If you’re driven to build category-defining technology and want to shape the future of offline communications, join our high-caliber team and help us transform how the world sends mail.

About The Team

The Logistics Operations team builds the critical infrastructure that automates and optimises the physical movement of mail. We design reliable, scalable systems for carrier selection, routing, order fulfilment, and tracking, partnering with Operations and Product to translate complex logistics challenges into elegant technical solutions.

What you’ll do

As a Software Engineer on the Logistics & Operations team, you will design, develop, and maintain the backend services and APIs that drive our global offline communication platform. Your work will impact business efficiency and support large-scale physical mail delivery across continents.

Your Responsibilities

• System Architecture: Architect, develop, and maintain logistics-related backend services and APIs, including routing, batching, carrier selection, and SLA management.
• Scalable Systems: Build and maintain systems that manage delivery workflows across our network of print and mail fulfilment partners.
• Automation & Efficiency: Optimise internal tooling and automate manual interventions to streamline shipment tracking and delivery exception handling.
• External Integration: Design and implement integrations with external carriers and fulfilment APIs (e.g., FedEx, USPS, Royal Mail, Canada Post, etc.).
• Operational Excellence: Own production systems, monitor for and resolve bugs, delays, or bottlenecks in the fulfilment pipeline.
• Cross-Functional Collaboration: Work with Product and Operations teams to translate business requirements into technical solutions.
• Code Quality: Participate in code reviews, architecture discussions, and infrastructure planning to uphold quality and maintainability.

You are a pragmatic problem-solver with a strong backend background and a passion for solving real-world logistics challenges. You are comfortable building scalable systems and understand how software can drive operational efficiency. You collaborate effectively across departments to deliver impactful solutions.

• 3+ years of backend software engineering experience, ideally with Node.js, Python, or similar.
• Proven experience building RESTful APIs and integrating with complex external systems.
• Solid understanding of distributed systems, job queues, and microservice architectures.
• Hands-on experience with SQL and NoSQL databases (e.g., PostgreSQL, MongoDB).
• Strong debugging and performance optimisation skills.
• Ability to write clean, maintainable, and well-documented code.

Preferred Qualifications

• Experience with logistics, shipping APIs, or supply chain systems.
• Familiarity with warehouse management systems, SLAs, or order management platforms.
• Exposure to task queuing and event streaming tools like RabbitMQ or Kafka.
• Knowledge of monitoring and alerting tools such as Datadog, New Relic, or Sentry.
