InPost Group is an innovative European out of home deliveries company, revolutionizing the way parcels are delivered to customers. With operations across several countries, our network of intelligent lockers provides customers with a fast, convenient, and secure delivery option. InPost Group is a publicly traded company, with a market capitalization of about $5 billion as of March 2023. With over 10,000 people worldwide, InPost Group is one of the largest out of home delivery providers in Europe, committed to providing sustainable and efficient delivery solutions to meet the evolving needs of customers in today's rapidly changing landscape.
We are currently hiring Senior Engineers for two different teams:
1. InPost Pay - a comprehensive e-commerce solution offering a unified platform for payment and delivery. InPost Pay allows users to pay and arrange delivery with one button on the product card, transferring the basket and order to the InPost app. It simplifies the shopping experience by consolidating payments, deliveries, and order tracking into a single app, eliminating the need for multiple emails and messages from different stores
→ Hybrid model: 1 day per week from the office in Warsaw or Kraków, remaining days remote
2. Merchant Portal - a new, InPost-owned platform that serves as a central hub for all merchant-facing services. This covers the full merchant journey: onboarding, shipping, and access to other InPost products. The team acts as a core/platform team, meaning they provide shared services and infrastructure consumed by other InPost teams.
