About Shippo

At Shippo, our vision is bold and clear: we are the shipping layer of the internet. Our mission is to make every merchant successful through excellent shipping, delivering world-class logistics technology and infrastructure. We’re building the backbone of global e-commerce — connecting merchants to carriers worldwide through a single API and intuitive dashboard.

As a remote-first and globally distributed team, we believe flexibility fuels trust, autonomy, and performance. Our diverse perspectives — across continents, cultures, and time zones — drive our innovation and enable us to build solutions used by businesses everywhere. We invest in modern, scalable technology so our teams can build, ship, and iterate with confidence.

Your impact starts here: every person at Shippo plays a direct role in shaping the infrastructure that powers global commerce and makes shipping simpler for businesses around the world.

How we will deliver success together: We are looking for a Backend Engineer (L4) to join our Carrier Capabilities (CCAP) Team. The CCAP team builds and maintains integrations with shipping carriers worldwide, enabling reliable rating, label creation, tracking, and related capabilities across domestic and international shipments.

In this role, you will focus on building and maintaining carrier integration pipelines using our established integration framework and workflow orchestration tools. You will work primarily at the integration and pipeline layer—implementing carrier-specific logic, request/response mappings, validation rules, and business workflows—while partnering with the Carrier Integrations Platform (CIP) team for lower-level infrastructure, distributed systems, and messaging concerns.

You will operate with clear technical guidance and mentorship from Senior Engineers and your Engineering Manager. You are expected to independently deliver well-defined carrier pipelines and integration features while contributing to team discussions and continuous improvement. This role is designed for engineers who want to deepen their expertise in integration design and workflow orchestration before expanding into broader platform ownership.

Shipping & handling responsibilities

• Design, implement, test, and maintain carrier integration pipelines within the existing integration framework.
• Build and evolve carrier-specific workflows using orchestration tools (e.g., Kestra or similar), focusing on correctness, clarity, and maintainability.
• Implement carrier API integrations (REST, SOAP, or similar), including request/response transformations, validation, and error handling.
• Write reusable, modular Python components aligned with established integration recipes and patterns.
• Contribute improvements to integration recipes and documentation to make new carrier implementations more predictable and consistent.
• Own the end-to-end quality of your carrier integrations, including automated tests, release validation, and production monitoring.
• Systematically debug pipeline failures and carrier-specific issues, documenting findings and escalating to CIP when issues relate to lower-level infrastructure (e.g., messaging, distributed systems, or cloud platform concerns).
• Use AI tools in daily workflows to improve development speed, test coverage, debugging efficiency, and documentation quality.
• Apply critical analysis to identify recurring carrier integration challenges and propose incremental improvements to code, workflows, and documentation.
• Participate actively in code reviews, design discussions, sprint planning, and incident reviews.
• Contribute to CI/CD practices and automated testing to ensure safe and predictable production releases.
• Participate in the team’s on-call rotation and respond to integration-related incidents with urgency and ownership within your scope.

Your shipping requirements

• 3+ years of professional software development experience.
• 2+ years working with production code in Python.
• Experience building and maintaining backend services or API integrations in production environments.
• Experience implementing workflow-based or pipeline-driven systems.
• Experience in consuming and integrating with third-party APIs.
• Experience writing reusable code and shared components to improve maintainability.
• Solid understanding of object-oriented programming and common design patterns.
• Strong debugging skills and ability to perform root cause analysis within integration workflows.
• Demonstrated use of AI tools as part of daily engineering workflows to improve productivity and quality.
• Ability to critically evaluate existing implementations and suggest pragmatic improvements.
• Strong written and verbal communication skills.
• Ability to understand business context and how integration quality impacts customer experience.
• BS or MS degree in Computer Science or equivalent practical experience.
• Experience with at least one server-side framework (e.g., Django, FastAPI, Spring, Rails, Phoenix).

Bonus

• Experience with workflow orchestration tools such as Kestra, Temporal, Prefect, or similar.
• Experience working with shipping or logistics carriers.
• Experience implementing complex request/response mappings or data transformation pipelines.
• Familiarity with integration patterns such as adapters, translators, and routing.
• Understanding of distributed systems concepts, with the ability to collaborate effectively with platform engineers handling cloud infrastructure, workflow, and messaging systems.
• Interest in improving the reliability and predictability of carrier integration pipelines.
