Product Engineer

Product Engineer Product Engineer (Carrier Integrations) At parcelLab , we’re reshaping how the world’s leading brands manage the post-purchase experience. Our platform helps companies like John Lewis, Chico's, Yeti, AllSaints, and others transform every touchpoint into moments that drive customer engagement, build loyalty, and create customers for life. We’re looking for a Product Engineer , a problem-solver and builder who thrives on ownership, to join our Carrier Development Team . This team is the engine room of our platform, responsible for the vital integrations between our systems and 350+ global carriers. You will be a key player in ensuring that complex logistics data is transformed into a seamless experience for customers in 175+ countries. The role: You will own the lifecycle of carrier integrations end-to-end. This is a high-impact role where you’ll balance a "root cause" problem-solving mindset with the ability to ship reliable services. You’ll work in a polyglot environment (Python and TypeScript), transitioning between improving our long-term architecture and resolving operational challenges to keep global commerce moving. What you’ll do: Own the Integration Lifecycle: Develop, test, and maintain the services that keep our order and shipping data in sync across hundreds of global carriers. Problem Solve with Root Cause Focus: Move beyond "firefighting" to identify why issues happen. You’ll implement long-term fixes that improve system stability and performance. Iterative Building: Collaborate with internal stakeholders and carriers to clarify requirements, ship experimental solutions, and iterate based on real-world data. Integrate & Sync: Work with commerce systems and warehouse tools, ensuring that integrations (APIs/Webhooks) are idempotent, reliable, and observable. Own Quality: Instrument your services, monitor error rates in production, and "fix what you ship" to ensure a world-class post-purchase journey. What we’re looking for: Proficiency in Python or TypeScript: You are comfortable working in production with at least one of these (ideally both) and are excited to work in a polyglot environment. Database Fundamentals: Experience with relational modelling ( PostgreSQL ) and/or NoSQL ( MongoDB ). API Experience: Knowledge of building and maintaining APIs (REST/GraphQL) and working with job queues. Cloud Knowledge: Familiarity with AWS infrastructure and a desire to build observable, scalable services. Ownership Mindset: You enjoy taking a problem from concept to impact and thrive in an environment that values autonomy over "hero culture." Please note we still encourage you to apply even if you don't currently have experience with all the tech stack above. We believe in a culture of development and continuous improvement, so we would still love to hear from you! Bonus Points: Experience with Django and modern Python tooling ( uv, mypy, Ruff, Pydantic ). Exposure to the e-commerce or logistics ecosystem (Shopify Admin API, webhooks, or warehouse management). Experience with Server-driven UIs (HTMX/Alpine.js). Observability practice (Sentry, Datadog, or similar metrics and tracing tools). Our stack: (You don't need all of this) Python 3.14, Django, TypeScript, HTMX/Alpine.js, PostgreSQL, MongoDB, Redis, Celery, AWS, Terraform, GitHub Actions, Sentry/Datadog.
