
• Strong problem-solving skills and an insatiable curiosity to learn how things work.
• A willingness to experiment, try new things, and learn from occasional failures.

• An interest in IoT, M2M, or the telecommunications industry.
• Interest in data analysis, predictive analytics, or machine learning.
• Familiarity with containerisation technologies (Docker, Kubernetes).
• Understanding of API design principles.
